Hey guys, here's a good place to post your RC boat action shots!
Here's my Graupner Red Rocket-

And here's some pics of my (highly modified) caribbean cruiser. It was an embarrasment out of the box, but now, with a couple of Traxxas Titans, an RC-Hydros ESC, and an Octura prop, it flies.

Chris, Are the Traxxas Titans 28,000 RPM and 15 turn? I am asking because I purchased the "already modified" version of the Cruiser which has twin aqua torque motors(28,000 RPM 15T 550s), larger pinion and spur gears,, and a modified prop. It does a good 28-30mph for about 18 minutes on twin 3200 7.2V packs.

Just wondering the similarity or differences in the two motors. It would not hurt my boat to upgrade after all... Thanks!

I don't know the RPM, but they are 21T motors. They push it at about 20-22mph. Are you sure yours is really going 30mph? That is a lot faster than it sounds. Also, the Titans turn between 25000 and 26000 rpm. I would HIGHLY doubt that any pair of 15t 28000rpm motors could really last 20 minutes on a charge. Mine usually lasts about 10 minutes between charges on 3000NiMH cells. Also, are you just getting those #'s off of the box? My box said 25mph plus with 20 min. runtimes, but when I timed it, it was doing 13.8mph and running for 14 minutes on a charge. Don't take what they say for granted.

Chris, I timed my boat with a friends radar gun but the top speed is real inconsistent. It will do 24mph one day and 28 the other. About a week ago it spiked 29.7 mph. I suppose it is because of the record low's we are having down here in Miami lately. I will wait for a fairly weathered day to get a good speed rating.

Also, the Titans turn between 25000 and 26000 rpm. I would HIGHLY doubt that any pair of 15t 28000rpm motors could really last 20 minutes on a charge.

I usually get an average run time based on full throttle 70% of the time. I usually don't juice it straight for the entire run time. I ocassionally let it cruise on the first speed and take some slow turns then take a burst of acceleration. On full throttle runs however, you are probably right, my batteries would last a flash.

I agree about inaccurate speed claims from the manufacturer. However, the Carribean Cruiser now comes with the hop-up kit that I mentioned earlier installed, so the speeds are obviously faster than stock. I will get an accurate run time on full throttle using my 3200mah fully peak charged and come back and post. Till then, Happy New Year!

OK, that makes more sense. My runtimes are WOT 100% of the time and until it noticeably drops in speed. If you want to upgrade, then you should definitely consider an ESC as the first upgrade. They are more consistent and have a much lower resistance than the stock MSC. After that, you can consider new motors. Happy New Year to you too.

Less resistance should mean more power left over for the hungry 15 turners right? Also, do I need to swap out the radio system after changing to the ESC? I have thought about the ESC before since the 2-speed stock MSC becomes boring and redundant. Plus it's ridiculous that Megatech includes a High performance ESC in their 9-inch H20 boat but not in the Cruiser.

Leaves allot to be desired. Thanks for any and all input...

I don't know what you mean by swaping the radio system....

but you don't need a new reciever to put in an esc, all you radio equipt. that you have will be fine
make sure you get an esc that can handle the 15turn..

[Chris LaPanse]

Suggestion - an ESC WITHOUT a BEC is fine with the stock radio system, but one with a BEC (at least the one I got) makes a LOT of radio interference. I would upgrade the radio anyway (I upgraded to a CRX, but any 75MHz FM will be MUCH better than stock). Yes it should be compatible as far as the plugs go, though. As far as leaving more power for the motors - I gained 2 minutes of runtime by switching. I would suggest for the ESC getting a WATERPROOF 12 cell ESC, preferably one designed for boats. It should also be designed for twin 15t motors or a single 7t motor (for twin motors, you multiply the limit by 2). If it is just designed for just one motor, then hook them up in parallel, if it's designed for two, then you can just hook it right up. It should give you a small increase in speed as well because of the lower resistance.

[scorpien boats]

wow you can do that? even if the esc is only made for one????

oooo that gives me some ideas lol

[Chris LaPanse]

Yes, as long as you double the minimum turn limit or voltage. This means on an ESC designed for a single 9 turn motor at 14.4 volts (12 cells), you could either run twin 7.2 volt 9 turn motors in series or run two 18 turn 14.4 volt motors in parallel to get full speed out of the motors. What you can't do is run 2 9 turn 14.4 volt motors.

lookin good :cool:
