702 28KKV Delta Concept - Project Topspin Tiny Whoop Motors

The Delta Concept Motors are another small batch motor we're testing based on requests from the community and inspired by the never-ending debate about brushless motor winding styles. They are magnet wire motors, part of our plug-less ultralight series of brushless motors. 

There is a LOT of discussion about these two winding styles (WYE and DELTA) when it comes to micro motors that are as small as a 702, which is among the smallest brushless motors on the planet. Most micro motors are Wye winding, but some pilots noticed that there are now a few brands quietly offering delta-wound brushless motors, like rcinpower, t-motor and nbd.

After a lot of research I've decided I'm not drawing any conclusions, but I'm curious if Delta termination could have some benefits - namely a stronger initial pop of power (due to a lower winding resistance) with an overall lower likelihood of timing errors or jitter. After testing myself I decided it was time to ask the community. 

Delta Concept motors weigh an average of 1.23515g each

INTRODUCING the LIGHTEST 702 Motor on earth, with Improved Efficiency, Higher Maximum Thrust, and Faster Response and an un-slippable LOCKING SHAFT. 

Tiny Whoop Project Topspin motors mark a turning point in the innovation of the Tiny Whoop recipe. Here are the highlights:

• Extremely lightweight: 1.22g, 1.38 with wires and plug
• Slightly Faster Response, Higher Max Thrust
  
• An un-slippable Locking Shaft
• Available in 702 and 802 in tons of speeds, with 1.0 or 1.5mm locking shafts.

ULTRALIGHTWEIGHT

Reducing the weight farthest from the CG (center of gravity) also makes changes to the aircraft's attitude easier, leading to less finicky PID tunes and less thrust necessary to quickly adjust your aircrafts position or orientation.

Smooth, Powerful, Responsive.

Due to a lighter bell swinging less rotational mass, Project Topspin motors reach a slightly higher maximum thrust, and can achieve this higher thrust more quickly. Faster transient response is what gives your aircraft the responsive POP you need to make a lightning correction, snap into a turn, save a dive or scream off the launchpad. 

You'll feel it. 

YES, THAT'S A LOCKING SHAFT

One of Project Topspin's most significant advancement is the world's first un-slippable LOCKING SHAFT. The key and keyhole mechanism means that slipped shafts are a thing of the past. My god I can't tell you how good it feels to say that. 
This innovation took years of attempts, and even after a manufacturable mechanism was developed lots of delays and challenges arose. The final result is this perfectly balanced ultralight shaft that fits into the motor bell like a key in a lock.

Simple, elegant and highly functional.

EPIC VARIATION

When you're in flight your aircraft is an extension of yourself. It deserves an upgrade that is catered exactly to your flight style and the way you have fun enjoying the gift of flight.

That's why we've got by far the world's largest selection of motor speeds for both 802 and 702 sizes. Each has its place in Tiny Whoop culture, with a purposeful balance between power, weight, flight time, response and resolution.
