View Full Version : dominator front spring
03-05-2007, 01:55 PM
If one of the front springs on a dominator nose gear goes flat, How do you re-bend and temper it? I know you can buy a new one from RFD, but even the new ones have gone flat for people. I have access to heat treating facilities etc. Just wanted to know if it can be repaired or re-arced.

Scott, take a rosebud tip and heat it slowly and evenly to a cherry red condition, the let it cool without any help, ( wind, water, or oil), even keep
it out of the breeze if possible. After cooling completely take a hammer and
a piece of pipe and reshape it to match the other spring, then have it heatreated to Rockwell C26 to C32. Carey

have you completely, absolutely totally run out of something to think about?

If you find a fix that works...I'll send you mine to fix it too!
Went flat the first flight and still is!

Well we have a heat treat shop here at work, so getting to a rockwell hardness is no big deal as long as I know what to get it to.
And Yes Barry, I will take care of ya.
Reason is David: I bought a used ultrawhite with a 582, and I might end up liking it.
And by the way, welcome back David. :)

I've never heard of this before, but If I were Ernie, I would want to know about this. Have you guys talked to him about it?

Rick, sent PM.

Is an Ultrawhite an Ultrawhite if it has a 582? I don't know all the Dominator models.

Mark, the ultrawhite is the stripped down version with no pod. Usualy it has a 503. So what i have is a stripped down light weight gyro with extra HP.
With the electric start 582 it weighs about 330lbs.

Scott, how about some closeup pics of this system/situation ?
Couldn't you use a coil spring for this application ?
BTW.... I think you might be getting addicted to this sport !
Who is getting the Screwdriver 2 ?

Scott, a Ultrawhite is a basic version with a 503 Rotax - I wouldn't call it stripped down as the more " loaded " versions really only have a nose pod and bigger engine over what the basic version has.
What you have is a Superwhite.... That is a Ultrawhite with a 582 on it.
Then there is my gyro, what is known as the Dominator performance model - which has no more performance than the Superwhite other than a slightly higher top speed.
Then there is the two place models.

Thanks for straightening that out Uncle Ron! :first:

Well, fly the thing already!!!
03-07-2007, 06:33 AM
I taxied it yesterday, to try to get used to the steering. I just redid the fuel system, and it still needs help on the wiring, I had to replace the engine ground wire yesterday, it wouldn't start. So that leads me to believe that it all needs to be redone, but it should be OK to fly. Needs more instruments too, no altimeter or water temp or CHT. But I have a few spare gauges! I hope to fly it this weekend.

Did that Dominator come with a paintball gun mount on it?
03-07-2007, 06:58 AM
I wouldn't put a CHT on a 582. when it is to hot on the CHT your H2O and or the EGT should be off the map.
03-07-2007, 07:25 AM
No, no paint ball gun mount.
I agree on the CHT, good for tuning and jetting to monitor what is going on. but after that the H2O temp would be more important.

Scott, I think that some are curious where you got this machine.
Is this secret information or is it to be public knowledge ?
I'm guessing that if it had a gun mount , that it might have been owned by no other than Tim Verroi, who I am guessing is the "Tim" that is the new owner of the Screwdriver 2.
Can you at least verify or deny these claims ?
03-07-2007, 08:21 AM
Chris, Yes you are correct, Not trying to keep secret, I just figured John or Tim could post about thier machine if they felt like it. I happened pretty quick, I wasn't in the market for a new gyro, So Here I am with 2. Screw set the whole deal up, The gyro is in good shape, just the fuel lines were hardened, and some of the electrical is corroded, or could be replaced. I'll have to pretty it up some.
