I have a Modeltech Sukhoi SU-29 40 size. I'm looking for a 4-stroke for it. The instructions call for a Magnum 52. Does anyone have this model? and what is a good engine? My concern is wt.

I've just started on this ARF and am considering the RCV 58CD, Saito FA-82a or maybe buying the the new Saito FA-62 for this plane.

I own a Magnum 4-stroke, but have not run it yet. I hear they're not as powerful as other engines in the same class.

My main concern, since the plane is relatively light and should fly with a smaller engine, is fitting the engine inside the cowl without cutting most of it away. The supplied louvers, if opened should draw good airflow.

Update:

I have been flying my Modeltech 40 size SU-29 with the RCV-58CD and am well pleased. It almost fit inside the cowl without cutting an opening for the head. Actually the opening is beneficial for more airflow, and access to the glow plug and room for the exhaust would have required cutting the cowl anyway.

Power is more than adequate, although the ARF itself is lacking in strength and design. After all, it dates back to 1999 or so which is the earlier days of many companies' arf offerings.

Paben, what is your setup?
