OK, I just bought my Magic Extra. Looks like a great plane. Now... all I need is to fix it up.

In the mean time, I might as well ask this question. I have this OS 40 FX, and I want to hover the MODELTECH Magic Extra. Problem is, I don't know what propeller to buy. 12.25 x 3.75 propeller doesn't seem to be in stock... What propeller should I use?

Also, I want to buy another engine just for this plane (and other future planes). I was thinking of a Magnum .53 or a Super Tigre .51, between the prices of the engines is a $10 difference.

Hope to hear from you.
