BJ 26 Upgaded Hardware!

[txboatpilot]

Here are a few shots of my new BJ26 with fullers catamaran hardware and other simple modifications!:D This set-up ran much better than the stock out of box. No gps yet but I would est. speeds of 40-45mph. I am running on 2S2P 4350mAh Polyquest lipo's.. And for max. run time I use 4S2P 3700mAh Polyquest lipo's!!

1. Fullers Cat Hardware w/ .150 f/cable and 3/16 to 1/8 prop shaft
2. Remove spin fins and drain plug, (filled holes)
3. Moved Ant. mount to the rear
4. Removed radio box, but reused the wood servo tray (put tray in place of radio box, had to make new linkage for rudder)
5. ESC was moved to center in front of the motor, power wires shortened (mounted w/velcro)
6. Receiver moved and coated with (3M DP270 epoxy)
7. Hatch (filled in hole where ant. came through)
8. Use OSE tape for the hatch to keep water out
9. Prather 220 prop (balanced & polished)

All these mod's helped with turning, stability, smoother driveline, and helps keep the water out! I had fun testing this boat in stock form, it did well. Now it just performs GREAT, and after 5 min of running hard, esc and motor temps were below 90 deg. and 100 deg. on the batteries!! I will keep it around for a while!!!!

TX thats the kind of the setup I'm looking for can you point me to which fuller...I want a rudder like the jolly to make it look more scale but what the heck....that inline rudder i like....looking good kid.

Here is a link, hardware is about half way down the page..

I almost went that route. But insted I bought a strut and offset rudder setup. The strut showed up today, hopefully my rudder assembly will be here tomorrow. The stock drive has pretty much gone to crap.

I had both off-set and this laying around, so I tried this for steering in both directions.:D Post some pict's when you get it done! If you start running on lipo's and prop up, the stock drive system will not last. The stock unit is also flimsy and the u-joint is a JOKE....

[obrien]

lol I know what you mean. The stock drive system is falling apart already. The stock universal was getting very sloppy so I put a new cable and univeral in, that lasted 2 runs before the universal almost came apart and the cable started to unwind. That and the keeper for the vertical pin on the drive is now gone.

obrien a flex upgrade is cheaper than buying a replacement uni joint drive.

[txboatpilot]

U-JOINT DRIVES SUUUUUCK!!!!! IMO,,It is one of the biggest flaws in design, that a RTR Brushless Boat can have...

[RCprince]

I had the replace the original one after the first 2 days of running, the second lasted me 2 runs, then I saw deigoboys upgrade..that was all she wrote...the flex is SOOOOOOOOOO much more efficient....Proboats Engineers need to be beating with a couple of those uni-joints as we all yell "NO MORE U-JPOINTS"...80's quackology

[Diegoboy]

Thanks!
It's (flex shaft mod) more efficient if you keep the steerable outdrive.
Nothing beats a good HW replacement though!
I'm going to replace mine after the holidays

*edited for clarification

[txboatpilot]

Diegoboy Thanks!

How is the sterrable outdrive "MORE" efficient??

[RCprince]

What he means if your gonna keep the steerable outdrive the flex set up is way more efficient , the uni joint is out of balance, try reving the motor with the u-joint then do it with the flex cable install...with the flex cable it sounds smooth, with the u-joint it sounds like the boat is coming apart...

[Diegoboy]

What I meant to say is...

If one chooses to continue the use of the stock steerable outdrive, then the "flex shaft mod" makes the outdrive more efficient than the stock U-joint.

...but nothing beats the installation of a good set of hardware which I intend to do as soon as the holidays are over and I recover from the financial burden it has caused.

I hope I'm more clear this time. I'll try to do better next time.

[txboatpilot]

I got you! I was corn fused!

Na, I re-read my post, it was misleading. That's why I edited it. Sorry:blushing:
