In the process of building a Sig Astro Hog.

I want an engine to get me off the grassy runway. Planning on putting an O.S. FL .70 4-Stroke on it. Will that be enough to get me off the grass? Grass is usually about 2 1/2 inches high. I also plan on doing some nice manuvers with it.

Also, on the tail dragger verson, I noticed pics of astro hogs with "aluminum" main landing gear rather than the wire gear built in the wing. Is there a reason for that? I'm not a professional builder.

Need all the help I can get.
