Ultima SC/SCR Differences?

[Adam F]

Thinking about buying an Ultima SC as I can get one pretty cheap..

I have a complete ball diff from an RB5 SP2, set of RB5WC big bores and SP2 driveshafts spare already, what else is different on the SC-R?

Thats the important parts. The screws, ball bearings, main gear shaft, and slipper are also different.

Don't underestimate the importance of the screws, some of the mounting holes on my RTR Ultima DB/SC had stripped threads when I disassembled the car... The seltapping big threads are part of this, together with overtightening in the factory.

Perhaps I was just unlucky, as it wasn't the only problem: one the threads in the motor plate also turned out to be stripped as well when I disassembled the car for the first time. Luckily I won the car, as I am now sure I will NEVER EVER buy an RTR!

Anyhow, to get back on topic, I'd recommend getting an SC-R instead - RTRs are indeed cheap, but on every front money is saved: bearings, shocks (which are awful, they leak a lot and their construction makes it a pain to replace the o-rings), the stock tires wore down in 3 runs on the rear end of my car (ok, it was on tarmac but still it's pretty bad) while giving less grip than any other tire I ever ran with (on dirt, gravel and tarmac: the Proline Switch M2s make the car drive like it's on rails on all these surfaces and don't show signs of wear yet after 3 runs on the same tarmac) and I wouldn't be too surprised if the part trees that get rejected for kits are then checked if there are good parts on there for RTRs: The parts are ok, but I have the feeling all the replacement parts I bought so far for the car (which is an impressive list for the few runs it has had) are tougher Plus, using good parts from bad trees is actually a lot cheaper than using good, complete trees.

Negative as this all sounds though, I'm not trying to put you off getting an SC: I find the handling of the Ultima SC absolutely amazing! It's just a whole different car than the 2WD buggies I've driven so far, the over- and understeer comes and goes a lot smoother than on the 2WD buggies, which feel really nervous compared to these cars - plus, the SCs can handle way bumpier and rougher terrain
