i'm almost 99% positive that as long as i'm not reaching the 180F, nothing would go wrong. i did many speed tests and 10-13 min running sessions with same motor/esc and lipo voltage and nothing went wrong even under some quiet hot temperature's here during the last summer. The only difference was the gearing as it was were 15/48 and now it's 18/44 .

btw, some guys with the same branded motor 2200kv ( mamba monster ) are doing some out of imagination speed tests under 6s lipo by using the gearing of 17-22/34 custom made spurs on a 10 scale 2WD trucks.

Just a quick heads up, the gearing you ran on your Vorza and what you have in the EB48 are quite different. The 15/48 is 3.2:1 and the 18/44 is 2.44:1. Then the Vorza's diff ratio is 4.3:1 whereas the EB48's is 4:1. The final drive on the Vorza is 13.76:1, which is close or slightly lower than a common 4s race setup. Then final drive on the EB48 with the way you have it is 9.78:1, that's a pretty tall ratio. Using this calculator I have ~52mph on the Vorza and ~74mph on the EB48. Even if those numbers aren't 100%, the difference between them is quite large. To achieve close to equal speed and performance between the two, you'd need a 13 tooth pinion on the EB48.
I'm not saying you can't run the 18 pinion with success, just want to make you are aware of the differences between your two setups.

Thanks for these great technical info. and yes, among your points stated above i'm sure that the vorza is clocked 52mph with that gearing and lipo voltage.

i tested it last night with half of a throttle, all good taking advantage of the cold weather at night.

if i understand you right, do you mean that if i used a 13 pinion gear on the eb48 it will equal the 15/48 on the vorza ?

Thanks again for the sharing such nice info.

smallest pinion I could fit with a tekin motor (similar dimension, maybe tab bigger) was a 15T and that was really pushing it.

Anyone happen to have a hot bodies big bore shock laying around that could take a couple minutes and see if the spring adjusters fit the threads and springs? tia.

In short. Yes, they will work. Top adjuster is Tekno ( I'm not screwing - pun intended - with my RH adjustment. Bottom adjuster is HB, though not purple.
First pic is with Tekno 410 F spring, second pic is with HB White F spring.

Sweet! Thanks for taking the time to do that...

I am considering the components that might be a good idea to order together with the car. So far I have come up with the following selection of components:

--- Complementary Parts ---

TKR4174 - M5 Pinion Gear (14t, MOD 1, 5mm bore, M5 set screw)
TKR4175 - M5 Pinion Gear (15t, MOD 1, 5mm bore, M5 set screw)
TKR4176 - M5 Pinion Gear (16t, MOD 1, 5mm bore, M5 set screw)

--- Replacement Parts ---

TKR5020 - Hinge Pins (inner, front/rear)
TKR5030 - Suspension Arms (rear, 2pcs)
TKR5034 - Hinge Pins (outer, rear)
TKR5036 - Suspension Arms (front, 2pcs)
TKR5040 - Rear Hubs (2pcs)
TKR5041 - Spindles (left and right)
TKR5042 - Spindle Carriers (left and right)
TKR5072 - Driveshafts (front/rear, hardened steel, 2pcs)
TKR5237 - Spur Gear (44t, composite)
TKR6004 - Shock Shafts (front, steel, 2pcs)
TKR6005 - Shock Rod Ends and Spring Perches (6.8mm, shock ends, 4pcs)
TKR6009 - Shock O-Ring and Bladder Set (for 2 shocks)
TKR6017 - Shock Shafts (rear, sterl, 2pcs)
TKR6023 - Shock Boot Set (2 front, 2 rear)

--- Option Parts ---

TKR5115 - Spur Gear (44T, hardened steel, lightened)
TKR6050 - Shock Pistons (CNC, conical, 10x1.1)

--- The End ---

I live in Sweden in Europe where we do not have any domestic retailer with spare parts in stock.

I will run the car on 4S to power a 2000 kV motor. I have been recommended by Daniel at Tekno RC to use a 15t pinion gear with that power and motor.

I would appreciate any input on the above selection of components. What might be a good idea to add to the lists? What might be a good idea to remove from them?

You do not need tekno pinions for this truck. If its cheaper for you locally source the pinions any mod 1 will do. Only spur is specific to car.

Also make sure you get front bumper at least (thats what breaks on these 4wd trucks a lot more than arms). Also get the aluminum hinge pin holders because the truck comes with 3 plastic ones and one FF aluminum. So for peace of mind get those and replace only if the plastics break (mine are new in pack still no breaks).

Also you might not need drive shafts, just replacing pins with a tool will freshen them up (since you run 4s the wear will be a bit higher). Shock shafts and all also might be overkill (they are already 4mm any thicker and it will be the size of a real 1/18 shock lolz). Also I never run boots in indoor clean tracks. If you are running in europe, I am guessing tracks are cleaner so boots are optional. Shock plastics are essential and so are the orings and all. Also get spare turnbuckle ends to replace worn out ones over a season or so.

Get the steering ackerman plate in metal if possible the composites known to break on buggy and they have revised it also.

Thanks!

I do not know of any indoor tracks for 1:8 scale RC cars in Sweden. And the outdoor tracks are more or less dirty most of the time due to the weather conditions in northern Europe, where Sweden is situated. So I think a Shock Boot Set can come in handy after all... :-)

Consider also some maintenance parts like, -diff o rings- diff shims- diff gaskets/seals and maybe some diff oils.
On the optional shock pistons I would get the 10X1.2

Also, if you run mostly outdoords I would drop the 14t pinion and add a 17t

This is the EB-48 thread not the SCT410

The EB-48 already comes with alum. hing pin holders

arms do break, especially when weather gets cold.
I've seen many bashers having arms breakage. and they've found "bubble" in the plastic as well.

i finished adjusting the camber links and went on testing it just few minutes ago. really happy with such buggy and it's setup. i recorded this short video to share it here with the tekno eb48 fans..

only half a throttle bursts i did. i just want to see how things go with it.

initial word : massive .
