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 H1304 over BE1104/BE1105:

• H1304 has soldered with Soft AWG Cables which is much easier to solder
  
• H1304 has much higher thrust and efficiency
• H1304 has been balanced by motion balancing machine
• H1304 is just little heavier (about 1.5g) that 1104/1105 motors currently in the market but with much increase in thrust which 1104/1105 cannot give you.
• H1304 gains you more power without much weight penalty so it is good for who need to meet the restriction (eg. Flying Weight) set by their country. (eg. USA < 250g, Japan < 200g).
• CNC Material of H1304 is 7075 class which is stronger than most motors in the market.

Neat copper wire winding 
This H1304 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
1104/1105 motors in the market are weight about 6gt. H1304 is weight at about 7.5g which is only 1.5g heavier but it has much higher thrust and efficiency than 1104/1105. So it is really a good trade for the 1.5g weight.

Maintenance Parts
Bearing and main shaft are common consumable parts of a motor. You are recommended to replace a new one from time to time after a period of flight time.

• RCX07-435 Motor Shaft for H1304 Motor
• RCX07-293 Brushless Motor Bearing (Φ2*Φ5*2.5mm / NMB)
• Loctite 638 Retaining Compound - use it if the motor shaft is loosed from CNC or when you change motor shaft

Package Included

• 1 x RCX H1304 4000KV Multirotor Brushless Motor
  
• 1 x Screw Set
• Given as FACTORY AS IS condition. We do not supply different size of screws for individual customer. So please buy your desired length of screw for both bottom frame and top propeller because the thickness of the frame and propeller hub is not the same for everyone.
  

** 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.
