Rudder turns the "nose" of the quad. Same as it would on a heli in heli mode.

I use same approach with all my collective pitch helis. Always start and learn them at 100% with around 30%Expo. Rudder always at 100% with no expo. I feel that you should learn how to fly it by design and not tame it down. Better to get use to aircraft under calm and windy condition using its maximum abilities. Tame it down (lowering throttle curves or D/R) only for testing or some indoor flying.

Outside I always fly at 100%. I'm new to Quad so I figured I'll ask and since we are dealing with some gusty condition, assume that the higher rate will help.

Got it. I think I'm going to enjoy this aircraft. My 120 size cp heli would do the rabbit hops in the gusty wind.

It's a lot of fun. I only flew fixed pitch, but after flying a quad I'm hooked! It's like the best of both worlds to me and best of all no moving parts so much less time trouble shooting. There have been crashes that would have destroyed my helis. Just picked it up and kept on flying. lol

Yep, that's why I liking idea of trying Quad as I spend alot of time between flying, fixing and ordering parts for my cp heli. Can't wait.

Airplane mode, D/R set to 60%/100% Roll, Pitch & Yaw with 10% expo to deadband the center of the stick a little.

I find 60% more than enough for indoor flying and makes for longer flights as you aren't over-correcting.

I added a throttle curve to flatten out the area under 40% throttle (i think my jr 9503 has 6 points) so that it "pops" a bit more as I swing the throttle over the mid-way point - this also made touch and go landings easier as the throttle was smoother on the bottom end.

You said 150% and my DX6i only goes to 125%.

The DX8 goes to 150%. But use whatever you can get... the point is to use maxed out travels to make abrupt aerobatics like flips easier. And again, it doesn't affect how the mQX flies. Just how it responds to a given stick movement.

Just tried the "Mini-mQX" mod.... motors and booms from the Walkera Ladybird. Like others, I just cut the connectors off the motor wires, stripped and tinned the wires, and pushed them into the mQX board connectors. A neater way to go would be to get four of the two pin male connectors used for the mQX motors. Their pins will fit the Ladybird motor connectors and essentially act as a double male adapter. Other than that, the "conversion" was dead easy.... just plug the booms in and go fly

Using a 300mAH NanoTech battery from my mCPX, it flies OK indoors and I get 7 minutes to BEC cutoff (I set the timer to 5 minutes). I find it hovers at a somewhat higher throttle setting than the stock mQX. That means it is a bit less able to correct for wind gusts outdoors (because it runs out of throttle range sooner). It flies OK in wind, but you tend to hit 100% throttle easier, with the resulting instability. Maybe a 200mAH cell would be lighter and let it hover closer to 50% throttle.

I find that outdoors in wind it also occasionally has a bit of a wobble.... very subtle, but there. As if the gyros were set up to anticipate a slower and higher mass airframe.

So, it will be a fun little thing indoors, but outdoors I think I'll stick to the stock mQX.
