I need help with this also. Everything is moving correctly except for the collective pitch diag part. On my Mini titan its weird, when I move my stick up the swash moves down increasing pitch, I think its the opposite fort he trex 450.

because If i set it up where the swash moves up when i move my collective up its wrong. also i checked to see if the corrections were moving in the right way and it is.

Hi ... As mentioned in the manual You might have to trade servo one and two on the rc-module for correct swash moves, due to certain swash types having the opposite direction for pitch-moves. Be sure to check the correct synchronicity also in the software tab "diagnosis" of the helicommand software (It's good to have if You're not doing so ;-)). If it does not match You will have swash and stick moving moving properly and diagnosis bar showing the other way round ... This MUST not be.

Best from Berlin,

Swop CH 1 and 2 on the rc-module. You do NOT need to reverse CHs in the Tx. Check everything on the diagnostic tab for correct movement.

Just reverse the pitch channel in your radio.

No .... as I said .... Do NOT reverse the pitch channel ... It will change the swash dir. but NOT the virtual dir. within the software integrated. Do not change TX.

I just got this sorted out on my MT, too. My manual didn't mention reversing the channels, but Captron verified that it is the thing to do and sent me the new manual. Here it is hot off the press:

Butters - there aren't that many MT guys flying the HC, so maybe we should keep this thread going to share the experience. What do you think?

I should have said "swapped" the channels. I switched the left and right servo connections on the RC module. My instructions said to plug the left servo into the 1st slot and the right servo into the 2nd slot. With that set up, everything seemed to work ok, but on the "Diagnose" screen, the collective display was backwards. One problem with that was that it inhibited autotrim.

I still haven't found a way to adjust the end-points of the individual servos to get rid of swash interaction. Before I installed the Helicommand, I had it almost perfect by adjusting the end-points in the transmitter. It's not a BIG deal, but it would be nice to still have that capability.

Here's how I mounted mine:



Where did you mount yours?

Back up back up back up!

Back up the HC unit itself with something... use elastic band or velcro.

Back up the wire that's plugged into the HC with tape or something.

Cover the PC port on the HC unit.

Back up the wires plugged into the HC module. They can easily pop out. Put tape over it or something.

Just looking out for you...

dleroi123,
I really like your mount idea, but as nooobs says get a velcro strap or zip-ty around it as insurance for it coming loose.
Think about, it is a rather large item with a flat face to be sitting in the downwash off your rotor plus there is vibration. At some point Murphy Law will come into play!
The connector has also been known to come loose. Cover your pc-link port with tape just to keep the dirt out of the inside of the HC module.

Nooobs and Seablade,

Thanks for the good advice. Here's the final solution:



The PC port, LED, and set switch openings are all covered.

Good job!

Not sure if you backed this up as well...


I wrapped it with electrical tape just in case they pop out.

see how the vertical piece of velcro is.
There are two ends that velcro together...(duh, I r smart!), undo the top one-the one that is coming down from the connector.
Leave the bottom end underneath the horizontal velcro strap and re-connect the top piece of the velcro to the bottom piece "over" the top of the horizontal piece.
This way the the vertical strap is also holding the horizontal strap in place to prevent it from sliding up or down and the horizontal strap is helping to hold the vertical strap in place
(You may want to lengthen the vertical strap so that there is still the same amount of surface engaging on the velcro hooks to make up for the surface area lost by putting over the top.)

butters149 - page 8 of the manual tells you exactly what that flashing green is

Thanks Noobs and Seablade.

Noobs - Yeah, I just haven't decide how I want to do that. I had a rubber band around the connectors and board, but didn't like it. Maybe tape is the way to go. Do you tape your receiver connections, too?

Seablade - good suggestions, but I took care of that. Both straps are attached to the back of the mounting plate and the two are Velcroed together in front, where you suggusted. Good job on the photo!

No not the receiver. It's secure enough. Just the HC module. Since it's an "open" connection the plugs don't have anything to "push against" to except against other plugs.
