UL-1 motors old and new, very different

[ray schrauwen]

Was at the pond today play for maybe the last time. A friend was there, El Presidente of GRMM Club in Canada. He had a Bling Rocket setup for LSO with an OLD UL-1 in there.
When I looked at the rear end I was impressed! So much copper that you can NOT see the laminated stack at all. The rotor has a different construction also.

I took a pic or two and went home, compared it to a UL-1 motor I bought 8 months or more ago and to say the least it was jaw dropping.

I'm guessing here but, possible they changed from D to Y? or just cut the amount of copper in half? Who knows but pictures say a million words so I'll let you look and see for yourself.

These motors are a world of difference. The pic of the new motor with the 2030kv stamp may need to be downloaded and zoomed to see what I mean.

The old motor looks like it was wound by Steve Neu, the new one??? Nevermind...

Please Aquacraft can you bring the UL-1 motor back to what it was!

Ray, hows the weight between them?

Problem is, I don't own the one in the first pic. I'll see if I can get him to remove it from his boat sometime. I took the other picture with my crap camera but, I am shocked at what I saw at the pond two Sundays ago.I wish I kept my one old UL-1 motor can from waaay back.

I think they may, MAY, have traded off some of the copper for steel but, that's a guess.

Why does the first one look like it wet through a blender/chopper/cement mixer?

[photohoward1]

Oh and I still say spec'ing those motors was a huge mistake. There are way better variants for the same price now.

For 100 millionth time.....available in a RTR is part of the picture.

I suppose because he used clear silicone to seal the waterjacket... Looks like the dogs breakfast. He has had that boat and motor for quite a few years. His nitro Jae Rigger on the other hand is spotless! Go figure he started as nitro so electrics are more secondary toys to him I'm assuming.

I love getting your neck hair to stand on end. Wait....Do you have neck hair?

[ray schrauwen]

I know he has a neck at least.

Doesn't effect me as I don't race anymore but I hate to say I say this coming. I honestly think the quality of Aquacraft products has gone down. I think it would be impossible to do a thinner layup on the newer hulls, still haven't figured out the flex shaft issues, now as I've been reading more people are burning up the UL-1 motors.
Thanks for the pics Ray, was just about to buy a new one for my whip, think since I'm not really constrained by rules I'll give one of the small Leopards a try.
We just choose motors that have about the same KV and size to keep it competitive between like style boats. We just like running an oval and passing each other, no winners no losers. I don't want to beat up on the UL-1s too badly with my Whip.

I thought I might have the older version but I just checked: no such luck, mine was bought brand new two years ago for my Minicat USA's Samurai Cat, looks just like the one I bought last month for my BBY Zephyr. They both look like the one with the "2030kv" stamp.
I just want to understand how can they cut the amount of copper? Unless it is a different wind? I have couple of others but they are stored at my Mom's home, will check too.
Of course I don't push my motors like you guys do, but it is a pity that they changed the way how it is made. How long ago since you guys noticed the change? Just curious...
