Status: offline 		Ive got an aresti and I was wondering what the best engine would be for it, they recommend a .40-.58 2 stroke and .56 or .72 4 stroke.. Could i use an Os 2 stroke .61 fx or would that be to much, or would it just be perfect. And would the Os 70 4 stroke be better or the Saito .72 4 stroke be better? And since the .91 Os Fx weighs the same as the Os .61 Fx could i use that instead?, thanks

Status: offline 		The 61FX would be fine. The Saito 72 is a bit lighter but also a bit less powerful than the OS 70 Surpass so you'll have to evaluate the weight vs power issues with those two engines. The 61FX would be more power and less costly than than either of those 70 size four strokes. The 91FX would be too much power in such a small plane plus prop ground clearance might be a problem as well. Andrew - Please see the rules about duplicate "spam" postings.

Status: offline 		The Saito 72 would be a perfect mach for your bird. Lighter wing loading means softer landings and takeoffs in less feet, whant more power, the Saito will take 20% nitro with no problem, a Wprop is a bit wider which makes more pulling power, wind that Saito up, it likes rpm.
