Razor:

It's not started yet but should weigh roughly 7-1/2 - 8 pounds.

Now don't forget I'm not going to be 3D'ing this thing so static thrust really doesn't do much for me.

Tower engines are pretty rare up here since most Canadians don't use U.S. based suppliers. Duty and other fees make it cheaper for us to buy them here, so Tower is out.

I think a 1.08 - 1.20 is overkill and to heavy so they're out.

I guess I'll go with the Magnum .91 or the ST 90 whichever I'll get the better deal on.

Thanks for everyones help and input.
