Smoothie - 44in span FF Wakefield rubber powered model. From Model Aircraft, August 1950.
Quote: - "Smoothie may not be as hot as a Benny Goodman record but if you build and trim it correctly you'll have a model that can hold its own with any Wakefield. You may wonder why the model is called 'Smoothie' ; this is because it is fitted with two anti-vibration formers which you can see on the plan marked 'A' and 'B'. These stop the motor from hitting the sides of the fuselage. This, together with the 'S' type hook makes the transmission from rubber to propeller almost free from vibration. Using a 16-strand motor combined with a fine pitch propeller the model has a terrific climb followed by a tight circling glide, This is obtained by making the model balance at 75 per cent. of the chord back from the leading edge; although this is only advised for high pylon models, no trouble was encountered in trimming under this set-up. The model was developed from my previous experience on a streamlined Wakefield, where it was found that locking all the components (wing. Tail and fin, etc.) into position was a definite advantage. The model if trimmed could be taken straight from the box and flown in a contest without any previous trimming. This eliminates the risky test flight before a contest..."

Previous scan version.
Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
