Sounds to me like you need one of the servo reversing tools available from HH. You can selectively reverse either servo to get it going in the desired direction. If they work at all the servos are probably ok and one of them just needs reversing.

Thanks, that should do it. I guess I need to order another plane--wouldn't want to waste shipping charges on just a cord. At least I've learned how the plane is put together and where everything is.

I've got my throttle-timer set for 13 minutes, and I never hit the 80% discharge point with the Hyp 550. Of course, this is highly dependent upon one's flying style & use of throttle-management. I modulate the throttle as the situation dictates, and tend to use WOT only when a maneuver requires it.

Unfortunately, it's been long enough since I last flew the plane that I can't remember if I had the timer set for regular flying or carrying a keychain cam last time around.

That makes me think that the servo is the problem, if the problem changes to the new output...

I tried to reverse the servos using the throttle and aileron controls but I can configure both moving together in same direction. Any other command turns off the servo with the wing hit.

Did you manage to set the Rx up for dual aileron? This needs to be done on the Tx & Rx.

I tried reversing the servos on the aileron option in the radio but it just changes the ailerons from up together to down together.

I guess the next step is buy a replacement servo to get the micro thingy to reverse the servo? Can you buy the reverse connector without buying the servo?

thanks

Lynn
Hope this helps

Hi All

I had two flights the last two days, finally the wind dropped.

Now that I have the CG worked out and she is no longer tail heavy, she is a joy to fly. I flew at around 7am this morning with the sun coming up, had to really concentrate as orientation could become a massive problem i think.

Did some nice loops, stall turns, immelmans and a few practice landings on the cricket pitch, had one decent landing and a few nose overs unfortunately but nothing serious as I was coming in really slow.

Thinking of getting the UM Spit Will have to convince the wife that its a matter of life or death

Great idea! Although she is going to have to learn to fly the mossie then!

Got the servo reversed and tried to fly it again. There was more wind than I realized but got it down. A wind gust flipped it before I could grab it and clipped the back of the fusilage on a metal fence posts.

Not going to reglue. Parts are on classified: http://www.rcgroups.com/forums/showthread.php?t=1764292

Thanks for all the help.

Nobby33,
Here are my UM Spitfire and Mosquito on a recent flying day, together on the tailgate of my Element.

Cheers!

Maiden flight

Bought a Mosquito second hand. Pretty good shape. Both motors run fine.

Maidened her today in moderate wind.

Former owner flew her with almost all the way down trim. However this was not much a CoG issue. The elevator needed to be mechanically trimmed. Once it is levelled you only need two or three clicks on the radio.

She is not tailheavy but on maiden I should have pushed the battery a little bit forward. I have balanced her on theoretical CoG, 38 mm from leading edge but I think 36 or 37 would be more appropriate when the atmosphere is not completely calm.

Since I am not an experienced flyer I was somewhat stressed during the flight but fortunately everything was fine. Takeoff was handlaunched and she was landed on grass.

I wish i could practise touch and go's but I feel I need some more practice before that.

I am very interested in setting up differential since I use a DX6i. Will do that at a later stage.

Last point: she put such a smile on your face that I suggest reimbursement by the social security.

Using differential ailerons and deflecting the "spoilers" up for slow flight really makes the mossy much easier to land, without the tendency to tip stall.

2nd flight

Flew her again this week end in very windy conditions. 10 knts established and 18 kts gusts. She flew quite steadily most of the time but I was unable to recover her after being completely bounced by some gusts.

Since I was flying quite low in order to avoid more important turbulences above 50 feet every lost of control resulted in non desired landing (grass fortunately).

I need a little less air...
I need more agile thumbs...
I need more time...
I need AS3X... Not so much in fact. I am intellectually happy to fly "natural". At least as long as I do not experience a major crash.
