![]() It's not the ratcheting strap that's causing the sticky throttle. It's the smooth strap against the smooth part of the gimbal that feels sticky.
The ratchet strap isn't engaged with the gimbal unless you tighten it down against it, and this mod has nothing to do with the ratcheting feature.

![]() A week later and my throttle is still perfectly smooth. I hope this mod lasts. My biggest concern is that it comes loose during flight and causes a crash.

![]() Just applied this mod to my DX9 and can only say the difference is amazing.
Was pretty much smooth before but WOW after doing this mod it is now buttery smooth. ![]() Many thanks to the OP. ![]()

![]() Same for me! I used the Plumbers tape teflon last night, and flew 4 flights today.
The cool thing is you can even tighten the strip down much more that what was being used before, and still be very smooth. The reason I ran mine so loose was to prevent the sticking feeling from a stop, and now I can fine tune using any resistance I want and still be good

![]() Have to say this mod is awesome so thanks to the OP for posting the idea.
![]() I have done this to my DX8 and DX9, the difference is amazing. I got a roll of teflon tape which has an adhesive backing, just cut to size then peel off the backing and it stuck fine to the metal strip after I degreased it .

![]() I can't find the exact listing, the seller I bought from had a choice of sizes but it was similar to this:
http://www.ebay.co.uk/itm/heat-vacuu...item3f36431dea I'm sure you could get it from eBay in the USA. Edit: Maybe this would be ok? http://www.ebay.co.uk/itm/PTFE-Teflo...item35d4be2f1a

![]() I've used PTFE tubing on tail CF pushrods and it's pretty stiff when shrunk. I'd be afraid that it wouldn't conform to the shape of the spring very well.

![]() I wish someone with the creativity and tools could produce a replacement spring made of a different (more slick) material.

![]() I've thought of this myself. In fact, I think just a strip of teflon, with just the right thickness/dimensions, and holes drilled for the screws would work great. I used to work for an industrial pump supply company, and we had teflon diaphragms that would probably be just right for this. I've been thinking of buying one and trying it out.

![]() I used the cheap teflon plumbers tape from Wal-Mart a few days ago and WOW, what a difference! Smooth as silk from top to bottom, regardless of how much tension I dial in! I'm going to try the "pressing cloth" mod tonight and see if it's any better. The plumbers tape is very flimsy and I don't think it'll hold up, long term. I bought some "Non-stick pressing sheet" from Joanne's. The brand name is Dritz, I believe. Will report back here this weekend.

![]() Another option I have discovered are teflon coated, reusable baking or "cookie" sheets
They are much easier to find in Walmart, etc cooking utensil section, vs the pressing sheets in my area. http://www.amazon.com/Regency-Reusab...ie+sheet+liner

![]() I actually got it done this evening. Man, is this an improvement! I was running the collective looser than I really liked it so it would be smooth. Now it's a little stiffer and still buttery smooth.
Here's what the spring looked like after the mod (but before attaching the adjustable end).

![]() Done the Teflon mod on my DX8 and 9, the difference I night and day.
Saying that, Spektrum needs to take a leaf out of Mikado's book, the collective stick on the new VController is way better than my modded DX radios. All the years Spektrum have been making these radios I think it's time they learnt how to make a simple smooth stick. ![]()

![]() That looks great Bum! I'm still using the plumbers tape with good results. Been busy flying, or just busy, and haven't got the pressing sheet installed yet. Should have it done before the weekend.
Is that fuel tubing holding the sheet in place? I used heat shrink on the plumbers tape and didn't run the screw through the end of the material. Will definitely do that next time. I think the tape is deteriorating and slipping some. |

![]() Yep, that's fuel tubing. I actually hadn't planned to run the screw through the sheet, but just as I was about to cut off the excess, I realized it would help keep the sheet in place.

![]() Hi guys, after buying a DX9 myself and not being overly happy with the sticky throttle I found this thread through google....thanks alot to the OP for the idea. A couple of us have tried the mod ourselves over on archeli with great success (see page 3 for pics) http://www.archeli.com.au/forums/sho...58#post1596858
Can highly recommend this mod, very quick and simple for a buttery smooth throttle! ![]()
