Custom 4 Link Trophy Truck Based on HPI Mini Trophy

[Jackington]

I have posted this up in the General Shortcourse section too, but seeing as this contains some parts from a Mini Trophy, I thought I would stick in here as well. Enjoy!

I found a HPI Mini Trophy on ebay a few months ago because I was getting the trophy truck itch and I had seen a few guys had done a fairly simple looking conversion on the Mini Trophy from the IRS to Solid Rear axle using an Axial SCX10 axle. I had an SCX10 so I thought, why not try it? 'How hard can it be?'

So I tore apart my beloved SCX10 and after an encounter with a dremel and a hacksaw, the mini trophy chassis was rendered in twain and I bodged the axle onto the back of the truck.

As time went on, I was a little disappointed with the performance of the mini trophy, mostly due to its super low chassis and the terrible job I did of cramming in the 4 link onto the chassis, so I decided to have another bash at it. This time taking inspiration from trucks like idealrc have built.

First job was to chop out all that I wouldn't need, which turned out to be everything apart from the from suspension assembly, which would leave me to build a whole chassis.

Cardboard test.



After I made the cardboard template I used some old Alu plate I had to make a metal mockup of the chassis to see how it would fit. Then I made a pair of upright panels to mount the rear suspension on.



The next task was to make the actual chassis, I called round to a friend of mine who supplied me with a sheet of stainless steel, about 1mm thick. Turns out cutting and shaping 1mm thick stainless with only hand tools is a tough job, but 3 jigsaw blades and some shrapnel injuries later I managed to make something worthwhile.







I am currently in the process of mounting up an SCX10 transmission between the two upright panels, its a tight squeeze! After that its just a case of finding somewhere to put the servo, and the finding some way of making that servo steer the wheels! Joy!

Thanks for looking! :D

Check the rotation of the diffs to make sure they both will turn in the intended direction.

be sure there is the same gearing in both diffs.

Time for a Christmas update!

I am finally back from uni for Christmas and can get back to playing with my toys, and boy do I have some toys to play with, the trophy has been waiting patiently for this week because of one special thing! NEW MEATS!

I decided there was only one thing that could make this truck beautiful, Vanquish wheels and RC4WD tyres. So I bit the bullet and shed the 150 or so quid from my wallet and splashed out.

But first, I finally got to painting and mounting the body. I decided to go with a blue on white scheme, and I am so happy with it.



Not a great photo, its shinier in real life, and I have a few more stickers to plaster on it.

Now for the tasty part, the first time I saw these Vanquish OMF wheels I was blown away by two things, how epic they look and how friggin expensive they are, but in the end, its only money. Plus there's so Many pieces! And everybody loves doing up 200 odd screws so what the hell!









Problem is now I don't wanna take it out and get those things dirty!
