With straight wings and Ailerons this "COULD" be an excellent modern day performer.

The benefits of Foam and modern power options will
turn this Pussy Cat flier into a serious Foamy Contender.

That's my plan--straight wings with c/fiber tube spars, at least one pair ailerons, etc.

That's a great start.

Two sets of ailerons would be more 3D like ! !!

Ken Willard built a later design of the Schoolgirl when more advanced RC became available. He eliminated the bottom wing to create the "Sophisticated Schoolgirl". If you're looking for a design that's faster and more aerobatic that is a proven option.

I've been searching for the old magazine article Ken wrote about the Sophisticated version but all I can find so far is the RC Modeler article about the original Schoolgirl.

Question Bob:

What's written on the little parts around and below the rudder?

Sophisticated Schoolgirl


Found Ken Willard's article on the Sophisticated Schoolgirl. It was right here in the Vintage & Old Timer Plans Archive. It's an interesting read. 11oz for three channel proportional radio gear back then!

Wow Good find..

IF you had a 2 oz servo back then it would be equivalent to
4 ea 12 gm servos today.

But then today a Micro processor is much lighter than
even a single Transistor back in those days !

It's hard to believe, But we still were having a good time.

I imagine just having the ability to turn your free flight airplane around so it didn't fly away was a major advancement in technology.

That is how I looked at it also. I built a few and never got the nerve up to lose them, so they died of hanger rash.
Then started flying RC

FF models make terrific RC trainers or just fun slow flying models for
the pure joy of flying.
Especially on those calm summer evenings.

I had an 88" Bucanneer with a 4 stroke 60 on it .
Pure joy to cruise around low and slow or even doing figure 8's while touching just ONE WHEEL down. then the other.
Of course those were 6" inflatable Drexler tires too :-)

I should build another woodie and do an electric power option this time.
No oil, grease or vibration to ruin it.
I still have the original plans.

I have a Foam versino of the Buccaneer with a woody wing but only 48" span.

It's a joy to just do a zillion T&G's with .

Schoolgirl #2


Has it really been over a year since I built the first foam board Schoolgirl? Time for Schoolgirl #2. This one is built sturdier. DTFB with the paper left on and pre-treated with Minwax wipe-on polyurethane so the paper doesn't delaminate. The nose is double thick and there are bulkheads fore and aft of the top wing. The first Schoolgirl flew nice with a 1806-2200kv motor but this time she's motivated by a 2212-2300kv. Two 15 gram metal gear servos because I'm tired of plastic servo gears sticking.

She's still the well mannered easy flier Ken Willard intended her to be but now there's plenty of thrust when you want it. She's a whopping 18.5 ounces with a 1300mAh 2s Lipo on board. That's probably still lighter than the original balsa wood models. I painted her exactly the same color and trim as the Top Flite balsa wood kit I built as a boy back in the early '70's.
