Hi Mike, It's a very good starting point and well worth the outlay. Has saved me lots of guess work and I use it so often I would lost with out it. The best thing is that it can tell me motor, gearbox and battery set-ups that are certainly not suitable. Each time I have used it on a new model or when converting an airframe from IC to electric the plane fly's very well. Go for it !!!! John.

Its the best there is, BUT its ONLY as accurate as

(i) its data

(ii) Its assumptions.

Both are often inaccurate in a given situation.

Its a tool, not a solution. Your question is tantamount to asking 'how accurate is a spindle moulder?' and the answer is of course 'in teh hands of someone who knows how to use it, on suitable wood, better than

0.1mm, in the hands of a rank amateur on cast iron, probably to the nearests 5 inches, if indeed the operatorr or machine survive the abuse'

Its only $30 from memory - get it, and then join teh E-zone

I have used it on only one model - a Tracer kit converted to electric. The plane uses a 6S3P pack made up of 1500 mAH packs.

It was very good. The motor (an AXI 4120-18) and prop (APC 12x8 electric) drew 30 A at 21.2V instead of 30.5A at 21.4V. My biggest problem is that MotoCalc did not have a battery model for the cells I used, so I had to guess.

The plane flies beautifully. Since the CG never moves, I could put it where it belonged.

For $35.00, MotoCalc is a steal.
