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.
