I have a W.M. Chipmunk I bought used and don't have the manual. It has a Saito .90 in it. Would someone tell me what throws to use for high and low rates? Thanks.

Dick

Firstly, just make sure that on high rates the rudder does not touch the elevator. Rates are as follows:

Ailerons - 1/2" or 13mm
Rudder - 2" or 50mm
Elevator - 1" or 25mm
Flap - 3/4" or 20mm

For me max rate for elevator and rudder is as much as I can get it without binding them.

CG - 4.13" or 105mm

She does a great KE and if it tucks to belly or canopy just adjust the CG to get rid of the tucking. Have fun ... I loved mine.

Thanks, tIANci

Now, if I can just get to the flying field.

Dick - you will have fun. She is so nice to fly. I had 2 of them, 1 was with a ST90 and the other EP. Its one of the best scale aerobatic planes I have flown.
