Prop design priority list:
#1 Cruising speed
#2 Efficiency
#3 Response
#4 Durability
We worked very carefully on this prop with Gemfan in order to deliver a specific performance target. The goal of this prop is to have higher cruising speed with more efficiency without loosing too much response. The larger disk size of 5.21" also provides improved handling for todays 5" quads that are usually around or beyond 650g. The resulting prop its all the performance metrics and is called the "I Love You" prop because 521 loosely translates to I love you in Chinese languages.
The higher pitch 5236 version has higher top speed but less response and less efficiency.
What we recommend for optimal operation:
- ~2306-2507 or comparable motor weighing ~29-35g
- ~1700-100kv - 6S
- Max recommended quad weight for any 5" is about 780g AUW - lower is better
- Particularly good for 5" quads above 650g.
