tonytiger88 Posted September 17, 2022 Share Posted September 17, 2022 Maybe im in wrong thread or didnt see it, anyway winter time here in Sweden has tons of snow so i plan on building a hovercraft, i built one last year but it had flaws using just styrofoam and RC plane propeller. this time i plan to add a air cushion and a EDF fan, im thinking of saw a square and use a PC fan, i found this cable https://www.amazon.se/dp/B09BQ9CJCL/?coliid=I3LC3S4Z1QUQ7B&colid=2J0C1P8RQJDIH&psc=1&ref_=lv_ov_lig_dp_it_im so maybe the PC at fill the air cushion can draw power from batterys balance lead. what do you think, is the idea good? I know nothing about KV so can you guys maybe advice about a powerful EDF and powerful PC fan. maybe this? https://www.aliexpress.com/item/1005003985566437.html?spm=a2g0o.productlist.0.0.655060d3agL8BJ&algo_pvid=a0f38c1c-cfd9-44be-b5e8-3a8ea1ed0dce&algo_exp_id=a0f38c1c-cfd9-44be-b5e8-3a8ea1ed0dce-0&pdp_ext_f={"sku_id"%3A"12000027644527969"}&pdp_npi=2%40dis!SEK!329.71!329.71!!!!!%402103399116633969930197598e6cc2!12000027644527969!sea&curPageLogUid=dKbUrWvqbP9o 1 Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted September 17, 2022 Share Posted September 17, 2022 (edited) You may well find the small motor in a PC fan just won't have the power you need. There is no such thing as a 'powerful' PC fan really. They are limited in votage as the power supply from a motherbaord is not that great either in voltage or amps. Now....your first build I assume just used a single prop for lift and propulsion? ...and you plan on using a seperate lift engine to fill the cushion and a ducted fan ( I guess on a directional controlled mount or with rudders ) to move and steer. It's a solid design strategy for a hover craft, but I would look at a second ducted fan to do that, not a PC fan. You need to be able to flow enough air for whatever size skirt you are going to have, as air basically spills out hte bottom constantly and hte fan needs to replace it. If you fan can;t move the air...the hovercraft is just ...er...a craft. No hover.

BlackSeaRC Posted September 17, 2022 Share Posted September 17, 2022 Do you actually require the complexity of a hovercraft? Most of the RC airboats operate quite effectively on snow with just the rear propellor for drive. Quote Link to comment Share on other sites More sharing options...
tonytiger88 Posted September 25, 2022 Author Share Posted September 25, 2022 Yea i think i skip the extra fan, too complicated and you must have fligth radio and i can only use one hand Quote Link to comment Share on other sites More sharing options...
