Nice! Looking forward to your updates.

Obviously something is wrong. It looks it might be broken or some connections inside the battery box are not (or wrongly) connected. I guess a call the the customer service will be the best option..

The old ones weigh about 13gram The new ones a little over 1gram less

Stud.io restored "a lost file". So i made a little scene of it. .

That smells fishy.... Please call customer services and ask for a new motor. Some of my motors have been running for years now and no problems at all!

Glad I could help! I did not remember it as an issue..

Did a picture/video review with my small MOD...

I think the rear too. Still don't like the yellow in this set...

@efferman Thats nice! Home printed parts?

Instructions for the alternate rotors are available at Rebrickable: Klick here

Thechnic-y... That was I aiming for.

I did already! The technic build rotors do not affect the speed. I may stress the PU-engine a little more.

As I am not a fan of the one-part rotorblades, I redid them in to an "axle-conector"version. As I did that for the 9396 already I kind of had an example, but they had to be slightly different. Of course I had to work with parts available in my spare-parts. Here is my version now. As I did not like the neon-yellow parts, I did replace those with white parts.

I never been much of a fan of the one-part rotors. So time to build them with parts. T here is another building mistake in the (printed)instruction
