Collective Pitch / Throttle

[patrickvdb]

Hello Guys,

I'm new to the helicopter R/C world and I'm just assembling my first one.
Don't worry I won't be flying it shortly, because I will do my mandatories hours on the Simulator first... However I've got to assemble my toy now, that's also part of the fun.
My friend, who is a heli expert is on holidays for the moment, so I can't hassle him with my stupid questions at this time :)

The systems is completly assembled (even rather good I think) but now the calibrations and stuff are coming.

I have a rather stupid question about the throttle/collective:

The 2 sticks on the transmitter should normally be centered when you want to start to fly right?
Now isn't it so that my heli should first powerup to full RPM and once the rotor have the correct speed, I should increase the collective pitch, which should enable lift... Or am I totally missing out here?

The problem I have is that the speed controller of the motor only starts the motor when I move the throttle stick completly down (like an airplane) and then move it up which will increase the RPM of the motor (like an airplane)... but that should not be the point in Heli or am I completly wrong here?????
Shouldn't the motor have a steady rpm... the stick in the center, moving the stick forward should change the collective so I get lift, moving the stick downward should decrease the collective so the heli descends?
But this doesn't work for me because the motor acts like it should do whan used in a model airplane.

And if it would work, how do I switch off the motor?

I have configured the ESC for heli operation, but it does change anything.

The flight sim doesn't help, because the engine is always on.

For the rest, everything is setup and calibrated correctly (I think), it's the only problem to make it operational I have up to now.

Could somebody please explain me these real basics?

My setup:

Heli: Thunder Tiger Titan mini E325
Speed control: Ace RC BLC-40
Transmitter : Graupner MC-12 (got to change that one)
Gyro : Futaba GY401

Any help would be great.

Thanks

Watch the Finless T-Rex videos (http://www.helifreak.com/showthread.php?t=11373), particularly "Pitch and Throttle Curves 101". It'll tell you everything you need to know about how the throttle and pitch should be set up in each flight mode. The rest of the videos will tell you just about everything else about general setup of a CP heli.

Definitely. Watch the videos, particularly the CCPM1 and CCPM2 videos. They will explain in great detail the hows and whys of a collective pitch heli.

Get rid of the plastic mixing levers both upper and lower and get metal ones. I own one of those so trust me on this one.

Hello, thanks...

These videos are definitly very worthwhile.
Very good that this exists, congrats to the creator.

Since, I'm new to heli and this forum, I didn't catch them yet, but now I have found them and can't wait for this evening to go through them

thanks

PS: Surely you'll here from me again :wink:

I wanted to point out here this this is for sure... NO. Only the right stick (in mode2) should be centered when you're ready to start to fly.

If I read this right anyhow. Your throttle/pitch stick (left one in mode 2) should be at the bottom, all the way down when you get ready to apply power to the heli.
