No luck.

I flew the Evo .60 powered plane and the engine did the same thing as the S/T .60. At home I took the tank out and it occurred to me that by using an R/C type engine mount it left the tank compartment open and susceptible to vibration. I went about installing a 1/4 inch balsa floor in the tank compartment that will ace like the traditional hard wood motor mount we normally use. I had the same thing happen to another plane and the extra wood fixed the problem. The rain has kept me from testing the fix.
