Is there a trick to make the process of screwing the plastic ends on the rods easier? I find I need to force a lot and there's quite a few of them to do.

Grab the rod with pliers, insert a hex key in the plastic hole, twist.
First, do it by hand then...

^^^^^^^^ The trick is not to listen to this guy, I can only image the condition his links are in!

To answer your question... you need the PROPER TOOLS. Get a set of ball link pliars. They have slots in them for gripping the rods but the most important part is the rod link end driver. Get one with a fat handle, its easier to twist. These tools dont mar up and stretch the hell out of the link ends.

There are several after market ball link tools that the plastic link inserts into and gives you a lot more comfortable ability to screw the link onto the rod.

I just got one of the link maker tools from HeliProz and it is completely automatic and just requires you to start the links onto the rod, and then it does the rest, including making all the links the same length.

+1! I have been doing it the same way for 22 years. Granted, it may be the hard way to go about it and it scratches up the pushrods but I can't justify buying a link making machine for the small number of links that I make.

Some you can twist on with your hands. When you get into aftermarket ends like Rocket City, there is no way you are assembling more than 1 link with your fingers unless you have gorilla paws! If you have a set of pliars that will grip them and not gall the hell out of the rod, go for it. You should have all the right tools anways, it makes life easier.

I would agree with you, but I won the gift certificate for it at a funfly.

LinkMaker!!
A tool that you wonder how you ever did without it for all those years..
Before I got it, I used a link tool on the plastic link and chocked the rod in my drill.. after awhile, you could get them pretty close, and for the other end chock the endvwith the link you just installed into your drill and run the other link on...
Good Luck...Stan

Do any of these fancy tools ensure that each link end is threaded on the same as the other side? Every heli I have worked on that I did not build, the links were not symmetrical. Its amazing that there are not more crashes due to a link end falling off because it was only held on by 3 threads. Maybe there are and people are just to embarrassed to talk about it? lol

A few years ago, I got me one of these. Much cheaper than the links provided and it is easy on the fingers.

A Tool Like That...
Rafael23cc

That is the type of tool that I used to hold the plastic link while turning the rod slowly with my drill..you are 100% correct about that being a LOT easier on the fingers...
Thanks for sharing the link...

The Link Maker Tool is a pretty amazing unit though.. you have to build quite a few helis to really warrant one though, and I do a minimum of 6 or more a year, so it comes in handy.. it is great because it will make all the links the same length and both ends will be screwed on equally.. nice piece!!!

Thanks Rafael!
That just went on my Wish List.
I have the HeliMax ball link pliers
http://www3.towerhobbies.com/cgi-bi...?&I=LXLSV3&P=ML
and wish I'd gotten them a year ago. Best money I've spent on tools.
Saves your fingers and rods a beatin' and makes link installation and removal a snap.

Key: Need a PAIR of ball link tools
Almost all the ball links we need for a heli consist of a rod, and two ball links, one on each end. The key is to hold the rod, and get one side on and get a few turns started, then put the other side on, and turn it a few turns.

Then, you need a PAIR of ball link holding tools, such as the Mavrikk tool

This is a single purpose tool for larger helis (450 to 600):
http://www.amainhobbies.com/product...-Ball-Link-Tool

This is a multipurpose one which covers heli's from 250 up to 90 Class
http://www.amainhobbies.com/product...ink-Sizing-Tool

There are other manufacturers of similar tools, but these were the first that came up in my search. These also have a longer handle than most, so you hold it like a screwdriver, in your palm, and not just with your fingers. The one on the top (single purpose) is a lot cheaper than the multi-purpose one (which if you buy a pair, you might as well put in the rest and get a LinkMaker). There are less expensive ones available, and there was a site that was selling them in pairs for about the same price. Don't remember where.

Once you have the ends on, you put one of these tools over each of the ball links on the end, and twist them on. There is now no need to hold onto the rod! Don't worry about which hand you need to twist. Surprisingly, the amount each ball link threads onto the rod ends up about even. If one side ends up threading on less, you can use your ball link pliers (or regular pliers) to hold the rod, and thread that end on more.

I would not recommend the ones with the "wings" on them. It looks like it would be easier to turn, but you end up using your fingers (like a wingnut), and not your palm (like a screwdriver) and lose any advantage that the tool should give you.

These tools cause much less stress on the fingers, and cheaper than the LinkMaker 9000. I don't make enough ball links to make the LinkMaker worthwhile, but I would not throw it out if someone gave it to me for free ....

Just had my morning coffee ... Internet search is working better now!

PS: Found these under "RC Cars" section, but they work the same.
