Lupo tip
I purchased a Multiplex Lupo for a couple of months ago.
The first flight almost ended with a crash since the plane was much to heavy at the back. I moved the engine forward and managed to get the CG where it should be. The next flights went OK but I thought that it behaved a little strange in the air when changing motor speed, but I settled with that for the moment.
But when I then tried to fly it indoors, where there are no room for strange behaving models, it was very hard to control.
when decreasing motor speed the model lost hight very fast and when trying to compensate with the elevator it stalled very easy.
An other club member gave me a tip that I should raise the back of the wing a couple of millimeters. I put a bit of depron between the fuselage and the back of the wing, and at the next flight all the problems where gone
!! I didn´t thought that a small change like this could totally change the way a model behaved.
Anyone else out there with the same experience on Lupo or other models ?
