RE: Club Enya
Two R155's, one 240VT, one 120-4c, one 90-4c and one 60XF-III GM10 S AL-Chrome rear exhaust.
I really like the 155's, they are very fuel efficient and powerful. You need to do a few things to make them reliable for aerobatics and quiet them down. The 60 has the best cylinder/piston fit of any engine I have ever seen. Without the glow plug installed the engine can be rotated smoothly and easily thru TDC, with the plug installed the engine can't be turned over without a prop.
I would like a get a .53 for a small biplane.
I don't think they are being imported to the US anymore, The .53 is the only four stroke listed on the website and the two stroke count is down also.
