About this Plan

Iota. Free flight power model. This is a modern redrawn plan in PDFvector format.

Quote: "This model conforms to the new international class for power duration models, if powered with a 1 cc engine. The performance with an ED BEE is from 3 min 20 sec to 4 min in non-thermal conditions with 20 sec motor run. The model is trimmed to fly to the left both, in climb and glide, with 1.5° left sidetbrust and 5° positive incidence to tailplane. Because of this trim and the high pylon there is absolutely no stall or loss of height at the end of the motor run. Iota is therefore very well suited for ratio-contests under windy conditions, when a short motor run is desirable to avoid OOS flights. Because of its great stability, easy trimming and construction, the model is an excellent beginner's model, and can be flown by more experienced modellers with one of the hot 1.5 cc engines..."

Quote: "The Iota is a power contest model by E Brendeng from Norway. The original was powered by an ED Bee and with a 20 second motor run turned in flights of between 3mins 20 secs and 4 minutes. This is really good considered the Bee wasn't renowned for its high power output. Plus points for the design include easy to build and trim making it a good beginners model. In experienced hands power of up to 1.5cc could be used. As always with my tracings please use care if you build from them."

* 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.
