I think a Norvel .061 would probably fly it fine, but it would probably need nose weight to balance properly. Mine needed 1/2 oz on the firewall(electron-wall?) with the recommended brushed motor setup. To play it safe on power and balance, the Norvel .074 would probably be a better choice. If you don't like Norvels, an OS .10LA would work well, as a Thunder Tiger GP .07 would also. These last two choices will have less power, but may be less finicky than the norvels.
