EDF RC Boat

thingiverse

I designed this EDF boat after watching RCLifeOn's video on his custom EDF RC boat. It prints in two parts and requires a minimum print height of 240mm and dimensions of 190mm or so. There are two models: Mk. 1 and Mk. 2. I've printed Mk. 1, which is a joy to drive but may be too small for ponds with waves, as seen in the video. Mk. 2 was designed to handle waves better and is more suitable for the 64mm EDF. I haven't printed this version yet, but it should work flawlessly like Mk. 1 did. The main difference is that Mk. 1 is meant for driving on land while Mk. 2 isn't, but still could. The servo sits at the back and attaches directly to the rudder. The top of the rudder is secured to the EDF. Use a waterproof 9 Gram servo as the servo is submerged during normal operation. Glue the bow and stern together with epoxy, preferably classic JB Weld steel-reinforced epoxy. Most screw holes are set for M3 and M2. Create a watertight seal around the lip of the Cover Bottom using a rubber band. Seal the open portion where motor/servo cables route using double-sided adhesive tape. The two EDF models I used are below: 50mm Powerfun 4300KV (https://amzn.to/2NwNNlu) and 64mm QX-Motor 3500kv (I should have gotten 4300kv, https://amzn.to/2Z878yR). The video showing the 50mm model is at the end of this gallery: https://youtu.be/V42A0phzvP4.
