Looks nice. I'd try to run her a little looser. Looked like it handled a little too good.....

That thing is fast as hell and handles like its on rails . What a show. Sounds like its got more left in it.

Thanks guys. Yea, I usually run her on rougher water so my cg is a little forward. She was a little wet on this run.

No gps on that run, although I have gps'd it at 70mph. Hopefully I get my other prop in the mail today!

How was your temps after that run ,you ran a long time , how many m.a.h. did it take to recharge them ? Running .150 cable ? Were you thrusting with your motors or struts( looks like motors), I like how there is play in the shafts on those motors to allow a thrust bearing at the motor to take 100% of the thrust load from the cables. I'm really wanting to run 5s on the 4 proper now :bowdown:

That was an entire run. 5s1p 30c 5000mah per motor. Ran till the lvc cutoff set at 3.4volts on that run I believe. Generally I don't do that, but I figured since It was being filmed, I'd get a good Idea of how long I could run reliably. I ran .187 cables, but I'm sure you could get away with .150's. Thrusted from the motor with thrust bearings, 3/16" gap between the struts and drive dogs. Super fun boat for sure!

Everything stayed good on the temps ? I have been running .150 and thrusting with the struts, ran it with the thrust on the motors and was a little unstable and wanted to push turns on full throttle. I am going to try thrust differential setup next time to see if it helps the boat hook better. Waiting on the boat to be done at the paint shop.:beerchug:

Rum - That thing is unbelieveable!! Nice job. What lake is that? I assume it isn't always that calm? I can get calm water in the mornings sometimes, or after it rains, but that's about it.

Shooter, It's a small inland lake called Diamond lake. I keep my pontoon boat there at my sister's house. It gets a little weedy by shore mid summer, so I usually take the pontoon out and anchor. It has good tree coverage, so there is always a calm area. Good news is this gals gonna make a comeback with a pair of 1520's and modded 447's. It will be insane!
