Randy Lewis's turbo charged 12A one rotor.
Handy in the Alps.

Thanks Randy,

I will consider the Turbo version, my problem is the weight I would like to not exceed the weight of a Rotax 612 100 Hp, my idea was to have something very compact and very light someone told me about the Mid-West Walken Engine AE 110 Hawk but it seems that the Bombardier / Rotax have over the company.....the result is that we have only the 4 Cylinder Rotax and bye bye the Walken compact and powerful engine.

How much will be the weigh of a complete avio 12A engine ? ...maybe using different gearbox ? At the end I think that I will prepare the engine in CA and when ready send to Italy from there. In US you have much much practical knowledge applied to aviation engines that here in Italy.


for Paul

I am born in Latina close to Rome, but I am living North Italy. Somma Lombardo (Varese) around Maggiore Lake. When you will arrive in Italy you have 3 chance one is Rome, second Milan the other is Pisa I guess with Delta Airlines.

My brother is in LA in the next 1/2 week, maybe I will jump on a plane in few days and came to you, I need to see and understand to evaluate all possible options.

You can save about 14Kg by buying aluminum end housings from Racing Beat.

Quite expensive at about $1500 each. You will need two. A turbo is about
5 Kg but it saves the weight of a muffler which would;d be almost as heavy.
The other advantage is it does not stick out into the air stream and cause drag.
