Idle up problems with futaba 6exhp

[sikorskys76]

When I have my radio in throttle hold and I put up the idle up switch to check my pitch the swashplate does not got into Idle up.It works in flight but not with thottle hold.

It worked before but i crashed yesterday and refixed it and now I have that problem.

Any ideas?

Throttle hold over rides all other flight modes.

Throttle hold over rides all other flight modes.

I set up my throttle hold on my futaba 7CHP and a 450 SE V2. When I turn on throttle hold, it cuts the motor and moved the swash down all the way, therefore giving it full neg pitch...is this a good idea ? Seems to me that giving it full neg pitch is a bad idea when heading toward the gound :-(


Lucky me, I have not had to use it yet, but I am wondering if this is going to make my heli hit harder with the energy that is still stored in the blades while full neg pitch is applied.

Its odd because it was working before!!

Negative pitch is what keeps the blades spun up when doing an autorotation. When you learn how to auto rotate, you will understand why the negative pitch is needed in throttle hold at full low stick.

You need to set the pitch curve in TH also. And if you dump the stick first, then TH will give full negative. But you can raise the stick and get any pitch you want.

The idea being, GET OUT OF THE HABIT OF DUMPING THE STICK.

When you flip to throttle hold and the swashplate goes to full negative pitch what position is your collective control in? If it is not in the full down position then I'd recomment you look at your curves for TH mode.

I have the same radio and as BaracudaHockey said above the radio reverts to the normal mode pitch curve when throttle hold is engaged (regardless of the flight mode switch positon).

Easiest way I found to setup/check the pitch curve is to use another model memory and set your 'idle up' pitch values in the normal mode then you can use the throttle hold switch to check your pitch curve
