Default Model for a Cox Pee Wee 020?

Was given this engine and thought it would make a nice change…

So looking for recommendations for a suitable model, preferably a Guillows style scale model for use with 2 channel aileron/elevator radio or some high wing rudder/elevator suitable for today’s tiny r/c equipment.

Would the 28” span Guillows warbirds be suitable?

Sturdy balsa sheet fuselage to learn how to operate and fly with a PW engine would be way better than a weak
stick plane meant for inspiration more so than lots of functional RC flying.

There is a kit manufacturer called Willie Nillies that might have what you are looking for.

28" span Guillows conversions would be a nice way to go if you can keep the model to around 5 to 6 oz in RTF condition. The PeeWee won't pull much more than that and still give sporty performance that you'll be wanting from a warbird style model.

If you're into building from plans there's literally hundreds of good options to be found on Outerzone that will give you anything from gentle trainer like flying to sporty aerobatic flying from that same PeeWee. Since you were asking about an aileron and elevator warbird style setup I can recommend the Flipper biplane design flown with rudder and elevator.

In it's 18 inch wing span and a PeeWee engine it might be more than you want to deal with. Reports say it's almost manic in its response. But through the magic of the poster printing option available in Acrobat Reader you could print out a 22 inch span version and it should be a delightful flyer by being just that little bit bigger.

Don't discount a well designed R-E model in the aerobatics department either. With the generous dihedral and some airspeed a model like the Flipper will perform rudder rolls that are snappy by any standard.

Thanks for the ideas.
I am definitely leaning towards building from a plan, I have been doing that for several decades…
Already downloaded several candidates from Outerzone
I think I’ll choose a R/E scale looking bipe just to keep things from happening too fast until I see how well I cope with such a small model.

Weight is the key issue followed by drag. A PeeWee is actually right at home on a lightly built monoplane design with up to 36" span. But probably more at home with 28 to 32" span if some casual aerobatics are intended. And with a biplane that behaves somewhat gently until pushed into a dive for speed I'm thinking more like 22 to 24" span. With somewhere around 28 inch span being a good size if one wants gentle flying and enough drag to prevent any quick aerobatics.

The key is to keep the weight in check. 6 oz is great for something that climbs well and has some aerobatic potential. 8 oz will still fly well if there's enough wing area. But the climb will be somewhat lazy. 5 oz in a smaller package? Great fun if one's nerves are up to the job!

A design that I've admired ever since I first saw it back in the Oct 1966 RCM magazine is this Lil' Bipe by Art Schultz.

But at 31 inch span it would likely be a very lazy and slow climbing model on a PeeWee. And big enough that I suspect a lot too draggy for aerobatics even with a good spiral dive to build speed. But if that's what you are after then it might be a good fit for you. Me? I'm thinking small schoolyard size and a reduction to 26" span for closer in flying with a 60 to 70 watt electric motor for some lively aerobatics. But of course then I have throttle so I can switch easily from "mild" to "wild".

Due to landing on grass the nifty looking wheel pants will have to go in favor of some large skinny wheels that cut through the grass and roll more easily. That's where the Flipper design with some big flat tundra tires that sits on top of the blades of grass might come in better. And the fat tundra tires tends to fit the looks of the Flipper.

And of course there's so many other fun and good looking designs. Whichever you decide on I hope it's a good match for how you want to fly it. Or at least that you can tune it to be so.

Back in the early 70's I flew a rudder-only, .020 design kitted by Ace R/C. It's name was Dick's Dream, named for Richard Adams, inventor of the Adams Actuator. The plan is on Outerzone. Look it up and check it out.
