Ian Walker’s Planes

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

Receiver: 35MHz

Model: Hopscotch

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,

4 ch. motor 200 watts. ESC 35 amps. Lipo 3s x. 1000. Prop 9 x 6.

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.

Ian Walker’s Snipe

Maiden Flight – 7-5-19.

Model – Snipe   X2
Spec – 40” span, 3 ch., AUW 21 oz., 13 oz/ sq ft., 140 Watts, 1200 Kv., 20 amp ESC., 3s x 1000, 7 x4 prop.

Nostalgia. The original was a 1947 Veron 20” span F/F rubber model kit. As a boy I built 3 and had many long recovery treks but was very happy to get a duration of 60 seconds.
The current twice size radio version will easily do 5 minutes and hopefully land at my feet. Progress!
