Futaba cgy760r and Vario Benzin 4-blade mechanics question
Hello all,

Anybody flying a cgy760r with a 4-blade set of Vario mechanics? Specifically in a 4 servo H4-00 configuration (AIL, PIT and an ELE and ELE2)? Radio is the 32MZ. I'm new to 4-blade setups but have lots of experience with these mechanics and MZ's in general.

I've got the cgy760r in my Kraken 580 and I liked it so much I decided to choose it for my Bell 412 4-blade project. I'm flying the project in pod and boom first with Benzin mechs with 4 servo 90 deg. CCPM. The 704/30 heads swash driver doesn't allow for mechanical phasing but I've flown the mechanics with no gyro briefly a couple of years ago with AIL-ELE and ELE-AIL cross mixing to get the desired swash movement.

As I'm trying to set up the cgy, it raises two questions:

1. Can you I not set a pitch curve in the radio to limit total pitch or does the cgy want to see a 0-100 linear pitch curve in the radio and force use of the SWH Basic swash and pitch throw options on page 3/5 of that sub-menu? I need significant reduction in pitch with the current setup with throws at 100 all around and using the pitch rate option requires me to take it down to 8% (from 50% default) to get what I want - around -2.5 to + 8.5 or thereabouts.

2. I suspect I want to turn off the AIL/ELE and ELE/AIL 100/100 cross mixing I used during my brief test flights and have the CGY handle it. Is that the course I should take? If so, looking through the menu options, the manual on the SWH Detail menu says that AIL-ELE and AIL-ELE2 mixing is ONLY available for H4-45 (which means at a minimum a new swash plate and complete re-working of my mechanics) and that ELE-AIL mixing is NOT available on H4-00. The manual does, however, detail a Swash Rotation option that might be what I’m looking for. Is it?

Sorry for the length of the question, but Google doesn't seem to work and I'm starting to think I'm the only one using this gyro on anything but 3D machines!

Thanks!

Mike

Go to FUTABA USAs website and look up Team Ambassador Dr Ben (he is here too).. he can help.

I have a 760 in my Vario Bell 206 Jet Ranger.. (two blades)
