Lightest .40 - .50 size engine
Hi,
I'm looking for the absolute lightest 40-50 size motor. So far It looks like the webras are pretty light. I also need very linear throttle response. Right now I have a os 46fx on a "Madness" - it's a pretty good combo but I know theres better :-) I'm not looking at 4 strokes - just two strokes. Any ideas for the ideal motor?
thanks in advance,
Jon

OS 40 FP (and 40 & 46 LA) are the lightest ones. They weight close to typical 25 BB. However, more Madness you will something more powerfull -- perhaps the Webra.
I suggest you to take another look at Saito 72 and Ys 63. Both are lighter than most 46 BBs, put out more power and have hassle free and instant throttle response.

Lightest 40 - 50 motor
I agree that the Webra 50 is about the lightest with GREAT power transition curve. As far as the lightest 40 with great power, consider the HP 40. RJL offers the HP on the West Coast. It is extemely light, BB and great power & transition. Allot of people use the HP 40 in lieu of the Webra 32, OS 32, and TT36 on stick planes. If you want a 40 size motor, check out the HP 40, otherwise I'd go with the Webra 50 (I own 6 of them )

Motor
I just finished a Diablotin Super with a HP.40 all up flying weight is 59.4 oz with 935 sq in wing. The engine with header and mousse can muffler weighed 13.7 oz.. It's a good .40 motor in a .25 size package, but does not have the power of a .50 size motor. For my airplane I wanted extreme light weight. I had a ST.51 set up that weighed .45 oz more with more power, but weight matters. Tom
