Go with the 46. My uncle recently bought this plane and put a gms 61 in it. The plane came out rather nose heavy resulting in quite abit of extra lead having to be put in the back. He had a few problems with the engine and encounted a few dead stick landings. Well the glide distance for this thing was not much at all. I really came to understand the term flying brick after watching this thing with no power.

Change the motor to a Mag 52 and did a bit of lightening. No pilot, cut out the wells in the canopy,slimline pitts, aluminium backed plastic spinner, wood prop, 1100mah 4.8V battery,no wheel pants, light foam dubro wheels and of course the lead that was once needed to balance. This thing has been totaly transformed with this weigth reduction. On deadsticks it now glides great with it having to slow right down before dropping a wing. The overall flying of the plane has also been able to be slowed down. Also may help those carbon gear to last longer.

Other areas of weight we were going to look at was a carbon fibre wing tube from PBG composite, I think it would have nearly saved another 30grams as well as a 6V AAA NiMH pack saving around 35grams. A mini servo for the throttle is another easy way of shaving off another 24grams
