David Davis Posted March 21, 2020 Share Posted March 21, 2020 My partner proved to be such a whizz on the simulator that in a moment of weakness I said I'd build a Super 60 for her. She wants it finished in pink but that's another story. I'm not going to use one of my beloved four-strokes in it and a two stroke would be too slimey for her so I've decided to power it electrically. Electric flight is not my strong suite but among my souvenirs is a "Twister .40" electric motor. This was made in France and is quite a chunky unit measuring 44mm in diameter and 43mm in the length. Anybody know anthing about this motor? Would it power a four channel Super 60? I was thinking of a using a 3S battery. If it won't, I have an Emax 2815/09 and an Axi 2820/10 in their boxes doing nothing The opinion of the cognoscenti is, as always keenly sought.

Dickw Posted March 21, 2020 Share Posted March 21, 2020 I remember Twister motors and recall they were OK, but I have very limited information. I found some information on a Twister 19/40 in MotoCalc but only that it is a 1000kV motor and weighs 175 gm (6.2 oz). what does yours weigh? Any other information on it? If yours is the 19/40 then it should be good for 500 watts at 7000 rpm on 3s and a 14x6 prop with a 60 amp ESC. Should be enough fior Super 60. Hope this helps.

Bob Cotsford Posted March 21, 2020 Share Posted March 21, 2020 Not much on google for the Twister motor. It sounds ok from the can size as that is a fair guide to power handling. You would want to be driving it from a 50 or 60A esc as I think you need to be looking for 40A or so for a vintage style performance. What's the AUW of an S60 - 4, 5lbs? Can you try running the motor screwed to the bench with a wattmeter to see if you can get 400 or 500 W out of it? Otherwise the Axi sounds ok.

Simon Chaddock Posted March 21, 2020 Share Posted March 21, 2020 David I think your motor is a Cyclon Twister 29 of 2000 vintage Full spec here If so the Twister 29 is considered a '40' equivalent at a max continuous current of 30 A and was considered capable of easily flying a basic plane up to 5 kg on 20 cell NiMh (6s LiPo) delivering 600 W. On a 3s LiPo you could only get 300 W at 30 A. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted March 21, 2020 Share Posted March 21, 2020 Do a wiring harness 2, 3s batteries, in series. Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 21, 2020 Author Share Posted March 21, 2020 Thank you gentlemen for your advice. Dickw, my motor is indeed the 19/40, the "19" being printed quite small on the case! I'll rig it up on a test bed when time permits and see what reading I get. It's pink too, she'll like that.

That gives me more confidence that David's motor is the 19/40 and the performance predictions I gave are reasonable. Dick Quote Link to comment Share on other sites More sharing options...
Dickw Posted March 23, 2020 Share Posted March 23, 2020 David While looking for something completely different I just came across instructions and other info for the Twister 19/40. PM sent. Dick Quote Link to comment Share on other sites More sharing options...
