Love to see a 3S one in around 1.3m with flaps and a 2-2.2m one for 6S with all the toys (flaps, retracts). Maybe make one of those a Turbo Commander to cover a few bases. Got a chance to see a couple Turbo Commanders operating last month when they were bird dogging a couple fires.

Same price as the A-10. It probably uses the same board.

What's the story on the paint scheme, is it based on a real plane or just for visibility?

It does.

Hopefully many more UMX twins to come!

Are the motors/esc's on a single channel or could they be setup for thrust vectoring (or whatever it's called)

I am sure they are both on the throttle channel only.

Ten Minutes on a 450mAH Battery?


That is according to the Horizon Hobby site -- up to 10 minutes on a 2S 450mAH battery. Is that realistic? I'm hard pressed to get more than 7 minutes on my UMX Timber using a Nano-Tech 450mAH flying mostly low and slow. And that gives me a reading of 7.6 volts 30 seconds after landing.

Might do a Turbo conversion on this. The bird dogs used the same hanger that my flying school used, so it was really neat to see them up close.

They are most definitely on a single channel, as none of the conventional fixed-wing UMX bricks have dual-channel ESCs, nor do they support reverse thrust. To have differential thrust, you'd have to reprogram the brick for full 6-channel operation (they're factory-programmed for reversed CH2 on the AUX port), put a Y on the ailerons, install external ESCs on CH5 & 6, connect the motors to their respective ESCs, and then program your transmitter accordingly.

Voltage is not a reliable indicator of discharge-depth. The only true measurement is how many mAh it takes to recharge. Also - flying to a rest voltage of 3.8V/cell is only ~50% discharged. The rule for LiPos is to not discharge them deeper than 80% - as measured by mAh required to recharge, divided by pack capacity. With a 450 mAh pack, 360 mAh required to recharge would be an 80% discharge.

Given the above - you're using ~32.14 mAh/minute while flying mostly low & slow with the UMX Timber. 360/32.14=11.2

So, that would be ~11.2 minutes to the actual 80% discharge point with a 450 mAh pack.

Have you tried flying for an additional 2 minutes and then check the resting voltage (after 30 seconds)? If so what was it?

Has anyone (probably in the A-10) flown 3S on this board?

I have a bunch of 3S 500s. I'm wondering how hilarious that would be. Probably just hilarious enough to blow the blue smoke out..

I doubt anyone would fly 3S on the A-10, but this Commander is a simple matter of just re-propping , or swapping motor like everyone does in all the other UMX planes that routinely get the 3S overhaul. I think its the 2450kv motor swap, and or people prop down.

I haven’t because the fans are much more unforgiving than the props.... plus the umx inrunner motors can’t take 3S.

But they should be the same escs as the rest, all of which do pretty good with 3S...
