I found the easiest way to get the stock motor out with the drive in place was to use some needle-nose pliers and a bit from one of those multi-bit screwdrivers. For me it was harder getting the new motor in because I had to enlarge the screw holes and shave some material off the drive to clear the hex bolt heads I used to mount the motor.
Ya, i was going to do that, but I'm kind of fixed on doing a really clean job with balsa mounts and all that stufffffff, so that someday i can sell it and start a new tear into.

Sounds nice. What are you treating the balsa with to make it stronger and/or waterproof? Light ply might be a better choice for strength.

Either way show us some pics when you're done!

Not sure, maybe some sort of heavy varnish. May actually use ply, depends what looks best for the job when i get to the LHS. Not sure how i would precisely cut ply. With thin balsa i would just use a sharp hobby blade.

Will post pictures for sure!

You can cut some of the thinner ply with those big kitchen scissors, but if there's a woman in your life, don't let her catch you doing that!

Also a dremel with a cutting wheel should cut the light ply pretty easily and precisely.

Get one of these. I had a set with different size jigsaws but misplaced the other four over the years.
With this you can easily cut plywood.

I use a big tin snips and cuts up to 1/16" and doesn't splinter in cutting and is accurate.

Well, here's my version of the "Little Jet Boat That Could".

Out with the old....


Servo positioning. Mini servo from my helicopters throttle.


HK 4900kv KD brushless & servo mounting points.
I too persevered with the screws to remove the old motor & used hex screws & an allen wrench to reinstall the motor.


The drive is glued in so well that I felt that the screws were not needed. Just more drag. I also removed the plastic strips across the grate to improve flow.


Jet nozzle with new thicker steering rod.


First fire up & servo centreing exercise.


This will be my layout once I install a battery tray. Just going with 2S 40C 2200mAh.


Close up of layout. I'm using a Mamba micro pro for testing & will most likely get a 60A water cooled Turnigy ESC http://www.hobbyking.com/hobbyking/s...idProduct=7360 & cooling jacket. http://www.hobbyking.com/hobbyking/s...dProduct=12689


I used a Traxxas Rustler rx box . Everything has been double sided taped in. Servo, switch, rx box & ESC.


I have a mate that uses perspex a lot to make Baja 5B windows. He's going to sling me a piece to cover the hull under the drivers which I'll velcro on.
I need to fix a piece of ply in front of the motor & will use velcro to hold in my pack.

Video will come once complete & fine tuned. :-)

Capt Kirk controller, battery, everything that come out, lol. I said mate, take the box, but he wasn't interested.

Thought I'd at least get 2 bucks, but na, sold for a $.

Your boat is coming along. Don't test that little mamba too long. I use the 60amp from H/K too, faultless.

Seal her up good. Perspex lid is good under the canopy. Grate protects and really does not inhibit flow if made correctly.

Nice and clean looking setup Mozzy, looking forward to seeing it rip! Waterproof everything, even if you think it will be sealed up... water will get in.

Yeah, water has a way of working into everything these days.

My Genesis even gets water in it.


Where do you use yours 10x8, got footage?

Looking good! You may want to mount the battery sideways to get the balance further back. They need some weight in the back to keep the pump primed.

Thanks for that bit of info as I was debating how to do it.
