Fastest UL-1 Video

[LuckyDuc]

The UL-1 is a good boat to get into sport hydro racing with. When you start pushing it into the mid-50s you will find yourself chasing your tail trying to make it stick to the water.
If top end speed is what you're after why not buy a rigger kit?

My Ul-1 in trim very close to the 60's is very stable. I have blew over one time going against a gust of wind...

i did 53.1 mph stock boat on 40/52-3 and 5s 20c batts, a 2 and a 3. i cant get the batteries back far enough for it to even get close to blowing over.

Was that 53.1 in race trim or was it a SAW run. Did it have the turn fin on? I tried mine with a straight turn fin and couldn't keep it from blowing over.

Race trim, full fins

I'm going to order some good 3s packs to go with my 2s 30c packs and give 5s a whirl!

[6S HYDRO]

just be smart about it, keep it short and test temps. i added 2 1000uf caps to my esc and it now runs nice and cool.

[Brushless55]

great, and it sounds like adding caps really helps..
I do have a spare 200A esc I could try out?
hmm 6s maybe

[6S HYDRO]

now that would be fun

[Brushless55]

wonder how the stock motor would run with 6s?

[Gary]

The guys i go with to the lake have run 6s in theres and it runs real strong. Havent blowed it up yet!!!!!!

[Brushless55]

I'm going back to the lake tomorrow with my 5s go with a CF40 and see what happens..

today was not a good day for my BEC and reciever..

I'm curious what happened to your BEC & Rx. I've had 2 Tactic Rx's fail; one caught fire & one sizzled/quit; both with a CC BEC set to 5.2 volts. May have gotten slightly damp. What happened to yours ?

What I thought was a 6s BEC was actualy a 2s-3s BEC..
on 4s is was ok but when I put 5s to it, the BEC let the magic smoke out and hurt the rx..

I was able to run my UL-1 for about 2min and the esc temp was 109* and the motor was 120*, so not so bad on temps

Brian used top-of-the-line battery packs and his own tweaked props, other than that it was out-of-the-box stock. The mirrors and plastic headers were removed and an air dam made from Hockey tape under the deck to keep it on the water at those speeds. The NAMBA and IMPBA timers are calibrated often to ensure accuracy, possibly much better than using a GPS and definitely better than a radar gun.
To me Legg Lake doesn't seem to be the place to set records as it appears that there isn't enough room to get a boat up to speed before hitting the first set of timers. Could Team JAG's hydro have hit higher speeds like 160? It's possible had they had the room to get it up to speed first. Look at any videos of their passes and you can see that they're still gaining speed thoughout their runs.
