This started life as a Delta wing model and then had an upper wing grafted on - still needs some work

The original "Oblong" was a plan by J J Rutter in the 1994 Radio Modeller, with 50" span and 4 channels for  40 glow motors. I have scaled it down to 36" span (for obvious reasons) and electric power. Materials are balsa, spruce and ply.

Motor: 145 watt E max 2822 1200 Kv (£ 7)

ESC:  20 amp ESC with BEC (£7.80) 

Servos: 4 off E max ES 08A giving 1.5 kg.cm (£ 3.25 each) Battery: Polypower 3S x 1000 lipo (£6.90). 

Prop: 9 x5

Wing area: 300 sq ins

AUW:  30 oz

Flying surfaces taken from free mag plan called Bellhop. Fuselage own design. Span 39 ins. Wing area 290 sq ins. AUW 26 oz. Materials balsa, spruce, tissue,

Forward swept flying wing, originally 24 inch span F/F for .01/.02 glow motors.  Plan published June 1965 in mag. Model Aircraft, now on Outerzone, designed by Eric Clutton.

 

Test flown by Dave Barker he reported all OK except for a little tweaking in the up elevon area.

 

Model  COIN- FOO, plan from Outerzone 

Originally from 1979  U S magazine “ Model Airplane News” for small glows.
36” span,cabin r/ c , 230 sq “, 20oz, 140 watt motor, 3 s x 1000, 20 amp ESC, 7 x 4 prop. 3 ch.

Would be interested to hear if anyone knows where the name originates.
