My winter project will be a 1/4-scale Fairchild 24W, enlarged from 1/4,8 scale plans. (from 90" to 108" span)
The original plans was designed for a 1 cu.in. four stroke engine
What would theoretically the (four stroke) engine size be for the 1/4-scale model, in order to get the
corresponding performance? I assume there is a formula

Thank in advance,

Get the 1/4 scale plan from Nexus. Yes, they (nexus) are a pain in the butt to deal with and the plans are messy, - but it is possible to make a model from them.
I take it for granted that you use the radial cowl.
As for engine, a 1.50 or 1.80 Saito, or 1.55 Enya FS would be ideal.
Hej då!
