4inch Racewhoop Pro

I decided to design my version of the amazing FreeZillion 3 inch Racewhoop, but in 4 inch.

Thanks to FreeZillion (https://www.thingiverse.com/thing:4608171) for inspiring this project.

I've attached the full project from Fusion 360 if you want to modify something. The TPU Addons are the same from the original FreeZillion project.

My choice is to use a XING 2203.5 of 3600Kv (4s) for this 4 inch version. The props are HQPROP 4" 6 blades ducted: https://a.aliexpress.com/_mPbmNqx

Here are the printing instructions to print out the Ducts from FreeZillion:
