I thought I would build a pattern plane a bit different-and not expensive.
Also I wanted it to be legal -under 11 lbs and 2x2 m
Using the ZDZ40 RE engine and a can muffler- inexpensive and gasoline fed, I made a model with standard balsa foam wings and a stick and balsa fuselage.
The wing tail shape /layout is like a Giles 202-
final result weighs under 11 lbs.
It took some care and lots of testing for weight (grams count!)for all parts.
at 1287 squares - wing loading is 19 oz/ ft.
Flight characteristics are very good - No speed build up is required for any maneuver -
plane will fly very slowly and will also cut thru 20 mph wind as needed.
I used the new JR811 servos -ailerons 4x24" and a single servo on each works very well.
If you are sick of spending too much to fly pattern -try this approach-
The plane also will do hovers at a high idle etc..
It seems most guys are into ARFS now - but this approach is easy to do and frankly , flies the patterns easier than anything I have flown.
Has anyone else tried making a 40cc pattern model?
Let me know.
