About this Plan

Army Rat. Control line Rat Racer model.

Quote: "Army Rat. The idea of a multi-purpose rat-racer that could be flown in Class B and C speed, rat racing and balloon busting seemed well suited to the needs of military modelers. The Army Craft directors requested a model design to suit these requirements. The ARMY RAT presented here is the result. It can be built quickly and cheaply and is easy to transport. Two modelers owning different sized engines could team up with one model and by changing engines enter different contest events where permitted.

The ARMY RAT will do a lot of flying so it is ruggedly built. Hardwood is used in most of construction since it is easily obtainable from Craft shops and cheaper than balsa. Elmer's Glue-all is used throughout assembly for strong hardwood glue joints. The landing gear can be cut from 1/16 in 24st (or equivalent) aluminum stock or a deBolt R/C model gear can be used. The wheel size should suit the flying area. Smaller wheels can be used on smooth concrete or black top while larger wheels will be necessary to get over bumps on grass or dirt. It would be a good idea to keep several different size wheels in the tool box for changing to suit different contest conditions.

The various contest events will also require different size fuel tanks. Speed events will require a smaller tank than the 500 lap race. Tanks should be made removable as shown on plans and block balsa rear fairing should be cemented to each tank.

Start construction with the fuselage crutch. For .15 size engines bass can be used but maple, birch or oak should be employed for larger engines. Cut to length and spot engine in place at front. With tail end held together, drill engine mount holes..."

Notes

* 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.

Scaling

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.
