It was fun and run (fly) what you brought. Also 5 flying together with a horse race start. I usually built 5 of my design at a time. My old friend that was my caller when pylon racing built the wings and I built the fuselages and tails. My design had a 8% airfoil and was just shy of 3 lbs. Point it straight up and let go of the wing and its off like a rocket straight up and out of sight in about 8-9 seconds. The contest fun-fly airplane was the same design but with a thicker airfoil and would be out of sight in about 10-11 seconds.I could get into a revision of Open/ Outlaw pylon like the old days. The new jets make speed too easy.
Was going to make this same clarification to the inaccurate statement above. Was also a player back in the day in the southeast, first FMPRA which became SEMPRA organisation. And you know , as pilots, we could have handled faster ship. I tell guys how our individual lap times were slightly over 6 seconds and they find that hard to believe. One of the nicest aspects of the now demised Form One class was the " pretty plane" judging and the pride we took in the building of our racers. Was runner up for Best Finish award at the '79 Nationals in Lincoln,Neb. Now everybody flies ARFs in Q40 and Q500 and FAI. I, unfortunately, remember the good old days !! Miss that event dearly.40% nitro fuel is a hot sport fuel, but what we ran in Formula One was 65%. A .40 sized engine ran at 22,500 on the ground and unloaded 5,000 while burning 3 oz of fuel/minute. Straight line speed could touch 200 mph, though turning 180 degrees every 3 seconds dropped top speeds to about 175. Dry weight was 5 lbs, and a glow plug lasted one flight.
