Hi

I just bought this 1:35 boat, and im looking for a way to power it.

I thought of using 2 broken digital servos for power.
If you glue the potentiometer in the center position, you can make the motors run each directien indefinatly, according to stick input.
This makes the "servo" a ESC itself.

I could buy a V-mixer you use on flying wings for my 2ch radio.
Then i can use differential thrust to turn the boat.

Or I could just use a Y harness, and install a working rudder....or 2

Only downside on usung a servo motor for power is that the resulotion is not very good. From zero to 50% stick movement, it goes from 0-100% motor speed smoothly . The last 50% stick movement does not make the motors spin faster.


What do you think of this ?

I prefer the operational rudder vs differential steering.[8D]

My Feedback: (3)

that looks cool, and sounds like it will work. Is that a different motor than the servo came with? And are they running on the same channel?
If so, It might be weak.
Love to see a vid of it working!

Good job.

I have one of those kits stashed away.I always had the idea of using it as a reference for a 1/6 model with GI joe type soldiers and stuff[8D].I am interested in this thread because your ideas seem practical and more likely given my motivation.Keep it up!

Thanks guys.
Those are the servo motors.
I have been asembling it, and it seems to be quite heavy when all the bits go onto it.

I dont think it can support the weight of the items above when finished, but we will see

Hi SJN! (i´m new here and from germany, not french gujana as my profile says)

I would rather try a single speed 300 on this boat (check in a washing basin if the weight is ok) with sanyo 500 nah nicads and a fully- submerged prop.
I used this setup for a DGZRS Arkona from revell, which is a bit longer than the pibber but more narrow, so the displacement schould be similar.
The results were amazing, the boat came easily on plane, although it was lying a little deeper in the water than scale when not driving.
As the pibber is very broad and thus has much planing surface, it schould easily handle some extra weight.

I see some problems with your idea with the servo engines, which are:

- not enough power. I saw some harbour tugs powered with two servo engines, but a pibber is supposed to come on plane and be FAST.

- what are you gonna use for props, driveshaft etc.?
as far as i know there are no useful ready parts in this size available.
such small props as would be required for fhe servo motors would be awfully inefficient

so if weight allows, i would really prefer the single speed 300 setup for reasons of power output, efficiency and because you can build the complete drive from premanufactured parts

Anyway, good luck and please keep us informed!
