Rosco's 0705 Brushless Whoop

This is my first go at a brushless tiny whoop. Overall I'm pretty unhappy with the performance (see below). Check out the full review here:


  • Flight times on a fully charged battery, running until the motors won't spin (not good to do) is just under 2 minutes.
  • In any kind of self-leveling mode it drifts to the left. This makes flying in this mode really not very fun as you're constantly compensating.
  • It doesn't hover until about 75% throttle. This means you don't have a great range for throttle control.
  • In acro mode it's quite fun for about 1.5 minutes. It's quick, it handles well, and it's great for inside flying!

If I did it again

I'd definitely go with either:
A: Smaller lighter motors
B: A bigger frame that accepts bigger props.

I plan to swap out the battery connector so I can run bigger batteries to get better flight times. I hope the added weight of bigger batteries does't completely take away from the flight times of having the extra MAHs.

If you check out the information here on their "Brushless report" you can see why they recommend running a bigger prop on these motors.

Yea. The Sunnysky 0705s are Not really good. Also their 0703s heavly unterperform in comparison to the Racerstar or Boldclash. If you consider buying new ones I would recommend you the 0603 12000kv or higher

The Mark III supersedes the more budget oriented Wizard Killer Mark II and is the most featured packed, simple to build and powerful of the three. The base weight with props is about 326g and fully loaded with a battery..

At last, the Topsky F7X V2 is available. This is the updated V2 release which came 3 months after the failed V1 model from October, 2017. V1 had several issues and most reviewers declared it an utter failure. Did Topsky fix the issues and are these worth buying? Let's find out. On paper this sounded like a wonderful new goggle. Unfortunately we were let down. The displays exhibited ghosting, the..
