I had a WM Extra 1.20, too. I liked the small size because it works perfectly with these 1/4 scale motors. I set it up with the Saito 1.80 and it had excellent power to weight. I think DPM had it all wrong trying to go slightly larger than normal with a 1/4 scale. These 2-lbs engines are awesome... and on a smallish 1/4 scale plane they are really great for 3D. :-)

I'd buy a smallish 1.20 size plane that was fully 3D setup in heart beat. Something around 68" like the WM 1.20 Extra. Built light, fully airfoiled, all double beveled, 950 squares, 9.5-10 lbs true all up weight with a Saito 1.80... they'd sell like hotcakes. Horizon? Are you listening? :-)
