jimmypeace Posted March 15, 2021 Share Posted March 15, 2021 Hi guys! I'm brand new here and fairly new to the whole RC thing. I used to dabble a lot as a child but never building my own and I really need some help now! I am building a hovercraft as part of a challenge from work and I need some advice on how to power it. I have a standard cheap amazon controller and receiver. Nothing flashy as I'm not worried too much about range etc. However, it does have six channels, so I can control the different elements of the craft. To provide suitable downforce, I have acquired 2 QF2611-4500KV Brushless motors in a turbine housing to drag air to the underside of the craft (specs below) Moor model: QF2611.KV: 4500 KV.Configuration: 9N6PShaft diameter: approx. 20.2 mm.Stator length: approx. 11 mm.Motor size: approx. 26 x 47 mm.Open circuit current: 2 A.Number of cells: 3 - 4SMax. Continuous power: 280 W.Max. Continuous current: 27 A.Voltage: 11.1VAmpere: 25A.Wattage: 278 W.Thrust: 750 g, 26.5 oz.Efficiency: 2.7 g/W, 0.1 oz/W.Channel barrel outer diameter: approx. 75 mm / 3.7 inches.Weight: 120 g. In order for propulsion, I am not planning to set a land speed record or anything but something to give it some oomph would be great. I basically need a solution to be able to effectively power the 3 motors, the receiver and rudder servo using as little weight as possible maybe. looking at using 2, 2200 mAh 3s lipo's to do this but naturally, I am open to suggestions. I am just trying to use some drone parts and donations in order to keep costs down. I'm 3d printing the chassis, the 1st revision seems a little on the heavy side so no doubt it will be revised, but at this point, I am 99% sure my electrical requirements wont change. Any help, advice or support on this would be greatly appreciated! As you can probably tell, my knowledge in this is very limited. Thanks :) Quote Link to comment Share on other sites More sharing options...
froggy8 Posted March 15, 2021 Share Posted March 15, 2021 the only ever hover craft i have seen being built is from @.AJ. maybe he can help? Quote Link to comment Share on other sites More sharing options...

jimmypeace Posted March 15, 2021 Author Share Posted March 15, 2021 Hi Guys! The hovercraft aspect, isn't really the issue. I'm just looking for a means to power the motors. in terms of ESC's etc. Any help would be awesome 🙂 Quote Link to comment Share on other sites More sharing options...
lorrylemming Posted March 15, 2021 Share Posted March 15, 2021 https://hobbyking.com/en_us/turnigy-plush-32-30a-2-4s-speed-controller-w-bec.html?queryID=bb986bb037ded03a3f3ceac36802d80f&objectID=82088&indexName=hbk_live_magento_en_us_products_hbk_price_stock_1_group_0_asc One of these for each motor, wired up to one battery in parallel would be the fewest components. Might be easier to run the 3 smaller batteries depending on your design. For the rx and servos remember to only connect one BEC. I've never used the ESCs above so not recommending them, just roughly what you need to look for. I'd suggest going up to 40 or 50 amp for a bit of headroom. Any rc plane esc of the right specs would be suitable. Quote Link to comment Share on other sites More sharing options...
