VQ models AT-6 Texan

Located this ARF at sensible price to utilise existing hardware. Ordered the Miracle scale type spinner from China. Despite using a much heavier motor than recommended it would have still required significant lead in the nose so i rebuilt the bulkhead and motor mount to create a 30deg sloping box to shift the C of G and eliminate ballast.
Just waiting for a new Rx and some suitable test flight conditions.

I would highly reccomend strengthening the wing hold-down plate and maybe glassing it to the fus' side walls.

The wing plate seemed OK but nevertheless followed your advise and reinforced with epoxy and small glass bandage.

Also
1. with 4 servos and 2 retracts to connect I used these 8 way MPX style connectors for Port & Std wings sides respectively.
2. Unsure about the impact of an electronic retract overload on the Rx supply so just taken the retract signal / common wires to the wing and fitted a dedicated 2 cell Li-Fe on the wing. (also because they cannot use HV)

Good move. I was going to suggest that. Just needs a signal and common. You might find you need to connect your Life common to a common point on RX side.

Yes the battery common is linked to Rx common - the mini 300mA battery has performed approx 20 cycles and still has > 50% charge.

I have just splashed out on some MPX connectors too for my H9 Twin Otter due to the fact of some many wires in and out of the wings. (and after a while I forget which JR plugs go where even though I built the wiring :lol: ) Pity they don't seem to make right angle brackets though. The small PC boards give the advantage of more security when pulling the plug on and off.

MPX odd number of 8 pins. Although, 2 x 3 pins for ail and flap and two for throttle = 8

Looks like you have glued the sockets to wing?

it suited my installation to have then flat against the wing to prevent fouling anything in the fuselage and it makes connection easy.

3 pins for ail servo
3 for Flap servo
2 for U/C signal and common - power from on wing battery. - in your case case signal and common from ESC if you are using Rx battery

However - There is a device to allow sharing dual esc power to RX but not cheap

This is how i know abot vq weak wing plates..

was that a pre flight or in- light failure

The two VQ warbirds I have owned (a mig.3 and the yak.9) had an extreme tendency to nose over on taxiing and take-off which requires full elevator to counter - this often leads to ground-loops and subsequent wing tip grounding which rips out the wing mounting plate. Hope yours fares better!
