K&B for Graupner F1 tunnel

Hi all
Im new to this fast electricery thing and fancy the Graupner F1 tunnel, Ive heard that the K&B lower leg is a good starting point.
The thing is should I go for the 3.5 or 7.5 unit on above hull.
Any advise on K&B unit and hull choice would be most helpfull.

I'm not positive, but I think the vast majority (or all) electric guys run the 3.5cc lower unit.

thats correct, the 3.5 lower leg is the one to go for, you'll notice the graupner f1 hull comes with a IC enegine and has the 3.5 leg on it
