I didn't prime and I'm here in Colorado. The priming you've done looks outstanding - but IMHO I think it's overkill.
Thanks for showing your work and thank you for the tipps. All the best. Chris
Thanks for the vids. Watch the EAA one hour long vid about the 916. He talks about the changes to the engine for longevity based on their inspection of the 915 engines. Based on what he says, I think it is highly unlikely that the TBO will be extended for the 915. $10K extra is a big hit, but it will payoff on resale (I think). My quick build 916 kit arrived in Torrance about two weeks ago. With builder's assist I should be flying by next May. Rick.
Some comments/questions: The “missing” pieces. Backordered? Or on the inventory as shipped but you didn’t receive? Discovered during inventory? I had a number of backordered parts during my build. But never a part shown as shipped that I didn’t receive. Some backordered parts I received somewhat quickly. Others not so much. There’s a lot of work you can do with the front fuselage section. It’s at least as much work as the tail you’re showing in the video. Maybe more. You're discovering exactly what I've mentioned before. Unlike the wing and empannage kits and KAI's, the fuselage KAI leaves a little to the imagination and doesn't have every rivet or detail. My kit has the coolant based heat exchanger on the inside for the heater. But I'm not installing the "spider" duct arrangement. By all accounts, doesn't work that great. I'm going to have only cool vent on the instrument panel and rear side wall. Then heat with new ducts to the front and back in the center console. Will use some 3D printed parts. Many are making this change. Maybe something you also may want to look at? There’s no question Sling kind of expects you to buy all the kits at once because you’re right there are some parts called out that are in different kits. But I didn’t order the FWF kit until after the fuselage. I had to do a couple workarounds and Cleco stuff temporarily until the FWF kit arrived. But it didn’t stop me from basically completing the fuselage. I ordered the fuselage, canopy, undercarriage, and upholstery (because of the lead time for the upholstery) at the same time. I wouldn’t have done it any differently. The canopy is a huge part of the fuselage build. Surprised you haven’t ordered. It will stop you much sooner than the FWF. I entertained the 916 for my build. But couldn’t get over the increased cost. Plus since I already had the 915 cowl, engine mount, etc. the added cost was more than just the engine. There’s no question the 916 is basically required for the high wing. The low wing performs very well with the 915. The 1200 TBO is an issue I guess. But as an experimental, you’re not locked into that. I assume you know that.
@@paulborror2544 it’s interesting, the bulkhead for example was not on the inventory list, not in the crate, but required. This is a situation I’ve seen a few times now and for me is due to kit changes such as updates to newer parts. For some reason the parts end up omitted. I do have the canopy crate, it’s currently the other work surface, I will also run the heater duct mod to the rear seats. I’m one of the first with this new heater arrangement so we’ll have to figure out what’s happening as we go. There is hope, I’m aware a new version of the manual for the fuselage is coming. As everyone has indicated, there’s a lot of issues with this current version. For instance, one I caught - on rib assembly 2, the forward most one, the instructions keep insisting to rivet parts into the holes where the center ribs mate up. If you follow that blindly, you end up with 4 of the 6 ribs blocked, so - 16 rivets you’d have to drill out. I’m doing the same as you in some areas, basically cleco’ing parts and I’ll also leave myself painters tape notes. You’ll see me shift as well to the center section as well in the coming videos ;)
I’m pretty much at the same stage as you In the build. I’m also finding the Kai is not as good as the wing and emp ones so I’m double checking everything with the high wing manual for parts that are the same as that manual seems a lot more complete. I also have the new heater, which again only appears in the HW Kai. What parts from the firewall forward kit do you need to get a rollling chassis? Like you I’m yet to order my FF kit as I thought I could get it up on its wheels before that and then make the call to go either 915 or 916. I also have a few parts missing plus a few on backorder and so will also grind to a halt fairly soon. PS the gaskets were great, thanks.
@ awesome! Reach out to sling technical. They can share some of the new manual pages for the heater system and throttle quadrant. My desire on the firewall is to get the heater system installed, battery box, plus the support channel and the coolant mount angles. Ends up being 5-6 parts, but with that I would feel comfortable to put on the firewall foam and the engine mount.
which size microstop did you get from panamerican? part number? Besides #40 which other bit sizes did you get?
