RE: Guillows
I've had no prblems getting the Guillows airframes to fly. My first was the large A6M Zero. It used a small carburated nitro motor. It has been so long I cannot remember more other than it was 4 channels and this was before micro gear was around. I also remember it was fully sheeted and pretty detailed.
My first 16.5 Guillows was a Hawker Hurricane. It was built heavy so it was very fast but it flew.
After that I stuck to the 16.5 Hellcats. I use the stock kits wood and they fly very good. Just keep them light.
The biggest thing with the Guillows planes is to keep them light and don't crash, they are fragile but fly pretty good.
