ARF or KIT?
Most of the '90' size ARF pattern ships were designed around .90 4-strokes so the weight of the Webra 1.20 is comparable. You can also get wrap-around headers made by Karl Mueller for about $50 (custom made to your specs - first class quality).
The MK Topstar 110 would be an excellent kit choice (available from Singapore hobbies - 2 versions: all wood kit or pre-sheeted foam wings, and stab). The wood kit costs about $310 shipped. The wood/foam version is about $460.
You can also check PAC's website for some of the older designs designed for 4-stroke 1.20s such as the Desire and others.
Good Luck,
