Thought id see more posts on JAE mini sprint??

[monojeff]

Surprised I have not seen more people talking about the mini sprint or showing build pics and info??

Who's got one and who's building one?

What setups are you running?
Anyone running or plan to run a different motor combo then used by zipp?


Post some pics and videos!!

I am building one, first boat in a long time. It was going to be a genesis, but didnt want to spend that much coin at the moment. I got nearly all I need for the mini sprint on hand and always wanted a rigger so thats it. I would like to say thanks to those responsible for the plans. I may modify to fit lipo.

My setup;

scorpion 2221-4400
50amp esc, cheapy sitting in my draw.
servo HXT9g
2200mah 3S 40C

Anyone dare to recommend a prop?

[monojeff]

Sweet, I also plan on using some xtra stuff I have around.
I have spare wood from a 1:10 scale I'm working on and a traxxas 380 4000kv motor I think I might try out.

As for props I guess start with the 427 and work your way up??
Do you plan on starting a build thread?

I still have atleast a month till I think I'll be able to start mine which is why I started this thread trying to get some inspiration.

I started cutting tonight. I felt a bit guilty after I wrote that I had started building, when in actual fact I had only printed the plans. I have got everything I need except a stuffing tube, shaft and prop. I ordered them from OSE a couple of days ago. I will make my own rudder out of stainless sheet or mill out of alloy if I dont like the stainless one. I made templates of the tube and sponson sides. I have two sons and a few nephews and can see these will be popular.

I have been running mine for about a month. I cheated and bought one pre-built. The thing is a blast to run. I am using the original recommended turnigy 4400kv with a 2200 2s. Boat handles great and a nice speed to it. Turns on a dime. My only issue is the drive shaft it comes with. I have three of these boats (one prebuilt, and two I am building) The first shaft came apart where the flex goes into the solid part of the shaft(lost the plastic prop, no big deal). I then "borrowed" a shaft from the second build and it just did the same thing this weekend. I am going to grab the third shaft this weekend from my other kit and see if it also does the same thing. Luckily, the props are cheap.

I am slowly putting mine together. I bought 2 kits from Zipp when they were first released. Since I couldn't get the 4400kv motor, I went to a 3700kv and 2200 3S packs. Should be close to the same performance. Should be fun.

Later,
Mike

You may want to give Joe at Zipp a quick email letting him know the stub shafts are coming off of the flex. If I know Joe well enough, he would want to know if there's a problelm so he can get it fixed.

You will deff be faster on the 3700kv & 3s than the original 4400kv on 2s. Martin.

I havnt used the original shaft & tube but the stub looks like its bonded with some sort of glue rather than a Loctite 603 type of retainer as theirs a bead of glue where the flex comes out of the stub. You dont get that with Loctite retainers as it dosnt set like that in the presence of air Im using 2 ball bearings & a wire drive in mine for less friction. Martin.

Sweet well post up some pics guys!

I look forward to getting mine going.

I will be making a wire drive eventually. I am going with the flex as this is my first boat in a long time and I wanted plugnplay and foolproof.
Is your shaft stub 1/8?
Did you harden it after you made it?
What did you make it out of?
What size wire did you use?

Thanks

EDIT* Also what plastic prop and where from?

[monojeff]

OSE sells drive shafts that should work for your purposes.

What do you guys think about just gluing the carbon tubes into the sponsons? I dont have any tube that will slip over the carbon tubes on hand.

Go to your local hardware store they will have some brass or aluminum tube it is cheap.
If you glue them and they break you can't replace them since you glued them into the sponson.

Mines up and running with the stock setup and it's a blast, I have the 3500kv motor and 432 prop coming to try out and see.
I also found a set of 4 props on ebay 27mm-35mm for $7 to play around with.

Here's mine next to the JAE12.
