Do your jet pumps have a reverse cup

Hi, no they do not, they have turning and trim.

Ok guy's, just had a run, will post some video up on Youtube tonight. Went better than expected, so officially they are for sale , $115USD each plus postage.
Please note you will need to put these together yourself. Either PM me here or send an email to : mickieb49@bigpond.com.
Please include your address in your email so i can get a shipping estimate to you promply.

Hulls will be a few weeks off yet.
Regards Mick

Here is the video, was very happy. May be too small a hull though as it was very twitchy, my hull will be 610mm , should be more suited to this unit.

Hi Guy's,

Hi Mickie. Do you have any plans on incorporating a reverse cup on your drives ?. Thanks

Hi Mickie. Do you have any plans on incorporating a reverse cup on your drives ?. Thanks

Hi Mate, as of yet i do not, i do have plans on adding a second stage though, but this may be a few months off though.
A reverse bucket on these little boats is mostly for looks, i have been running them for the past 10+ years and not yet have i needed one, will take the idea on though. It will complicate the whole rear cone/ trim arrangement , not to mention the extra cost on setting up another injection mold for it.
Thanks for your interest
Regards Mick

Hi guys, here is the finished plug20131207_163206.jpg20131207_163213.jpg20131207_163222.jpg20131207_163228.jpg

Will keep updating pictures as I get some progress.

Lookin good Mr Mickie, was that one done using the router ?

What size is that one buddy ?

Chris

[mickieb49]

Hi chris, yep it was CNC'd out with the router, sure beats doing it all by hand. Hull is 620mm long, have also started plans for the marathon river race jet boat hull, maybe have it routed out early in the new year.
So you found me then?
Take care and hope your well.
Mick

[F1roddo]

....... yep, I found you.

Keep that router going buddy, its all looking real good from here on in.

hull2.jpghull3.jpgHi guy's, just a quick update,
Molds are done, well I had to resize the hatch plug so it fits better, but I have the first out of the mold and have started to fit it out , hoping to give it a run Friday the 20th, should be releasing them after the run.
Cheers all Mickhul6.jpghull.jpg

[F1roddo]

I guess the router is working well MickieB ....

Hull looks pretty good buddy, look forward to seeing the difference between this one and the smaller one, when you get it runnning.

Cheers
Chris

Hi Mick,

When you get a break in the action, please show the bottom of the hull with the jet pickup side shown. I want to make sure I get it just like you want it. Man the your Hull really is nice and easy on the eye's. Looks like it will take ruff water pretty good.

Best,

Mike

[mickieb49]

Hi Mike, as requested

I will have a instruction sheet for the installation of my drives into any hull available in the coming days.
Thanks for the kind words on the new hull, I had to go back and re CNC out the cowl plug as the sizing was all wrong, so hoping to have the molds for it done this week. It should be a perfect size for this jet unit, and still be quite lively ...
I will update more pictures tonight, Regards Mick

[Mike Caruso]

Thanks shows me what I wanted to see.

[mickieb49]

heres the latest, nearly ready

Looking sweet!
What's the roll cage made out of?

[mickieb49]

Hi Jeff, the rollcage, is made from 10mm alloy tube with CNC'd clamps, these will be included in the hulls. Just need to get one to you so we can work out the sticker kits.
I will upload the video of the hull after Wednesday, providing all goes well I will release the hull/jet unit kits this weekend.
Regards mick

[monojeff]

Looking forward to it!
Btw we need to make some guage cluster decals to go with the kits.
Thought it would make a great addition!
We should also figure out a logo for you.

[mickieb49]

Hello All, just ran the little jet, pretty happy with it , will upload some video when i get home
Still have to play around with the COG and Trim but overall it performs very well and isn't as twitchy as the shorter version.
Jeff the idea on the guage cluster decals would be great, i will try to get the hull and unit over to you as soon as possible, i will also send you some pictures of the real Jetsprint Boats that race here in Australia, so it gives you something to follow off.
Please stay tuned as video will be comming up.
Regards Mick

[mickieb49]

Ok guys , here is the video.
http://youtu.be/BIY6MBf0iiM

Hull on it's own is $175 USD.
The Kmb/Kehrer hull/ jet unit that I tested the jet unit is also up for sale, you will need your own electrics, asking $250 USD plus shipping.
Take care and best wishes for Christmas

Nice boat is looking good for first time out!
How do you think it would do with a smaller motor like a 36mm?
Do you think the 40mm motor is necessary?
What is the optimal rpm for the unit as you have it now?

Hi Jeff, mate I think it might go OK, just it may draw a few more amps as a 36mm motor is typically not as powerful. But if your keen you may be able to test it yourself when you get yours.
As for the rpm, I have not tested it over 30000rpm, the efficiency drops off around the 28000 mark.
I am now looking forward to seeing what sticker kits you can come up with.
Regards mick

[monojeff]

Certainly will do some testing.
I bet it would run well with PSpec power.
It seams you have more then enough with the 4074 motor so I don't see any reason using a smaller motor wouldn't be ok. I wouldn't think amp draw would be much higher maybe someone else could chime in on that.

[TheShaughnessy]

I used to run a first gen SV motor ( blue can ) and AQ 45 amp esc in a 29 mm graupner unit. No actual numbers logged but that set up never got hot and it was In a 31 inch mono. Still working on getting some cash together before I can order one. Need a charger and radio first though. I have eagle tree so if I ever get one ill gladly post up some amperage numbers.

[Mike Caruso]

I am going to run mine with AQ 1800KV and AQ 60amp esc but I have ICE here so it will be awhile.

[monojeff]

I also have Eagle Tree and can log some numbers.
I planned to try out a Proboat 1500kv motor on 4s & 5s.
I think it will be a perfect setup for this given the size of the boat.
Looking forward to this a lot and I know they will be a big hit!

[monojeff]

Is this jet unit able to go in reverse?

[Fella1340]

No reverse bucket, no reverse.

[monojeff]

No reverse bucket, no reverse.

Thanks I didn't think it did but I am still learning.
