80 cc to 100cc conversion engines
 
hello

Are there any 80cc to 100cc conversion engines i am intrested in building a 37% extra but cant afford a DA or other expensive engines out of my budget.

Stihl makes a concrete saw--model 710. It's 110cc single and it's a BEAST. But, once you get it out of the saw, it's actually very light.

They get droppeed or run over by machinery. Engine is still good, but the saw will have a broken arm or the case is mangled beyond repair. I got mine for $50.

You'll have to cut the engine out. It's part of the saw housing, just like some of the chainsaw engines.

Would a single 110cc motor not vibrate the wings right off?

it will do some shakeing all right , the 100cc sachs would shack a lot, my guess is don't run the engine on the plane with the wings off it may sling the tailfeathers plum off.

hello Rcpilet

Can you post some of the pics of the engine , and which plane you used it on, is this engine is capable of doing good aerobatics.

I have operated the 82 and 96 cc Sachs engine (5.2 and 5.8) in a wood saw and the vibration is minimal, the 22 pound mass of the saw is a tiresome issue however, lot of effort for an amatuer woodsman. Believe Ralph C is very knowledgeable on vibration issues, ask him for a opinion. A husky 100 cc engine is also a good candidate.

I sold the engine to a friend who put it on a Lanier 35% Giles. Will it do areobatics? In a word ------ SICK
26-10 Menz at 6900RPM. 40:1 Husqvarna chainsaw oil.

It was a simple conversion. Cut the case away, just like some of the popular chainsaw engines. Buy a C&H ignition. Machine an aluminum hub. Cut the muffler open and gut it. Weld the muffler back together. Rebuild the carb. Get some aluminum stand-offs and bolt it to the firewall.

I don't have any pics of it. Sorry.

I was always told that was rule #1 on a gas plane.

NEVER run it without the wings attached. They act as a tremendous vibration dampener.

I saw a guy running a gas engine on a plane without the wings on. I told him a couple times that he was going to shake the airframe apart. He wouldn't listen. Thought I was an idiot--and the look in his eyes told it all.

About 2 minutes later--horizontal stab came flying off. Basically ruined the plane. If it was fixable at all--I'll bet it took 40 hours to rebuild it.

DUH!! Jackass!! [sm=lol.gif]

I laughed outloud as loud and hard as I could muster. MMMWWWWAAAAAAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!! TOLD YA!! MMMWWWAAAHAHAHAHAHAHAHAHA!!!!

I love watching arrogant A-Holes stick their foot down their own throat.
