Thanks a lot, martin and wparsons. I think i´ll try the 4400kV motor wparsons mentioned above.

what would be a great 3s motor?

[wparsons]

Something in the 3000-3200kv range in the same size should do the trick!

I'm doing a scratch build of one, the hull and sponsons are done but I have other projects to finish before this one gets power.
Planning to try a Tacon 28mm motor, undecided on length. Not using the stock motor mount idea so I can play with positions.
I'm using aluminum C channel for a mount that spans the width of the hull and bolts in on both sides.

Got my pre-built mini sprint yesterday and noticed right off the ski isn't centered on the tub and it's cock-eyed. How critical is the ski position and will this cause a problem?

[Brushless55]

That's interesting....

[geraghty]

That will make absolutely no difference whatsoever to the boats performance......Your JAE Mini-Sprint will not care.....
Finish er' up and go run the boat.....:-)...:-)

Plus, it is centered and straight, it just bulges out in the middle. Your measurements at the front and back are within 0.3mm of each other.

Once again,that will be fine .....the boat will not know the difference......

If you look closely, it's actually out 2.4mm front to back on the left (37.1 vs 39.5)
and 1.6mm front to back on the right side (39.0 vs 37.4), therfore my concern.

It's all moot since Mr Geraghty says it doesn't matter. I need to get a motor and finish it up. Actually can't wait to get it in the water.

Can I just confirm that there isn't any hydrodynamic or aerodynamic reason for putting the 1/8th" basswood strips for the tub top on the outside? It's just for ease of building right? I think it would look a lot better without the overhang on most of sides at the top of the tub and intend to apply basswood strips internally and sand it off the outside if it's just for ease of building.

I think they're there for ease of taping the hatch on. Without them there's very little material to hold the tape.

Just ran my mini sprint for the fist time. Really ran great! Fun boat for a small pond and turns on a dime. I did clock some faily high temps 160's. Wondering on these outrunner's what is exceptable? More than an Inrunner? Here is a pic of the boat with it's big brother which I also test ran today. It did around 52mph, but has a lot more because I was testing in a very small pond near my house. Great for a quick test, but no room for error with a bigger faster boat.

52mph
holly crud, I did not think these were going that fast
