RE: CMP Edge 540 T 50cc Balancing info
You're right.
I flew mine at the second tick mark, and it was too tail heavy. I brought it down ASAP, lest the diminishing fuel make the plane unflyable!
However I now fly mine with the C.G. set about 1/4" in front of the first tick mark and I find this perfect.
It will fly either upright or inverted with NO elevator input, but does not feel tail heavy when the tank is empty.
It hovers pretty well too.
Once the C.G. is dialed in, it's a sweet flyer.
Mine came in under the advertized weight by about 1/2 lb.
