RE: Extra 300, 230, 260,
ORIGINAL: MonkeyBones
I'm wanting to scratch build an Extra 300, 230 or 260 I'd like for it to be in the 80-84" range. Anyone know of any of these plans that would be for sale any where???

A bit larger than your specs, at 96", but the rear fuse and hinge lines are far enough off scale to make for a good bit of work getting it right.
The original design (and the kit itself) were from "R/C Extras", which I think is no longer in business. Ace re-marketed the kit under their moniker until Tom Runge sold Ace to the guy in Hong Kong.
Sheeted foam wings with laminated ply spars and stub spars, sheeted foam turtledeck, cockpit area, and foredeck, built up rear fuse and tailfeathers. The laminated spars overlap inside the fuse and bolt together, so there is no wing tube/receiver to mess with.
Not a bad kit, but the elevator and rudder hinge lines are all wrong requiring the fuse rear to be extended by about 2".
The original hinges are not scale at all, and the flight control surfaces' leading edges are all wrong; the 1:1 has round L/Es on the flight control surfaces, so there's a good bit of work involved in converting the ailerons to true scale hinge lines; I used 1/2 half-round Ash and it worked nicely. Robart giant hinge points work if embedded in stainless tubes in the T/E.
After a fair bit of work you'd have a 'stand pretty close scale' version of the 230.
Target weight is 18 pounds depending on the engine and covering selected.
If you're interested, that is . . .
