JFtech 6-Blade 70mm Ducted Fan Unit Propeller Kit Set for RC Ducted Fan EDF Jet Airplane Aircraft

I bought this fan because I wanted more from my jet.i had a 64mm with a 50a esc , now it's a 70mm with a 70a e sc. I used a 4s 2200 battery and it was fine but soon as I put in a 6s 3000, the fan blades disintegrated.

So this is definitely a 3D scanned and upscaled product. The included propadaptor is too large in diameter even for a 1/10 buggy motor. However, the overall constriction is good, I was able to use a standard prop adaptor (and after much adjustment) to get it mounted and centered. performs quite well. In an EDF jet I've had for 2 years nearly 800KG total flying weight, and it clocked at 65mph!
