The new from the box.. This doesn't look like nearly enough gap.

I like about twice that much myself (4-5mm). That was about 2mm right there out of the box though.

Easy enough to correct. I know I usually go through a new boat setting it up before taking it out on its first run.

My bet is the stuffing box is going to break the shaft on the braze that angle is a bit to much

It will be interesting to see how it does as you start tuning on it. Looks like the prop needs to be aimed down slightly to keep it from blowing over.

Temp checks and trying to keep it on the water.

Hello all, This is my first post here and having just pre-ordered the Blackjack 42 it would seem to be the best place to ask a few questions.
Never having a boat before the speeds this one can deliver might be a bit much for a newb such as myself. My idea would be to run the boat on 6s for awhile till i get more familiar with the boat and its handling, tuning, etc. Some concerns are what effects this will have on the power system itself running 6s instead of 8s, will it run hot or cooler and will i need a prop change to accomplish this? Secondly, could someone tell me what the ID is on the cooling lines as the first modification i wish to make is cooling the motor and ESC independently and utilizing both water pick ups in the rudder.
TIA, Chris

I wouldn't worry to much. Most RTR's have dual rates built into the transmitter, I think its called so you can slow things down. Someone will correct me if I'm wrong.

Thanks, allthough I prefer actual user input I'll reach out to horizon as well.

The BJ 42 DX3 controller has a throttle limit switch on top of it with 3 settings that can be changed. It's got a 50%, 75%, and a 100% setting. On the 75% setting the boat runs stable as can be in the low to mid 40's mph range and on 100% it turns into a powerful Beast. Below is a photo of the transmitter and you can see the switch.

Also I guess I can go ahead and post my latest video over here as well.

Perfect, just what I needed to know. Any chance you could tell me the tubing ID for the cooling system? Id like to separate the esc and motor on their own cooling loops or do you think that is overkill.
Nice video too!

The cooling tube is 6mm outside and 1/8 inside. More cooling can't hurt but the stock system doesn't overheat at all, not even close to overheating. I would use this tube here https://www.offshoreelectrics.com/pr...ng-1%2F4-clear

Excellent, thanks for the info. FYI, I reached out to Horizon about running on 6s and they do not endorse it, kind of expected that. Not that it matters at this point as your suggestion on throttle limiting seems like it will suit me just fine.
