I just got another Asuga!
It's a complete RTR. They sold it for the price of a roller.
The guy at the hobby shop said it was used once by Corally themselves for one of their videos.
A few scratches on the front shock covers and chassis, and some dust, is all i could find.
I couldn't pass on this opportunity.

What do you guys say?
Keep it stock, or make another beach monster out of it, like the other one?

What motor should i get for running on 4s?
The 4985 is such an amp hog that it cooks 4s batteries.
A 4282?
Is that noticeably stronger than the stock motor?

Edit.
I am stupid. I have Castle Creations 1520 motor to try. Totally forgot it's in my Muraco now.

I run a max6 4985 combo in my FTX DR8 (exclusively, although I tried it on 6s once or twice) on 4s without any problems. It is a heavy motor combo though.
A 4282 has a bit more power, around 15% compared to a 4274. A 4985 has 5700W, which is a lot more, but also quite a bit heavier.
I’m going to try a 4292 in my Muraco this season, could be a good motor, but a 4985 isn’t that much heavier.

Update.
I did some short 4s test runs right out of the box. I was pleasantly surprised with the car's performance. Mind you, i already have a roller, which i immediately equipped with a bigger motor. I never tried the stock Kuron 825. The handling is acceptable but very stiff, however, the traction is crappy.
The front diff appears to be almost empty and center and rear are better, but obviously have light fluids.
I took the front apart yesterday and put 500k cst oil in there. The center will get 1mln, the rear 250k.
I almost regretted running the car straight away. The amount of hardly tightened screws was shocking. But if this car was indeed ran by Corally once, i can't blame quality control here.
The claim that Corally used the car once, i am inclined to believe.
The vent holes in the rims were already taped, front droop was greatly reduced and the adjustment rings for all springs were tightened a lot.

TC’s stock combo is fast, but runs hot especially when temperatures will go up.
Edit: the stock motor is a bit small for a 1/7 car IMO.

I experienced that when i first got into the bigger scale cars with my Mojave. I burned that motor in a week. Even the 1520 motor struggled with it. I burned one of those in no time also. Performance on 6s is nice, but is rather disappointing on 4s.That's how i ended up with the 4985 motors.
That's also why i got the roller when i bought the Asuga last year. The 4985 motor in the Asuga is capable of propelling it to 60 mph on 4s. I like to stick to 4s for the weight and size of the batteries.

So, i worked on the Asuga last week.
I filled the diffs, put Mojave shocks and springs on this one as well.
Now i need to modify the TC shock caps to fit the Arrma shocks.
The HW Max6 system is in.
The ESC fits perfectly. There's just enough room to screw it in the original ESC position. It's almost like TC anticipated people would do this.

That makes me wonder.
Corally, why on earth didn't you leave room for bigger motors? Why do we have to cut into brand new Asugas, to accommodate larger motors?
You should offer longer side walls.

When i ordered the Max6 system with a German HS, i ordered some small parts from a famous Dutch HS, at the same time. Both came in within 4 business days. The Dutch order however, had parts on backorder AGAIN 😡.
When will those guys ever learn?
GET YOUR STOCK INFO IN ORDER, ffs!!!
That never happens when i order from German sites. You should be able to deliver next day!
End of rant.

Anyway. We now have 2 Asugas to run.
They are both red. That'll be confusing! 🤔😦

You can modify shock caps to fit or you can just use arrma standoffs & arrma shock caps, scorched rc titanium ones quite nice copied Horatio getting these. But I have arrma shock caps on front & corally at the rear my arrma shocks only came with 1 set shock caps.

Your Asuga looks neet. Upgraded hinge pin holders, metal bulkheads, 7075 and carbon parts and all.
I did the metal bulkheads on my Arrmas, because i kept destroying diff gears.
I think it is caused by the amount of flex in the chassis. I may upgrade the chassis plates.
I don't have that problem with the TC's. They are fine as is. I did bend the front tower on the Muraco. The stock one is thin as paper. So i replaced that one with the TC 7075 tower.
I may order another set of the ADU braces and another TC metal diff mount, to put in this one. It looks like that's all i need to make it (my) bash proof.
I usually only do upgrades amd mods when parts fail, or when i expect them to fail.
About the shock protectors. I like the TC ones better. The TC stand offs are fine with the 4mm bolt through the tower.
I broke an Arrma stand off and replaced two of them with TC. I drilled out the 3mm hole to fit them.

I may just have to gear down a bit?

A 1650kv motor has about 20% less rpm than a 2050 on the same voltage. Since an Asuga has a 13T pinion stock you’d need about a 16T to get to stock speed. I’d probably go for a 18T or 19T on 4s though, since stock speed on 4s on the asuga isn’t great (55 km/h) and I expect you want a bit more than that😉.
On my DR8 I usually run in the 16T - 18T range (on 4s) depending on outside temperatures, which pinions I have on hand and which tires I will be running.
I’ve found the 4985 stock motor bearings aren’t that great and become gritty pretty soon when running on dune sand. So you may want to start looking for spare (and better) ones. According to the HW site the motor bearings are high quality made in Japan, but when you open the motor they say Singapore or Taiwan (can’t remember which one).😄
 
I have been running 23/46t with the 4985 motor in the first Asuga. According to a gear calculator, it does 100 km/h on 4s and 150 km/h on 6s!
I get the feeling that calculator is a bit optimistic, though. I don't have a GPS to verify.

It was a bit too much for the 4s batteries in grass only. No problems on other surfaces and 6s, but i am reducing it a bit anyway. I'll take 95 km/h om 4s, and the occasional lunacy on 6s.
As for the bearings:
I just use the stockers till they show too much play. My other 4985 motors have SKF bearings with a tighter tolerance than usual, already.

23/46😳… if you have a nice flat open space than why not.👍
I ran 22/46 with way too big tires for fun once, on the stock 150a quicrun with 4082 motor and after a couple of minutes of cogging my 4s lipo was dead. Or maybe the 4s lipo was faulty I don’t know.

That was the tallest gearing i could fit in the stock motor mount. I was curious how that 4985 would do. I only had problems on grass.
Initially it ran hot with the stock body.
Even with 2 40mm fans on 7.4 volts.
Then i realised that at the speeds it can reach, it would probably stay much cooler with some natural air flow. So i cut out the windscreen, the fake side vents and i cut vents on both sides over the motor and esc. It stays cool when driving at speed. It doesn't like wet grass.
