Would you reccommend this type of setup to work well with the Caldera?
Its overkill to be honest. And that motor may require cutting some of the chassis for it to fit (might be larger diameter than a 540)
I know a 550 motor will not fit without modding the chassis, as that is what my buddy did to fit a 1/8 scale system in his. (the kid is a RC hack, LOL)
Id do this combo:
Redcat is coming out with a couple of new brushless models this march. Once they are out, I will know how much their systems will cost and the specs.
Even the system that comes in the epx pro's would be a decent upgrade, as its a 45 or 60amp ESC with a true 540 can motor.
The Twister's system is a 90amp ESC with a 540 can "sensorless" (smoother) motor that is 3930kv. That system I could get you for not much over $100 and should be plenty powerful for the caldera. I know some twister owners have run 65mph on a 3s. Thats double the speed you are getting with your caldera on 2s. The only thing is the motor has a 5mm shaft (not 3mm like the caldera's motor) so a aftermarket pinion gear with a 5mm hole would be needed. Robinson racing makes one that would work im sure.
There are plenty of options. Personally, Id stay away from anything meant for 1/8 scale or SC trucks (4 pole motor) as these will produce enough torque to ensure broken driveline parts. The SC brushless systems provide more torque at lower RPMs. Thats fine on 2wd or even 4wd trucks with narrow SC tires and a slipper clutches. Not so much on the caldera with fat tires and no slipper.
The systems I just mentioned will provide more speed without ripping the spur gear or diff gears to shreds every time you take it out.
remember, your ESC is rated at 35amp. and the motor is really a 380 size. So even the ezrun 60a combos with a 540 motor will be more powerful(epx pro system)....and could possibly either be geared up....or you could run a higher kv motor (stock motor is 3570kv) so something 3500-4300. You can raise the kv some because a 540 motor will have more torque to move the truck. A higher KV motor has a simillar effect as gearing up the truck. This can be done with a motor providing more torque.
The end result of a slightly higher KV, 540 motor and a ESC that can handle double the amps will be faster acceleration and more top speed. It will also handle 3s lipo without generating as much heat.
The twister's brushless system or the epx pro's brushless system would work. I can get either for about $110 shipped. With either system, you will need a differnt pinion gear. The epx pro system has a 3300kv motor, so a slightly larger pinion will be needed. The twister's system has a larger motor shaft, so a pinion the same size but with a 5mm hole would be needed.
I think I rambled a bit here, but the point being you want to upgrade the power system without overpowering the driveline.
The system you linked could possibly work if your program the ESC right and use a good throttle control. But it is meant for bigger models and could just result in a truck that spends more time on the shelf waiting for new parts[&o]
I may be interested in your deal thats not much over a $100 with an 5mm pinion gear. I don't want to tear the thing apart, but I do want power and speed if I can, so I can have fun with the fellas. Or the Twister's system you spoke about. I may want to try. Keep me informed on the way to go, but also on a budget.