@@attashay 5/8 capacity. Part is 19-360. I also have a 1/2 120 degree with #21 pilot for 4.1mm counter.
Good day indeed. How was the order to delivery day and maybe the shipping day?
@@MateuszPerlak, this was ordered 6 months prior. Once in slingshot, I had good tracking of it with anticipated dates and cargo ship information. Sling arranged final transit which can vary, but in the US takes approximately a week.
Fun with fuel caps. The fuel tank flanges are not keyed, so you can mount them in any orientation. The fuel cap is keyed to fit only 4 ways. So if you fit the fuel cap assembly with the flange only to keep things clean, we’ll check your orientation and make sure those notches are facing the front / back and to the sides of the tank and not sideways.
I just noticed Edward Hefter's TSi at 5:25. He is with The Airplane Factory in Torrance. Maybe he can organize a group for Air Venture for next year.
Nice progress. The best part of building the tanks is when they're done and successfully tested. 🤪 One hint. I see you have you're garage door open so you are getting ventilation. But the mfg does recommend a respirator. Can't hurt. Some not nice chemicals in that stuff.
100% Garage is always open and there's a box fan circulating air. Some things I also do is to stir outside and on these bigger batches the door stays open and the fan stays running through the day.
Thanks very much for the video! Hope next year, the TSI numbers will be doubled.
The bolts, spacers, and eyebolts for the ailerons are easy to install into the completed assembly. There's a hole in the end rib to put the bolt in with an extension. Don't need to reach the other side since there are nut plates. I did mine that way and it was no big deal. I agree it's confusing they reference those parts in the wing KAI. But they are in the finishing kit and very straightforward. I'm a little surprised Sling didn't explain that when you ordered the parts. I'd recommend finishing the ailerons so you can get the entire wing assembly wrapped up. Two other things: Highly recommend gluing those strips to the underside of the wing spar before assembly. I used dots of JB Weld. Enough to hold them in place before the rivets are set. Makes life a lot easier putting that together. Finally, I've had zero issues with my Milwaukee gun pulling the large rivets, including 4.8 and SS. In fact I like it better than the air tool for the large rivets. I leave the 3.2 nozzle in my air riveter since those are the high volume ones. Agree it's faster although I don't know about 4x. 😀
Thank you for sharing this experience, how long wait was the order to shipment?
This part was about 2 weeks, but was available at Sling in Torrance. Parts from South Africa tend to take 45 days or so.
Hello chubby friend haha
加油👏
How important is it to epoxy the rivnuts? I see that you pretty much always epoxy rivnuts. I am looking for further knowledge on this.
Its basically recommended practice. If one of those rivnuts slips loose and starts to spin while you're loosening or tightning a screw, you're in a bad spot. Some people do swap them for anchor nuts, which are rivetted in place and this is what you'd see more in vans builds as well.
Very cute! They do that typically to warn other squirrels of danger! Thanks for sharing! ❤🐿
Thanks for posting progress - I am far from starting a build, but gathering info on how to. I also run into this video recently posted - th-cam.com/video/hcgxCII6JpA/w-d-xo.html - and I am in between if to use prime painting inside or not.
Welcome to the great debate. I’d probably say this. You’re not priming for you, you’re priming for your grand children. I do it because you have the best opportunity when it’s all exposed. I believe it adds value and it does protect. This plane will fly, it will take me to places, I may spill a drink or two that could cause problems, it will spend time outdoors when it’s at destination airports and it will see coastal locations. This is a great metal, but I think it’s worth the extra hours, it’s also, at least to me fairly enjoyable and I like the color. ;)
Hi Greg did you prime with the Transtar 6183 that you mentioned in a previous video? Rattle can? Would you still recommend it for aircraft?
Indeed! I’ll have a full video on priming in just a couple of days.
Beware of the barking squirrel. 😂
After comparing the two aircraft, despite the higher initial cost, I'm purchasing the Sling TSI first!
Nice videos. Thank you for putting then together. I see your internal parts are primed. What are you using for the primer? Is it rust-oleum rattle can self-etching or something else? Also, how is the finish holding up to the “build beating”?
So far so good. I've had 2 inside edges flake and honestly its because I missed scuffing those spots before I primed. A touch up application solved it. I'm using Transtar 6183, and it came out to be 7 cans to completely paint the empennage.
