Don't get me wrong ,,a third mix is not really needed and with a Gov I use no Mixing on my Raptor 50. Just wondering if anything has changed. Either way it would not sway me not to buy an Airtronics,,It's a Great radio and proven. If the 2.4 version works well as I'm sure it will it will be a superb radio especially for the price.

Setup is everything, All my heli's can fly far better than I can pilot them

I'm wondering if the 3 & 4 channel 2.4 gHz rx's for ATX's ground systems will work with the RDS8000, and if any or all of 'em will work with the upcoming Stylus 2.4 gHz module.

The biggest CCPM limitation of the RD8000/RDS8000 are that you have no EPAs for the three swash channels. The EPAs for the aileron, elevator, and pitch channels become the equivalent of Swash Mix on JR and Swash AFR on Futaba.

You also have no easy way to reverse a function as you do by changing the sign of a Swash Mix/AFR value. Instead, you have to play around the swash type, servo reversing, and left/right channels to get all three servos going the way you need them to. This is the same on the Stylus.

Also, one should read up on the failsafe implementation on the RDS8000; it's rather odd and, dare I say, perhaps not so safe.

This is my main concern, so using NO subtrim and getting the swash PERFECT at mid stick is going to be the key I assume.

This isn't such a big deal, but will take a bit more time to set up.

This is kind a strange, I wonder why they chose to make it that way?

Endpoints
Those of you using the Hitec digital programmable servos will have no issue whatsoever. You can use the Hitec programmer to tweak the servo center and individual endpoint in both directions. I wish I had this option right now, but I am using the cyclock as listed below.

I believe programmable servos WILL be the wave of the future from most manufacturers within the next year. Spektrum has announced this with their low end micros, Hitec is doing it already and are expanding their line, and I have heard some buzzing of others considering the same.

Also, using the CSM cyclock, V-bar, Pro-bar and other eccpm electronics have these features built into them as well.

Lets remember that the RDS8000 is the first offering from Airtronics in this arena. I am certain there is more to come soon with better features. Airtronics wants to make an impact on the helicopter sector. As we provide feedback and details about our needs, I bet they listen and take action.

The endpoint adjustments are not critical to beginning pilots. Hardcore 3D guys will definately need this, but lets take an honest look at who this RDS8000 is marketed to. Remember, there is another radio for the advanced pilots coming down line. Plus, there will be a module for the Stylus.

I would respectfully disagree. Beginner pilots do not need to have extra things to worry about like requiring extra cyclic inputs to counteract unintended swash movements due to a less than correct CCPM setup.

Don't get me wrong, I'm not saying the lack of endpoints adjustments is a deal breaker, but something to keep in mind because sometimes you really need them.

I can accept your challenge, to a point. There are guys in my club that have never progressed past simple tail in hovering the entire 15 years they have flown helicopters. I cannot see how a little endpoint interaction could possibly hinder their flying if they have properly centered the servo horns, used subtrim at center, and have proper linkage geometry. They are never flying at the extremes of the pitch range where this interaction is found. Other beginners may not remain at this skill level for 15 years, but I have 4 guys in my club that have been flying for three years and are still in that same nitche.

However, I have seen some beginners go from first hover to 3D flying in their first year. I agree 100% that these beginners would be hindered by endpoint interactions. They would be forced to add uncessary corrections, which could create bad habits in their muscle memory flying skills.

FWIW, this answer was posted on the Airtronics.net forum:
The 2.4gHZ ground and air systems are different and are not compatible. The intention is for the RDS8000 receiver to work with the stylus 2.4gHZ module but since it is not done yet, we don't know for sure if that is going to be possible.
