3D-PRINTABLE EDF NACELLE FOR VQ MODELS HORNET SUBSONEX (+ OTHER ACCESSORIES)

thingiverse

I designed this nacelle for my VQ Models Hornet to eliminate the terrible pitching it has with throttle, which causes the plane's nose to drop sharply when throttle increases or decreases. This nacelle points the efflux up, effectively providing down thrust, which compensates for the high thrust line and makes the plane fly great. Here's a flight video with this nacelle and motor: https://youtu.be/2iATNxOVeFM It's designed to use this motor with a 4S battery: https://www.ebay.com/itm/JMT-70mm-3500KV-Brushless-Motor-for-RC-Airplane-6-Blades-EDF-Unit-Ducted-Fan/142493692168 The motor will draw 95 A with a 4S battery on full throttle, and it will cruise the plane fine on half throttle without overheating. I use a 4S 4000 mAh lipo. Use short pieces of 4 mm rod to join the EDF housing together, making sure the exhaust piece points upwards, off course. Print Fanhousing01 from ASA, ABS or PETG or other heat-resistant materials to prevent it from deforming from motor heat. The cooling fan part can be used on the end of the motor if it gets hot. The recommended motor usually doesn't get hot. Dynamically balance the impeller using aluminum tape on the blades by running up the motor with the impeller to low throttle settings and feeling for vibrations. Add tape and try again, repeating until you find the imbalance, until it spins without vibrations. The battery tray part is a raised part for mounting the battery with velcro straps in the nose. The Noseretractmount part is a spacer for mounting retracts in the nose. Safety warnings: - The EDF is a very highly loaded assembly at high speed, so it's essential that you know what you're doing. - Make sure the integrity of the printed impeller is good before trying to run it. - Always wear protective glasses when test running the fan. Always protect your eyes. - Do not run the fan at high power while holding in your hand. - Keep your hands and any loose items away from the fan when running, as it will shred your fingers if they get sucked in. If something gets sucked in, it can damage the impeller and potentially shatter, throwing loose debris out.
