MEN Trainer (oz4101)
About this Plan
M.E.N. Trainer - Radio control trainer, with undercambered wing. Scanned plans for MEN trainer with additional 2nd sheet showing a twin-engined version of the model. The scan is missing a small section at the right hand side of sheet 1, so the tail control surface outlines are missing.

User commentswhat is the dihedral of wing. no braces shown. thank you

Hi, Steve. I just looked and the previous comment is correct: there is no information regarding correct dihedral for this airplane. A good start would be six degrees/3.0 inches per panel, which works out to raising one panel six inches with the other one flat on the board. The airplane should have good yaw/roll coupling at this number.

Steve, I have a plans built example of this model with literally 100's of flights on it. I just took a measurement of the wing with one panel flat on the bench. The other wing panel is raised 5 inches at the tip (though 6 inches would likely work fine). Be sure to take the measurement at the leading edge as the undercambered airfoil makes a measurement at the spar higher. Each wing panel has a washout or twist such that the with the leading edge and wing root flat on the bench, the outboard trailing edge will be 1/2 inch above the bench. I can affirm that the yaw/roll coupling is very good despite the fairly small rudder.

* 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.
