1. My original AeroAces motors would run forever(?) when the TX was shut off with the throttle advanced like would happen when the model got out of range of the transmitter. The one I got this month (Jan) shuts down after a sec or so when I do the same test. (You are the first person to confirm that this was just not a fluke on my plane.)

I assume that they made a change in the circuitry (or command program). Several of us had emailed the factory with suggested changes though it is hard to believe a change could have been made that fast.

2. The Lipo battery in the plane is protected from being overdischarged by a low voltage controller which shuts the motors off when the voltage reaches a preset level.

sounds good, thanks hoppy. i guess these ones must be updated. i wonder what modifications are coming(talked about here in last post link) if the auto shut off has already been adressed?
edit:
hmm i tested it when i first got it and the motors shut off when the reciver was shut off. now the next day (flight right after i posted) it is definatly not shutting down and flew out of control. its either a matter off fresh batterys, fresh plane, or i was plain mistaken yesterday. i can try fresh batterys when its charged next so ill edit again with the findings.
2edit:
fresh tx batterys and the plane continues to run with the tx turned off. kind of a straight forward test i ran when it was first out of the box... weird that i would either be confused or that the circuit would start now behaving differntly after a day of running in the cold and snow(shouldnt make a difference either).

Ah, so the question is still on the table. How about some more testers? Especially from AA's bought recently.

1. - Secure plane to table
2. - Advance throttle to 1/2 or there abouts.
3. - Turn off Tx with throttle in the same position it was in step 2.
4. - Do motors stop in a few seconds or do they continue to run?

I just swapped the original motors on a monoplane for 10ohm motors. These are longer and heavier but since I glued them on directly the net result is that the AUW stays the same. It's been raining so I could only do a test flight across the room but it was obvious that it still has the power to climb at full throttle. The motors consume less amps so flight times should be better.

after having my xtwins for 5 months, and using them almost every day, and having built numerous planes for them, i finally broke one of my RXs. i'm not sure what happened, i had the RX in my G-38 and it was flying fine two days ago, but today i tried putting it in my new tandem wing plane and it wasnt workin so well. for whatever reason, when i plug the battery into the RX, one of the motors spins slowly on its own, even if the TX is off. i unsodered everything and gave it a good looking at under a light and magnifyer, but everything looks fine. fortunately, i have a 2nd one thats still working fine.

anyway, here's the tandem wing plane i made today for the xtwin electronics. 6" wings, 2" chord, AUW of 12 grams. CG was tricky to get right, but its flying nicely now, and a lot slower than i was expecting. i think Plantracos butterfly airframe and electronics would make for a really nice (and incredibly slow) tandem wing plane.

You may have plugged in the battery in the wrong orientation.... I know what that does to an RX and your symptoms sounds similar!

That sounds like it to me too.

The earlier fighter jet that I make for the x-twin electronics was a tad on the heavy side. I was not able to get the lift that I wanted, hence I have carded it aside.

That's when I decided to built a QJ similar to Prasadl. The wingspan is 14" and AUW is 16.2g using balsa fuse and foam plates, but without wheels. Paint work was applied using brush and hobby paint (glossy finish).

It flew great, CG was spot on upon installation, and it cruises at low speed, and can handle light wind too due to its robust and slightly heavier frame as compared to my renolds wrap x-twin butterfly. It will definitely not fly away with the wind!

Here's the pics:-

Pete, i thought about that too. but, i've accidently plugged the battery in backwards a number of times over the months (shame on me for not using the polarized plugs!). the times in the past when i did that, it did the same thing, but after plugging it in the right way, it worked fine. maybe i did it one too many times.

Bill, whos email address?

Look at this photo my brother took when I was flying my x-twin in the garden.

moving battery forward DID NOT work for me. My plane would just fall on lowest setting and it required 1/2 throttle to stay up. Losing lots of air in turns.
When I got it stock Biplane or Single mod It would Gain altitude on lowest setting. Flew Like it had helium in it.! When Battery was in stock location I always had it in the lowest throttle setting and with just a little wind It would just stay in one spot, like a harrier jet. Going up & down . Somtimes I could walk under it And even walk faster then it. Its real cool when you get the PerfecT wind and get the Little Aero Ace to fly 2 feet above your head for 5 min!! Going left and right to correct wind gusts. Its not till you start making your own air frame that you fall in love with the Original super super light and snow resistant OEM one.

Can I get some help with the Proper way / Proper type OIL to use on these brushless motors.? Is there a difference in oil i should use between Brushed motors and our AA brushless/coreless ones?? I got one motor that stops 3 seconds before the other. Maybee I should take it apart and lube it up??
