I'm new to RC and computer radios. Have been flying a trainer with a standard 4 channel radio. I've purchased a DX7 with AR7000 receiver's to put in my trainer as well as a Sig Mayhem 3d plane.
I'm confused about mixing and how and when to setup it up.
Also the Mayhem is very touchy to stick movement. I've setup Exp on all controls with 100% on each switch as position 0, and normal on position 1. Is 100% too relaxed. Should it be 50% instead?
How do you know when and how to setup mixing? Ail>Rud and so on.
I've searched around but I'm unable to find answers to my questions. Maybe we can gather enough information to make this a sticky for others in the future.
Thanks,
Kasey
G'day Kasey,
Set your Dual Rates, elevator, ailerons & rudder, low rate, to 50% or 60% of high rates, this will reduce the throw of the control surfaces, & make it much less sensitive, forget about expo until you are happy with the way the planes flys.
If you need expo, add it later, in case you don't know, you can have a low rate, with no expo, & a high rate WITH expo, or visa versa, but set up the plane using your rates first, then play with expo.
Exponential, only softens the feel around centre of stick travel, but once you move the stick past the expo point, you get linear movement, & bang, you find the plane is too sensitive.
In the case of the DX7 it is positive Expo you need not negitive, be aware.
You should only need rudder/aileron mixing with high wing slow flying aircraft, like a J3 Cub, & so on, your tainer won't need it, you may need to use 2 servos for the ailerons on you Mayhem, in which case you would set the wing type to Flapperon, & plug your right aileron into "AIL" slot & your left aileron into "AUX1", your ailerons will now work properly.
Read you manual, on the DX7, & talk to guys at your club, if you need any more info on mixing.
