Revmaster 2100D install

Postby Sonex1243 » Sun Jan 15, 2017 4:58 pm

Has anyone installed a Revmaster 2100D engine in the Sonex. Initial verification calls to the manufacturer indicated a good history of the engine by S/N, no major refinements needed other than an ignition / intake manifold upgrade and adapter kit for aerovee mount from the original Sonerai IIL setup. This is a brand new (dry storage) never run engine complete from Revmaster. They also indicated that the engine is 75 / 80 HP and should fly the Sonex. Any thoughts / experiences would be appreciated.

Yes they have been used successfully on the Sonex, here's one example that comes to mind:

There are quite a few others.

I understand power will be pretty much identical to the standard AeroVee, they just rate their engines slightly differently hence AeroVee claims 80hp where GP and RevMaster claim 75hp for the same engine size.

One thing to note though, the bolt pattern on the RevMaster is different from the one on the AeroVee, GP and Hummel, make sure you keep that in mind when ordering your prop.

Thanks Michael, great information on the links you suggested. The engine comes with the prop, however, this is a tricky decision for me. The engine comes with a Sonerai IIL single seat build (easily converted back to 2 seat) that is well over 60% finished. It was an estate that was donated to the local EAA chapter which is being sold at a very reasonable price. The workmanship is unbelievable, one would hate to break the kit up.
