I am interested in converting a chainsaw into a airplane engine. The poulan 46cc is very tempting, however, the Echo 44cc seems even better for a little more upfront cash. My question... has anyone converted one of these and if so... does the stock echo computerized ignition have variable timing like a C&H Synchro-spark and is it suitable for aircraft use? Thanks.

someone's gotta know this....im curious as well.

Got some people looking into this also. In the past Echo would not sanction using thier engines to power any type RC due to the liability of "remote" -ly striking someone or something.

I don't know of anyone who has adapted this engine to fly. However, I do know there is a place in Ohio that buys Echo twin cylinder engine parts and machines a crankcase and all the parts needed to fly. If you want I can get the name for you. He's sold quite a few of the twins.

Technically the CS-4400 (the only way to get the engine is to get the entire chainsaw too) is a top quality engine:

1. Ball bearing supported and counter-balanced crank
2. SAIS or "Slope Advanced Ignition Spark" which means the spark will automatically advance as RPM's go up and visa-versa.
3. There is a Canadian version which meets Canadian radio interference regulations.

My dad works at Echo Incorporated. I don't know what he is doing now, couple months ago he was still redoing all of the repair manuals. The above is a quote from an e-mail I recieved from him.
If he can find out any more I'll let you guys know.

It is my understanding that the BME 44, 2.7 cid engine is an Echo 44cc engine.
