HI GUYS
LAST WEEK I HAD SEEN THAT SOME GUYS ARE BUILDING PRETTY COOL RC AIRPLANES FROM WEAD EATER AND CHAIN SAW ENGINES AND THE I HAVE DECIDED TO BUILD ONE LIKE THIS

BUT I WANT TO MAKE IT A BIT MORE POWERFULL AND INSTEAD OF A 25 CC ENGINE I WANT TO USE AN ENGINE AROUND 38CC TO 5OCC AND IF YOU GUYS HAVE BUILD ONE LIKE THIS SO PLEASE SUGGEST ME THAT WHAT IS A BETTER ENGINE FOR THIS PURPOSE

What chainsaw engines have are you able to get?

Burelli used to use a Polan 46cc chain saw motor...
I saw one NEW 46cc Polan chain saw for $114 USD...
It is a beam mounted motor with GOOD power...
I own one and have been quite happy with it....

GOOD LUCK whatever you wind up with...

You really need to tell us more before anyone can advise you. What experience do you have flying model planes? What kind of site do you fly from? What do you wish to do with this model? Sport flying? Carrying cameras, etc? This is an unusually large model for beginners.
