I read story after story about issues people have with TT setups on other brands. One time, with my E7SE, I broke the tail fin and rear landing gear struts in a really hard "landing". Before I hit throttle hold, it proceeded to grind my tail blades down to stubs on the asphalt. Zero damage to any of the gears in the TT drive train, both front and back. The only other TT setups I have any experience with were the Blade 130X and 180CFX. The TT setup on both of those made me want to smash them with a hammer.
