A 3-blade would solve the clearance issue!
Do you have any pictures of your set up? The smaller size might be a nice thing.
I really wish I could find the weight of the various engines with all the support equipment. It seems pointless to use a 40cc engine when there are 50cc engines that are similar in size, quite a bit more powerful and that weigh less. Well, according to the manufacturers they weigh less. I mean, what if BME actually releases their Xtreme 55cc? Jeez. [sm=confused.gif]
Good thing I'm not in any hurry. I have plenty of time to pick an engine. Maybe the ZDZ 40RE F3A will be released and it will be superlight or something.
If I would have had the money I would have just gotten a 40%, bought a bigass 200cc twin and been done with it. I really need to hurry up and get my MD.
