The 7.5 is more than enough to have fun the few times at the track. You will need stiffer springs which are difficult to get for the old small bore shocks, if you are really interested in racing a set of mp9 shocks and springs and their upper shock mounts will fit right on and be the biggest upgrade you can fit. I'll put a setup sheet with the best settings for me, should be a good start for you.

Darn, and I just bought a set of front shock shafts as spares (I only had 1 new one left)! Oh well that's Ok. I'm only likely to every buy one new car, I'll always keep 1 of my 2 modded 7.5's. Lets talk chassis plates for a second, I have a fiorini which I bought off ebay a few years back for a decent price and has held up quite well and is currently installed on my nitro. I'm at a loss a loss with other OEM plates such as the original USsports and NEO - they bend and tweak constantly. Not like I ram into a lot of stuff, just the odd flip. The 7.5 just seems destined to bend chassis plates, and I can't justify $100+ plates all the time. 777 CNC plates are scarce now and very expensive. Is it just the 7.5 or are all platforms at risk of this.

Get the competition 7.5 chassis and shock towers instead of the 777 as they are different. I have two "pro" chassis plates well used and the RTR one, no comparison in strength. Should still be some on vendors. Later today I'll attach the sheet. The fioroni was good too!

Yes I pulled the trigger on that Fioroni years ago and got it for a steal at around $60 - now there are no more competition products left for this buggy but any oem chassis you find is $$$$. I searched for hours for a decent chassis ignoring pricing. Fioroni dumped the item, can't find any others at all when scouring the internet. This is really my fear about this car, everybody telling me it's a good buggy and not to upgrade unless I race - but I can't find parts anymore. NEO is the same but companies no longer care about RTR models so they've dropped compatible product lines. I looked up "competition rc" and found nothing. Is competition a name or were you just using it generically?

Yes generic term as the 7.5 is mostly know for RTR. I have a shop that say they have the race/competition chassis available, this. Can't seem to find my setup sheet, well the changes where mostly on the rear end.

Hi there, guess you never found that setup sheet then? Was still interested in doing some stuff before winter - but a broke a tooth on my spur and all 3 compatible parts are b/o.

Yep no luck finding it... So here goes the changes, rear camber link using the inside hole on the upright, -1 camber and top hole on the bottom of the upright. Front 2.1mm roll bar, B kick up parts (think it's stock...) and front holes on the steering rack.


If not mistaken the hyper 7 spur is compatible.

Thanks for the info, I shall investigate changing setup. Too hard to find parts for the 7.5, now I'm stuck (I've checked the Hyper7, different case hole locations) and a buggy is sidelined. There are other brands like redcat/hsp that are very compatible but like anything here in Canada there is nothing around - have to do expensive shipping from the states. There is a roller TKI4 kit that I can buy not too far from me for $250, I think I am going to go for it - giving up on the 7.5's I think. Too bad, recently bought $250 spares but I only bought collision concern ones rather than wear concern ones.

I have a torsen diff intended for a 7 that I think it fits, only put both diffs side by side for the moment...

About wear, the drivetrain is very good. This car has had at least 10 gallons through various engines and everything is still fine, the cardans are a bit sloppy and outdrives showing wear but otherwise very good car.

The tki4 is a better car but in my opinion too lightweight, front end could be stouter like the 7.5.

Hot bodies spurs should bolt up

Almost forgot that! Yep the d81x is closely related to the 7.5.

marcosphoto

HPI too I think.

marcosphoto

You guys could be right, the hotbodies HBS67428 HBSC1041 109841 appear to be similar. Problem is I can`t find these in Canada either :-(
