54" Bonzi Fountain build

Chris the boat run nice , sorry about running it up in the woods ! can you raise the drives anymore this will lessen the load ? Also you need to send me the other 6017/3 and the 5517/3 that you want bored out email me for my address , How do you feel the 6017/3 modded by me are working ?? thanks chris

Yeah I'm going to send you the props tomorrow. I was going to do it last week but I took the wife and kid to a last minute Disney World trip.

I can raise the drives but as they are the boat rides super nice. If I raise them up I'm afraid it will get lose and sloppy.

I didn't notice much change in top speed with the modded props other than a slightly quicker hook up (hole shot) In fact based on the GPS it was 3 MPH slower but I'm not entirely sure the GPS had a signal the whole time. When I took it out of the boat it said "no signal" but had a top recorded speed of 52 MPH.

I'll see what it does with the 5517's.

Hey Chris........nice lookin' run.............very stable! Have you tried all the possibilities yet? Swapping the esc's, setting LVC to "no protection" for a quick run etc.......etc............ Have you checked cap temps? Have you tried 2p? I had a boat that cutoff very quickly on 1p............2p went great!

Doesn't seem like 150 should cause it to thermal

[Make-a-Wake]

I bet 2p solves it.

Hmmm...let me try a few things this week. If I can avoid another 500 beans on new ESCs I would be happy.

Is 150 degrees normal for these ESCs?

[Brushless55]

what about extra caps?

[ScarabChris]

Yeah the boat runs nice, I got a few runs that were faster than what you see there. The one just before it ran into the brush was very nice. I think it was over 55 MPH but for some reason the GPS lost signal.

[ScarabChris]

what about extra caps?

I would have no idea how to do that.

[blackcat26]

Just solder them into the power leads of the esc or piggy back em in to the original location where they are soldered. May help. Another member on here is running a pretty big boat and had to add some extra.

[Make-a-Wake]

Added two more 1000uf 35v's to my T180.............cooled the caps down a fair amount.

[ScarabChris]

Interesting.

I think I need to get this eagle tree thing-a-ma-jig so I can see whats going on in the system before I start altering things.

[ScarabChris]

OK after some tinkering the winner is............

I bet 2p solves it.

Yes running 2 packs per motor solved the shut down. I did swap the ESCs and the same ESC is still getting hot, over 150 degrees, but no shut down.

I can only assume the problem was that the motor and ESC was sucking the juice out of the battery so fast that the ESC read it as low voltage and went into LVC protection.

And despite the extra weight of the batteries the boat hit 57.6 MPH! I am sure this is already a 60 MPH boat as I clocked that 57.6 in short bursts of speed, less than 100 feet. If I get into an open area where I can hold full throttle for a little bit I am sure it will pass 60 MPH.

Man the boat was running so sweet and stable, I guess the extra weight made it ride more stable.

I was alone again today so no video, but I will get a video tomorrow and post it.

For now......

[dasboata]

nice great to see you got it worked out

[ScarabChris]

OK....I got another video on Sunday. But thanks to my wife its only 30 seconds long, just one pass by at 57.3 MPH.

Apparently I was in the way so she stopped recording and started over again. Unfortunately the 2nd video with the good footage never got recorded.

I did some sweet fly by runs and on the last fly by the boat flew out of the water again and ended with a spectacular end over end crash! I was so excited I got it on video so I could show it here. Then she gives me the bad news!

The good news is the only damage to the boat was the steering servo mount came lose. The bad news is that mount coming lose prevented us from recording the run over again.

Its always freakin something!!!

So until next weekend here is the short run.
