Since Ive only been 10 months into the FPV hobby, Ive some doubts about the behaviour of my second drone. -Once I armed the Cinewhoop its much noiser than my 5" Freestyle, is it normal that Cinewhoops are noisier? -When I pushed the throttle it takes around 40% of the stick to actually make it hover, when in my 5" Freestyle is around 20-30% of the stick. -It doesnt goes as fast as the 5" Freestyle. -Ive only flew it about 5-6 times, more than fly it to test it, and the motors get hot, its not hot hot, but comparing them with the 5" Freestyle that doest get hot all makes me doubt if they are the correct motors. Also, after each test, its comes a smell from the motors. https://ibb.co/prWFbty https://ibb.co/hmydvJr https://ibb.co/6sk6XWS   I would apprecciate any help ![[-]](https://intofpv.com/images/collapse.png) • Posts: 6,118 Threads: 172 Likes Received: 2,289 in 1,836 posts Likes Given: 4,737 Joined: Feb 2019 Reputation: 101 05-Apr-2021, 09:37 PM (This post was last modified: 05-Apr-2021, 09:41 PM by hugnosed_bat.) a cinewhoop is for slow cruising, to carry the weight of an hd cam and for touch something very gently without a freakout quad. the main difference is the guarded rotors and guarded rotors is pretty the whole benefit, everywhere else are big downsides from a "whoop" configuration.
about noise and hoover throttle value: a cinewhoop is pretty heavy compared to the rotorsize, it needs alot of rpms to provide the thrust to lift off. a lot of rpms does result in more heat (if they arent truly hot hot, its no issue) a lot rpms does give noise, ducts are known to increase the trust a littlebit and for increased noise.
nothing on a cinewhoop is made to go fast, dont expect any performance thisway. the deal is a stable platform for slow cruising, for a nice video.
did you cruise it or did you try to get topspeed, flips, loops... as a performance quad?
what can you smell from the motors? • Posts: 18 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 1 Joined: May 2020 Reputation: 0 (05-Apr-2021, 09:37 PM)hugnosed_bat Wrote: a cinewhoop is for slow cruising, to carry the weight of an hd cam and for touch something very gently without a freakout quad. the main difference is the guarded rotors and guarded rotors is pretty the whole benefit, everywhere else are big downsides from a "whoop" configuration.

what can you smell from the motors? I apprecciate the answer. Well, I think I did get topseed, but compare to my Freestyle doest feel the same. Flips or loops didnt tried, because since I felt it different from my Freestyle I dont know if it can handdle those moves. It can? Again, I dont know if its my paranoia, but the smell was if its going to "burn" hahaha. Then, its normal for Cinewhoops quads that motors get hotter than Freestyle quads? I havent fly it again, last time it was a weeks ago because Iam doing research if its a normal behaviour. Thnaks! • Posts: 18 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 1 Joined: May 2020 Reputation: 0 Extra info: When I did the build I had to put the ESC the other way so I had to do some CLI to get the correct order of motor plus, instead of re-solder another motors to get the correct spin I change it with the BLHeliSuite32.
Could all of this affcet the overall performance of the motors? • Posts: 6,118 Threads: 172 Likes Received: 2,289 in 1,836 posts Likes Given: 4,737 Joined: Feb 2019 Reputation: 101 06-Apr-2021, 12:25 AM (This post was last modified: 06-Apr-2021, 12:31 AM by hugnosed_bat.)

Could all of this affcet the overall performance of the motors? this wont be a source of the issue, if there is one. motors get hot from performance; rpms and rpm changes or from a bad tune. as the blades of your 5inch freestyler are longer, they need less rpm to generate trust. overall your freestyler might have a much lower avarage rpm during flight. you shouldnt try flips and flops :-) i wouldnt expect more than 50kph and good handling, the best speedlevel might be between 5kph and somthing like 35kph. what is the weight of your build with the gopro? whats the weight of your battery? 4s? what capacity? • Posts: 18 Threads: 2 Likes Received: 0 in 0 posts Likes Given: 1 Joined: May 2020 Reputation: 0 Ok haha, thanks for the "shouldnt try tip", Ill leave those for the Freestyle.
Mmm, not sure on the weight, but Iam running 4s batterys of 1500-1550 mha, Lumenier and Tattu. But let me check the total weight.
How do I know if my "tune" is right? • |
