Where the heck does the heat Shrink tubing go when installing the tail pushrod guides? My instuctions just say "Install heatshrink tubing"

the heat shrink tubing goes on the tail carbon push rod. It's used to help prevent the carbon rod from wearing down where it contacts the tail rod guides.

Thats all yours says Really?
My Aurora manual says, "Install the heat-shrink tubing and once you know where the pushrod guides will be and shrink them using a heat gun."
For what its worth, though, my heat shrink (measured from the center of the heat shrink) ended up being 6 1/2" from the rear end of the pushrod, and 9" from the front of the pushrod. My pushrod guides worked out pretty good in those locations.

Andrew, I'm pretty sure this is not just regular heat shrink. It's like a teflon shrink, and its purpose is to minimize friction between the pushrod guides.

who cares what kind of heat shrink it is.. it works doesn't it.

PSSSST!!!!!
NEWS FLASH!!!!!!
Reduced wear = reduced friction therefore reduced friction = reduced wear

You guys are great. Thank you very much.
Chevy and spoolking need a dance off to settle this :)

LOL Capi!
Can't we both be right?
We both have valid points, and you can't deny either of them.
A smooth tail is paramount.
Arbitration makes for poor entertainment.

What's the trick to getting the heat shrink teflon non friction/wear tubing onto the carbon tube?

Andrew: I noticed that you fly several YS 91sr's with the MP5 pipe. I would be interested in knowing your needle setting as compared to my 91sr with the Hatori pipe. I am currently running original factory settings and she works just great. When I try to lean her out a bit, she has a tendency to overheat. Just looking for some comparisons. Thanks.

I'll be running a Hatori with my Aurora. As soon as I get the needles set after break in I'll let ya know where they stand. As far as my YS91SR with the MP5 I couldn't tell ya. I don't count clicks. I just tune it to where it sounds good.

Thanks. When do expect to get your Aurora? My wife says that I already have enough heli's, I respecfully disagree. The Aurora is one sweet looking machine. Let me know how it compares to your MA's when you "Git-R-Done".

Aurora's here an done except for the tail. The thrust bearings that were sent didn't have one race that had a smaller ID then the other. Althought I'm leaving next week for 2 weeks going to Alaska. It won't be till I return and get the AR7100 that I'll fly it. I'm gonna be running an 8v system and don't want to deal with all the regulators and stuff. I used a AR9000 and my 4.8v battery temporaryly to get links made and the head setup.
Here's a rew picture's so far.

it should go onto the rod before the ball links are installed, and it should slip right over it.

I just tried mine and it's like it's already been shrunk down. stuff won't just slide over. I think I'll just use some of the stuff I have for my MA push rods.

Sweet looking heli andrew. Is that a factory canopy, or did you do it yourself? Excuse me for my ignorance, I've only been flying a little over a year now, so I still have a lot to learn. I keep seeing posts about "8 volt" systems. Does this require special servos, esc, or what? I currently run a 7.2 Li-ion with a duralite 5.1 regulator, which seems to work great on my 9351's on my Rap-90. Are ther more significant benefits to the 8v system. Any info on this matter would wecome.
Fly safe, fly hard...or go home.:D
Servo's are driven by electric motors.
electric motors benefit from higher voltage in two ways.
1) faster speed
2) more torque
there is no servo on the market that we use in our helis that is RATED for 8V, although some will state that some servos (JR 8717's) are very capable of running on 8V.
The 8717 at 6V already has ridiculous speed and ridiculous torque.

Thanks Dood. So is there a significant danger of frying your servos, or do you still run the voltage through a regulator? I f no regulator is used, then what size voltage battery is used, 7.2, 8.4 etc. Again pardon my ignorance, I'll get there some day. I just hope I remember wher there is when I get there. :shock:
I f no regulator is used, then what size voltage battery is used, 7.2, 8.4 etc
a 2 cell Lithium pack. (7.4V)
but as you know, a full charged lithium battery is above 8V. Guys just say 8V just because its easier to say.
Danger? lots of guys are using JR 8717's on 8V without issue.

Mine's the same as the other person mentions. I spent a couple of hours today stretching it with 2 screwdrivers through each end and needle nose pliers. The only way it would fit (and yes, I had the links off first) was with some triflow and a ton of stretching..

Thanks again Dood. Now I understand. I just hope I remember what I understood. This age thing is for the birds.;)
