I have an Eco 8 and a Raptor 30V2 both using the Gyro menu to set the gain on CSM560's but they both seem to work so differently. On the Raptor I can set the menu % to maximum in both directions and still don't get any wag in HH or Rate which I'm inclined to think means I'm not getting enough gain, tail holds and feels locked to me (I'm a beginner) but it is not possible to get it to wag at all but on the Eco 8 I'm only using about 80% and 20% before it starts to wag. I've checked the settings are the same on the 2 helis in the radio and I'm starting to think that maybe the menu only really works correctly with JR gyros.

I used to use the Gear channel but I now use that for the GV-1 on the Rappy and wanted the two helis to use the same switching. Any ideas or pointers?

i have my Gyro gain (401) plugged into the Gear channel and use the ATV to set my gain. The Gyro Sens menu needs to have the gyro plugged into Aux2, but a number of people i fly with have found the gyro sens doesn't work as they'd expect so now use the gear channel for hh/normal - mostly people using futaba gyros on JR radio too!

I also use a GV1 which i have on the aux2 switch for on/off, leaving head hold on/off on the gear switch.

Smoothound,

You have to remeber that the 2 models are completely different and are therefore running different tail rotor speeds, pitch, amount of throw, possibly different tail servos?

I used to have an ECO8 and it would wag really easily with the gyro I had in it. I think the ECO8 may have a fairly sensitive tail setup which is why you are finding it easier to "overgain" than the raptor.

The gyro menu in the PCM9x is just a pretty front screen for the channel travel settings effectively. Instead of having to set your figures to things like -73% and +22% it gives you a 0% to 100% range. However these figures normally only make sense on JR gyros and different gyro manufacturers require different settings. This will not stop them working with the JR gyro menu page.

It may be an idea for starters until you are more comfortable with the radio and model setups to not use the gyro menu and instead use the ATV's as per the 560 instructions. Then when you get a good feel for the gyro setup to try and mimic it on the gyro page.

Hope this helps

Mark

I gathered something along those lines about the Eco 8 but I still find it odd that the Raptor works OK with the settings on maximum and never shows a hint of wag. Especially when you consider I built it up quite quickly and didn't spend ages balancing everything. There are no visible vibes but I would've expected that running the gain at 0% and 100% would've had the Rappy wagging which was possible using the gear channel at about 85-90%. Any ideas?

You really cant compare between 2 different models, You cant get the tail rotor to wag ? try moving the linkage a hole further out on the servo horn, more than likely it will start to wag and the gain will have to be turned down.
