http://i.imgur.com/L2ViWpwl.jpg New wheels and tires. Shocks adjusted. New ball ends on order. IIRC I had previously moved the shocks way down to increase the ride height because the back end would slap the ground with the lower profile street tires I had put on. That's also why I removed the wing ...

Welcome to the forum, nice cars! I like that Turbo Raider, actually. :) You're in good hands here but yes, there's a bit of a "re-learning curve" when it comes to modern electronics. It's not possible to make a single post to answer all your questions and teach you everything you need to k...

It's done! 15T Brushed / 2S LiPo / ESC / Low Voltage Alarm http://i.imgur.com/D9pXMwfl.jpg This thing is crazy fast!!! Good thing I ordered that extra set of ball ends. 3 old ones cracked open when I rolled it. http://i.imgur.com/8yhwyPjl.jpg Questions... How do I lower the center of gravity? The sh...

This was an awesome post to find! I just resurected an Ultima II that was given to me. I'm deciding if I'll convert it to brushless. Right now its got a trinity monster motor, a hobbywing 1060 esc, running futaba radio and servo. I'll snap some pics of it later to add here. As well as another link t...

Poor quality Nitro Brute video. Look how cool it looks with the big tires before Derek ruined it!

Hey all. I thought to dedicate an own topic for this car. I started to model some parts to my ST GP some time ago and the things just went out of control when i win a bid on BNIB Ultima ST Type-R EP. Before assembling it, i recreated all the Type-R specific parts to my PC, so i could easily print sp...

I had an Optima right when itgot rere'd in 16' and i raced it outdoors and on carpet, alot of running and i never wore any out. I sold it few yrs ago☹ so i cant look at it. But I do have two 80's Turbo Optimas i bought used and restored, neither had worn pins

In your vid, it looks like the right side has alot of play in the axle thru the bearing. Check that...does the truck have full bearings? it needs to. On the left side (and probably right side too) alot of play is coming from the rod ends. Mine had that to...if u look 2 pics up, i installed rod ends ...

question from Nitro Brute thread: The trannys are quite a bit different on my Nitro Brute vs your Big Brute. Yours just has a pinion gear/counter gear/differential gear. Mine has the input shaft coming in the back with a ring/pinion setup changing the direction of the gearing....big difference. I do...

I have an old CAD file for a plate that goes between the motor and gearbox. I'm wondering if it was designed to fix this particular problem. I can't remember the details but 15+ years ago I bought some prototype parts off a guy who also included the file for me to have them manufactured. I never did...

You would think so...the Optima & Ultima originally had the same dogbones...62.5mm pin-to-pin. I don't have any re-re's so I can't confirm with those parts, but I imagine they'd be the same?

Just measured a rere Ultima and Optima....getting 62.5mm pin to pin on both

I used to have a usa-1 and had the same issue. It was really frustrating. What I ended up doing was to get metal tubes and used them as a support tubes for the motor mount screws inside the tranny case. I JB welded the tubes to one side. It took away the flex in the case I wish I could remember the ...

Marwan RC has the tires for your original rims that are like the original tires....the guy at the hobby shop needs to know his business
