Nitro planes has posted a review from a pilot that found out that the CG printed in the instructions is the CG for the 60 size the correct CG is 85mm from LE. That was the reason for the stall problem. I got the plane dirt cheap because my cousin flys Helis thought about getting into planeschanged his mind never even opened the box and gave me about $140 of brand new Hitec servos still in the boxes with the price tags on them. The plane is very well made and the paint job and water transfers are some of the best I've ever seen on a ARF. I ordered the retracts from AK models last night we'll see how they work. Out of almost 200 flights I've got 1 crash due to wing failure on a ARF that I didn't build and no hard landings. So I'm pretty optimistic about flying this P-40. I'll keep you guys posted on how it goes. I'm about 10hrs away from completing my P-38 with Davis Diesels so the P-40 is on hold for a while. Thanks for all the info much gratitude from SoCal.
