Rate Settings for AXN

Hello Bruce et al,

Assuming normal mechanical setup of servos on an AXN, what are recommended rate settings on the radio for a novice? For basic flying should I use 100% rate on rudder, elevator, and ailerons... or something less? Should the expo feature be used? I have a Spektrum DX6i radio setup.

Many Thanks, UAVman

I don't operate a "Spectrum" so I'm going to assume that "rate" means degree of movement with 100% being maximum movement.

I you are new to RC I would recommend "rate" for RUD, ELEV be set at 50% and AIL at 75% with EXPO for all at 80%. THR rate 100% and EXPO 0%. Experiment with these before throwing the AXN in the air noting the movement of the control surfaces.

These settings will help you learn control in a calm environment, not recommended for any aerobatics as you will quickly run out of sky with not enough control to recover.

Height will always be your friend.

If you don't have someone with experience to coach you try "poweroff" testing. This is simply centering all sticks and hand launch into the wind at a level flight say shoulder height, now aim for a ground spot 20m away.
Use the ailerons to keep wings level and elevator to extend the range with out stalling, allow the plane to land. Doing this gives you a few things to look at, CoG is correct, any minor trim adjustments and how much control you have with rate & expo settings.

Sounds like very good advice cynr100. Yes, on a Spektrum radio "rate" means amount of throw for a given control surface. I will be setting my second rates using your advice. I will also be using expo on the second rates. Have been doing some on-line research and now fully understand what "dual rate and expo" means. I think using these radio features will make flying the AXN a lot easier. I can always tweak the values once I have some hours on my flight log.
Many thanks for your comments!

I know Bruce is busy, so maybe he doesn't follow this thread anymore?
