Ziroli Corsair & Evolution 7cyl 77cc Engine
Hi, This is my first time posting here. I plan on building the ziroli Corsair in the near future. I was wondering if anyone has used the Evolution 77cc radial engine in the Ziroli corsair.

At 77cc the Evolution falls withing the suggested range of 62-85CC GAS. I however have no idea as to the reliability or power of this engine. In addition, do you plan on building it more as a sport model with medium details or full blown scale with every detail you can get in it? This will change the overall weight of the model and may require going with the biggest or even bigger than suggested engines. Retracts, flaps, every additional function adds weight.
My second concern is, this being your first post, what is your experience and skill level? Are you a seasoned builder or have you recently got into the hobby and are now chasing a dream model?
I would suggest you also visit this site. RC Scale You can join for free but are limited in what you can do. $20 a year gets you full access which is beyond worth it. You'll find build threads for the Ziroli kits there as well.

My Corsair build will be my first full blown scale project. My question stems from my lack of knowledge about the Evolution 77 radial engine. On paper it has roughly the same performance as the Zenoha G-62. But I'm interested if anyone has first had experience with this engine in the Ziroli Corsair.
Thanks

My Feedback: (4)
KGrenier,
I have one of these engines. I bought it with the intention of putting it in a Hanger 9 Corsair. I did install it in the Hanger 9 Corsair and was not at all pleased with the performance. This engine had no where near the
speed and pulling power that the DLE 55 I started with did. In my opinion, it was barely enough power to get plane off the ground and I struggled to get it back on the ground. It did fly once it was airborne and flaps and retracts were up but was a hand full. I did not use the exhaust collector ring and just let the exhaust pipes exit through the back of the cowl. I used a McDaniel ignition box and the recommended mix of a gallon of 15% glow fuel and a gallon of methanol. I ran engine on a test stand for 2 hours before installing it in plane. The engine overheated and sagged during flight. I didn't add any baffling but there was plenty of airflow through the cowl. As far as recommending the engine for a bigger airplane, I would say absolutely NO. I am looking to sell the engine I have as It is a cool engine and sounds awesome, but I wont put it in another airplane. Hope this helps
