Thanks for the advice.
I do have an Eflite 480 I can use. I was just wondering if a Power 10 had been used before.
I saw a couple of other postings on RCGroups.com where they had used 450 - 500W systems and had problems with wings folding, elevators cracking, etc.
They also did not recommend higher than the 480.
Again, thanks for quick response.
