Futaba FF7 & CCPM ?

Is the Futaba FF7 radio CCPM capable ?
I have noticed 2 different helicopter modes:
Heli1 and Heli2. What are they for (the manual only says that the Heli2 mode uses 2 servos)?

Thanks.

regards

I contacted Futaba regarding my FP-T7UHF Super (which I believe is the same as the FF7) about the HELI1 and HELI2 modes as well. I did not get a clear answer about the difference between HELI1&2, but they did say that it is NOT CCPM capable. So I will also need to buy another transmitter.

Thanks for your comments guys. My transmitter is an FP-T7UPS. The only difference that I could notice in the manual between heli1 and heli2 is that heli2 is a "2 servo mode" while heli1 is "1 servo mode" (!). But 1 or 2 servos to do what ???

injunnut here is an explanation of CCPM and I think that the FF8 is CCPM capable.
CCPM : "Cyclic-Collective-Pitch-Mixing, CCPM mounts the servo's pushrods directly to the swash plate at 120 degree increments, like an equilateral triangle. With these three servo's the swash plate can be tilted in any direction, and when they all mo ve in the same direction the swash plate can be raised and lowered. All the mixing is done electronically by the transmitter, which means you MUST have a ccpm compatible transmitter " found on http://www.net-express.com/nexus/glossary.html

Huey, you can go back and edit your postings. Just put your cursor on the little gizmo at top of page that looks like a hand held water sprinkler (3rd gizmo over to the right) and click. This will bring up your post so you can change it any way you like or even delete it. I wish you would go back and correct the URL so when anyone clicks it, then it will work!

I used to fly a FF7 (Super 7 in the USA), and here is what I know...

1 servo mode is for use when a single servo is used to control collective, ala Raptor, Hawk, Ergo 60 Sport, etc.

2 servo mode is for use when two servos are used for collective/cyclic (and a third servo for the othre cyclic channel). This is sort of a pseudo-CCPM, but is NOT the 120 degree CCPM that is becoming popular in the USA.

If you want to user 120 degree CCPM, your options are to replace your radio, OR purchase a nifty little gadget from Quick UK that performs the electronic mixing to convert your radio's standard 3 servo (aileron/elevator/collective) output to 120 degree or 90 degree CCPM. Mine cost me somewhere around $65.

I hope this helps.

greetings, i had an eco and a futaba 7 heli super radio years ago. the radio will mix channel 2 and 6 so it will work at a hover. as soon as you start adding collective you will run out of pitch/roll. so it will do it, but not right. the heli 1 and 2 servos are for say an x cell, use one servo if you have a sliding servo for collective, and use 2 servos for roll and collective together.
