Libima 40 Pcs Plastic Propeller for STEM Activities Fold Resistant Propeller Blades with Rubber Band Hooks for Airplanes and Helicopters from Research Institution, 7.1 Inches(Red)

Worked in construction ar local summer camp. Kids from 6 to 12 built helicopters 3/16 dowel rods paper clip and rubberband....paper plate or foam wing and 85 turns. Worked perfectly. Was a hit

My students loved these for creating planes and cars in the classroom

KEEP IN MIND, the hole to insert attachments into the propeller is only 0.25 (1/4) inch/ 6 millimeters. Check your measurements before buying. I wasn't able to use them myself, but I'm sure they work for everyone else.

Parecen de buena calidad, loa peobare en aviones.

Excellent Product - Long lasting

These are very sturdy and well made.

Broke when planes landed, to be fair though it was for a HS class, not the gentlest of students

Does not fit 1/2" popsicle sticks. Have to order .25" sticks to fir the device.
