50" Hydro Build

[Make-a-Wake]

Thanks Keith!

I am using this coupler - http://www.offshoreelectrics.com/pro...oct-ocfhe8mm25

The flex must be standard 1/4" cuz the coupler fits tightly. Got to get the ESC fired up for the first time in the morning...........im off tomorrow so should be able to run her in the afternoon!

I always get a little creeeped out when firing up a new ESC...........gotta make sure the throttle range is set correctly upon initial start up etc..............

Not looking forward to pluggin in 9s without a spark eliminator.............Keith, have you plugged some high voltage packs in before without the eliminator?

[madgadget]

plugged in my 12s stratus and 10s Razor helis every other weekend for almost a year before getting a spark eliminator using CC HV85 and HV110 esc's. fwiw
Are you ready for me to video the maiden?????

[keithbradley]

Yeah, I didnt have anything on this one:


I ran up to 10s2p in it. I use 8mm bullets and just keep my fingers off of the non insulated part of the bullet and quickly put them together. If you commit to it and just quickly put them together (dont be gingerly about it, that make more of an arc) it doesnt really damage the bullets... Maybe over a long period of time, like you might have to replace them after 100 plug ins, but nothing too terrible. It is loud though. Alot louder than 6s2p, seems more than twice as loud.
I ran a 240HV ESC in that boat and never had any problems with it either. I know some people say the spark can damage the esc, but I've never had a problem.

So, no biggie just pluggin it in with the huge pop i anticipate...........hmmmm. Doesnt hurt the caps???

Not really looking forward to the POP.............can i add a spark eliminator??

Mad, Im just south of you a bit..............but may be a long drive................

Thanks guys

Wishful thinking more than anything else on the video.

[Make-a-Wake]

Well..........kind of a nightmare drilling the holes in the stringer for the ESC mount..........but got it done.

Also added the rear hatch cover, made it from thick plexiglass. Had to do it the way i did with screws only at the top cuz i have to spread the bottom of the canopy apart to get the lockscrews in. Then i'll just give it a really good tape job all the way around and at the bottom.

Still tryin' to get her in the water today.................

Are you going to run on 10s?
Looks good by the way!

[Make-a-Wake]

9s...........................I'll give the motor a slight break.............plus im turning a good size prop. Thanks!!!

9s...........................I'll give the motor a slight break.............plus im turning a good size prop. Thanks!!!

wheres that video bro!

[H2OCamel]

I wanna see it too!

[Make-a-Wake]

Ran her today....................


Must read the following before viewing:

Not real pleased with the whole vid run..........couldnt open her up at all........i know the first look is what folks remember so keep in mind this was a "trial" run and i set things up like i thought they should be............wild guesses in a few areas for a boat this big. She's faster than she looks in the vid cuz of the sheer size.

1. Went to the neighborhood lake cuz there is a resue boat there..........full size boat..........needed that "comfort" for the first time. The lake is a bit small for the big ones.....had to make some slow turns.

2. Never brought it in for a temp check........or any check for that matter after 1 minute and I know better........got all excited and caught up in it, and feel pretty much like an idiot..........we've all pretty much been there

3. Never got it past about 2/3 throttle cuz of the lifting........

4. ESC thermaled due to not much water flow for some reason.........dont know if i picked something up running so close to the weeds......or if there is too much resistance in the long series of lines.....too small of rudder pickup........not sure, have to figure that one out........there wasnt much water in the tubes when it came in.

5. ESC was still working after cool down 30 minutes later........no burned smell, no popped caps.............melted the shrink right off of it though.

6. Motor was 137* without much cooling i guess............

7. ESC caps were over 200*

8. Gonna have to lower the strut i imagine to get the rear up................this was all just done under "what i thought" would be good type of guidlines.

9. The 2028 is a HOG.

Cooling is obviously an issue..............but the big 2028 handled a 3+ minute run with not much cooling i imagine

Gotta get the rear up i guess.................Any input is appreciated

Never fear........WOT runs and 60+ will follow soon!!!!!! I go down swingin'!

Where is your CG at relative to the sponson transoms?

[keithbradley]

It looks like it has potential for speed in the short bursts where you start to roll into it...I was expecting a lot slower after reading your disclaimer!
It did look extremely wet though, especially with the grandma driving in the turns. I could see why it would run hot if it didnt have optimum water flow. It should run a lot cooler just getting it on a bigger lake where you can drive it harder, aside from teh cooling problem.

Glad your SF240 didnt puke. If the caps were that hot, I wonder if it would be a good idea to just replace them...caps are pretty cheap.

[Make-a-Wake]

Thanks guys............Rum, the cg is 4.5 inches behind the trailing bottom edges of the sponsons.........remember, 50 incher here, so let's keep that in our formula!

Keith, yep, grandma in the turns, but I'm sure you saw the room or lack of, that I had. I have the larger long lake to open her up in, but I gotta get the attitude figured out first.

Thanks

[Brushless55]

it looks like it has more to give
