Admiral RX600SP 6-channel DSMX with Stability Plus Gyro

[xviper]

Has anyone encountered any problems with the gyro not initializing after reversing the gear switch? I have two of these mounted in 70mm Hawk and Hornets. I recently switched all of my aircraft gear positions to all match but after doing so, the gyro will not initialize. Works fine in gyro off mode. All I did was change the gear switch from gear up-down switch position to gear up-up switch position. Went back to the original setting and it works fine. It's not a huge deal, but I would much rather have the switch setup the same for all of my planes and the up=up, down=down makes much more sense.

Thanks in advance! Btw, I love the receiver/gyro! Easy to program and get dialed in as far as gains. Have not tried one in any of my larger jets yet but have one on standby for the 8s F4 once I get it trimmed out.

Look at the monitor and see what the end point numbers (for the gear channel) are for when it used to work to when you reversed it and it no longer works. Make sure the end point values are the same but at opposite ends of the gear switch travel. It should read something like -100 to +100. When you reverse it, it should be the opposite.

Thanks for the reply ... my problem is that the receiver is going to be mounted into the fuselage of a low wing mounted aircraft. Unfortunately I have no access to to the area through the canopy. I really don't want to get into a non standard installation, and perhaps I can work something out by pre-mounting the receiver normally, and installing it on rails ... just a thought. Thanks again.

Although it is recommended to mount this RX right side up, it can be mounted inverted. You must re-calibrate the orientation of the gyro. It also has dip switches that you can use to reverse the gyro response direction. Do all of this after installation and the product should work. It is up to you to check all control surface response and all gyro direction response before you fly it.

Mounting the RX inverted reverses the yaw and pitch. (if you kept it pointed the same way forward)

Generally to avoid confusing the gyros, mount it upright with the correct end pointed forward.

RX600 SP Installation question ... I will be mounting my receiver in an inverted position position. AM I going to be ok with the standard basic installation.
Thank you.

Hello Pilot I am trying to set up a RX600 SP in the new L 39 it has the blue control box with a DX18. The receiver works with the original function but the Gyro does not turn on I have followed all the instructions on the videos that motion RC has posted any help would be highly appreciated thank you.

Thank you for the recommendation. Luckily I haven't tried to fly the Wing yet. I will program the radio with the wing as normal instead of elevon and see how the control surfaces respond to that. By reversing some channels I got the plane to respond to my inputs correctly but I was suspicious that something was not right with this approach. especially when the rudder on the radio stick was moving an aileron. Thanks to both Tom and Xviper. If I still have some issues I will get back to you.

[xviper]

Thanks for responding. I agree with your comments.I think the throws are also reduced because the radio is programmed for an elevon type wing which electronically mixes the elevator and ailerons at 50% for each. Weather permitting I will be trying out the delta wing on Monday with this receiver.

I'm glad Tom caught this. There should be a warning on all stabilizers "DO NOT program wing type mix in the radio". Keep it at "NORMAL" wing (1 AIL) and normal tail. You should have also noticed that when you move the stick, the control surfaces will not only have diminished throws, but they won't work correctly either. In most cases when mixing is done in the radio before it goes into a stab, only one elevon will move with stick. The other will likely do something goofy or nothing at all. As Tom said, don't fly this thing till you confirm that elevator and aileron inputs make the control surfaces move in the correct directions and that all stabilizer control responds in the correct direction when you move the whole plane in each axis. If stab response is reversed, the thing will roll upside down or do a crazy loop (inside or outside loop) or both.

[Tom]

If you have the radio programmed for Elevon, this is a big problem and likely leading to the diminished throws you see. You want the mix to take place in the gyro, not the radio. The radio should be set to "normal" for wing type and the gyro dip switches should be set to "delta". Please don't fly it the way you have it setup as it will more than likely lead to a crash. Here is the manual for the gyro: https://cdn.shopify.com/s/files/1/10...P_Receiver.pdf .

