This is not me but I had saved the video on my computer. Listen at the end it was a 59mph pass.

That was Brian Buaas testing the UL before the public release last years SAW at Legg Lake... from what I understand he got 63-64mph after tempering with props and air dam... the rest was stock.
:::::::::::::::. It's NEVER fast enough! .:::::::::::::::
Nate is an idiot.....................couldn't help it. Just kidding
Mine also did 50.2 mph using 25c G3 lipos and GR L40 x 57/3 prop
..................
Best i got is a 48.1 with a M440. I have bigger props to try just working on getting good run times and not so much heat. Maybe tomorrow if i get out i will bring a video camera and put some bigger props for some speed runs.
Nate, you believe GPS but don't believe the timing lights? Seems arse about face to me.
Nate, what speed did you get on your moded UL-1?
DJI Drone Advanced Pilot

Thats what he meant. Brian pulled that one from a box and swapped props. Also you claim your to do over 55? that is screammmminng. I cant wait to see that video. You may end up with a plank out infront holding your lipo's to keep the thing on the water!HA!
What are you guys doing to be able to produce upper 45+ mph passes? I've got a scratch built twin-wing Circus Circus boat (painted as the American Spirit) with a UL-1 motor/esc and have only pulled off 44.2 mph passes with an X645 prop (25C MaxAmps batteries). Tried the M440 next and only got 42 mph. What prop was Brian using when he hit 63-64 mph? Thanks for the help!
Glass smooth water with slight wind ripple on surface is the trick for fast speeds. If water is too choppy prop and hull will jump out of water slowing UL-1 down. Deep strut setting helps also (1 1/8" -1 1/4" worked for me)
Yea lol. I really wanted to wait until my GPS arrived so I could find out... What if it was 60's lol wow!
Nah Im exspecting 52-55mph...Im almost sure...could be wrong, but Im hoping, cause she's screaming.
Iv done all my passes so far on an m445.. Id like to swap over to an x442 with 6s2p.
Then Id most likely:
A: Need Air brakes
B: Blow over before 65mph
C:It blows up in flames.
Haha.
I need and x445.. S&B Got one anybody???

That was my video of the 59 mph pass, and I witnessed the other passes in the 65 mph zone. I drove that boat that day, held it in my hand, and it was only changed as Brian said. Know too that SAW times are an average course speed, usually the boat accelerates way faster than the average speed at the end of the course. I watched Jeorg M. do his 141 mph record in 2006, and trained observers estimated a 160 + speed coming out of the trap one one single pass. I KNOW I'll get flamed for this [ Douggie help me out here ] but all this " what's the fastest it'll go" hysteria seems wasted on a RTR which handles reasonably well at a design speed in the mid forties but develops all sorts of spastic behavior at higher speeds.
Whatever !

I really don't recall, but I think Brian disclosed this somewhere in a post. It's really a moot issue; once Brian "tunes" a prop, It doesn't resemble anything us mere mortals can get our hands on, just so you know. As a matter of fact, I showed up at the NAMBA time trials yesterday ready to set the P-OPC tunnel record with my rather fast running VS-1/UL-1 tunnel, and there was Mr. Buass grinning at with me with his well prepared fleet. With essentially the same setup [other than prop], Brian was a good 6 mph faster than my VS-1, which unexpectedly developed all kinds of outdrive issues culminating in a terminal servo malfunction.

Nate, While I honestly can't fathom where you're going with this, please consider the following :
Brian's 59 & 65 mph passes were made through the SAW traps.
A 60 mph SAW pass takes approximately 3.75 seconds.
If the noob[sic] wants to make 3.75 second runs there are bolt-on Grim or Octura props that can make it happen.
There will, however, be some downsides to this

Well I have another short video, This is were Im at so far.
When I got to the lake and had everything ready...I started running the boat out to the middle of the lake and all the suddon I hear a thud..lol
I must have hit a damn turtle!!
Well it bent my Speedmaster just a bit, then chopped off the tips of my prop,
I was a bit mad but still got 2 passes in, I belive it has way more in her but the prop was a bummer...
I need an x445 then I think it will see 55mph...
Ill know tUESEDAY for shure when I pick up the GPS from the post office...
Here it is.. First pass I was on and off half throttle playin around, second pass was beautiful!!!
