On the starship I cut very thin slivers of the foam and put them into the sponsons. There is a lot of room on the right rear side of the hull for a sizeable chunk there. I also slice a fairly thin piece and glue up under the hatch. More room there than you think....behind where the battery goes.

That rigger is made by Tenshock. We are the dealer for it here in the U.S. There are dealers in Germany and apparently also in the UK. The Tenshock motors are some of the best in the world, winning a lot of naviga races. They are not popular in the USA because they are rather expensive and unknown here. The esc's are also made by Tenshock. The servo is a well known brand, GWS.
Anyone using one of these? Someone linked me to one, not too keen about what electronics it comes with but 50+mph with a no brand ESC and motor is impressive for something so small.
I don't really know what is good and what isn't in the boat world when it comes to hulls so would like some advice here...
If I was to buy one what would be a good replacement for the motor and ESC, what kind of prop am I looking at?
If its not too great, are there any other small riggers out there which are good for a beginner?

I am assuming that if one does all this it will float flooded? I had not thought about slivers of foam in the sponsons. Instead of a Starship was thinking of a mini eco, cheaper, looks to be fast and it stays afloat even if it flips, self righting too.
Sailr would you care to comment on the pros and cons of both designs and potential speed. I would hate to loose another boat due to lack of flotation and poor hatch sealing.
Must say I did like my Starship though, very fast and stable.
PM me if you would rather discuss offline

It doesn't take much foam to float the Starship. The boat is very lightweight.
The Mini-ECO is a totally different experience. It runs flat and makes 90 degree turns. It's a blast. It is not as fast as the Starship obviously because it is not a rigger. It is a subsurface drive also. The Mini-ECO is in the 35-40mph range.
For speed, the Starship, for manueverability, etc, the Mini-ECO. Personally, a pond full of Mini-ECO's would be an incredible blast!
You do have to 'tweek' the ECO to get it to self-right. It's all about enough weight on the left side. In the instructions we show you how others have opened up the deck and put some lead weights in there. If you run a bit heavier battery, like a 3000mah, that's probably enough weight on its own. The ECO has the flood chamber. When they are manufactured, they have the minimum amount of venting, allowing the user to customize the self-righting feature.
It's really your preference.Mini Cat Racing USA

I placed a fine layer of cf covering over the boom arm entry holes from within the hull... now have two water tight air chambers for flotation.Wayne Schutte PhdCSE BaSE BaEE. Australian, & damn proud of it

The rigger that my buddy bought from the swap shop here had the sponsons blocked off with glass. I has saved it a few times when the hatch becomes undone. It also helps to lightly sand the taped areas with 2000 grit just to knock the shine off. The tape stick much better.If all of your wishes are granted, many of your dreams will be destroyed!Comment

Correct, if you close off the small area in the sponsoon with silicone or such you trap air in there that is just enough to float this little rigger. On another note, the Starship is a wonderful rigger. I love mine and can't say enough about it. It runs flat and fast and didn't take much effor or knowledge to get it up and running. I'm spending more time trying to needle balance the small prop than anything else on these small boats.Comment

One of these days I'll snag a Carbon Starship, they look so nice.
How much is a Carbon Starship without power system, just ARTR, with servo & hardware installed? I have tons of motors & esc's in this range.

Currently here are the prices: http://www.minicatracingusa.com/srigger.html
Carbon Fiber for $419.00
I have the non carbon one as love it to death. I have quite a few 2040- motors and so far love the way it runs with a 3800kv and 34mm 32D prop. with 1800 battery.Comment

Love those CF starships. I added a turn fin to mine and it greatly improved handling. Pics show how it was done. Also have flotation in front and sponsons. When putting a bigger, heaver motor, like the one shown, I added some ride pads formed from balsa and sealed/painted white. Does two things, gives a bit of needed flotation for the heaver motor and permits a nicer air flow under the hull at speeds. Mark Grimm recommended this trick to me and it has worked out well.Comment

Cool way of adding the turn fin did you fabricate the holding bracket or purchased it as a set with the fin?Comment
-
Thats the first time I've seen a turn fin on the transom of a rigger.Comment

Agreed!.. BUT, the CG of the CF starship is 5 to 6 inches behind the back of the front sponson. Most Hydros have the fin here but it may be too far in front of the CG. A trick I learned from Mark F is to put the turn fin at or behind the CG. This is why when you look at his Insane Hydro the turn fin is actually way behind the sponson on a long, heavy duty extension bar.
Anyway, seems to work for me............I will get Tony to take a video of it running the next time he comes down.Comment
