Speed Boat 3 RC

thingiverse

I broaden the front part of the hull so there it could may be possible to drive it also with an air propeller. To day I tested the air propeller but I had only a 2 cells lipo and that wasn't enough to make really speed. The powerful inboard outrunner was driven with 4 cells lipo and made the boat by far much faster. https://youtu.be/qRDI_Ux5wrI Update 07.31.2015 To day I tested the air propeller with another motor (STORM 1806 2300kv) and with a 4 cells lipo. Its much faster now: https://youtu.be/yqHt3sAv-RI But it isn't optimized yet. Full throttle pushes the bow down and breaks the speed. Attention Use the propeller mount with the protection ring only in still air, otherwise it will capsize for sure! That's why I designed the slim version "propeller mount slim". The hull consists of 4 parts, the longest is 180mm, or 140 mm if you take another combination. Anyway, I uploaded the complete hull, so you can slice it in pieces as long as you like. This is very easy to do with netfabb or another program. If you have difficulties, I can do it for you, but the smallest possible part is 130mm. https://youtu.be/VMiSrvlvjjw Update 08.24.2015 The third try was made with two propellers http://youtu.be/bLIIah6aCVQ https://youtu.be/sKNVVHtIEF8 Update 09.25.2015 A new video from a boat prited in PET by abcona: https://youtu.be/PcmQxUKALkk Update 12.20.2015 Uploaded sterntube test 7.4mm This is for a test print if you want to use a sterntube with 6mm OD. Update 01.03.2016 I added "hull back 190". You can still use a part of the interface. Just cut off about 25mm of the more norrow part of the interface. So you don't need to print the "hull back 140" and the "hull middle 50". Update 04.08.2016 "Nanafalke" did split the hull front 180 in two pieces (hull_front_40 and hull front 140) for smaller printers. The parts are now available for download. Thank you Sami Update 06.11.2016 I uploaded hull_front_270 Update Oct 24, 2016 I uploaded hull_bow_129 and deleted hull_front _40 So if you can only print up to 140mm you can use this combination: hull bow 129 hull front 140 hull middle 50 hull back 140 Update Nov 7, 2016 I uploaded hull_front_140_mod and deleted hull_front_140 Update June 27, 20109 For those who have printed the bug and hull front without a bottom layer, the interface_bow could help with gluing it together.
