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

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.

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

So now officially the hulls are ready, It will take a week or two before I will have a few hulls made , but I am now taking orders.
Hull , Jet unit, roll cage, dummy drivers $300 USD for the kit plus postage.
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
Regards Mick

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.

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.

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.
