i could listen and watch this for ages , what a sound and model, thanks for sharing this 👍

That sounds amazing. A whistling sound would be cool too.

Very smooth flight, and a great looking model

nice bird Jesse

Sounds amazing yet seems under propped. Needs more pitch. Cool looking model!

Hahahaha that's badass!!! 🤟🤟🤟 Sounds like a race car flying by!! 😂

While the model looks okay in the air, it appears it is operating at 55 % throttle. Some concern was expressed about overheating at the start of the video regarding this. Is this why the model seemed a bit sluggish?

What prop size did you used? Looks like need more pitch
