Hi all !
Iīm a newbie to theese forums but I have had some experiense with lots of different cars during 15 years of this GREAT hobby !
I have introduced myself in the "Introductions" thread.
I just want to share my experiences with the above mentioned motors.
The Mini AC work REALLY well and itīs a direct bolt in, no modifications needed. The standard pinion will fit (2,3mm axle). The torque is really good and the "heat" build up is really low due to the built-in heatsink design of the motor and all the ventilation holes. It runs really cool and also cools down really fast after a run. The motor has external soldering posts for the wires wich is a really great feature I think. I have tested it on both 8 and 10 cells and it works very well on both. It also has a really great sound at around 50 000 rpms. This motor will be my first weapon of choise this summer.
The Mega 16/7/4 (4420 Kv) is a BEAST, incredible torque and REALLY cool operation. 6-pole design. 3,17 mm shaft. Throw ANY sized pinion and it will accelerate like CRAZY !
I started with 21T and ended up with 27T wich was even connected to the smaller "slipper" gear ! Awesome speed and even then incredible acceleration ! This motor also run even cooler then the Mini AC. Tempeture of the motor after a 10 cell GP1100 pack and monstergearing was between 50-55 celcius.
Due to itīs design with 6-poles most controllers cannot turn this motor at a high rpm. The U-Force 75 wich I used can "only" turn a 6-pole at 42000 rpms.
It goes like this; A 2-pole motor (Hacker, Lehner, Mamba for example) at 126 000 maximum, a 4-pole at half that, 63000 and a 6-pole at therefore 42000 rpms (divide 126 000 by 3), and a 14 pole at 18000 rpms.
I drove the car using both 8 and 10 cells. 10 cells is overkill (12*4420=53040 rpms) because the motor will reach maximum rpm with just 8 cells. If you hold the car up and punch the throttle you will not hear a differens between a 8 cell and a 10 cell pack. But because of the voltagedrop of the cells at this high gearing the car was abit faster with 10 cells.
Two great motors overall, but I like the Mini AC better still because of the usage of the standard pinions. The car with standard 48P Yokomo pinions doesnīt mesh up perfectly and therefore is noiser. But for speed the Mega is hard to beat. The Mega ranges from a 16/7/3 with 5580 kv to a 16/7/17 with 1040 kv.
