Hello everyone, I have this plane and it is currently powered with a Saito 62 and I would like more power. I can get a good deal on an OS FS81 and I was wondering if it would give this plane unlimited performance or if I should go bigger with a 90 size 4 stroke. I have my rudder servo in the tail and the battery just behind the firewall for balance, so the bigger engine shouldn't be a problem if I move my battery back, which is not a problem. Let me know what you think.
