Hi,

I bought my TT-75s in England for 129 Pound.

I use an APC 12x7 or 12x8 depending on flying style. This engine wants to rev.

After break in, I checked the engine and found the camshaft sintered bearings "wet". So, I do not see a need for any modifications.

Actually, I am disapointed about the engine because of these sintered bearings. It´s a very cheap solution. I expected ball bearings. Anyway.
