I aggree, I have flown mine about 2 dozen times now and am more than happy with the TT46 Pro I fitted, so much so that I bought a brand new one after the first weekend out and fitted it in. After running in, I put on a APC 9 x 6 and the performance is fantastic.
I had a TT 61 Pro but to fit this would bring the wing loading up from 23 OZ to 29 OZ, I dont like trying to glide bricks if you get a dead stick, I am trying to work out how to lose some of the 5 OZ I have in the nose to make it lighter.
The possible solution arrived today, a brand new OS RSP pylon motor, lighter more HP and 24000 RPM, I am going to bring the header thru the fuse and mount the pipe underneath to better streamline the model as well as mold up some servo covers for the ailerons and rudder servos to cut down drag.
I would even like to build a balsa built up 2/3rds size and fit it up with a OS 21 marine motor (30000 RPM) and fit a wemotec 90 mm fan.
