This motor was designed for T-Type 3inch Propeller which is commonly used on 120-150 Quad Frame. It assembled with Imported NMB Bearing and Copper Wire to maintain the quality.

It assembled with Imported NMB Bearing and Copper Wire to maintain the quality. The motor has been balanced by Motion Balancing Machine so you will see the colored balancing mud in the motor. There are lots of brands who claimed their motors are balanced but in fact it is only static balanced (this means just to filter the highly imbalanced CNC out), its balancing quality is far away from real Dynamic Balancing. If you do not see the balancing mud inside almost all motors, that means their "balanced" word is just a joke. Be Smart & Buy Smart! Dynamic balancing is the most time consuming part when manufacturing a motor so factories don't like to balance the motors due to saving of labor work. RCX always cannot catch up the supply demand due to this reason (production quantity is limited by the balancing work). If a factory can supply heaps of motors to the market, do you think their motors are balanced well? If RCX does not need to balance the motor, the production would be much faster.

Advantages of H1105 over BE1104:

• H1105 has soldered with Soft AWG Cables which is much easier to solder
  
• H1105 has higher thrust and efficiency
• H1105 has been balanced by motion balancing machine
• H1105 is NOT heavier than 1104 motors currently in the market

Neat copper wire winding 
This H1105 motor made with Imported Copper Wire, NMB Bearings, Kawasaki Japan 0.2mm Silicon Steel. LOOK at the blue balancing mud, it is proven that the motor has been balanced by dynamic balancing machine.



Light Weight
H1105 V1 motor is weight about 5.5g. H1105 V2 is weight about 5.9g which 0.4g traded for more durability and easy shaft replacement.

Suitable ESC
You may use this XM-10A BLHeli ESC for this little high KV/RPM motor.




H1105 (V2) With Double Grub Screw
We took the suggestion from customer to add a grub screw on the motor so it is easier to change the shaft, and increased a bit of CNC on top of the motor for more durability for crash. These are the only differences between V1 and V2 Motors (you can mix both V1 and V2 motors on the same Quad). Click here to see the advantages and disadvantages of using grub screw on a motor.

If you place the order after 8th Jan 2016, you will be shipped with the H1105 V2.



Thrust Test Table
We have tested this 4000KV motor with T-Type 3020 Prop with both 2S & 3S. Both worked great.

** Notice: Motor is not exchangeable/refundable if the motor cables are cut (shorten) or motor has apparently damage. So if you want to test the motors to make sure the motors are working properly, we suggest you to use "Terminal Blocks" for connection between motor and ESC for testing. Thank you for your kind attention.