Ahhhh - good memories of me making my first "why I am building Sling".. Nice overview!
I’ve noticed in a few other sling tsi builders videos, they use 4 rectangular tables/ workbenches to work on. Do you have a recommended size for the tables or is there a forum that speaks about them? Just looking to get more info as I prepare for my kit to arrive. Also do you park Tesla out side the garage and then run the charging cable under the door?
The build tables are "EAA Build Tables" I did add the outdoor carpet to the tables and added more support to the shelf. I highly recommend some adjustable feet, just because garage floors are not level. Some pics of the build under my workshop entry - eaabuilderslog.org/?s=Sling Yes to the Tesla as well. It got kicked out with the kit arrival. It has a chance to go back in the garage once I fully uncrate the wing kit.
Lower quality aluminum???? They use mostly 2024-T3 with Alclad, which is a much higher quality aircraft aluminum than is used on some other manufactures' models -- and is far LESS likely to corrode without any additional protection. Where did you get your misinformation from?
There's quite a bit of references with a search for 2024-t3 vs 6061, however, callouts you'll note 2024 is stronger, but more prone to.... cladding helps mitigate... however, you're also drilling holes all over it. The builders in my area all tend to prime it. We have all seen plenty of examples of production aircraft where its fine bare 30-40 years, some add on corrosion-x, whatever. Both are good metals when treated appropriately, Sling builders have a higher level of confidence, by some percentage points on topic, I'll leave it at that.
How would someone navigate to this page? Is there a portal that sling or TAF will allow you access to?
In my case, Sling contacts you and welcomes you as a builder once the first kit order is received. That usually includes an invite to the portal to track crates and order parts when needed.
Thank you for your good videos
Thank you!
Deburred holes before riveted?
yes, as part of my steps when i remove the plastic and initially tool the parts as needed. Slings parts have been pretty good on burs. I have had a few that I've spent more time with and some that I've only had to touch a few seconds. You get to a point pretty quickly when you run your hands along the parts and feel it and theres an obvious way the light reflects off a hole that needs to get a few spins of the debur tool. 99% of the time as well, 1 side of the peice is perfect and the other side is what needs just a bit of attention.
Congrats!!!! The first rivets are very special!! Only 20.000 left.. 😂👍👍
The collection jar has started for the spent mandrels, seeing it fill up has also been rewarding. I'll show its current status on an upcoming video ;)
I've been enjoying watching your build videos. In my experience, I use a fresh red scotch brite and isopropyl alcohol BEFORE dimpling to clean and achieve the mechanical etch. 320 sandpaper might be too aggressive, especially on a power wheel. Using the scotch brite before dimpling allows the area around the rivet to also get etched. Otherwise you are skipping the entire dimple and it will have no etch. Just my 2 cents... Keep up the good work!
Thank you! This is something I'll adjust on on the wing skins. I plan to do those skins soon as the table is cleared up. On the sand paper, the 320 isn't that much more agressive than the scotchbrite. To compare the maroon scotchbrite 7447 pad is in the 320-400 grit range. The painters will likely use as rough as 240, depends a bit on the painter. 6444 (brown) is in the 240 range, and 6448 (green) is in the 600 range.
@@gregbuildsplanes Good information. On my previous build, I used the red scotch brite exclusively for the chemical and mechanical etch as instructed by Stewarts Systems (paint). The primer and paint went down perfectly for me with no scratch through. I only used a lower grit (320) lightly during between the prime and top coats.
Thanks for posting the video. Appreciate the comments and discussion. Question: Do you do the same for the inside of skin?
Shouldn't this countersink be done with the dimple die since it's sheetmetal?
Negative. This material is too thick for a dimple and the instructions clearly state to countersink.
I'm curious to know the difference between the aluminum you speak of between the two and how you got this information. Mostly Kaiser 2024-T3 aluminum in both kit types. Why is one better than the other? Corrosion is usually an issue in bonding different types of material together. Such as aluminum against steel. It's not the quality of aluminum.
there's a good reference commentary on the sling forums - www.slingpilots.com/forum/viewtopic.php?t=49
As stated in the linked video, the aluminum used in the Sling is 6061-T6. Higher corrosion resistance that 2024. There are a handful of steel parts in the Sling kit and they come finished. Paint or powder coat. Not sure. SS rivets are used in a number of places, there they show using a corrosion coating. I'm using ECK corrosion control.
