REFLECTOR: aileron binding

Brett, I have the part number at the hangar and I will get those tonight. The factory cable is a custom cable made for Velocity and I think I measured 4' 6" and the closest off the shelf cable was 5' or vice versa (It's been a while and the gray matter isn't what it used to be). I had to drill new routing holes  the forward gear bulkhead but I used the existing holes in the firewall.

Best regards,

Nick,

Do you have a part number?  Is it a direct 1-for-1 replacement?  If so, I'd like to capture it on the Wiki.

Brett

Reiff,

I too thought there was too much friction and slop on the ailerons. I talked to Teleflex controls about the problem. They told me about their TFXtreame cable design that eliminates most of the slop and decrease the friction.  I installed the TFXextreme cables and the friction was reduced significantly and very little sl! op. I haven't flown the cables yet but I can tell the difference between the TFX cable from the original cables.

Don,

Here's a collection of comments, impressions, and stories about ailerons that I've collected over the past 3 years. Some of these are even true. I don't pretend to be an expert, but I'll put this out for anyone that wants it:


1.       Velocity ailerons frequently feel stiff. Once the engine is running, the vibration eliminates that issue. (I'm not claiming that this is an acceptable solution, just that I've heard it from many builders.)

2.       Some have improved the situation with bearings, universal joints, and push-pull cable lubrication.

3.       The Rocket Racing League wanted to eliminate the stiffness (since they flew half of the time with the engine off) so they replaced the push-pull cables with a series of pushrods and bellcranks.

4.       When I was in Sebastian this winter, Velocity was building the twin. They were considering using "a higher grade" of push-pull cable to reduce friction and slop.

Hope this helps.

It's not the aileron. It's something in the cable. With no cable attached the aileron moves with ZERO friction. But once the cable is attached, it's sticky.

I'm hoping that I'm creating a problem where none exists. When I had both wings on, Malcolm said the stick was easier to move than most others. So perhaps the weight of the other aileron cancels out some of the cable friction.

Don,

With the Aileron torque tube travelling through an arc - a spherical bearing will help with binding.  In my case, I'm going 'old school' (aka Long EZ/Cozy) - and using a universal joint at the connection between the torque tube and the aileron, in conjunction with the spherical bearing at the wing root.  Parts are available off the shelf from Cozy Girls, and Infinity Aerospace.  Let me know if you'd like part #'s, etc.

John
