vacu pickle vs ul-1

[properchopper]

Toni Put a coumpter fan on it and cool the motor with air, I did it with my P Hydro and got a Second at the Nats with that setup.

Actually I'm just playing around with that setup- kinda' just experimenting to see what the Scorp's all about. It did run much cooler exposed on the VS-1. Not spec-approved for now so I'll need to stick with spec motor{s} for any racing apps. Nice fan setup/mount tho' - maybe Wilmer can hook me up with one !

I stand corrected -I knew it was something like that. At those temps the boat would start melting !!

Epoxy melts at 185 degrees.

True in the AC UL-1 but depending on the exact chemical strutcture This is for the Pollyester properties What we all think the hulls are made of.

130°C (255°F) Distortion and Shrinkage.
Crystallization Occurs.
>100°C (212°F) Distortion can occur with non-uniform
heating.
100°C (212°F) Shrinkage up to 0.15% occurs,
stabilizes in 24 hrs.

PET or PET-P (polyethylene terephthalate polyester; Ensitep, Ertalyte) Semi-Crystalline Thermoplastic [1942]
Part of the polyester plastic family
Color: Opaque White Machining: Easy Special Features: Dimensionally Stable; Low Friction
Maximum Temperature: 230°F (490°F Melting Point)

Detox, we run the SV27 package in our club to keep the class Spec to all the racers. Doug and I tested a pickle with UL-1 vs a pickle with SV27 and there was a significant speed advantage with the UL-1 package.

Trini, The Pickle is a smaller/lighter hull than the UL-1 so it should be faster on smooth water using the UL package, but is it faster than my UL-1 in race water conditions? I modified the sponsons (less AOA) of my UL-1 which really seamed to help make hull more stable in race water. See you all soon.

IMO the UL-1 is the better buy.

Pickle v UL1

I have no experience with a UL1.

But I have just completed a Pickle with the IROC set up. See the Vac-U-Boat.com for the details. Phil Pace is excellent with product support.

My four test runs to date were refining the CG. Next is that run with a GPS for speed.

I am very impressed with the speed on 2S2P, and the stability in rough water that is 2" to 3" high.

Will report the GPS when available.

This is turning out to be a great thread!

The UL-1 has lots of room for GPS, larger Lipos, larger motor/esc. Here's picture of my UL-1 with Nue 1515 1y installed.

dang, what speeds did you get?

[detox]

Off topic... no GPS but using the m445 and new sponson mods the UL-1 was easily running over 55 mph. I once GPS'd my stock UL-1 @ 50.2 mph using Grim Racer L40 X 57/3 prop

Lads, top speed is not is what it is all about, unless you are into SAW racing.

Just having fun trying new faster things.

My Ul-1 with an 8xl was a total flop. The hull in stock form will not handle the speed or acceleration. Chine walk was ridiculous. The extra weight from the xl can was too much to keep it cormering flat and it wanted to hop through the turns no matter what i did. IMO the stock setup works best with the UL-1. The aoa however, I think is way too aggressive for any kind of chop. I haven't built or driven a vacu-pickle, but I've seen many vids. It looks to handle quite well. I'm sure it will hold up better durability-wise than the UL-1 by far!