@@paulborror2544 So you depict the quality of aluminum by corrosion resistance?? 2024 is far superior over 6061 in tensile and shear strength. About 40% stronger. That is why 95% of Alum aircraft are built from it. The only benefit to 6061 is the price (it's cheap). Marine grade 5052 is the most corrosion resistant if that's what you guys think matters. Use it.
@ro838 I'm not going to get into a social media contest. You said Slings were made from 2024. They're not. You brought up some galvanic corrosion concerns with dissimilar metals and I responded with what Sling has in their build manuals. One of the big discussions with these builds is whether to prime, alodyne, whatever, the aluminum. That was the subject of the provided link and what I referenced. I'm not a metallurgist and can't speak to the technical differences between 2024 and 6061. I am a customer and trusting the experts at Sling designed their airplane taking 6061 characteristics into account. You have every right not to be a customer and suspect you won't. I'm out.
@@paulborror2544 Okay, Over and out! You referenced the link in which (another guy on the internet) states 6061 is superior over 2024. Well, It is not. Also, I'm not against the Sling, I think it's a cool plane. In the video he states the same mis-information about the material. That is why I made the first comment in the first place. It will be just fine.
Nice job! I considered making a comparison video like this, but didn't want to get bogged down in arguments with RV owners in the comments. 😆 Bottom line, they're both fine airplanes, as you say. Here's a few points I might add, for anyone else deciding between these two planes: Build and cost: While it's true (or at least WAS true) that the basic Vans kit is cheaper, it takes more hours to complete. If one wanted to compare apples-to-apples, the Vans "quick build" kit takes the same number of build hours to complete as the Sling "slow build" kit. So, if you compared the Vans quick build kit price to the Sling slow build kit price, their cost advantage disappears. And for those going with build-assist, those extra hours the RV-10 build takes will translate into extra dollars. Plus, as you mentioned, the Sling kit is more complete. Once you buy popular third-party interior kits (seats, sidewall upholstery, center throttle quadrant, overhead, etc.) and other options that most RV-10 builders buy to modernize the look of their plane (wing tips, cowling, etc.), you're spending far more on the Vans. And finally, with their recent 30% increase of kit prices, there's no longer any way anyone can say an RV-10 will be cheaper, even without the third-party options. Performance: RV-10 owners will remind you that they can decrease their fuel burn down to 10 - 11gph by running LOP. That's true, but then their cruise speed will be more in the 155 KTAS range, pretty close to the Sling TSi at ECO power. Conversely, a Sling TSi pilot can run at max continuous power and cruise at 165 - 170 KTAS (in the high teens) while still burning only 10.5 - 11gph . So, pretty darn close in terms of cruise performance. Also, while the RV-10 shows a higher initial ROC on a SL standard day, the Sling TSi's turbo means we'll do better in hot & high conditions, and will retain our ROC better as we go up in altitude. So again, in real-world, pretty much a wash. At the end of the day, you'll end up with an awesome airplane whichever way you go. Happy building!
Thank you, couldn't agree more. both great planes and I've learned a ton from the vans community.
Looking good! I noticed by the time you did the main wing box, you were wearing gloves. Good call - that metal around the crates gets to be very sharp!
💖 *promosm*
I can see that the hand squeezer is WAY easier to line up the holes, and therefore quicker. Any chance you could normalize the music volume with your voice volume on future videos? You speak pretty softly, but then the music comes in and blows out my ears.
yes! thanks for this feedback. I'm working with a different editing software, so lets see where this goes on the next video.
You can dimple without pulling the plastic film away. Works fine and the rivets fit OK after pulling the film off later. I have my empannage and wings done doing them all that way. Evan talks about this in his videos. Hopefully you are reviewing those during your build. I've found them a gold mine. You're more patient than me only pulling part of the film like that. Wait until you get into the size of the wing skins. I agree the film may provide a little bit of protection for scratches or whatever. But I've found the skins are easy to dent. That's the main thing you need to guard against and the plastic won't help.
Agreed, Evan's are fantastic.
Can't wait for my kit to arrive next month!
Congratulations! Great job for just you, one person to get all boxes to your garage! You must be excited and ready to start building! More vedios coming? My quick build kit is coming in May.
