Hi Lee Great video and review of the Recon 35, I have yet purchased a quad that uses the 18650 batteries, I figured it was to heavy to do anything. Now that we have two things would be better. And it sounds like it does. Thanks again for the video and information.
love you video. i buy one after watching your great video and as a newbie i flash firmware without backup. your dump file help me out. thx a lot. and keep great work. i also buy a T -1 after watching u review. happy flight!!
and i got a question. i buy hd version with ELRS, i found when i change to CRSF, GPS will gone. i turn it back Sbus( which will lost ELRS control) GPS will back again . any solution about that?
@@Painless360 elrs CRSF working fine but GPS only. CRSF and GPS cant work together. one work fine other will down. asking HGLRC hope can solve. Thank for reply.
Looks like there isn't a compass. Why don't they put a compass, only a minor increase in cost with much better capability. I think the only rekon with a compass may be the rekon7. Cheers.
I do like this style of flying/drone. This seems a bit better of a design than the original for sure. I imagine the 30G lighter analog version would fly even better. Looks like you could hdzero in at least the digital frame if not the analog. Thanks for reviewing!
It makes more sense as a 2s set up and the flight time is not to bad either. I wish they would fit a compass then you have the choice of inav etc and use the spare uart, I know its easy enough to add a compass and gps to the spare uart but it would be nice to have the choice. Stay safe Lee
Been waiting for the reviews to come out about this quad. I think its perfect for a particular niche. Just wanted to find out about flight characteristics in wind and motor power. But throttle percentage at hover seems adequate. I'm planning on picking one up for a 'everyday carry' as the 18650's won't need to be nursed in and out of storage and can be charged from a power brick. Also it might be ideal for my trip to Jamaica in a few months for a wedding.
@@nmnmnm35 I've just got back from Jamaica, took 4 lipos 8 18650's 2 18500 2 usb power packs, plus all the build in batteries in cameras and laptop etc. I had no problem, just make sure they are in your carry on and not under the plane.
7:31 is this an action cam or DJI stream? it looks like there are some odd vertical letterbox compression artifacts. Are the artifacts visible on the raw footage or is this just youtube compression?
DJI Goggle DVR. Those smudges at the edge are due to the middle of the image being prioritised for sharpness. See my DJI tips and tricks video... Happy flying
DC 9V "power module"? What's that? Backup power with a separate small lipo? Also, at 5:45: GPS on soft serial 1, "means not going to be able to run iNav" - why is that? No input for compass or barometer? Thanks Lee. EDIT: Is the "power module" a voltage regulator?
Lee: Thanks for all of your Good Work!! Iam sure you did a video on the batteries for this unit. What do you recommend? I have learned the hard way they are Not Created Equal! Thank you in advance for your replay to this. Ben Herr - USA PS. The tip on marking the holder and the Tape on Positive end is Great as well1
Wouldn't 4" bi-blade props on 1404 (or even 1603) be more efficient than 1303.5 with 3-blade props? I've seen some guys flying 25+mins on 2S 18650 with 4"...
4 inch need bigger motors like 1404 or 1603. With 1303.5 its made as light as possible. They could swing 4 inch, but probably not perform well. Going up to 4 inch and with 1404 motors, wo will need a slightly bigger, more durable frame, which weighs more. So you see its a snowball system with weight
4" 2S is just much more difficult to get sub 250. With a small action cam its basically impossible. All flight time gains through larger disc area are also pretty much lost due to extra weight unless the motors are so small it fly's horribly. It's the same with all quads I tested; keeping battery size constant, an increase in disc area doesn't increase flight time unless you also keep the weight pretty much constant by using small motors, which in turn ruins the flight feeling
@@DaveCFPV Thanks for the answer, but if I plan flying lightweight LR (without action cam and dig. system), is it possible to run Rekon35 on 4" bi-blade with 1404 / 1603s?
@@DaveCFPV why are you not building with naked vista and nebula pro nano or polar nano (with adapter to 19mm) ? I see many manufacturers are doing that already. Too hot?
Painless360 great review again. I hope more and more people become aware of your channel and your subs continue to climb. You put out some great content. Learned alot from your channel. I was wondering if you'd be willing to make a video on using elrs receivers in fixed wings without the use of FC boards. How to use products like the matek crsf to pwm boards and other options and I'd also love to know if it's possible to connect elrs receiver to Kopilot lite using crsf protocol. Not alot of info out there on newer elrs stuff for use in fixed wings. Thanks again
Be aware that ELRS only has 4 full resolution channels at the moment so will support only simple fixed wings. CRSF to PWM adapters will work the same was as on Crossfire or Tracer and there should be more content for those systems on the setup. Matek sell a PWM reciever for ELRS that is a great idea for fixed wing. Finally, Kopilot only understands PWM or SBUS so you can't use the CRSF protocol with it. SBUS support out of of the ELRS is something that a lot of people have asked for... Happy flying!
I may have asked you this question already but I am going to write down this time. What do you think would make a really good flight controller for fixed wing and helicopter that is compatible with spektrum equipment/receivers?
Lots of things to consider as it depends on what software you need to get the model to do what you want. th-cam.com/video/ZwCLdkjqM-Y/w-d-xo.html covers a lot of it.. Best of luck
Anybody else getting GPS problems. When I seem to get Lock the sats go down to zero or I never get a lock at all. Running crossfire and dji hd. Flies great with molicell 3000 35a batts but would rather have a working buzzer than a non-working gps. Might have to swap gps for buzzer.
You'll need a low baud rate GPS unit running this soft serial config. I replaced it with the Flywoo GM8 v2.0 GPS which supports baud rates all the way down to 9600bps. At that rate it works flawlessly. Plug is the same but wiring needs remapping.
The purpose of high amp capable cells is to reduce voltage sag, so can make use of most of battery capacity (Ah), not amps (A). This not free style quad.
I've bought a couple 18650 battery holders for other projects. And indeed, the "cheap" ones have low amp ratings. But is IS possible to buy these holders with the tabs rated for "high" amps.
Just put a damn diode between the tabs of the battery holder. Simple yet perfect solution to prevent powering it the wrong way around… Sorry, not you, Rekon should’ve done that And they should come up with an HDzero version as well.
From the copy on the linked webpage - "Unfortunately, diodes performing well enough to serve as a reverse polarity protection without significantly impacting performance simply don’t exist." Happy flying!
@@Painless360 thank you for that, interesting point to make. I’m going to question that with my co-workers from electrical, curious to see what they say. I’ll get back to you on this if they disagree. Still want to see an HDzero version though! Great channel, keep up the good work!
@@JekleFPV I don't see why we wouldn't offer HDZero Versions in the future when it gets more widely adopted. For now the demand is probably still to small to justify producing BNF with the associated minimum order quantities and cost.
It's true that 18650s don't always offer longer flight times. They are however pretty convenient and and have some advantages for long range flying. Discharge behaviour is more linear and they don't tent to have a sudden voltage collapse below 3,3V like lipos do. Basically you can still "limp home" between 3 and 2.5V when you push it too far while a Lipo powered quad basically drops out of the sky at some point
Nice open-box review. Will be interesting to hear more about Rekon35 as you get access to more nice weather days.
Fantastic flying and review, Lee! 😃
Pretty impressive little quad! I loved it!
Stay safe there with your family! 🖖😊

