Thanks Ron. Each time I experienced the issue it would get to the top
and corkscrew to the right. And, yes, after that it lost lift. It
should have tracked straight and true though. I don't have that problem
with my YAK-54 - it tracks nice and level at all times - at least for
me so far. But I haven't flown it a lot. I have encountered that
issue with my GWS F4U Corsair. But I quickly learned it was because I
was mounting a 808 keychain camera out on a wing. That made one wing a
bit heavy and it would tend to corkscrew in a loop. I don't run a
camera on that plane anymore but did have to tape a little weight on a
wing to get it to balance out. Now it tracks nicely. But it's a LOT
easier repairing foam than these built-up wood planes. ha ha..
This is the motor I was running. I'm sure glad it survived because it
took the brunt of the crash. And the rare earth magnets have really
taken a jump in cost lately so these brushless motors have really spiked
It's 220 watts max. I checked it with a wattmeter on my setup and it
was pulling 190 watts full throttle. It had plenty of power as I never
flew it more than 1/2 throttle on the whole flight. So if it required
more power it was pilot error - not the setup I think. The problem was
that once it went off-level the wings started losing lift (stall - like
you said.) And I wasn't a good enough pilot to correct it with left
aileron in time to keep it from spiraling in. I still think it's a
issue with the design - maybe in the airfoil itself. It should NOT
have done any twisting (roll) without me giving it left/right aileron. It
should have stayed level.
One thing I did do wrong however was try that loop too low. I should
have taken it up a lot more. Then I would have had more time to
recover. The old adage "altitude is your friend!" Regardless, if it
was that finicky I really wouldn't want it anyway. It's not fun to have
an airplane that is so touchy you constantly have to worry about it
acting up and having to correct for it.
All part of the hobby. Without the risk of crashing there would be no
challenge in flying these things. And with each crash you (hopefully)
learn a bit more. Live & Learn!
Thanks for the input.... I appreciate it.
