Super Hawaii questions

[Gexx99]

I dug up a super Hawaii hull out of the basement. It has only the outdrive hardware minus the gearbox. I was looking at putting a brushless system into it. From what I have seen in other posts I need to use a 180a seaking esc. I'm unsure exactly which motor to use besides a 540 size and the can should be 74mm long. I don't plan on running lipos with this. I have a bunch of nimh batteries at home. Was thinking about running 2 6c packs in series. I would like to be able to get this thing moving, is 40mph realistic? I do still have the original outdrive and would like to re use this. I figured I could link up to the stock system via direct drive. I understand this may not be the best setup, but I will likely only run it a few times a year and I am on a tight budget. I plan on mounting the motor in the rear section of hull using wood to mount to. Any other reinforcements that I need to make? Any help is appreciated. Thankx m

Nothing important.

Mine was kept in the basement away from the sun so it is still strong and not faded. I did some looking and pulled some info from other posts. I was going to use a 9xl motor with a 120a seaking esc. Hope it works. If I use it and it runs good, maybe I'll glass it and use a different outdrive. I have yet to see a build that uses the stock set up. I'm betting it won't last long.

Do not bother trying to use the stock outdrive with LiPos and BL power, it will self destruct very quickly. They were marginal with the stock low performance brushed motors and nickel cells, and handling at non-stock speeds was poor. Strip out everything and go direct drive with flex cable, surface strut/stinger and separate rudder.

Apparently you had a typo - were you going to run two 6S packs in series? That's 12S and not only expensive but way over the top for that hull. Running one 6S pack would be fine, and with the right setup 40 mph is certainly possible but don't use a 9XL motor. Whether the hull will handle that speed without falling apart is another question.

What I meant was I was looking to run 2 6 cell nimh batteries in series. I tried abriviatong not knowing what I was doing. Would that change my setup much?

In order to glass this hull I will need to cut the top of the hull from the bottom to make it accessible. What should I use to re-attach this?

[FRED]

Id better clarify myself alittle better.

The electronics pod on this boat is around the 30% mark. It is built into the top section of plastic. I would have to cut this out to re-enforce the hull. Looks pretty easy. No, I have not decided on a motor. I wanted to make it a brushless system. I'm not sure if this is the best route to take. The build post that I was reading never said how it turned out. I know that you said what you had used back in the day, but has something better come along since then? I think that I have found a lipo setup as you suggest that I could pick up a charger and pack for about $60. Probably isn't the best but better than nothing. The board option sounds easy but the other way sounds stronger. I will have to think about it some more. I guess I need to nail down a motor first.

This NQD Spurt is basically the same hull.................i guess from leftover molds...........

It still has the stock steerable outdrive...............it had a 700BB turbo in it first on 4s lipo and went around 25-28mph. This vid I have outfitted it with a 540 9XL and is running on 4s Lipo............somewhere in the mid thirties................fun boat.

That makes good sense. A 9XL on 12 NiMH cells would work great for you in that hull. I still think that the outdrive will not last long, and it is a large power drain, but using it simplifies the build. Strengthening the bottom will help with hull longevity.

questions

What ever route you take, i wish you the best. What i posted , are things of the past and worked, just trying to help is all.

What is the name of the 3m spray that you use? Is the 15 minute epoxy just any that I find or is it something special? Looking at ordering glass right now and want to pick up the right stuff.

[FRED]

3m is name of company.

[Gexx99]

I know that 3m is the company. They make a ton of adhesion products. I was just wondering which specific one I should use. Sorry for the confusion.

I just ordered a 9xl and a seaking 120a esc along with some fiber glass from hobby king. I think that I will glass the rear hull and transome. I will put in the stock drive setup, minus the gearbox, and run it until it breaks. Depending how much I like it after that, maybe I'll spend some more money on it. Once I start maybe I'll post some pics.
