September, 2004

Martin's IFO was inspired by the RTF plane of similar name, only it's smaller - 7" span. I wanted to get some experience with ailerons, so an elevon plane seemed appropriate. I found this plane flies better with the more powerful 3 ohm 6mm motor, though it is quite lively with the 4.5 ohm. Switching to a lighter carbon prop, and 60 mAH battery, made it very lively.

I have had lots of fun with this plane. Most flights end in a crash, into trees, concrete paths, bushes, etc. Yet nothing has ever broken on it. I have improved my flying skills enormously with this plane. Aerobatics like loops are quite doable, though I have never got a decent roll out of it.
