Congratulations! It's a neat system. I have now put my Echo twin cylinder engine on my Giant Stik, but I had a Poulan 42cc on it running Gas/Glow. It pulled really well. That Giant Stik is fairly heavy, but the Poulan didn't seem to notice and would pull it straight up until I would quit. Very short take off runs as well.

Here's a couple of pics...
