Tamiya Rising Fighter / Grasshopper 2 4 Bar Front

Sick of the terrible bump steer and poor handling at the front of your Tamiya Rising Fighter, Grasshopper 2 or Super Hornet? This is for you then! This item is the key to converting these classic buggies to a 4 bar front suspension.
This is also part of my Ultra Hornet DF01 tranmission conversion to make an awesome, fully independent suspension Grasshopper2, Super Hornet or Rising Fighter

Preparation:
Pull the original steering arms, wishbones, uprights and wishbone cover off the buggy. I would suggest drilling out the holes in the conversion piece using a 3.1mm drill to give good movement. Replace the wishbone cover with this item.
Remove the servo, and replace the 2 small ball studs on the servo saver with 2 x 5mm ball end (see parts list below). 

For the conversion you will need:

Suspension and steering:
2 x Tamiya 10004254 DT02/3 D parts (for the front wishbones and servo mounts)
2 x Tamiya 10004252 DT02/3 B Parts (for the front C-hubs)
2 x Tamiya 10555059 front uprights 
2 x Long Tamiya Screwpins or 3mm x 48.5mm suspension shafts
6 x Short Tamiya Screwpins or 3mm x 22mm suspension shafts

Upper arms and steering rods:
Either DT02 turnbuckle set 53828 with just 2 out of the 50592 ball connector set plus 4 x 3x12 self tapping screws or:

Tamiya 50592 5mm Ball End (this is 10pc, but you only need 4)
Tamiya 19804206 5mm Ball Nut (4pc, you only need 2)
Tamiya 50875 5mm Ball Connector (8pc you will need them all)
M3 threaded rod
2 x M3 x 16 machine screws
4 x 3x12 self tapping screws

For the Grasshopper2 and Super Hornet you will also need Spring Mount Tamiya 9805082 and some front shock either Tamiya CVA mini shocks (64mm long) or similar length oil filled shocks and mounting hardware.

Install the Wishbones 'wrong way around' with the flat sections nearest the bumper and the angled side facing rearwards. Use the long screwpins or 48.5mm shafts to mount to the conversion piece. 

Install the C-hubs and uprights using 4 of the short screwpins or the 22mm shafts. 

Cut the servo saver mounts from the wishbone sprues. You need 2. Screw a 50592 ball end into the end of each of the servo savers. Butt the servo saver up again the chassis in front of the front shock arm rib in line with the top of the chassis. Use the hole in the servo saver as a guide to drill a 2.5mm hole through the tub. Screw the servo saver to the tub using one of the 3x12 self tappers. Drill a second 2.5mm hole through the servo and the tub in front of the first screw and screw in the second screw to secure. You now have you top arm mounting. 

Slide the bottom of the shock into the outermost shock mounting hole on the wishbones and use the final two short screwpins to secure the bottom of the shocks. 

Install the ball screws on the front of the c-hub tops using the machine screws. Now make up the top arms and new steering arms using either the turnbuckles or cutting the threaded rod and installing the ball connectors to the ends. I can't advise on exact lengths as it depends on which connectors you buy. Install the top arms between the tub mounts made from the servo saver and the c-hubs. Install your steering arms to the servo saver and re-install the servo and connect them to the uprights.

Setup the suspension so the front wheels are a degree or 2 of negative camber and a little bit of toe out. 

Re-install the wheels and bodyshell and you have 4-bar front suspension.

There is a build thread on this over on Tamiyaclub forum. Search "Rising Fighter 4 bar" and you'll find it.
