I've never had a track big enough to accommodate T-jet power more substantial than a mean green on pump gas but I dig this thread. I think the off the beaten path engineering stuff is always interesting I used to really like in the 80s when I would read Hot Rod and they'd have pieces looking back to the 50s and 60s when people had to build their own speed stuff because the industry didn't exist yet.

Buiding An Aurora Thunder jet Armature

Tjetsig are you going to have your monster Armatures at the upcoming race at skipac?

Did tjetsgrig bring his new Big Block Super armature to the skypack race? If so how fast did it go? Inquiring minds want to know!

Hey dt! Still have some R&D on this thing. Although it has gobs of torque off the line, the width of the ends of the poles prevent any descent top end, too much in the magnets for too long! Ive got one I trimmed down, just need to wind it up. Will keep you all posted!

Well, this thing spun up so high, it shot the windings out to the end of the poles! Im gonna super glue the windings on the re-do!

That was unloaded, didnt even have drive gear on it! Things translate differently to a loaded motor with all gears, wheels, body and traction magnets, thats why I got excited until it went down the track. The numbers were slightly off, we'll see how it goes after the trim job. You never know ANYTHING until you get it on the track! Just because it sounds good while adjusting brush tension, doesn't mean it will translate to good numbers!

What happened to the Arm With the 36-d Lamination's? That was the one that revved up so high that it tossed the wires your were going to rewind & epox the windings. Then you found some other lamination that were even biger that you made an armature
out of.

What I am talking about is the following; you built on Armature using the 36-D laminations that are the first one the one I believe that threw the windings off the first armature. You had said that you were going to rewind and glue or epoxy the windings. Then you found some other Laminations that were even larger than the 36-D Laminations, that is the one been working on lately the second Armature. So my question is did you ever rewind the first Armature, and if so how did it work out?

Have you cut down the lamination on the two special armatures yet? I did not think that you would need to cut down the laminations on 36 D armature as that armature has been done before and worked ok. I under stand about the second armature as the lamination are even biger. Inquiring minds want to know.

I cannot answer for sgrig, so your question remains.
however, being friends with him for 30 or so years, I can tell you when he has news, he will be anxious to share it.
likely other builds, winds, priorities are coming before that set of experiments.
not to make light of your request and I think you should continue to ask.
just wanted to share what I do know.