Hi Lee , thanks for the review. Must be very windy on this flight maybe it´s worth to upgrade on BF 3.x. Stay save and Painless(-:
Thank you.
Hmm rekon35 or diatone f35 .. complete opposite but wondering if 4s li-ion on f35 work to have it fly longer when I want

Agreed. It would be a simple addition and make for a far more capable, versatile explorer. I'll keep on at them! :D

More of a step-up/constant voltage generator than a BEC. Happy flying!
Doubled the batteries but only 12+ minutes ?
It isn't the battery capacity that makes that difference, it is the extra weight..
They're in series = double the voltage not mah

It does like Serenity! However, this quad isn't for me.
Would have been better if the included the m80 pro GPS so it could run iNav without needing anything else out of the box.
i just ordered a Jumper T Pro TX and a review said to use an " unprotected " 18650 battery , is there a reason not to use a " protected " 18650 ?
I'd ask the person who wrote the review what they mean. Best of luck

This is neat, but what I want to know is it true that chewing tobacco helped Gunner Cooper shoot the predator with Painless?
He probably didn't think about it. He didn't even have time to bleed!!
What? I get 12 mins on a 1000mah 3s on my toothpicks with a lipo.
I worry that the battery bay contacts are not well suited for 30A current.
The purpose of high amp capable cells is to reduce voltage sag, so can make use of most of battery capacity (Ah), not amps (A). This not free style quad.
Doesnt mean it will draw 30A. But on a freestyle quad, yeah I would worry too
I wouldn't class this as a freestyle quad - see video.
I've bought a couple 18650 battery holders for other projects. And indeed, the "cheap" ones have low amp ratings. But is IS possible to buy these holders with the tabs rated for "high" amps.
It's not available for indian market
Lots of things aren't due to shipping issues. Why not start a local RC reseller for your country? Happy flying.
Would the model 3 handle two rcr123A type batteries
they need it to land on a station that automatically changes the batteries and use them as security cameras always flying around.
Stop trying to empty out my wallet.

How does the GPS perform on your model? I got the drone, and here it performs very poorly. Only getting 6 Satellites after 10 minutes or so...
Mine is sluggish too... Happy flying
Nice review!
Not sure if 12 minutes is exceptional though….. I have a 3.5 inch rig with a Caddx vista /nebula pro that gets 11 minutes on a 4s 850.
its great if you have a bag full of cheap fully charged 18650 batteries

I agree, I had a 12min flight time with sub250g AOS3.5 with 1404 3800kv and a 850mAh 4S Tattu r-line… and was not wobbling like that…
