QSL 85mm Ducts were designed by Andy Shen and utilize the QSL ShenProp 85mm x 6 Propellor to convert just about any drone frame that supports 4” props.  

Why 85mm?  

Because the Shendrones Geyser has always been at the top of the performance envelope when it comes to Cinewhoops but suffered from a critical flaw… Hand cut props are now a thing of the past when it comes to having the most versatile and best performing GoPro class Cinewhoop.  

These ducts will fit on the current Geyser platform, however we highly recommend converting to the new Terraplane frame that Andy has developed around these ducts. 

Injection molded by HQ Prop these ducts are not only durable but also feature 2 screw mounting that affords users the quick and easy install and removal without removing motors. With 16mm x 16mm mounting you can use a wide variety of motors but we suggest 2207 2500kv for most applications. 

With these ducts users will require new hardware (NOT INCLUDED) to mount your motors and we suggest 3mm of thread for most motor bases.  To calculate this users will need to take the carbon thickness of the frame and add 3mm for the duct base then add 3mm for the suggested thread length into the base. (i.e. 3mm carbon thickness means 9mm screw length).  Using washers between the screw head and the carbon is suggested if you cannot find correct length screws.

  • Diameter (Outermost)- 102mm 
  • Height- 39g
