INTRODUCTION

Firstly; A MASSIVE THANK YOU FOR YOUR SUPPORT AND PASSION!

We would like to thank you for purchasing our GP3D RC10GX ’89 IFMAR Worlds Replica
Conversion Kit. As you have purchased this kit it means you are passionate about the history of our
beloved R/C hobby and in particular one of the most iconic and revolutionary R/C cars we have
seen  the prototype from Team Associated and Masaaki that took Masami Hirosaka to the 1989
IFMAR 2WD World Championship at the famed St Ives track in Australia.

GP3D and our manufacturing partners are currently looking into reproducing some of the
additionally required ‘original’ components, such as; turnbuckles, hinge pins, motor plate/guard and
rear alloy top-deck stand-offs. Therefore, please keep following our FB page and website for those
and more future developments…

The 3D printed nylon gearbox and front bulkhead parts may have a thin ‘brim’ around one face
which you remove using a scalpel and then sand edges smooth as desired, do NOT tear it off.
Some parts, including the suspension arms are printed at ~45-degree angle to maximise layer
adhesion area and balance directional strength distributions, resulting in some edges not being
‘pretty’, but these and any parts can be trimmed and sanded as desired to clean up any rough
edges/extra material as you desire.

We hope you love and enjoy building and driving your RC10GX replica, we are always available to
help and support with any questions or issues you may have. We would also love to receive
pictures of your in-progress and finished model in your chosen style and liveries that we can add to
our online Customer Gallery!

Please contact us if needed: [e-mail] OR via my FB Messenger

Information and spare parts are available in our online shop: www.GrandPrix3D.store
Our replica build, including original spec electronics and tyres!

L&R
4-40 socket x3/8”
Only use 3x of your 4-40 x1”
bolts to mount gearbox to
your motor plate.
Tip: If needed, add 1/8” shims
under bolt heads if needed to
avoid bolt tip protruding past
motor plate into slipper.
