Liki Tiki - RC amphibian model for twin .35 power.
Quote: - "It seems that just as most Class III airplanes are more or less jokingly referred to as being a modified Taurus (oz612) so could most current flying boats be related to the Sea-Cat (oz8658). Henry Struck probably gave little thought back in 1941 to the fact that the aircraft which he was designing would evolve as the matriarch of all subsequent flying boats. Undoubtedly, the Sea-Cat was, and still is, a fine airplane and served its design intent with no shortcomings. However, it was originally designed as a free-flight aircraft and this character seems to have been somewhat preserved in latter day multi-controlled flying boats. With due respect to Mr Struck's pioneering efforts and successes, it seems that modern day science and technology have elevated the state of the model art to a point where free-flight characteristics are no longer desirable and much less required in a multi R/C aircraft.
The design characteristics of the Liki-Tiki were intended to produce a full blown R/C flying boat that did not suffer from this FF/RC compromise. The current flying boat norm seemed to represent a lightly-loaded, under-powered airframe, with a high drag coefficient due to attachment of tip floats and engine pod. My desires were for a clean, well powered flying boat that would respond with the vigor of a Class III aircraft.
Tip float drag and inherent structural weaknesses could be precluded by using a sponson. The twin engines would obviate the pod..."

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.
