TREX 500 Tail-RevoMix on AR7200BX

[Dan22]

AR7200BX V3
When i spool up my Trex 500, even in soft start i am getting tail kick and it will only sit still when it gets light on the skids.
Am i right in thinking i need to adjust point F Tail-RevoMix in the parameter menu.
I have got the heli flying nice now and am confident that the tail gain is about where it needs to be. When i do flips or, if i forward flip out of inverted back to right side up and give it too much torque the tail kicks out slightly. So it seems to me that the tail is finding it hard to deal with sudden bursts of torque and wondered if adjusting point F would do the trick?
It would be good to know what other people have their RevoMix set at.

Thanks,
Dan.

try point d page 68

makes the tail stiffer and quicker to react also where is the ball on your tail servo arm sounds like it may be to close to the center try moving it out anther hole (will make it quicker) if you move it anther hole out please remember to set up end points again

I researched parameter F when i set mine up, a lot of people dont use it. mines is set too purple/off. Have you tried changing parameter D up or increasing pot 3 a click?

if you increase parameter D you may need to set your gain again in the tx.

[aparkin]

no you don't if you read it it say set TX gain until it start to wobble then move it back a point are 3 so it stops then change bx gain my tail did kick out until i moved the ball out on my servo arm set up TX gain then beastx gain then fin tuned with pot to feel the way you want it to feel hard are soft

[Dan22]

I have lowered parameter D as i had too much bounce back when stopping, i then increased the gain in my TX, the tail kick is minimal, but its whilst spooling up i would really like it to stay put. By the way, i am taking off on concrete, when it's on grass it hold better, in fact i think it used to do the same when flybarred so maybe the point made about the ball on the servo arm could cure it.

Thanks,

also if its mainly spool up have you got soft start turned on and have you got any landing skid nuts fitted Landing Skid Nut H50052A / align trex 500 / Align T-Rex Spares - ALIGN-TREX.co.uk RC Model Helicopter Specialists in ALIGN, E-Flight, Blade, Goblin, Synergy, ALeeS, Outrage, ELY-Q the rubber 1s work best on concrete

but def set parameter d to default move servo ball out a hole set up end points test fly set gyro gain on TX then i moved pram d to high flashing blue test fly then move pot to adjust how sharp are soft you like you tail to work

please step in if some1 nos a better way but it worked for me my tail did a full 180 degree in high winds while flipping over now its solid

Yep, got some of them rubbers on, TBH it could be the Overlander ESC i have, the soft start isn't very soft and i cant find a manual on it.
Thinking about getting an Align or Castle with a governor mode as well.
Meanwhile i will take your advise and try what you did.

Thanks,
Dan.

TREX 500 Tail-RevoMix on AR7200BX

Haven't had chance to fly it since Saturday mate, but will give a bash at the weekend and let you know.
I definitely think a new esc with a true soft start will solve the spooling up problem.
