Lunch-time flyer Posted February 13, 2015 Share Posted February 13, 2015 I've just dug out a 30 year old phase 6 from the attic... stuck a motor in it to see what happened... one flight later and a burnt our ESC says I didn't have a big enough motoe set-up... My question is: is this worth converting to electric power? It's heavy already... so any addition has to be very powerfull to make it worth the effort... and eventually I want it to hold a camer too so there's more wieght there... So ideas for a set-up - or just leave it - it ain't worth it ! Wingspan 66inches wing area 540 sq in. wing loading 11oz/sqft weight 42oz http://www.chrisfoss.co.uk/#/phase-6/4538950472 Thanks Quote Link to comment Share on other sites More sharing options...

Lunch-time flyer Posted February 13, 2015 Author Share Posted February 13, 2015 hmmm don't do petrol, but it was smoking a bit from the initial flight Quote Link to comment Share on other sites More sharing options...
Matt Jones Posted February 13, 2015 Share Posted February 13, 2015 I saw a guy flying one last year that he'd also converted to elecric, I have to say it went really well Quote Link to comment Share on other sites More sharing options...
Lunch-time flyer Posted February 13, 2015 Author Share Posted February 13, 2015 that's encouraging... Quote Link to comment Share on other sites More sharing options...
Matt Jones Posted February 13, 2015 Share Posted February 13, 2015 It was heavy though like you say and you'll have to be considerate with it, no abusing the elevator. You could see the wings flex a lot under 'G' but it did seem to fly well. Quote Link to comment Share on other sites More sharing options...
kc Posted February 13, 2015 Share Posted February 13, 2015 Everyone advises using a Watt Meter to see how many amps are being drawn to ensure it is well within the capacity of the ESC. This would have saved it's cost if it saves just one ESC.......... Quote Link to comment Share on other sites More sharing options...
Lunch-time flyer Posted February 13, 2015 Author Share Posted February 13, 2015 I do have a watt meter but I didn't use it It's the same setup taken from a lighter glider I have, so I thought it would be OK (same prop etc) - the real problem was I ran it full speed nearly all the time...!!! As opposed to short bursts.... doh! Quote Link to comment Share on other sites More sharing options...
kc Posted February 13, 2015 Share Posted February 13, 2015 A bigger ESC and more cooling then! Quote Link to comment Share on other sites More sharing options...
Lunch-time flyer Posted February 13, 2015 Author Share Posted February 13, 2015 not really as the motor wasn't man enough for the job even at full tilt - I was after suggestions of power setups or coments to give up on it... don't want to buy a new motor for no return, but if someone's got a good idea os the scale of setup I'll need it might be worth considering - and as I said I want to add weight too...!

Pete B Posted February 13, 2015 Share Posted February 13, 2015 I'd say something like a 3542 100Kv motor such as this, a 40A ESC on a 3S pack, with a 12x7 folding prop should give you in the region of 400W, which will be plenty with a bit to spare. I'm not into hotliners but I think that setup should give you a respectable performance. I had a similar setup in an old, heavy Super Grone and it worked well - until I entered an oak wood inverted... Pete Quote Link to comment Share on other sites More sharing options...
kc Posted February 13, 2015 Share Posted February 13, 2015 I am sure Pete meant 1000kv But is a 40 amp ESC enough? I reckon 60 amp would be better. Quote Link to comment Share on other sites More sharing options...
Pete B Posted February 13, 2015 Share Posted February 13, 2015 You're correct, kc - thanks for spotting that! I was pulling about 37A static and, being the climb-and-glide type, I tend not to hammer the ESC too much. I've found the Hobbywings very reliable even at the limit, TBH. A 50 or 60A would certainly give a little more headroom Pete Quote Link to comment Share on other sites More sharing options...
