I had a saito FA80 so I used it and the plane flies GREAT! It balanced perfectly with no weight added (the 80 is 3 oz's heavier than the 72) and power is super with the APC 13-6 prop. It will also fly quite fast without flutter and do all the manouvers except a good elevator or harrier (too heavy and stalls out).

Nice sport fun fly plane! I am glad I got it.

PS. I have not owned an MDS but havent heard anything good - which in itself is not good. On the other hand, have not heard or experienced anything bad with saito, OS, webra or rossi engines all which I own and run.
