About this Plan

Sleeker. Single channel RC model for .049 power.

Quote: "A 32 in span single channel sports model for rudder only or rudder/elevator controls.

SLEEKER originally started life three years ago and spanned 24 inches, the necessary inspiration for this model came after reading an article about miniature R/C models in an early edition of RCME. Powered by the Cox Pee Wee the little Sleeker flew straight off the board and was capable of the usual single channel range of aerobatics, plus our own particular favourite of flying the model in a tight circle around ourselves (control line fashion) until we were either very giddy, or the model ran out of fuel.

Whilst on the subject of single channel aerobatics we feel a word about escapements won't go amiss. Contrary to most other single channel flyers' beliefs, we definitely prefer the compound type particularly the 'Elmic Compact', which we feel to be far superior to any sequential type.

When flying fast and low it's nice to know that two presses will get you out of trouble when in a tight right bank and vice versa one press in a left bank. Imagine using a sequential escapement in the same circumstances and you've forgotten what your last signal was. Well most flyers know the answer to that one, you don't get a second chance. As for the view that compound escapements are no good for aerobatics because of their slower response, this may be true, but it certainly doesn't show in the flying.

It was the introduction of the silencer rule that killed any ideas of progressing with the 24 inch Sleeker. The Pee Wee refused to run well enough with any metal object strapped to the cylinder, so instead of installing a bigger engine we decided to build a bigger model. About this time single channel competitions (spot landing) were popular in the South Eastern Area, with some pretty stiff opposition from clubs like the Sevenoaks MFC who under the direction of chairman David Bishop have done a lot, competition-wise for single channel flyers in this area.

Getting back to Sleeker, a 32 inch span version was soon drawn up, and we come up against the question of what engine to use. The answer was pretty obvious. The Cox Quiet Zone was just becoming available in this country and with its integral fuel tank and really efficient silencer, what more could we ask for? Three 32 inch and one 30 inch version of Sleeker have so far been built using this engine, and all have flown straight off the board with identical trim. It was whilst flying these that we decided here was the perfect model for the spot landing comps.

Sleeker is very quick and easy to build, very crashproof, easy to cart about and turns without dropping its nose - this is a definite advantage when making that final turn towards the spot..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

* 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.
