Post by: James C. Martin on May 09, 2014, 01:47:55 PM
Anyone have an opinion on witch os max 46 would a better choice for a ringmaster imperial I have a la-s .46 and a .46 fx converted to control line the ringmaster imperial has a 52 inch wing with flaps and built up fuselage and tail feathers  or is this too much engine for this aircraft?

I dunno about the FX, but the 46LA should work fine.

   Any good running 35 or 40 will be just fine with 10-5 prop, maybe 10-4 if alittle to fast.

It might prove a bit too much.

Hi James,

One problem is that the room for a fuel tank is pretty small in the Imperial.

I'm using an Enya .29 at present, and probably gonna switch to the Enya .35 I got from Bill Little.[same size and mounting], it flies great, here's the maiden flight. P/S the little guy is my grandson who loves to trip the stooge: http://www.youtube.com/watch?v=gLlWbCPDZcE

I my self am finishing the first kit of the Ringmaster Imperial that Walter Umland produced.   It is shown with an LA .46 on the plans and that is what I am using.
