GPS SPEED REPORT

Here you go guys;

Stock running gear (outdrive)
Stock prop

Blueprinted/sanded bottom
removed battery trays

4900mah lipos

Severe chop, the river was terrible, the rowing team was out kicking up wake and made it almost impossible to run wide open for very long.

37.2mph


Not too bad for stock prop and electronics, huh?

I could take a pic of the GPS screen with the highest top speed recorded? LOL

Honestly, It was one of those "its drizzling and I need to get my boat fix" sort of runs.
This weekend, I will video the run and show the GPS.

37.2 stock is most impressive!! Im planning on bringing mine to sundays club fun run. With a little luck, might get to tangle with a few SuperFlips on the 1/8 mile course! :w00t:

Depending on how lumpy the water was and how the boat was trimmed, 1/2" waves can cut 1-3 mph off a top speed with that kind of boat. Small cats are fastest on very smooth water to water with just a slight ripple.

well I gps mine with 14 cell, intellect 3600 stock motor,esc and a 645...I got 43.3mph..Then my cousin crashed his SV his top was 47.7..with nimhs and an ammo 2600kv...Being that my esc was shutting down, we swapped esc's and with 2- 7.4 cell lipo's i got 51mph(less weight and more punch freed her up an the ammo 2600), then my futaba glitch and at 45 plus she slammed into a concrete drainage in the retaining lake every thing came through the hull( gps, batteries) but it was refreshing, i felt good...ordered a new bj26 bl hull....

So Webdr why are you selling the Bj?

I just dont feel it will ever have the "turn-a-bility" that I thought it would. The aeromarine hardware is not shipping and I dont feel like piecing anything together just for the sake of hoping it will correct its inherently bad turning.

I gave it the benefit of the doubt but so far, I have not been impressed.

With trinity 6 cell 4200s and a x642 with the stock motor, my bj ran 36.0
