Radio - Servo - Gyro - Gov - Batt > Stylus Channel Re-Assignment

I'm trying to setup a Stylus on a stock Blade CP 4-in-1 but have run into a problem with the channel assignments. CH3 on the 4-in-1 is for throttle while CH3 on the Stylus is for the front servo in the CP3(F) mode. I don't think a C-Mix will work because it does't actually re-assign the channel.

Do I need to crack the case on the 4-in-1 and try to re-wire the berg connectors to match up to the Stylus assignments?

Thoughts?

Thanks, Doug

Right, that would be my guess and suggestion. Swap the RX wires to match the TX channel assignments.

That's what I was affraid of... I'll need to pull the case apart, but I think the modules are stacked off the Berg headers so it might get a little tricky.

Happily the modification worked. I opened the case on the stock 4-in-1, removed the berg headers in the wrong locations, and soldered six (6) wires to their new pin assignments. Works like a charm...

Now the only problem is in setting up my CCPM. The swash moves correct for everything but the pitch. For some reason, up is down and down is up...

Make sure you are in either CP3F or CP3B in the swash menu, make sure that the channels are properly attached to the swashplate per the drawings in the 96813 CCPM addendum. Once this is done try reversing the individual channels one at a time and then in combination. I'm sure you will get it.

Thanks TM,

Per the addendum, I selected the CP3F and reversed channels 2, 3 and 6 as needed to get the proper swashplate movements. It wasn't until after I had the right stick dialled in that I noticed the left stick or pitch is reversed. According to the 4-in-1, the throttle response appears to be correct (motor disconnected). I'll take a look at the CP3B configuration and try to verify the pitch again this evening.

Thanks again,

Also make sure you have the aileron and pitch servos connected to the right channels and just swap them around in their mounts if not.. I was running a reversed pitch curve for awhile because the eCCPM servo layout was pictured wrong in my Stylus manual.

I now have the aileron servo on the left of the heli and pitch servo on the right.

I'm still a little confused on our eCCPM setup. According to the Airtronics Addendum, we should be running swash layout CP3(F) with servo 2 (Aileron) to the left, servo 6 (Pitch) to the right, and servo 3 (Elevator) to the front as facing the helicopter with the tail pointing away. I could not get that configuration to work...

In mode CP3(B), it seems that everthing works correctly, but it's 180° out for what the picture of the swashplate looks like. The B-Mode has the elevator servo (#3) pointing towards the boom which is obviously not correct for the Blade CP, but regardless, it seems to work correctly. The Aileron servo (#2) is to the right and Pitch servo (#6) is to the left as facing the helicopter with the boom pointing away.

Did I miss something in the setup or are we good to go if the swash movements are correct when moving the sticks regardless of the addendum drawings? The ESC and T/R are working correctly as configured as well.

Another strange thing is with the pitch curve, but I'll work on that tomorrow night. I can understand why people say eCCPM is definitely a different beast!

Thanks for the help guys...

Yeah I think you need to swap the aileron and pitch servos.. Aileron on left with nose pointed away from you, pitch on the right. (Aileron on right pitch on left with tail pointed away). That's how I have it arranged on my hornet for everything to work out right.

If the CCPM scheme is working correctly it really doesn't matter if you use CP3F or B. If the motion is correct with stick movement, the pitch curves will be working correctly.

There are certain combinations of reversing switches that make it all come together.

Well the CP3(F) servo layout in my Stylus manual is definitely wrong. It shows channel 6 on the left side of the heli and channel 2 on the right which just wouldn't work right for me no matter what and so I was running a reversed pitch curve until I figured that out.

I swapped channel 6 to the right side and channel 2 to the left and now everything works as it should including a normal pitch curve.

Did the hovering pitch knob work in reverse?

I don't hover at half-stick so I never tried it, or even thought to.

I don't hover at half stick either but that's the clue as to whether or not you have the CCPM setup correct. If the HVP knob works so that more pitch is with a clockwise rotation of the knob, the pitch curve will be correct.

Hmm.. I kinda assumed it was tied in with the pitch curve so that which ever way the curve functioned then so did the hover trim. I always have it inhibited and never use it though.

When ATX did the first CCPM software for the I1000 we used a software function called Pawl Angle. It essentially allowed you to reverse, rotate and select the direction and number of CCPM servos driving the swasplate. Sanwa used this model to create the latest iteration of the software when they did the RD series. It has migrated to the last helicard revision for the Stylus. The one constant that some of us found was the fact that when you had everything working correctly, the HVP knob would track correctly and increase the pitch in CCPM just like it would on a normal collective machine.
