31" challanger offshore build... very unuasual power

[skidooguymxz550]

big update time!!!! i got the motor back so she was running again. i also got a video of it that i'll upload on monday when i get home.

this morning i ran it and she was running great...... till it blew up!!!! yes blew up!!! i was about 4 minutes into the run and i heard a boom and the hatch blew off (little tape held it on) when i brought it in a battery had blown up. i found it odd becuase the other electronics and batts were at a normal temp... what would cause that?

heres the cool part, its on video:D

I would say a bad cell! or you simply pulled more than bat can handle!

yes. my moms a terrible camera person. i told her keep it on the boat

[Old Sloppy]

with the diferrent motor and controller will i get the same speed on land? i broke into the 70's with my tc4 on the maxx

Did you know 40 mph on the water = 100 mph on land ?

I learned this at a professional boat race many, many years ago.

so 70 mph on land = 28 mph on the water.

Harry can you explain that a little deeper by telling how to you came up with that calculation?

I just got done reading this thread, nice looking boat. So you are running the HV-maxx without problems? I never got to see which HV-maxx it was. The original 4400kv motor or one of the new ones. I wanted to install one of mine in a boat, but I sold them cause I never thaught they would perform cause of the high RPM.

Also, I have a mamba maxx 5700 combo, I thaught about putting that in something small like a bby 21", or a small fuller hull. Still not sure if the KV is to high or not...IMO.

The video looks good, that thing flies! needs some trimming though ;-)

[skidooguymxz550]

no problems at all except one fried because it got wet. they are pretty hot to the touch after a run but it was the same deal in cars. yes it is the 4400

thanks for the boat compliments. she goes pretty good in the vid but she goes to the point were she'll blow over in calm water
