5" Injected UDP Propeller Guard 4-Pack

Designed for use with 4" props on most 5" frames. We recommend HQ Duct 4x4x6 props. (PLEASE NOTE: DO NOT USE WET THREAD LOCKER WITH INJECTED UDP-GUARDS AT ALL, IT IS NOT NEEDED - IT HAS BEEN FOUND TO EAT RIGHT THRU THE HQ PROP DURABLE MATERIAL! IF USING, PLEASE LET DRY ON SCREWS FIRST) Made of durable HQprop material. Features Increased Safety Increased Efficiency Quieter Flight Noise Smoother Flight Performance Acro-able Aesthetic AND Functional Drone Accessory Customizable UNIVERSAL FIT Compatibility Frame: 5" or larger Motors: any motor using a standard 16mm-19mm four bolt pattern like 2206, 2306, 2207, 2604 Recommended Propeller: 4" Gemfan 4052 Easily convert your current 5" or larger drone into a safer smoothed-out cinematic flyer! Outdoors and now also INDOORS, HD cam or just fun flying! They fit any 16mm-19mm (4) screw bolt pattern and are optionally shipped with multiple sizes of rubber spacers that go under the arm between the arm and UDP-Guard to lock in the perfect height while also dampening the whole system and keeping tension on the bolts to keep them tight. 99% of frames that hold a 5" prop will fit these STAN FPV UNIVERSAL DUCTED PROPELLER GUARDS! You can simply bolt them straight onto the bottom of each arm with your own longer bolts from the hardware store / garage, or pick up the 5" UDPG add-on kit with your guards that has everything to get you going! (including Longer Bolts in m3x8mm and m3x10mm/TPU Spacers (4) 1mm and (4) 2mm / Removable TPU Tops available in 13 colors / Set of Recommended Props). You can use the rubber spacers between the arm and guard to dial in the perfect height and/or add clearance. When tightened, the bolts are then recessed in the guard to give you BUILT-IN non-metal landing skids so you can effortlessly slide along concrete or anything your heart desires (soo useful and FUN!) This set-up uses a 4" propeller in place of the bigger one and outperforms for cinematic flight in almost every way! It lets the motors work less with the same performance which enables our propellers to handle a higher load and give better flight times because of the increased thrust and efficiency! They more than make up for the weight of themselves while providing safety and smoother flight feel. With my highly tuned ducts, the smaller higher pitch prop performs like a smoothed out version of the larger ones giving you higher CONTROL, MANEUVERABILITY, SMOOTHNESS and SAFETY in the place of TOP SPEED - They can easily be installed or taken off to give you two flight styles on the same drone.. on the same tune.. Two drones in one! 🔥🔥 These guards were years in the making. Stan, the designer behind them literally put thousands of hours into the development of this awesome product. This NEW INJECTED VERSION is manufactured by HQ Prop and they are made from the very durable polycarbonate that they use for their amazing props. These guards are now NEARLY INDESTRUCTIBLE. If you fly 5" drones, then you need at least one set of these to share between all your 5" quads or a set for each build! They are for when you want the unique feel they provide and /or want to get close to people and property and get those EPIC cinematic shots much more safe and controlled! Either way they are now an invaluable tool in the arsenal of mine and many many drone professionals around the world! Includes 4x 5" Injected UDP-Guards (PLEASE NOTE: DO NOT USE WET THREAD LOCKER WITH INJECTED UDP-GUARDS AT ALL, IT IS NOT NEEDED - IT HAS BEEN FOUND TO EAT RIGHT THRU THE HQ PROP DURABLE MATERIAL! IF USING, PLEASE LET DRY ON SCREWS FIRST) *Longer motor bolts necessary (2mm-4mm longer depending on your rubber spacer configuration and frame thickness. Likely to be 4mm increase in bolt length with 2mm spacer or 2mm increase with no spacer) *Fly responsibly and within your skill level. *Don't risk other's safety in any way. *A heavy quad can break things when it crashes even if it doesn't break a nail doing it.. SO ALWAYS BE CAREFUL EVERY FLIGHT!
