I purchased a built Royal Zero that had been hanging in a hobby shop that went out of business. It had been set up for a .60 sized engine. After updating and refitting and CG setting, the overall weight came out a little heavy(10.25 lbs. to 10.5 lbs.). I have been out of the hobby for about 15 years and too my recollection, that is a little heavy for that sized engine. I was hoping that some of you who may have had some experience with this kit can guide me on the proper engine. I have an O.S. 61 FX currently in it. Will that fly a 10.5 lbs. airplane? It does not have to be the hottest thing to satisfy me after so many years away from the hobby.

Any help that could be given would be greatly appreciated.

Thanks
