I'm interested in a tail spring. If possible I prefer a tailspring that is a little longer, then cut to the length you want. I don't like how the tail "spring" was done on the project I took over.

Did I mention that was Phil Lankford with a "k"? Alright, the whole point of selecting an appropriate material is to get the desired properties. I am aware that 4130 is a hardenable material.

Ten days and counting... Who: All those interested in Q's and Dragonflys, especially those powered by alternative engines. What: Experimental Aviation Fly-in When: April 27-29,

Jim, Can you point me to the QAC UNI stiffener mod. If not, do you remember the details. Joseph Jim Patillo <logistics_engineering@...> wrote: Rene, Here is another

Great! That would be good info. It appears there is a market for 3 springs currently. Joseph Peter Harris <peterjfharris@...> wrote: Joseph the tail spring that Sam and I

850 hours. Interesting. Do you have any pictures of the receiver? Joseph Rene Robertson <q2robertson@...> wrote: Hi Joseph, For what it's worth I also have a 5/8" 4130 steel

Diverging slightly, has anyone considered lengthening the tailspring (by perhaps 1ft) in order to further improve ground stability? Allan Farr

Rene, Here is another example of people not listening or choosing not to listen because of their bias's. Between us both, we have a "proven" total of 1650 hours in test with out any problems. That

Joseph the tail spring that Sam and I are using was properly designed for the application by John Tenhave. I should be able to get a price /outlook this week. Peter _____ From:

Phil, Stronger is not always a good thing. If you make it too much stonger, something else will break before the previously preprogrammed weakest link and in the Q2XX case that is....? either it

It would be nice to get more dampening in the tailspring, since too much spring can cause the plane to bounce back and forth front to back on the runway (during which time you're along for the ride).

Be somewhat careful about assuming Jim's 5/8" is good for you. I believe Jim has complied with a plans change to stiffen the fuselage, his plane might not weigh the same as yours, and he might be a

Hi Joseph, For what it's worth I also have a 5/8" 4130 steel tail spring that has stood up very well for the last 850 hours. Instead of Jim however, I used a solid steel 5/8" 4130 rod mainly

Hi Bob, I agree that I would not want it to be too stiff so as to result in damage to the fuselage. However, Jim says he has 800 hrs. on his 5/8th 4130 spring. This would appear to be

Providing, the rudder controls are placed where you can get effective braking with full rudder deflection. My new Q is a stretch too long. This morning I got a leg cramp, but little right brake. Real

Another (untested on a Q) option is one that Jim Ham applied to his Q200 taildragger. He used a flat steel spring, similar to a Cub, bolted to a receiver mounted in the end of the tail cone. It

Sorry Paul, I had sent it out in an earlier note. It will be 18,19, 20 May 2007. Will you be joining us? Kevin
