Taming my brushless Mini V

[wparsons]

Make sure the prop is sharpened and balanced well, that will help with torque roll a bit too. You could also shift your battery to the left to help fight it rolling right.

Today I converted the boat to a .098 flex drive and added an X427 prop.
Saturday will be my first opportunity to test it out. I'll post my results

Tried to make a run today but the wind was howling and made fit pretty choppy.
I'll try another day

A steerable outdrive with no u-joint?

A steerable outdrive with no u-joint?

Thats what i was just looking at.....

[G1ST]

It has a .098 flex shaft now. No U-Joint at either end.

Anyone got a part list to upgrade to Brushless ?
i got a stock mini-V and i wanna go Brushless ...
Shoul i upgrade or get aquacraft mini mono or Proboat impulse (small one) ?
Thanks for the help in advance =D

I'm anxiously awaiting the Minimono

Right now in my Mini V I am using a 3100kv 380 sized motor
.098 flex shaft to 1/8 stub shaft
1/8 to .098 motor coupler
X427 prop
All of the above can be purchased here at OSE.
35A Seaking ESC
11.1 volt 1000 mah lipo.
This set up is too much for the mini V hull but it's what I have. Very challenging to drive.
2 cell lipo or lower kv motor would make more sense.
IMO the hull is not really up to high speed brushless use. Too short and narrow. I've flipped it with just the throttle.
I think a hull about 18" would be ideal for the gear I have.
I will say I really have a lot of fun with my Mini V. Certainly not boring.
Hope this helps you

How much did it cost to build it?
Thanks

Including the boat (bought here in the swap shop) I'm in it about 125 minus batteries. I was lucky, mine was already set up and had a BL moter and a standard servo. I changed the ESC, added the water cooling and changed to flex drive and smaller prop. The brushless motor with the stock prop had wicked torque roll.

You can do it in stages,
1 Motor and ESC and add the water cooling. +/- 75.00 depending on motor.
2 Flex, coupler and prop. 30.00

Watch the swap shop for used stuff and you may save some dough.
Have fun

okay but,
Do the stock Tx,Rx can be used ?
Thanks =3

[G1ST]

Unfortunately no
The stock Rx is combined with the brushed ESC. Also the stock servo is 4 wire.

[679alex]

okay

Don't be discouraged
Half the fun for me is finding the stuff you need to assemble your project into something unique.
It just doesn't always happen instantly unless you are buying new.

i will try to use futaba Tx&Rx i found somewhere at 39$ ... Cant remember where but i will find it back or maybe the tactic from aquacraft and use your build :)
