Aeromarine Sprint Cat .80/.90 twin 1717's

[Chrisg81983]

I have a t-180 running a 1717 on 6s2p with a 450/3 and no problems what so ever that way. The only times I have problems is when I try to put 1p to each 1717 they need to have a 2p setup unless you stay on the small side for props but that's a waste of the 1717 IMO as the 1717 can turn a pretty big wheel. Doing twins will also help take a little stress of the components.

That has been true for me as well ...meaning that I have not had any trouble with the T180s when I'm running 2p. I just don't like to do it because the boat is a lot heavier with twice the batteries, making it feel sluggish and with 1p the batteries aren't getting hot and runtime is good ...some 3300mah packs instead of 5000mah packs would probably be perfect.

I actually tried the sky lipos 4400 mah 40 c and they work great as a 2p setup I always ran Hyperion cells along wit thunder power but I must say I was very happy with the sky lipos even more than the gens ace packs

I have a few changes to the set up, I now have two monster 240 speedo's for this boat to take any worry out of way, one day it might see a motor swap out and 8s2p x2

Back on the table. Today I managed to get most of the noisy jobs done within daylight hours, after three days on a bobcat I gave myself today off to get some work done on the cat.
New plan.....................





Just Kidding.
I managed to get most the dremel work done to clean up the hull before finishing it off and added some more water cooling to go to the esc's.

You are sick ! Lol what are you doing with the gas setup ? I sold the twin 1717 setup I had for my sprint cat. I am now using a 2028, but won't be finished for a week or so. It looks really good, and glad to see you are back on the project. I thought you lost interest in it for a while.

I am thinking of doing a twin cat build in the future, I came across your today and the funnt thing is I was saying to myself the other day, what if I put the motors closer together instead of in the sponsoons and used struts instead of stingers, and boom theres your build and a nice one it is. All the ones I have seen have been the other way, is the way your doing it as common, with stuff closer and does it work well that way. It sure seems cleaner and probally the easyest of the two methods. I was wondering if there could be problems with the props being that close. I want to do a twin cheetah at some point, so any info on this topic you or anyone can give me would be great thanks.

I got some more sanding done and knocked up a center hatch lock to help hold the lid on. The hatch bends up at around this point so I think it'll work well along with a couple of pins in the front and the rear battery tray/ bolt down point, I can't see my hatch flying off in a hurry.

If anyones interested in finishing this project please contact me via pm. Please remember this is not a cheap hull and has been reinforced with carbon fiber, all the electrical components are brand new, it has new installed Speedmaster and Aeromarine hardware, a james williams custom twin 1717 motor mount fitted, a set of Dasboata worked stainless steel 5017/3 props(b&s and cutt back to approx.47mm) and much more. The layout has been designed to maximize space and COG adjustment, it'll be a very fun and fast boat but I'm looking at larger scale. This build has cost over $2100au so far but I'll be willing to ship it anywhere in Australia for only $1700au, you'll save well over $400 for all my hard work, lol.

I'd suggest putting this in the For Sale forum, a lot more folks will probably see it there.

thanks fluid, I'll get a sales thread done today, I ran out of time last night, hey you'd have this thing flying in no time, lol.

After a long break and a few life changes, this boat is back on the building table. I have priotised my time better and can spend an hour or two in the afternoons (between customers) working on my builds. The cat now has the driveshafts fitted and over the next few days I plan on laying up the carbon/kevlar to pretty and strengthen the interior. There isn't a lot left to do but I'll only be doing what I can, when I can, I'll keep you posted.

First update pic in a long while. I've installed the driveshafts and began laying carbon/kevlar cloth to finish off the interior.
