The Alienpowersystem sensored motor and ESC for the next (and probably last) power-upgrade finally arrived :)
Unfortunately, the motor is not a TP5840L (57x80mm, 836g, finned can) 1260KV as ordered, but a TP5670 (55x90mm, 962g, smooth can).
Bruno insisted that it's the motor I ordered and that it has 1260KV. Well, my calipers say 55x90mm, my scale says 962g and the Mamba Monster Torque Control KV-measuring says 1130KV. Now I have to re-think gearing again. But the good thing is, it seems to fit in my Slash, so atleast now I don't have that "maybe I should've gotten the bigger motor from the beginning" problem since it's already the biggest motor :)
Motor case is the new 2-Part case with only the endbell removable. The rotor is somehow scratched at the ends, I wonder if they throw all the produced rotors in a big box at the factory. Nice is, that it's balanced by drilling holes in the rotor, so no "balance putty" that might come off eventually over time.
The sensors fitted by Alienpowersystem seem to be glued into the motor with epoxy or something like that. Nice is, that they are "standard" Honeywell SS411A hall-sensors that can be bought everywhere for a few bucks.
ESC is an Alienpowersystem 8S 250A Gen3 sensored ESC. They seem to be based on Flier ESCs but with some changes.
Ordered the ESC "naked", without shrinkwrap, cables and heatsink because originally, the cables come out of the side which wouldn't fit in the Slash. But it came with heatsink mounted.
Interestingly, these ESCs seem to be made by hand, only the logicboard is probably pre-assembled because of the SMD parts on it. According to Bruno,
the ESC and Motor with sensors installed have been tested and "run nice and smooth". We'll see :)
From a mechanical and cooling point-of-view, the ESC seems good. The Logicboard is soldered to the larger PCB and not plugged with a connector like on Castle's XL2. Heatsink was properly mounted with thermal compound (the removable stuff, not glue). All cables connecting to the PCBs have been secured with silicone. Soldering pads for the motor and batterycables are quite large and on both sides of the PCB, 8AWG cables or even bigger ones fit without problems.
The FETs are some with a quite large case, not like the SMD ones found on Castle's controllers. According to Bruno, they are "Automotive-FETs" and are supposed to be more robust somehow. But it's only 18 FETs. Mamba Monster has 36, Mamba XL2 48. Well, we'll see.
Caps are 4x 35V 1200uF = 4800uF. For comparison, the XL2 has 2x 680uF and 2x 560uF = 2520uF. With CC Cap Pack (4x220uF) that would be a total of 3400uF.
Seems like the caps on the APS ESC are plenty, I guess I don't need additional ones then.
