702 is a size of motor that became popular in the spring of 2022. IIn my opinion, it's a unique size because it has extreme advantages and extreme drawbacks.
Semiplume Edition 702 motors are extremely low-kv motors. Most people would never consider a motor this slow. I decided to make this motor because I wanted an option that demands the same kind of throttle and weight control that original Tiny Whoop recipe demanded, similar to other spec quads, like DRL style 7-inch beasts, or Freedom Spec, or Tiny Trainer. These motors are for use only with very, very light builds.
Version 2 is the newest design of the 702 Onesie with shorter wires than ever! We still have some of the left over V1 motors with longer wires so were selling those too. The V1 motors came with 32mm wires and weigh 1.5364 grams. Nightwing did some testing with various boards on 65mm frames and came to the conclusion that we can shorten the wires to 23mm and drop the weight to 1.4538 grams. Saving almost a half gram in just wires alone! Please note that these shorter wires will not reach on builds bigger than 65mm. Please see picture below.
The truth is that for all speeds of 702 motors there is a 603 or 802 size motor that can achieve the same thrust with greater efficiency - but the magic of the 702 motor is the effect of dramatically reducing the weight that farthest from the CG of the aircraft.
When there is so much less weight to push around near the outside of the aircraft, motors do not need to work nearly as hard to change the attitude of the aircraft. It's hard to describe in words how this makes flight feel, but I love it. I can snap into any attitude as fast as I can think it, and I have the urge to just flit around the room, quick and agile. Part of it is ultralight flight in general, but the 702 reduction of outer-edge weight is the secret sauce of the 702 hype. This effect is greatly improved if you're able to get the dry weight of your aircraft real low, like below 18g.
For years the Tiny Whoop Onesie has been one of the most reliable, durable and efficient motor designs. We chose this design after testing motors made by manufacturers of all micro motor brands. This design completely solves the durability challenges of it's predecessor while remaining very lightweight. It's the reason that the 2023 Whooptopia survey showed it as the most trusted and most flown motor by a landslide, It's the reason we quickly replace any motor that breaks when it shouldn't.
The Tiny Whoop Onesie has always and will always tell the actual speed of the motor given by the manufacturer. Beware deflated numbers from other brands meant to make their version feel faster.
PCB Solder Pads
Like all Tiny Whoop Onesies, these babies now feature the PCB Solder pad upgrade, which allows for custom wiring colors and easy repairs. To access the PCB pads (where the wires connect to the motor) just peel back the black silicone. I'm proud to brag that our motors were not only the first Unibell motors, but also the first to feature these solderpads.
Tiny Whoop Pioneered the 802 Motor
802 size Motors are a big deal for 1s 65mm and 75mm Tiny Whoops. The wider, shorter form factor provides tons of prop authority, creating much more yaw control and control when you're pulling out of a dive, flip or roll. They weigh a fraction of a gram more than 603, but it's worth the extra control and power.
Tiny Whoop was the first to discover and release the 802 as a whoop motor.
