- In this video I continue with assembling the fuselage, including finishing cutting and shaping the new firewall, setting the firewall and bulkheads or formers up so the fuselage sides can be assembled to form the basic fuselage shape. It takes time to set all of the pieces up straight so that the fuselage will be straight and true. I use 30 minute epoxy and CA glue to construct the pieces.
The Balsa USA Smoothie kit is a 40 class (size) sport plane and has been around for a long time and is still readily available on the Balsa USA website. Balsa USA also have a larger version of the plane called the Balsa USA Smoothie XL. I will be using an OS Engines 46 AX2 glow engine to power it and Futaba S3004 servos, receiver, and 6J transmitter.
For this balsa kit build I use traditional rc plane kit building techniques. In each build series episode I will focus a different aspect of the build including the wing, fuselage, tail section rudder and elevator, engine mount, landing gear, tail gear, engine set up (OS Engines .46 AXII), fuel tank, servos and receiver (Futaba), control rods and horns, Monokote covering, carving and shaping wood, using CA glue (Zap CA glue, Starbond CA glue), epoxy (JB Weld, Bob Smith Industries, Z-poxy finishing resin), tools and everything thing else involved with building a radio control plane kit (RC Airplane kit).
I have been building, flying, crashing, modifying, and repairing radio control planes (RC Planes) for many years and enjoy sharing what I do with the radio control plane community, so I started RC Plane Tech channel for fun. I am not an expert, there are many different techniques to building radio control planes. A good way to learn about flying and building rc planes is to see what others are doing, that's what I do and that's why I like to share what I do. Thanks for watching my channel. Have fun!
Thanks for the baking soda trick for plywood .
Sure thing, glad it helps
Sempre un buon video dove si impara la precisione di assemblaggio
Thanks!!
You know the saying goes, if you can fly 1/2A, you can fly anything.
Yup
As a DIYer doing just about everything in the home from building rooms to cabinets that speed square is indispensable. I use it for common things like quickly drawing lines on 2x4s to be cut if I'm not using a compound miter saw.
Ya I need to learn what it’s capabilities are. I do some stuff also. Ill learn more about it.
@@JamesRCPlaneTech My recent project was installing laminate flooring. I kept it on my belt with me. I use a compound miter saw so I didn't really need to draw lines on the boards, only needed tick marks but I did lines anyway. Here's the funny thing. I never considered using it for building rc planes!
Thats cool. i do a lot of stuff like that around the house. I just built a pergola where I probably could have used it but its on my rc table, lol.
Hi, I noticed in this video that the FIRE WALL has no angle on it that I can see like you cut in previous videos, is there an angle or is it completely square all the way around? Like the original fire wall is.
Hi, The firewall had no angle built into it per the plan. So I used washers to angle the engine mount, and set it off center a little to the right so the prop was centered.
Really liking this series. I’ve got the XL version (89”) of this plane tucked away for a future build. Also, I know you were looking for an RPM 25L. There is one on eBay right now. Sorry, I don’t know how to put links in the comment section.
Hi thanks. The XL is a big plane, it looks really nice and is probably a better kit than this one. That will be a nice build I think. And yes, I did notice that 25L and there is a 15S, both are on the pricy side. Thanks for pointing that out to me, Ill keep an eye on it, but I don’t think I can spring for it right now. Good luck with the XL, that should be fun.
👍
Thanks again for pointing those kits out to me.
Page 22 of the instructions calls for 1 to 2 degrees of right thrust for P-factor and to offset the engine 1/16" to the left so the prop shaft is centered in the nose. The plan view of the fuselage shows a corresponding offset of about 2 degrees to the right.
Since you needed to relocate the firewall on your build, how did you adjust your engine mounting location for right thrust? Thanks
Hi, so that was a little trial and error. To start with, the OS 46 with the mount I used barely fit within the area and I had to trim the inner left side doubler in order to get it to shift to the left. So that was the first problem is that when I was trying to put the few degrees of right thrust I didn’t have room to then shift the engine over. So as I mentioned above I trimmed the left side so I can make the shift to the left. Then as for the few degrees thrust, I just estimated. Im not sure how accurate one can measure 1-2 degrees. I used thin washers under the left side bolts to angle it to the right. So basically, I taped the washers on the back of my mount, while holding the mounting against the firewall I figured out where to mount the engine relative to the spinner(about 1/16 in gap between backplate and nose of plane), temporarily mounted the engine, then I marked the centerline on the end of the plane so I could judge where to line the prop shaft, and used a lot of eyeballing to check and recheck, once I got it where I thought it needed to be I traced the engine mount and holes on the fire wall. I wish I could say there was an easier way to do it, but I don’t know. Even if you left the firewall where it is on the plan, you would have to monkey with it because the engine length from one engine to next may be different. So just moving the engine forward or backward on the mount would cause shifts in where the prop shaft center would end up.
I think the key is to get your engine mounted on the mount relative to the spinner (the gap), then start playing with the left mount shift local and fee degrees on thrust line. I bet there are a lot of smart people out there that have better ways of doing it. But I just had to play with it until I thought it looked right. I hope all this helps. Sorry I may not have a clear description.
So I looked at video number 21 and 22, (engine mount part 1 and 2) and its a long two videos but I try to explain it. Mostly in the later half of video 22. Hopefully all this helps. Let me know if I can clarify what the heck I did!
@@JamesRCPlaneTech OK thanks!
Sir plz sizes of planes
Hello, the size of this plane is 52 inch wing span. This is a 40 class size plane, meaning it uses about a .40 engine or about that size. Im using the OS .46 AXII
