Default Four Star 120 with Gas??

Looking for input from folks that have used Gas engines on their Four Star 120s. I would like to use a G23 or G26. How does it balance out with this engine? Did you need to shorten the nose or add weight to the tail or mount battery in the back?? All thoughts and ideas are appreciated.

There are several threads on rcu with more information than you could read in an evening on exactly what you are asking. I researched it last year for a buddy. FWIW his 120 did not fly very good with his Ryobi 31cc conversion .

I play with conversions and the ryobi to me is the worst. its underpowered and overweight. Homelites are the best balance of weight to power for an engine I cut off a weedeater. some people like the poulans and stihls but the homelites are just easier to get a hold of.


ps to the original poster. if you dont already have the zenoah i would consider going with a crrc 26cc gas engine. the thing has great power lighter weight than the zenoah. even the ei version of the g26 is still heavier than it.

and best of all its 199.99 cant beat it for price on anything.
