Hi. is this a good engine to use on the Martin AM-1 Mauler size 40-60, Magnum XL 91 RFS 4 Stroke Engine? can buy new for $149.00
Here is the specifications of the plane. Also is the 4C 0.91 size the min or max for this plane. Would like to give this engine a try.

Thanks

Specifications:
All balsa construction. This model comes with Retract.
Wingspan: 1475mm (58 in)
Length: 1193mm (47 in)
Engine: 2C, 0.61-0.74 / 4C 0.91 size
Radio: 5 channel, 6 servos

It will be just fine

I just posted the same engine to your other thread. I have two magnums (th .46 XLS 2 stroke, and the .52 XL 4S) and I love both of them. The .46 is the only one in a plane so far, but it has a ton of power. People will tell you that they may take a little while to break in, compared to an OS, but the dependability after that is great.

Thanks for your help. Will go and re-read post.
