BetaFPV - HX115 HD - A 3” Toothpick

Описание: This is a prototype version of BetaFPVs upcoming Humquad 115 HD. This is basically a toothpick on steroids with 3” props. It flys on 2S, 3S and 4s and also records 1080p video with the onboard Runcam Split 3 Nano. The FC is BetaFPVs own 2-4s AIO FC. For this video I have upressed the original footage to 4K for better viewing on YouTube. It’s flys very well and quiet on 2s, has a bit more power on 3s and is a beast on 4s. The flight footage from the video above is all from the same flight while running 4s. Initially I did not have jello but after a few crashes jello has started to appear due to dinged props. The props I am using are the HQ T3X3X3PC Tri-Blade. The Tri-Blade props have a lot of bit but I think they leave the quad feeling pretty floaty so I have since transitioned over to the HQ T3X2 BI-BLADE which I think provide a better flight feel and flight characteristics. I was having ongoing desync issues when using the 3-blade props despite my adjustments to the motor startup power, timing and demag compensation settings. All of the desync issues were gone when using the bi-blade props. Note that I am using a throttle curve for 4s and 3s with this quad because the throttle is very jumpy and not very linear at higher voltages.
