DLE 55RA
Great engine, affordable and reliable. I have a lot of experience so far with DLE engines from their 20,35,55 that I'd say to anyone use this brand.
The RA will fit perfectly as is and run fine in that plane. Use a Xoar 22x10 prop because the engine remains loaded in a dive and the reeds are not floating causing that strange sound. Use an NGK CM6 plug do not use the DLE plug. It's garbage, I tried it once to see how long it lasts and the only dead stick I had was due to that plug.
Plenty of power!

Here's a 4-blade on a 50cc engine:

I've got the same prop on the same airframe with a G-62 but haven't maiden-ed it yet.

I have a dle85 in mine with a 24x14 prop but I will never go bigger than a 60cc ever again. All you do is chase vibration problems. A friend of mine uses mostly all dle55RA engines and he is always flying and I'm always fixing cracks. I think the 55RA is the perfect engine for these giant top flite planes. I am currently building the top flite zero with the dle61 but I have had to butcher the cowl because its a side exhaust. That rear exhaust on the 55RA makes things a lot easier. He uses the Bennet Mufflers instead of stock. As for the four blades, I tried it a Biela 20x10 once on a 60cc and screwed it to the wall of my trailer for decoration. I like my warbirds to be pretty fast and the 4 blades aren't.

I have a ZDZ 80 in mine and the plane and engine are 11years old. Hundreds of flights. Mine is a kit built so I did beef up a number of areas including the engine box/bulk head area. The ZDZ is one of 3 that I have and they all run flawlessly.

surely I must thank all your valuable opinions,and from Spain thanks you,The DLA 55RA has the cheapest price but i must admit that i like much more the saito fg 60 aeshtetically
but it is more expensive:At this point there a lot of job to do wiht my bird
i can keep the decision for a while ,will se what i will do!
