How does it fly using a tower .75? What prop are people using with the tower engine? Will it be comparable to the GMS engine? Will I be ok using the stock muffler or should I upgrade it? If so, which one? Sorry for all the questions, I just don't want to buy the wrong equiment.
With either the Tower or the GMS and the Graupner 11x8P prop, this is a speedy bird especially with retracts.
It flies great.
IMHO you do not need to do a thing with the muffler.
The only thing I had to do was to adjust the C.G. by moving the 1200mAh 6V battery pack I'm using to the nose.
If needed I had planed on putting a second one up front, but I did not have any need to do so.
