It's hot, so I'm gonna mess with the cockpit for a while.

Observer is all printed, I'll attach the arms after I smooth him out some.

It took some fiddling to get him right. While the plane is listed at 1:8.5, the seat is closer to 1:11.

He started out as a 1:6 figure I got off Thingiverse, scaled down by 55%. His head comes from other work by the same designer. He'll get a mic and some other details before he takes his seat full time.




I've been avoiding the instrument panel, hoping someone better than I can take on that task.

Thanks for replying, I figured it out. I had to trim the throttle down and everything started to work fine.

As I've always said, sometimes you can leave the trim alone and sometimes you can't. Lowering the trim to the bottom is one of the first things I do after setting up a new model. It's such a simple thing, I do it to all my planes UNLESS the manual says not to (some Eflite planes need to see a little throttle trim to bind in particular modes).

yf22raptor,congrats on the maiden and thank you for the PM. Parts ordered.

I tookoff and made a right turn to the downwind led. Abeam of the takeoff point it started a roll to the left, I applied right ailerons to correct with no response from the ailerons. Telemetry showed no loss of signal and no holds. It went in at full power in a nose down attitude. Power was killed just prior to impact with the throttle cut.

Had you gotten to the point of programming the Receiver? From what I understand you fly the plane with the AR637T first and get it trimmed then go for the AS3X programming and SAFE if you want to. I only ask because I’m going to use the same receiver and am a bit nervous now. It almost sounds like your plane was told to roll left and the correction you made was ignored. If you haven’t you ought to post this on the RC Groups AR637T forum. Andy from Horizon monitors it and may have some insight.

Try tweaking the end point on the throttle channel. Had the same issue and tweaked lower lower limits to like -102 and both initialized. I pulled it all apart troubleshooting before I figured that one out.

Yes there is a 2-3mm gap and the pin on the latch is about the same so any bump and it comes unlatched.

I put a 1/16" piece of balsa behind the striker plate and a small piece of one sided foam tape at the front (this made the gap the same front and back. Then I pulled the latch out of the wing, disassembled it and made the pin in the latch 2mm longer and dremeled the inside so the "T" could slide an extra mm forward. Won't come out next time! My canopy is a little heavier and valuable with the FPV rig but that is offset by the removal of the front pilot figure.

Plus one on the canopy hatch latch being totally inadequate, even with the halfway-point magnets. The pin is far too short and the gap changes as the hatch is shifted fore/aft, or the fuselage flexes. My father made the first two flights "stock", making especially sure the pin was engaged, but I pretty much insisted he add magnets at the rear of the hatch before he flew again the next day. I'm sure most of us have had at least one canopy/hatch come off in flight -- some planes hardly notice, while others become almost unflyable, like when the canopy flew off of my FMS 1500mm A-10. That was a wild ride.

[Evan D]

And it passed a range check? I assume you had the control surfaces all going through the BB? I don’t think that would cause loss of all control and then having it back post crash but it could...

Post crash control check did not have any problems with the primary surfaces. Other than the ailerons and rudders were distroyed

I just purchased a Fliteline OV10a bronco. I attached one motor and ESC to my receiver along with the BEC. One motor runs. However, the other motor will not run. I have the throttle in the correct position on both an AR610 receiver and a AR637T receiver. For testing I plugged the BEC into Aux1 as well as the bind plug socket. I've tested with both an Ix12 and a DX9. Both are bound. It was an effort to get the bind to start. Does anyone have any ideas? Sounds like the ESC is bad. When connected to the receiver, the receiver bound light is not on and there are no beeps counting the cells in the battery. IT's just dead. I also noticed the motors will not turn easily unless they are connected to the battery. Once connected they spin easily by hand. Which is confusing for me since I could see the one that works needing a signal from the ESC so I assume something is getting through the suspected bad ESC. Any ideas?

I have the same mix and it does help. Congrats!

Had a successful maiden today and 4 extra flights on her using hrb 4s 5000 7 minutes still with 60% left on the batteries wow ....prob go 10 min no problem..
using the new ar620 receiver and Dx-20 radio
no issues We did add rudder trim to Ail mix 20% rudd and really helps her in the turns ..

[Evan D]

KC, can you tell us what happened?

OV10 Bronco Crashes.
tonight I had a Second crash with My New OV10. Radio range test was Perfect and CG was on the money. I had a similar situation last week that I initially thought was "Dumb Thumbs" on My part. That crash cost me a new main wing, center pod, nose and left gears and retract. 2 props and a canopy. Tonights is a Total loss. Radio is a Spectrum DX8G2 and an AR637T reciever. As3x and safe were Off. Batteries used were Spectrum 4 cell 5000 MAH hard side Smart packe (2). Any ideas would be a Big help. I am sending the TX in to have it tested.
Alpha I attempted to send this to You off this page but You have too many messages.

I’m really sorry that happened to you and now I’m nervous. I have a Spektrum Ix12 transmitter and just bought a AR637T for my receiver and they are not cheap.

There’s already two good magnets, the latch and alignment is the problem. I’ve fixed mine, letting others know there’s a problem.

The canopy seated in the fuselage there’s a 2-3mm gap in the back where the latch is. The latch pin is about 3mm. Any flex and it pops.

[Mad Baron]

Add a magnet under the canopy that should help hold it down.

[Evan D]

Thank you.


I want to say the canopy latch on mine is barely holding. Came loose first flight.

[crash60]

Thanks again Evan D. Your OV-10 is beautiful.
