About this Plan

Weepy. Free flight power model for .2 - .5cc engines. Wingspan 30 in, wing area 144 sq in.

Quote: "A semi-scale design especially for the Cox Pee Wee by Dave Platt.

When the Cox Pee Wee engine became available from model shops recently, many modellers took the opportunity to obtain one of these amazing little American 0.020 powerpots. The power obtainable from this motor nearly equals that of the average 0.5 diesel - for most applications - and its tiny size and weight immediately conjure up thoughts of sub-miniature FF power ratio and scale models. Unfortunately, however, the power is a little too much for truly diminutive models.

To date the usual application for a Pee Wee seems to be a converted rubber-model or glider, but I thought that a design especially to suit the potentialities of the motor would be much more satisfactory - hence Weepy.

This model has 1 sq ft of wing area which gives it a 'high-performance sport' type of flight, with ratios of around 10. I can recommend this model for owners of 0.5 motors, but if you install a good Dart or a 0.08 cc motor, go easy on the power at first.

Construction is true beginner's stuff. The original was completed in about seven hours' building time and for a cost of less than 5s. less dope - hardly expensive! The appearance of the model rather inspires thoughts of PAA load.

I haven't tried adding any weight to my Weepy yet, but no doubt I shall before the model is much older. The all-up weight of the original is 4.3 oz, but no effort was made to achieve light weight, 3.75 - 4 oz should be easily possible if load-carrying is required... "
