List of convertible engines
 

Hi guys!
I think it would be a good thing if we made a list with the engines we have converted, see this example (not real data):

ENGINE: 40cc Homie (how big the engine is)
ORIGIN: Homelite 240 chainsaw (where it came from)
WEIGHT (converted): 2.4kg
RPM: 7200 (20x8 prop) (indicate prop used)
THRUST: 9kg (if you can manage to measure it, indicate prop used)
CONV. LEVEL: 6 (being 1 the easiest to convert and 10 !QUOT!you'd better look for another engine!QUOT!, I think this will help when purchasing an engine).
NOTES: crankshaft sticks out of both sides (to put any comment you find useful).


In my very short experience, I've found that string trimmer engines would have a lower conv. level (that is, they're much easier to convert) than leaf blowers or chainsaws, in this order.
Well, it's just an idea :eek:

In that case I´m with the poulan 46cc at 1.8 kg. chech it out at www.tntmodels.com.ar
my first choice is a 31 cc Ryobi at 1.400 kg. with engine mount and custom made muffler.

Boy, I've got too many to list out in detail like you did. I would have to disagree with your saying that trimmers are easier than chainsaws and blower. My expeirences are the opposite. Chainsaw ans blowers are typically designed to run full throttle most of the time, so they usually come with a bigger carb. Trimmer OEM carbs have tiny venturis and so need replacement or mods.

As for having to cut extraneous appendages off the crankcase, trimmers and blowers can be just as bad. Smaller chainsaws are typically much better in this regard - open up the plastic cases and a read-to-use short block practically falls in your hands. :) Big chainsaws likely have the engine crankcase cast as part of the case and need more work.
