Fun Tiger - Medium sized sport/aerobatic model span 54in for .35 to .40 motors.
Quote: - "Here is a model that was designed specifically as a low-wing trainer. The idea was for something to supersede my much-modified Tauri (oz5162) which had a Merco 35, shallow dihedral and strip ailerons. I wanted to fly a low winger but not the 10cc big chaps, at first at anyrate. Unable to find a suitable existing plan, I had to sit down and dream up my own, which resulted in Fun Tiger.
The features I felt I wanted were as follows: first, a semi-symmetrical aerofoil section for the wing - the stall being less tricky than with a fully symmetrical section. Secondly, a structure that could be built very light which, again, would help to produce gentle stall characteristics...
I used inset ailerons because I have found them to give less trouble than the strip types, in that they do not warp, and also that one can see at a glance exactly how they are set, relative to the rest of the wing. A full-span, one-piece elevator was employed, to obviate the possibility of asymmetric elevators, which one always risks with the joined two-piece type. This also enabled a more tidy push-rod linkage to be used, as an extra bonus. Otherwise, generally, I wanted a sort of scaled-down multi-aerobatic type of model, for Merco 35 - one that I could make the transition from high to low-wing flying with, and yet be able to progress to some sort of schedule type aerobatics, without having a screaming bomb on my hands. Then, at a later stage, and when I felt like getting to grips with a .61 up front, I could make the further step, up to the standard acrobatic sized model with much less apprehension. When complete, the model weighed some 4-1/2lb..."

* 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.
