About this Plan

Monitor. Control line speed model. The 160.5 mph Monitor. For McCoy .60 Redhead engine.

Quote: "The construction method is not new inasmuch as crutch types have been used some 15 years or more. It is, however, entirely hard wood except the channeling inside the cowl which is balsa. You start by grinding the fins off on each side of your engine until they are flush with the outer screws in the head, covering up and protecting the engine where necessary. This is done to reduce frontal area.

A Hell Razor pan was used, and modified by cutting rear skid off and filing all excess metal off. The engine was then mounted. A 1-3/4 Froom spinner was used with a 1/8 back plate turned on a lathe to keep it from binding on the fuselage when you tighten the prop. The fuselage top was sawed out to the shape of the pan, using a piece of basswood 3/4in x 2-1/2in x 18in then sawed to take engine..."

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.
