About this Plan
The Gnat. Control line 1/2A team racer.
Quote: "Two versions of this model can be built to suit any of the 1/2A Team Race rules. 35 or 50 sq ins, for 1 cc or 1.5 cc. The Gnat Team Racer, by Ron Moulton.
No official rules exist for Class 1/2A team racing - as yet; but each year the East Anglian Team Race Rally organised by the Cambridge MAC includes what is becoming a popular new class among the events of the day. The 1953 Cambridge Rally attracted a couple of dozen of these baby racers, but unfortunately most of them were overnight specials and were not eventually entered in the contest.
The Gnat was in fact one of those specially built for the Cambridge Meeting and though it cannot be reported that it won first place, it did at least prove that it could cover the required 50 mile eliminating heat non-stop at an airspeed of between 45 and 50 mph. This is the 35 sq in version, fitted with an Allbon Spitfire, the maximum capacity engine under the .99 cc limit imposed, and the best airscrew is a wooden 6 x 6 geometric pitch.
One difficulty not readily realised is that with such a small wingspan of slightly less than 14 in, propellor diameter is near to 50 percent of the span and often more than half the fuselage length. This means long undercarriage; partly overcome by the use of an inverted engine..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
