I'm needing a set of doors for a 701, prefer the bubble ones. But I would consider the standard doors.Continue

Hand brake

This is my hand brake made with the original master cylinder that came with the kit. Tried black max, but not enough volume for both calipers. Now it will drag the tires.

Michael,
I purchased my 701 with a 670 rotax (built by rotax rick) already in it.
Things I like about the 670
Great power to weight ratio (92hp @ 100lbs)
Simple engine, less to go wrong, small size leaves plenty of room to work on it.
Initial cost and rebuilding is much cheaper than aviation engines.

Things I dont like
2 cycles have reputation for stopping suddenly with little or no warning. So far (120hrs) this has not been my experience, but something I think about and try to keep in mind.
Recommended TBO is less than other aviation motors, although still cheaper in the long run.
Have to add 2 cycle oil, on longer trips, you need to have it along with you.
You have to watch EGT very close, easy to get lean when descending (this is something I have gotten used to, not as much a problem if you are careful. )
The weedeater sound....very LOUD weedeater sound.
Also higher fuel consumption than 4 cycle.

Overall I would recommend the 670 rotax for the 701,
I do think it requires being more careful in operation, but a good choice.

If I were to have my choice in currently available engines, I think I would probably prefer a Viking, nearly the same price and 4 cycle, much quieter, parts easier and cheaper to find, much better fuel economy and still good power to weight ratio.

Hi, Micheal. I finished my 701 in 1997 and flew it for several years.  One day a guy came by the hanger and offered me a very good price so I sold it.  The only reason I sold it was it had a 2 stroke 2 cylinder Rotax and at the time I couldn’t afford a 912. I have since rebuilt a 701 that had a hard landing and helped finish another 701 when the builder became too sick to finish it.  Then got very busy working on airplanes doing repair and annuals.  I have finished rebuilding a 415C Ercoupe that is ready to fly now.  Will be flying it to Kingsley for breakfast this summer and would enjoy seeing your 701 sometime.
