About this Plan

Mini Comet. Radio control sport model for .8 to 1.5cc engines.

Quote: "TYPICAL of the Japanese designs for rudder-only control is the very popular Mini-Comet produced as a kit by Schmitt-Hobby and published as a plan in the specialist radio control magazine 'Radio Control Technique'.

A specially attractive feature of the model is that it can be made with either .of two wings. One has a standard flat base airfoil for the lower powered engines and general sport flying, whilst the other is a much thicker wing of semi-symmetrical section for full aerobatics. This enables the Mini-Comet to accept engines of up to 2.5 cc. Both wings are tapered and have a liberal area of sheet covering plus cap strip strengthening over each rib, making a most robust 37-1/2 in span which matches the strong yet very simple fuselage. This has 3/16 thickness sides and cross-grained 3/32 sheet top and bottom. The ease of assembly with the thick sides and rectangular formers brings this model within the capability of the near-novice, and as the plan shows, the design accommodates various alternative installations such as the push-pull, or standard torque rod types of escapement.

The tricycle undercarriage makes,-it ideal for taking off from airfield runways and the sprung nose leg is also an asset for accepting the shock of landing in rough ground.

Disposition of the equipment in the fuselage depends entirely upon the weight of the engine used and if a heavier (diesel) type, it will be an advantage to shorten the nose and utilise a motorised rudder servo, which will help with its slight extra weight... "

Mini Comet is a very good design. It was my first successful Single channel R/c model. Made some time in 1968 [more pics 003]. It was scratch built from the plan. Instead of tapered wing, I was advised to make straight wing. The first model was powered by Frog 1.5 cc Diesel engine. Homemade fuel tank. Home made Single Channel transistor Tx (27 Mhz) and Super- regenerative Rx. with Elmic Conquest escapement. Then another was built with OS PET .10 and then Enya .09. Excellent flyer. I really learned my R/c flying on this model.

* 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.
