BOLTRC 2207L 1660kv (V3) MOTORBT071660
This motor has been specifically developed for 7in props on 4S. This is a performance oriented design with significant torque for heavy seven inch props. The higher KV gives you more top end with only minor impact on efficiency. We felt that flying 7in should be just as much fun as flying a 5in racer.
Although not officially part of the WORX series, the design is heavily based on the WORX motors but comes with a four hole (19x19mm) mount pattern.
The motor uses thick N52H magnets and 0.15mm stator lamination that delivers outstanding power and performance. Wound with thick 0.4mm single strand copper, these are not cheap motors, despite the price. The motors uses higher quality ABEC 5 bearings from EZO. These are the same bearings unique to our WORX brushless motors delivering a more robust and lower profile motor.
This combined with a light weight ~28.6grams (3cm wires) gives this motor an outstanding race pedigree. and most importantly, exceptional handling. Yes, you read right, 2207 with 4 hole mount at this weight!
The motor uses a 19mm mount pattern.
Whats the big deal with the weight?
Actually, weight on the end of the arms is more important than any other location on the quad. Our race pilots report noticeable improvements in handling. Any weight here is just magnified by the arm length squared, just google 'moment of inertia'.
How durable are these motors?
Durable enough for both training and race day. We make extensive use of advanced FEA simulation tools to design our motors to maximize strength and yet still reduce weight. That said, nothing in the world is for free.....ie. not to be used for proximity flying.
There are no big fan blades on the cap to keep the motor cool?
Light weight 'fan blades' are hidden under the bell cap together with large exit area at the base make these motors extremely well ventilated.
The wires supplied with this motor are extremely long, ideal for a 4in1 ERSC on a 7inch.
