Does your Spitfire always stall to the right? Mine does - and I am wondering why....

[PilotAndy1994]

So I recently revived my Dynam Spitfire after it sat for almost 2 years in my room after the ESC burned up causing a little ding which bent the motor shaft. I put a new shaft in and put E-flite electronics in her, and threw away those AWFUL retracts!!!!

She is a belly lander now, but there is something I am noticing about this bird that perplexes me, and maybe could offer some good discussion.

when flying with either the motor turning or stationary, she always - always drops the right wing in a full up turn, or a stall - why?

There is no pre set in the rudder that I can tell, although the right wing on mine does have a little "Dynam twist" to it.....Maybe that wing has less area generating lift due to the curve, and thus stalls out first?

I noticed the motor has some right trim to it, counteracting the torque as usual, and thought this is what caused the rightward stall on low power stalls - as the thrust is directed more to the right....

Even in a power off - steep left hand turn - she still snaps over to the right.

Wondering if anyone else has noticed this? Thought it would offer some good discussion.

Thanks,

You are giving it to much elevator, I limited mine to 80% and it has not since. My experience R.

Sorry for not clarifying that I was asking this as more of an aerodynamics question. I do aerobatics a lot with the spit, and it always snaps to the right. I thought maybe someone knew why this aerodynamically happens. When your in a left turn with no power, you would think with full up elevator the plane would enter a left spin.... It doesn't, rather entering a right spin! Can't figure out exactly why, though. .

its not uncommon for foam wings to pick up a warp while in storage. have you trimmed it out?

after setting the E and A for level flight, I like to do figure 8's to see if it favors one side or the other adjusting the rudder so that it tracks the same in L and R turns. normally you will see it track fine to one side and want to nose in on the other. I adjust till it goes the same amount in r and l turns before curling into the turn.

its a foamie so you really cant use a incidence meter to check the wing, you would have to set it on a flat surface and measure the distance from the surface to the LE and TE if the wing every 3 in down its span and you will find the warp.

yes the right wing has a Warp in it. I will try that measuring tip tonight. Thanks!