Hi,
I have installed my first RX600 SP into a delta wing Sky Fun plane.No problems with binding and all control surfaces work fine with one exception. I have programmed Dual Rates into my DX6e radio of 70% & 100% but even at 100% the maximum travel for the ailerons/elevator is 80% Even changing the maximum rate to 105% does not result in a 100% servo movement. I am using default Mode 1 on the receiver and the Recovery is working. Does this have something to do with the receiver or something I failed to do when programming my transmitter?

I can't speak directly to this receiver but in all my other stabilizer devices, throws are diminished when the signal goes through the stab. I use max rates and it seems to make no difference. As soon as I turn the stab off, I get all my throws. On the bench, I can actually see less travel when going to mid and low rates but in the air, the difference between rates is minimal. The stabs I've been using seem to dumb down the throws, unless I use "3D" mode, which not all stabs have. In "3D" mode, the throws can be achieved.

It is a manual process of reversing the direction of travel of the individual channels but even then I think it will only work in gyro mode, not recovery mode. I'll do some testing and remove that from the manual if it proves to be the case. One of my main goals with this gyro was ease of use. For this reason, unlike most gyros, it does not ever need calibration. As long as you install it properly in the airplane, it just works. for that reason, I'm not sure inverted recovery mode will function even if you reverse the dip switches (as needed) for recovery direction on each channel.

I've been buying these RX600SP's like candy and have them flying great in FMS Yak-54, Freewing 64 mm F-8, Freewing F-4, and Freewing F-86. I'd like to install one in a 70mm Freewing F-16, and the easiest installation would be to install it inverted. The "Quick Start Guide for Admiral RX600SP Receiver" states "We highly recommend installation of the unit in the upright position. If an inverted installation is chosen, you MUST recalibrate the orientation of the gyro. This must be done in recovery mode followed by normal stabilization mode." I've watched all of the videos and have not see any guidance on recalibrating the orientation of the gyro - may I get instructions?

I do see a difference in stabilizers now that I have several different makes of them. This stabilizer may not provide the high speed flutter as noted in others when gains are set too high but rather a "hunting motion". This was also noted on one of my latest test flights when the elevator gains were set all the way up just for experiment.....as usual fly - observe - land - adjust - fly observe - land ...repeat until you get it like you want it

Yeah, wish I made the reciever accessable without removing the wing...:Loser:
it was merely ‘hunting’ kinda like a poorly adjusted auto pilot on the full sized birds.
It’s a fun airplane because it requires you do everything for a turn, climb descent and all else with regard to rudder and elevator in turns. Can be a handful if you get sloppy or overcontrol. So dang it is fun just practicing a traffic pattern and touch and go and for now only low rates make a flight look respectable, it it leads you to anticipate proper input with power, pitch or directional changes so it looks smooth. She does fly straight and level hands off in calm wind and that is pretty much all I fly it in.:Whew:

I did try the Admiral RX600SP in flight and for the most part it worked quite well. Took a little while longer to get it smoothed out and fine tune the trim, was also doing some gentle pitching so I have turn down the gain a bit. Everything in the lateral and directional axis worked nicely.

[F22trainer]

Thanks pilot Ryan - I finally got around to swapping the Admiral RX600SP into my first ‘Old kit - New Tech build, the L-4 Piper Cub.
Since I recently upgraded to the DX6, I had no problems getting it set up, Thanks to the videos. Wanted it set up in Combo C for reasons you would expect. The plane already flies good, but really like the damping effects from stabilization and didn’t really need a recovery mode.
I will try it out tomorrow morning and let ya know how this little gal does.

[TwistedGrin]

I have noted that mine did the same thing once....but observed that during my battery hook up I had several failed solid Deans connector hook up whereas ...when hooking up the battery the RX was cycled rapidly several times and the stabilizer would not engage at final. Unplug the battery and wait a second or two...then make a clean positive battery connection. All good and normal stabilizer is present. Perhaps this could be a similar scenario??
