Shaun Roberts Posted October 2, 2018 Share Posted October 2, 2018 Hi, I'm currently in the process of building an electric SLEC fun fly. SLEC lists an AXI 2826/10 as a good motor however they seem quite expensive at £85! Ive searched for alternatives but to be quite honest im not sure what im looking at. Could someone recommend a good affordable electric motor? Im not cheap honestly lol but dont have an awful lot of spare cash! Cheers, Shaun.

Nigel R Posted October 2, 2018 Share Posted October 2, 2018 ShaunI think this is about 4lb or so ready to take off?I Would suggest a D3548/5 motor from hobbyking.On 4s it Can easily be propped between 400w and 800w which gives plenty of scope to choose performance!

Shaun Roberts Posted October 2, 2018 Author Share Posted October 2, 2018 Thanks for the quick replies guys Still a bit wet behind the ears with electric motors etc Quote Link to comment Share on other sites More sharing options...
PatMc Posted October 2, 2018 Share Posted October 2, 2018 Any of the motors in this HK page should be suitable, just a question of balancing a lower kv one with large dia prop for better climb rate or a a higher kv with smaller prop for speed.

Nigel R Posted October 2, 2018 Share Posted October 2, 2018 What sort of performance are you after? Quote Link to comment Share on other sites More sharing options...
Shaun Roberts Posted October 2, 2018 Author Share Posted October 2, 2018 Hi, Would like enough power to vertical climb so was trying to stick close to what SLEC advise I used to be quite a good pilot.....but that was 15 years ago lol Found https://www.4-max.co.uk/po-3547-960.html which is the equivalant. To my untrained eye looks fairly well suited??? and at a reasonable price. Sorry for all the questions.....I'm learning slowly Cheers, Shaun.

Nigel R Posted October 3, 2018 Share Posted October 3, 2018 Ok, vertical I would guess (given the model weight) you will probably need about 600W output then. The 4-max po-3547-960 will be the same size and characteristics as the hobbyking 3548 type. They are sourced from the same place (XYH in China). I would go with the hobbyking motor here: https://hobbyking.com/en_us/turnigy-aerodrive-sk3-3548-840kv-brushless-outrunner-motor-1.html ESC, would particularly recommend the Turnigy Plush type: https://hobbyking.com/en_us/turnigy-plush-60amp-speed-controller.html I'd suggest 4S4000mah size lipo e.g.: https://hobbyking.com/en_us/turnigy-battery-4000mah-4s-30c-lipo-pack-xt-60.html and try an 11x5 (to start with). Up the pitch to 11x6 if that's not enough grunt. I use the same spec motor and ESC in a 5lb model. On an 11x8 prop it shows 800W output, and will (just about) accelerate vertically. Putting the 11x5 on will drop the power to about the right amount for your lighter model. Do you own a wattmeter yet? Absolutely essential tool - would advise getting one. You can easily adjust the prop to get the right power output with one of these things. They're a proper swiss army knife for setting up an electric model.

PatMc Posted October 3, 2018 Share Posted October 3, 2018 IMO Nigel's advised package is spot on, though if you have enough ground clearance for a bigger prop this 700kv version of the same motor would give better vertical at the expense of all out speed. BTW ignore the max power figures in both motor descriptions, they don't tally with the max current & voltage range. The 4-Max motor has several disadvantages compared with both HK ones, it would only take be able to use 3s lipo for the same dia props (which means lower potential power) or, on 4s, would have to use a smaller prop to stay within current limits. Also the motor shaft is at the "wrong" end, requiring use of the bolt on prop driver which can be troublesome if it's are a fraction out of true centre & it means ensuring clearance for the 5mm shaft that's projecting into the firewall mount.

Redex Posted October 3, 2018 Share Posted October 3, 2018 Hi Shaun I fly this model and is good fun. My setup is with and an E-Power GT2826/05 860KV brushless outrunner, JP EnErG Pro 60 SBEC, APC-E 12*6 prop and a Turnigy 4000mA 4S 30C Li Po.

Shaun Roberts Posted October 3, 2018 Author Share Posted October 3, 2018 Hi, Thank you all for the brilliant advice and tips They are all very much appreciated Think i'm going to run with all of Nigel R's components and see how she flies. Kind Regards, Shaun Quote Link to comment Share on other sites More sharing options...
