Finishing up the Turbinator set up, my Boomer is next, fallowed by the Reaction, they all get a 12 chl receiver, even if only 10 chl are needed, I like the 12 chl antennas better, DSM10 with a magnetic on/off switch, just waiting on those 900mhzNG back up receivers to complete my install for all of them, two batts, may try the wireless switches later, I got one but, will try it later.

Having lots of fun with the switch of brands, love the Jeti flexibility.

If I only had more free time at the moment.

Carlos,

A nice safety thing when it comes to gyros that I like to use is a velcro strap to hold them down, on top of however you are attaching them.

Having a gyro come loose at certain portions of the flight, when you can not turn it off fast enough, will kill an airplane. Imagine a fast low pass or on final.....

Added the Velcro strap to the receiver and completed the assist set up by making the gain knob a digital trim, it can now be flown to adjust.
Moving on to the Boomer.

Sadly, the Assist gyro is getting a lot of reports of acoustic interference from jet engines. You should ground test it before flying. With the engine running, switch the gyro on, turn up the gain, then slowly increase throttle one click at a time. Watch the control surfaces very closely for any signs of shimmering or larger glitches.

I will do that check on all my assist installs and will report back.

Thank you Harry.

These typically happens at a certain RPM not the entire range. By doing the test Harry suggests you will find the throttle setting.

BTW. The velcro strap may Exacerbate the problem. If the surface that you mounted the Rx to is a smooth hard material the foam tape will never loose its grip. I have never seen a gyro come loose from a 3D heli Install.

I was going to say...Velcro and Velcro strap is not a good idea......should used the sticky double side foam pad it come with.

Excellent Carlos..,!!! Great job, fantastic radio customization.! I definitely would like to do something similar. I just bought also a DS-12 coming from FrSky HORUS, and spektrum and JR XG11. Surely this jeti is the lightest and better so far.
This thread is awesome..! Makes me hooked to RCU. I was more inclined to RCGroups and FlyingGiants, because I thought that they were better, but the content of this thread is much better and teaching than the others. Thanks for nurturing it.
I did exactly the same mods you did. 3D wheel, switches changed, etc. just waiting for ZB/Esprit, to bring the anodized aluminum sliders to sale, to buy a pair. I have a black DS-12 so, in red those pair of sliders would look sick!..
un abrazo fuerte tocayo..!!

If the assist gyro is suffering from this type of interference, then it doesn’t belong on a jet. I have 3 assists and they are on non turbine airplanes. And I have also heard this rumor. And why it’s so important to have an “off” setting if one is going to try to use one on a turbine.

And sorry to disagree with the gents above, but the risk of a gyro coming loose is too great to not strap it down. It may not have to be tight, but an extra layer of protection NEVER hurts.

Pretty much every jet is more expensive than a 3D heli, the helo’s have nice and clean carbon fiber to stick to and the helos just don’t go as fast as jets.

Edit: In all fairness, I doubt any airframe gets more "G" abuse than those 3D helis. The stuff those pilots can do are amazing!

maybe with the tray that esprit/Zb sells, and the rubber o ring and this tray bolted to the wood board.

I think he was mentioning the 3D heli because of the insanely violent (maybe I should say high G) maneuvers they put them through and the RX still doesn’t come loose with just the tape.

I only have 1 assist installed but I have two more in the bench waiting to go in. The one I have installed is using the 3D printed mount that esprit sells. It’s installed in a turbine and no issues so far with it after over 50 flights.

Carlos, thank you for the nice words, if you would like some of the tape I used on my radio, send a pm and I will mail you 12" of it for your radio.

This thread is an international team effort, we have the best of the best posting on this thread, many thanks to them.

Ahh! Miami, haven't been there in years, will have to visit the family soon.

As Raffy suggested, secured not tight.

And sorry to disagree with the gents above, but the risk of a gyro coming loose is too great to not strap it down. It may not have to be tight, but an extra layer of protection NEVER hurts.

100% agree with Daniel, double side tape is the way to go.

The suggested step to check for acoustics interferince is a must do, I think this check becomes crucial as the bearings get loose and this check should be performed a few times a year.

Thanks a lot for your offer. My radio already have it in place. Thanks. Please show pictures of your jet once you manage to set it up.

Do you something specific that you would like to see from the jet set up ( crow, on and off, how to make sure the servos are going the right direction when the gyro is correcting.

Here you will find a few things that yourJeti radio can do for you, pick the ones that you think you can use.

If the double side tape that is holding the receiver to the floor doesn't do the trick then, I will get me a receiver holder with the O ring and will give it a go again.

As much as possible, you should only use the double sided tape to mount a gyro. This is in the instructions of every brand of gyro, not just Assist. Do not use hard mounts, clips, velcro straps etc. Only use the foam tape. There is a reason that every brand of gyro comes with foam tape, take the hint! If you attach it to a clean smooth surface (not bare wood) it doesn't come off.

If you have to mount the assist to a balsa surface cut a piece of 1/16” ply To the size needed and prepare the surface using thin CA glue. I usually coat it two - three times letting it dry between applications. The goal is to create a smooth glass like surface.
then glue the ply plate to the airframe and its ready for the assist to be mounted.
