Got a plane that calls for a Zenoah G-62 (Ziroli Stuka). Is there an engine available that is in the this displacement for conversion. I've done one weedeater, Mac, which made a nice engine. Thanks, Bill S.

Hello wsmalley,
The engines that come to mind in the 60cc (4ci) catagory are, Husqvarna, Stihl, Sachs-Dolmar. Here is a nice Stihl 038 CDI conversion. With most of these big saw engines you have to trim away the oil and gas tanks from the saw chasis. Much care is required, so as not to damage the crankcase. Here is a nice Sachs 3.7ci saw conversion in RCU. Enjoy.

Poulan (craftsman) makes some saws in the 50--60cc range.

I've done 2 of the Poulan 54cc engines. Good power. You do have to cut the gas and oil tanks away, and then dremel it smooth. But, it's not hard--just a little time involved.

Are you interested in a 62cc Pioneer engine? Side reed induction. (Think 3W-70.) Already cut it apart--you just need to finish converting it. Replace bearings, seals, and get an ignition for it.

Email or PM me if your interested.

Dude, that is a sweet setup for advance/retard on the second pic, Dave! Attached to the throttle, very cool.

Hi Doc,
That is someone elses engine. I just posted it as an example, since it is in the public domain now.

There is no shortage of engines to convert out there. The husky engines come to mind as good candidates as well as sachs. One really needs a chain saw book to know how big the saws are as model numbers do not always mean size. And thanks for thinking outside the weed whipper box.

I converted a 62cc Zenoah blower motor. Great engine with comparable power and weight to the RC version. Still have it sitting around... just couldn't find a suitable airplane for it. I got way too many engines anyhow.

I converted a 55cc Homelite out of a 330 model chainsaw with good results. You will have to cut part of the engine away with a good band saw though. Whats funny is that I sold the parts for more than the chainsaw cost in the first place. Its a reed motor, so the carb will stick out at an odd angle. It turned a 22x10 prop 6800 rpm, which is the same reading I got with my G-62. I will probably run a 20x10, however, it turns 7600 rpm. I bought a new big bore carb, everything else was fabricated. Cost including carb (minus the "profit" from the carcass) 30 bucks.
