[rede2fly]

hey bomber are you there?? got a problem with a motor??

[bomberbill]

thanks for the reply. I have a 49cc gas engine I want to convert. It ia from a motor scooter. Is it worth it to try to convert it or should I look into a dl50. The engine I have does need a custom prop hub. I also need to know If I can build my own electronic egnition. I am one of those guys that want to say I did it all myself.

Thanks for your help

just get a da50- you would find the engine you convert would be too heavy etc and a lot of work.

Correction ... get a "DL-50" .... Half the cost and better performance than DA50.

Sure you can build your own ignition but the parts will cost more then a ready built and tested ignition with a Warranty.

buy the 50 use all that free time on set up and trimming

Better yet, buy my Venom 45. It is cheaper, powerful and comes with a FREE 3.75" spinner and a 20-10 prop.

It is in the swapshop here on FG, check it out.

There is only one 50cc weedie.chanisaw engine that I would consider converting, that being the Echo 50cc chainsaw shorblock, Part Number SB1080 available from several Echo parts suppliers for about $210 USD or so, as a complete unit.

To this you will need a WT503 carburetor (about $35), spacer block (homemade) crankshaft extension (about $25 from a machine shop) and the miscellaneous nuts and bolts to get thigns going. . about another $10 or so.

Total, sans ignition, of about $270, and weighing in at about 3 lbs even without the exhaust. J&A makes a Pitts style exhaust for the engine, if you want to contact them, it costs about $50, and an off the shelf RcXcel ignition from CH will run you about $75 plus shipping.

So, for a total of about $400 you have the entire engine, muffler (very good piece) and ignition.

The engine comes with a Beam style mount, like a glo engine and is within 200 rpm of a DA-50 without modifying it in any way. Again, it weighs about 3 lbs 6 ounces WITH ignition and muffler, the same as the DA-50, and power is within 200 rpm, and sometimes the same, as that engine.

For reference, the Echo engine was once distributed by BME Engines as the BME-50, and many of them are out there in aircraft right now, flying around and doing just fine.
