RE: Low Down on the CMP P-40 40 size ??
The CG on the CMP P-40 listed in the instruction as 85mm for the leading edge , is wrong. I converted one to electric and found this out the hard way. I emailed raisen tech about this, and to this date no responce. I would not attempt to fly it without calculating the correct CG location, using a CG calculator.
Here's the thread that I made on it:

Go to the last pages, in there some one posted a link on a CG calculator program. See if you get the same results as I did. To date no one has verified my calculations, and I pretty much gave up on pursing it any further.
