There are an absolute metric ton of 5" motors in this industry and they just keep coming out at a blistering pace. We've finally settled on ~2207, 2208, 2306 sizes with the 2306 size gaining a lot of traction in the past 18mo thanks to some really excellent props that have been engineered to manage the throttle curve of 2306 motors. With respect to performance, each motor size and prop combo has a unique envelope and each pilot chooses what they feel most comfortable with. For the most part low weight and high power for that low weight has been the goal. When moving into the purely cinematic category you will undoubtedly be carrying more weight on the quad so, low weight motors are always nice to have but power and efficiency tend to make more sense. For that reason, 2306.5 will be the motor size. The Kv will be around 1850 with the intention of 4S operation for supreme throttle control and sub 60mph speeds and 6S operation when you need to move quick. The larger motor is also more efficient overall given it's increased torque. While the weight is annoying and will impact performance, compared to the increased weight of the quad, it's not going to be a significant factor and the overall increased power window will be appreciated while not requiring a whole lot more amps. We're still running these things on 20x20 6S ESC's.
Racing is a bit of a different story. Overall, taller motors tend to be better at managing higher RPM's with more control....which makes sense when you think about racing and going fast. But then you actually look at a race and a lot of what they're doing is changing direction. They're not really maintaining high speeds for much of the race. There's no question that 23XX motors have more power at lower amps in the middle areas of the throttle and since a lot of racing has to do with efficiency and being able to finish the race, it just makes sense to us to use a 23 size motor over a 22 size motor. Also, the kv will be higher than typical 6S kv which is what racers prefer and the motor cost will be low enough for them to be bashed up and replaced.
We are absolutely NOT racers here at FPVCycle but we've definitely been around racing since it's inception and can't help but take part in the pedigree as it breeds life into all areas just like automotive racing so we're always paying attention. No doubt this motor will be enticing enough for people to consider racing with and we're definitely looking forward to hearing the feedback.
