JAE mini sprint 109$

I think the 3500kv on 3s could rock real good!

has anyone tried it yet? I know the kit is relatively new...

I am in the process of building mine right now. I haven't bought a motor yet and was thinking of going the 3500kv'ish and 3S. I know that Zipp has recommended the 2200mAh batteries, but does anyone know what the max battery size that will fit in the hull? I would like to get the most mAh as possible for the amp draw head room.

Thanks
Mike

Mike,
I spent some time last weekend trying to see if I could fit a bigger battery in than the 2200. The issue is the batteries start to get to long and hit the shaft as it bends up to the motor. So, the best I could find was the 2200. Others, may have found something I did not, so we will see.

OK, thanks for the reply. I wanted to put an order in for batteries and a motors from Hobby King soon. Looks like I will be sticking with the 2200's then.

Later,

Are you getting 2200mah 3s battery in with the esc ok or are you having to put the esc some where else & not on top of the battery as my esc (not the Zippkits esc ) will not go on top as it stands above the tub. Thanks Martin.

I have not tried the 3s so can't tell you. I did try putting a 3s 3000 in there and no luck. To long. So long as the length of the 3s is not more than 5mm more or so than the 2s and it is just a bit thicker it should squeeze in there. Just a guess though.

I found 3s 2200mah wont go in with esc on top of lipo,The tub depth inside to under the lip is 32mm.A 3s is around 24mm-26mm depending on type.That only leaves 6mm-8mm for the esc,My esc is 15mm so no go.A 2s is only 16mm deep so leaves 16mm for esc so is ok. I built mine to run 3s so will mod the tub deck by fitting a second deck raised up 8mm with a slightly steeper curve at the front of the deck. With the cowl sitting on the raised deck. Martin.

I did recall seeing a picture where they had put the esc to the side of the motor. Turned on its edge. I am using a left over 120amp esc I have so that is out of the question, but thought I would throw that out there if you had a smaller esc...

I use 60amp watercooled esc on my micro boats as i do run quite hot setups on large props, But even on say an air cooled esc which they sell for this boat i think youll have problems getting 3s + esc in. Along side the motor theirs only 10mm & thats touching the motor so out of the question on an outrunner with the body spinning. Unless your using a very small low amp esc i think your going to struggle getting 3s in. Like i said im going to mod mine on top of the tub so im not going to be craming everything in such a small space on 3s. As well as its a very simple mod to do. Martin.

[Turbo Dan-O]

Which $12 outrunner?

Haha...I am still trying to figure this out! Spill the beans Martin!!!

[martin]

Haha its a mystery !!! Martin.
