I have one of these in a 1/4 scale jet boat of my own design and build they are a good unite but need some mods to make them work better for longer first mod is drill out the brass bushing and replace with a 10mm high speed stainless steel bearing second mod pull out the stator and drill out the where the grub screws attach to the stator to hold in place so you can then put longer grub screws in that hold the stator in place better as if you get a bit of weed or a tiny rock the sator comes looshttp://www.youtube.com/watch?v=33TK2isWBDg&feature=context-gau jet boat I've built using one of these jet drives great fun to drive. Running 56/82 1050KV 4 cellDisappointed in this unit needs more engineering work. mine leaked had to use silicon and the sator came loss can't believe it's only held in place with grub screws and hot fully screwed into place for such a powerful unit I don't think I'd buy another one might try KMD jet drive next, also It's been a challenge to set up with electrics as our lake doesn't allow petrol. after a lot of messing around I got it to work but only short bursts at full power I'm using a 56/82 1050kv with a 8mm shaft 180amp speed and 4cell 5000AMH lipos. It is only producing full power for 2-3 seconds then drops any ideas on what might be happening ???It arrived after paying the douane in the Netherlands .
When i opened the box , i was a little bit dissapointed .
There was a gap between the 2 halves of the JET .
Near the bearings the gap was more than 1mm .
I measered the gap and took a knife and sissers and made a gasget 0,6mm thick .
I sealed it with silicon and so it fits and seals perfect .
Bearings are now good in place .
I will use the JET with a geared 49cc .
15000 rpm on the jet 10000rpm on the motor .
Motor is a tuned pocket-bike (gag ) engine 49cc .Hello all.
I have 2 of these pumps.... one of them is for sale if you cant wait for stock to come back in.
untouched in box ! ..... have no need for the 2nd one as my twin project is no more.
$260 US shipping ?
have received 1 of the 2 pump i've ordered, very impressive looking unit still constructing hull, so I can't check for leaks yet, impeller spins freely, as mentioned by someone else the screws conecting the grate to the pump would have been better if they we're countersunk, but that can be overcome. overall a very good unit (just got to get my hands on the other one).Received mine too, the finish is ok. The strengh of the hull is 2mm aluminium. The scews on the bottomplate are still not countersunk, but you can easily make them. Sadly the hull is not 100pcnt waterproof, you have to disasseble the jetdrive and make some sealing. But still, the overall quality of the drive is ok, but for the price I expected more.
here some pics of the drive and impeller
h**p://img190.imageshack.us/g/img0498bd.jpg/Have just recievied my jetpump. Would have given it 5 stars but there is no instruction sheet that should have an exploded view with all relevant parts & number. The unit is very well made and looks more impressive than the picture posted of it. Perfectly finnished and spins over smoothly by hand. All parts fit and move together very well. Highly rate this item. Well worth the long wait for it. Hope parts will be available.
Need spare impellor & stator for any misshaps. Well done HK. A fine bit of CNC work.
