Default RV tailwheel steering link

The three RV-8 SB kits are still somewhere between Oregon and Virginia. Looking ahead for some suggestions.

These are the two tailwheel steering links I've found:

What is the general consensus? Is there something else I should look at?

I'm at the same point with my 7. Installing landing gear now and have a Bell Tailwheel. I like both options and both will give you good support of their product. Even though JD Air is in my area (PHX AZ) I am favoring the Rocket control arm due to the fact that it has a provision for a TW tiedown.

Default Rocket Steering Link

FWIW:

I have had the Rocket Steering Link installed since 10/2004 with 1550 hours of service and have had no problems with it. The control arm was replaced once during this time due to normal wear. At annual inspection the heat sleeve cover is replaced and the unit is lubricated per manufacturer instructions.

Default Tie down

Not sure I would use the steering arm as a tie down point but that is your choice. Then again, I'm a little biased

The JD air steering links are very streamlined and have a balanced spring system installed. Ready for shipping today!!

I have the JD Air fork and love it! Much better ground clearance than the stock fork.

Default Lynx tailwheel springs

I had the Lynx tailwheel springs on my RV4. When I purchased the RV8, it had the stock springs. I purchased and installed the Rocket link. After a month or so, I removed the Rocket link and installed another set of Lynx springs.

I think what I didn't like about the hard link was that any time the tail wheel touched with any rudder deflection, I also had tail wheel deflection. That would result in a sometimes abrupt change in direction.

I install the Lynx springs with a bit of slack, so the first bit of rudder deflection does not move the tail wheel. Thus no abrupt tail movement at touchdown.

Just my impressions, having used both systems.

Thanks for all the replies.

I'm thinking I go with the stock setup at first, then shift over if I still want.

This practice has been adopted by a few local guys. Sadly, it didn't save one 8 who ground looped his shortly after installing a link type single arm tailwheel later.
They give very positive control and people love the "feel". Many swear by them and have positive experiences. I suspect there are thousands of hours on them now and only a few instances of betrayal, which may or may not be the product.
However, each time I see an 8 ground loop, there is one common thread. I know Randy and he is one of the best sticks I know.
One of these fine people offered to send me their latest design to test for myself and comment after reading prior posts of mine cautioning folks about thier use. Sadly, they did not come through on that so I have yet to fly this design.
I believe the bigger issue with 8's and ground loops is gear alignment. If you start squirrelly, a more sensitive tailwheel set up is going to make it that much worse when things start to go "bad".
Just my two cents. I still want to try one on my 6, but I don't believe that is a fair comparison to the 8's geometry. The only model that seems to have this issue is the 8 from what I have seen reported here and from other highly experienced sources close to me.
Not bashing, just trying to help unravel what I think is a bit of a mystery.

Here's a few data points from a Rocket link vendor's 10 years of experience with the product:
  1. The Rocket link was originally produced in Canada by Terry Jantzi. Wayne Hadath has been making them for the past 8 or 9 years.
  2. There are probably around 1000 out there in service. They are quite popular, rarely returned, and relatively trouble-free.
  3. The steering action of the links, regardless of who makes them as there are copies out there, is crisp. Some prefer that feel. Some don't.
  4. The action is slightly asymmetrical as pointed out by other posts. This shouldn't cause issues under normal ops with proper maintenance.
  5. The RV-8 is arguably the least friendly RV on the ground. Please don't shoot the messenger. It is what it is. Consider this when making your tailwheel steering decisions.

Related thoughts: The locking pin/control arm of any full swiveling, steerable tailwheel requires periodic maintenance regardless of the manufacturer. You're dragging it through all sorts of dirt and mud and it WILL wear out. The maintenance of your tailwheel is important. Don't neglect it.

There are many fine tailwheel products out there. As with any other option on your aircraft, it is up to you to find the right one for you.

BTW. your choice in tailwheel products won't keep you from making a bad landing, but not properly maintaining your tailwheel certainly can add to the excitement. Don't find out that you neglected the locking pin/control arm maintenance while you're on the runway. Check it a couple times a year, during each oil change is an easy way to make sure it's up to snuff. You gotta wait for the oil to drain anyway!

YMMV...
