1/6 scale Jetsprint boats and 30mm Jet drives

[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.

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!

Is this jet unit able to go in reverse?

No reverse bucket, no reverse.

No reverse bucket, no reverse.

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

[Fella1340]

I only learned it through this thread and comparing options. I didn't think it was important option to have and I think it would require another channel on the radio anyways.

Because electric motors are able to change rotational direction without a transmission I bet if you spun the impeller in reverse you would be able to go backwards a bit. But who is using reverse on an rc boat?

From all the times I wired up the motor in reverse, I do not recall that the boat ever reversed. I am sorry to say that if you wanted a boat to go in reverse then this jet unit is not for you. Please I say that in utmost respect because I would hate you getting anything that doesn't fit your requirements. This unit requires 3 channel radio, so you can trim the boat as you go, also mix the trim function in with your steering, so when you do a steering input, the nozzel points down by a few degrees , pushing the nose back in the water so it turns better.
Remember , No power, No steering!

Great info as said most R/C boats would not require reverse it was more of a I wonder type of question.
Keep up the great work Mick!

what type of servos are currently using?

[mickieb49]

Hi I am using hitec STD servos, even micro servos would have enough grunt to be used.
I just moved the c of g backwards, helped a heap, one of my mates was filming, he will post the video later on.
Cheers mick

Hi Darin, just pm me with your postcode, state, town/suburb. And I can get a quote for shipping.
Just got a quote the other day to send a hull/jet unit combo over to the states and it was $85 AUD, I will add though if the actual cost comes back cheaper then I will refund the difference in full.
Still finishing off the cowl mold, so it may be a few days before I can get a hull completed.
Regards mick

psy.jpgpsyc.jpgpsych.jpgpsychot.jpgH Guy's, Just a little update, just got some paint on the hull, and the first 2 production hulls will be ready to ship out to some lucky customer in the next few days, by t he way these will be up for grabs.
Got the skipping sorted, changed the C of G and removed the lower lifting strakes, will get some video soon
Cheers Mick
