Ford GPA Torro

[jarndice]

Andy thank you for not only telling us in detail about the problem but showing us how to fix it

Excellent info, but an N20! What were they thinking.
That is bad show.
I gave up on those with the original wpl crawlers as dual motors. I stripped the gears in less than a minute. Hence why i started making my own powerful dual motor setups.

I would be re designing that drive for more torque and could use some quieter units aswell.
Shame because to me, that drive motor ruins the model.

Maybe I need to buy one to design a new upgraded drive unit.
Thanks again for sharing.

@ Will, i hope it will last some time, when ist broken, i will look for alternatives
But i have to say, that N20 can move a lot, look here, also only 2 N20:

nice, those mines are very cool

Nothing against how great the model looks, it's a nice looking model and a great base for scale additions and paint to bring it to life.
I hear you on n20 motors they have good torque, my issue is that those gearboxes on the n20 motors are soo weak, they wear quickly and therefore it will not last.
I might have to buy one in the new year or borrow one and develop a lightweight but more powerful motor drive system which will also be quieter.

Where does your trailer come from please?

This maybe?

The Sol trailer is wrong with its wheel being far too off centered to the rear.
The one in the videos is much more accurate hence my wondering.

Hi,

@ Willi, i will look for it
And i keep you updatet when its broken, ore broken by a friend, some more GPA´s are in use here.

@ Manu, the trailer is made scratch by a friend, he made in the past some more US trailers. They also have working spring system:

first is 1;18 scale (for a willy´s 4x4 RC 1:18), second and third is 1:16 scale.

@ Jee, that are the mines, the kit is from Fertigungswerk16.at, look build that way:
