RE: 100cc engine choices
You cannot go wrong with any set up you get from Jim Short!!! I recently got one from those guys, and WHAT A DREAM!!!! I did the covering on it and installed everything in it in about 80 hours!!
As far as weight considerations, I don't even consider the Carden's being heavy!!!! Who cares what the actual weight of the plane is!!! I dont!!!! Just as long as it flies LIGHT!!! I'll tell you this........ My 35% 330S probably weighs 30#, but gauranteed it flies like it weighs 20!!!! If you want to see pics of it, please feel free to email me, or I'll post them here!!!
PS- putting cans in the Extra, SIMPLE!!!! Very easy!!!
Enjoy!!!
