I have a Direct connection f20. If you want to talk about speed, I have installed a YS 61 with pipe using an 11 x 11 apc prop, retracts and a shute. Man does this thing go. I estimate 140 - 150 mph.
cool. I have a mag 52 in mine right now. I am thinking of building another one over the winter. probably use the 52 until my nerves can handle something more balistic.
