Tomboy event:

 

  1. Tomboy is a classic English beginner’s model which was often powered by a Mills .75cc/.045 cu in diesel engine. Plans were published in the November, 1950 Aeromodeller.
  2. Plane: either the 36” or the 44” span version of the Tomboy is allowed. The 44” model is basically the same plane with 2 rib bays added at each wing tip and one rib bay added to each tip of the stab. This is noted on the original plans.
  3. Minor strengthening of the fuselage structure (2-4 diagonals in the forward bays) is allowable. Modifications for DT are allowed.
  4. Power: any diesel up to 1 cc or any COX reed valve engine up to .049 cu in, including the ‘product motor’ (the one left over from the ready to fly CL planes). Any prop may be used.
  5. Fuel: 3 cc*, which is the capacity of a stock Mills P75 [.75 cc / .045 cu in]. Any fuel may be used, but no gasoline may be added to glow fuel for Cox engines.
  6. Flights: All flights are Rise Off Ground [ROG]. There is no max time. Fly as many flights as you wish. Turn in the longest time for Saturday and Sunday by 4:00 pm and the longest for Monday by 3:00 pm.
  7. Timer: The timer must stay within 50’ of the launch point. He may use binoculars.
  8. Entrants are encouraged to be at the CD’s desk at 9 am on Saturday for a group picture.
  9. Scores: Your longest flight over the 3 days is your official score.
  10. Plans: 

    -A check or PayPal for $6.00 [includes postage] will bring you a full size plan plus copy of the original magazine article. Send to: Al Lidberg, 1030 E. Baseline, Suite 105-1074, Tempe, AZ 85283.  aalmps@aol.com 

* 3 cc syringes will be available at the CD’s desk for fueling an empty tank or for use as an ‘eyedropper’ type tank. If the tank on a Cox engine has not been drilled for access to the needle valve, it is requested that you run the engine dry, then refill with 3 cc from a syringe. You should be able to get a quick re-start.
