Pro Boat Formula Fastech Jet Drive Project

Is this your 1st brushless jet? Maybe that's why you never needed a turn fin. They will help out a great deal if you install them!

Brushless

Diego;
Yes it is my first brushlessjet. I have a Dumas short stuff with a mini jet and 11T brushed motor. Then there is the Aeromarine Challanger with twin 30mm jets powered by 550 monster motors 19T.
I'll try the turn fins. It just seems wrong to put fins on a 0 draft boat !!! I have run 2 real jet boats and had no such trouble. The Hondo 21' had a 455ci, 650 double pumper on a high rise intake manafold, and other goodies on a Jacusi Jet (sp) She would slide right along at 65mph and stop on a dime when you dropped the diverter and give you 5 cents change. Of course it would stuff the first 6' of the bow in the water. It was exciting though!

I have no idea what I was thinking. I am still waiting on Meniscus and the ESC...

Diego I will hold the props until he delivers!

You aren't waiting on me!!! Rather, you were waiting on Jeff!

I've got it today though, ready for transfer.

hey viking i had the same problem with my mini-jet-v it has a lot to do with wight and the hull shape . if you have a mono type hull large deep v in the front and a shallow v almost flat in the back then the 180 turns are going to happen . the only way i fixed it was by adding ride rails to the bottom on the sides .

but anyways good looking boat . hate to say it but i agree there are going to be some issuses when you get up to speed . mite wont here a little nose heavy . that will help. cant wait to see what that 40mm will do . been thanking i wont to play around and put the nozzle on a 29mm intake . but hate to spend the almost $100 to get the drive

[Meniscus]

...and put the nozzle on a 29mm intake...

A nozzle? Please explain, I'm not following.

[DRAGONFIRE81M]

on the 40mm drive its gray. witch is the impeller housing ,stater nozzle and steering nozzle on that . we just call it the nozzle on rcu sorry .

but im talking about transplating the "NOZZLE " of a 40mm to the intake of a 29mm witch is shorter then the 40mm

Excellent post and build Danny , keep up the good work . I have been sitting on this for years collecting dust hoping to one day run into a 36-42 inch flat botton hull . It would make a great Sunday driver . the jet drive I bought on ebay 4 years ago as a limited run miniature berkley jet drive and the motor is a Plett 355/50/06

[DRAGONFIRE81M]

thats pretty cool what are the dimentsons on the drive ??

[Punisher 67]

2.15 inches in diameter x 8.5 inches long just for the pump itself , with motor and coupling it is 15.0 inches total length

[Diegoboy]

Thanks for the input Guys. Do you have a link to that jet drive? I'm almost afraid to ask what it costs

[DRAGONFIRE81M]

from what i have seen around i dont thank they make them anymore and are consiterd an antice . but could be wrong . i have got plenty of bad advice

[Diegoboy]

If it is in fact an antique, the the price could easily double

[Punisher 67]

They were a limited run and only 16 were made , I don't know what its worth now but it cost me 325.00 new . I don't even know who made them it was an ebay purchase from the guy that made them.................

Peter, as usual you have some really neat stuff. That drive looks like a piece of art.

that drive looks almost exactley like a real 1.1 jet boat drive...that hood comes down over the thrust flow and deverts the flow towards the front of the boat for reverse
