Hi SM50,
I built a GP Super Aeromaster back in about 1996 and powered it with a YS .91ac. I flew it last Saturday and it is very powerful. Impressive verticle performance and will fly knife edge all day. Sorry to say I don't recall the weight. It is a great airplane.

I see a saito 1.3 twin on ebay. I believe it is a gasser. I did ask over in the glow forum but since you mentioned putting the Magnum in there I thought I may as well ask....how do any of you think the 1.30 twin would be in this model? Too big? Overpowered? I love the idea of a twin and I may be able to win that auction as well. Ya never know. But I first need to know if it is an engine to even consider for this model.
