RE: The Best and Worst 1/12 scale Warbirds
Here are my two Airkill planes, the Bearcat Conquest made up (sort of) in the American Jet Reno racing markings, and the P51-B model. They both have OS32SX power which pulls these small planes close to 150 mph (radar confirmed). I also have the Airkill P51 Strega kit still in the box.
A few years ago, our club made 1 attempt to pylon race 1/12th scale, but lack of interest killed the event. Oh well. Nevertheless, it was fun to race them the one time. We were limited to .25 size engines for the race, but we could use performance pipes. With the os25fx, the Bearcat was clocked at 125 mph.
Have someone else hand-launch them for you until you get comfortable with them. They will torque-roll left out of your hand, so be prepared. Once in the air, they fly great! I can yank them around pylons without fear of snap-roll. For landing, just throttle back, and keep the nose down. Once over the threshold, kill power and let it settle into the grass. Make sure the prop stops horizontally when you bolt it on or it might catch in the grass during landing (ask me how I know!).
Unfortunately, I believe that these kits are no longer available from Airkill.
