Good job on the video, Fred. That looks like fun. Thanks for telling us about the planes and how to do it. I notice a lot of the engines are unhappy during the initial rollout, but all settle down and run after they get airborne. Would bladders help that. If I understood correctly, the clock starts when it starts rolling, and a lot of time can be lost or gained during that burp phase.

both John and Dan had a coffin tank with the pickup at the front of the tank, we think the fuel is being pushed aft during takeoff starving the fuel for a 1/2 lap. The tank I use is a normal pickup at the back of the tank without any problems. There is a whole science to the tank design for speed that I don't understand having to do with keeping the engine from going too lean or rich during the flight.
having said that Bill also probably had a coffin tank with no problems....beyond my experience
Dan is still working with his tank

lol yes, a bladder would help tremendously however they are not allowed. Suction tanks only.

If watch a speed model take off, they don't excellerate like the Quickie race type planes. Time them for 2 laps from start and you will probably see the reason they sag on take off with front pickup.

This is looking serious! One o them has a full wave pipe!

Who was that guy that predicted pan rats and tuned pipes? Should be interesting to see how fast it goes or blows up.
