"Alternative" 1/18 bl motors?

[lincpimp]

Heres my take on mini motors. I have had a mini-t, mlst, mini quake, vendetta, rc18t, rc18mt, rc18r. All were run brushless and I have sold all except the mini quake, my favorite.

The mamba/tekin motors run hot, so do the feigao s and l can 120 size (s can same as a mamba).

The golden horizons 3600 and 4700 motors are the s**t for the quake and vendetta. The 3600 is a 3s motor the 4700, 2s. Only drawdack is they both have 2.3mm shafts. Since they are finned they run cool. I currently run the 4700 in a 13" gecko boat and it does 28mph on 2s!

Feigao 280l motors run great in the quake, yet again a 2.3mm shaft. This is a big motor and most likely can pull more than the mamba 25 can handle, although I have abused my mamba 25s and they have never died on me! I use a 3500kv and run 3s. The quake likes to take off at around 40mph, which is about 2/3rd throttle! The quake needs more torque to move than a rc18 cause of higher diff gearing and weight, thats why I wnt to the 280l.

I have tried a hyperion motor, 5000kv 22 series xl in a vendetta and it ran hot on 3s, but the body was on and had no air cooling. Inside the vendetta is very tight with the std steering servo and a 3s 1800 lipo. It had tons of power, full speed wheelies, etc. I have heard that the l can hyperion 22 series are nice in a rc18. BPP sells them and they are reasonable cost.

GWS l can motors suck, even in a mini t, so I doubt they would be any good in a rc18.

The hacker 13 was a good 3s motor, around 4200kv IIRC. Would go hacker over the mamba.

I would recommend trying the GH 3600 or 4700, not sure about the fit in a 18t, but the chassis cutout should give enough claerance fir the fins. You said that you found pinions to fit the 2.3mm shaft?

Heres a link to the GH motors:

I too love my miniquake SE, its so tough i can't believe it. I have a setup in mine thats about 3/4 HP electric (3s) and it has so much more torque than it needs. The only problem is the battery size, it used a shotgun type battery without the caps on and thats all, makes it hard to find good LIPO's.

I also ran the 4700 GH motor and loved it, I just wanted to break new ground and be the first to run a Neu in mine. I have a Neu 1107/2y (3500kv i think), its an awsome motor. It does not like the mamba 25 though, coggs very badly at times, I do have a quark 33 to put in sometime

Edit; I forgot to add on the Lehner motor (1020), its a 1/8 shaft

I've been running DualSky lipos in one of my MQs or Vendetta for a couple of yrs- they fit like they were made for the MQ or Vendetta batt compartment. They had one rated at 1700 and then things started to change. The next was called xpower was same size but only rated for 1500. They did go from 15C to 20C though. Now looking they've changed again, its now 1300mah but rated at 25C in the same size.

The 1700 never delivered that much, mine were always running 1400+ so the 1700 was prob optimistic. The 1500 was pretty much the same so I'm at a loss to understand the 1300 de-rating. I don't know if these qualify as "good" lipos, but they've worked for me. Apogee was supposed to come out with a "small form factor" lipo, but I don't think they ever did?

I was out of town for almost 90days earlier this year and all my lipos puffed at least one cell, so I've been slowly replacing them. I guess I'll try the 1300 and see what they'll do.
