    This is my swing wing after pusher motor was fitted it can now reach speeds of 80Mph but sadly because i'm old and dumb I managed to bury it in deck but it will be flying again soon bit of fibre glass and filler repaint and she will be good as new.

    This started life as a silver GWS sky train but i have made various mods to it like brushless motors 3 blade props 3 cell lipo and added guns to the side as a gun ship, also cut the ailerons down and fixed the outer ailerons to a 20 deg upward angle to st

    This was after i rebuilt it following a crash front was a write off and snapped the fusilarge in half

     Timbo, back to begining GWS C47 AUW 1-3/4ib Two Type: A2208/8 Prop Size 3 bladed 5x3 GWS No. Of cells:3s 25c 2200mha Li-Poly, RPM/V:2600 RMP/V Max. efficiency:78% Max. efficiency current:8-15A (>74%) No load current / 10 V:1.3 A Current capacity:20A/60 s Internal Resistance: 62 mΩ Dimensions:27.5x26 mm Shaft diameter: 3 mm Weight:36g /1.27 oz ttwo simple 30amp ESC given the information that i have given, how would you do the math to check it was suitable on paper, or given the C47 what size brushless motors and battery combination and ESC's would do the job at the given all up weight of plane with the 36g motors, my line of attack was i had a buzz lightning and knew what the motor could do, so assumed motors would be ok in C47, if over powered some what, i also knew it would be ok with lipo as i had previously flown it with stock motors with that size battery, so i just got two motors and two 30amp esc the only differance being the extra  ESC weight which was not much and as i had saved a little weight with motors i thought it would not make a great deal of differance guessed it really.

    Sorry Timbo what i ment was given the information that i have given, how would you do the math to check it was suitable on paper, or given the C47 what size brushless motors and battery combination and ESC's would do the job at the given all up weight of plane with the 59g motors, my line of attack was i had a buzz lightning and knew what the motor could do so assumed motors would be ok in C47, if over powered some what, i also knew it would be ok with lipo as i had previously flown it with stock motors on same battery, so i just got two motors and two 30amp esc the only differance being the extra ESC weight which was not much and as i had saved a little weight with motors i thought it would not make a great deal of differance guessed it really. Hope that is a little bit clearer and enjoy your session up the Orm.

    On those motors Timbo, they are exactly they same as i have on my Buzz Lightning from Flying wings and i run that on same Battery size i get around 7-8 mins flying time, so assumeing that, would you think running two of the same motors i will get around 5 mins flight time. motors are Type: A2208/8 Prop Size 5 x 5 (speed APC) No. Of cells:2-3 Li-Poly, 6-8 Ni-Mh/Ni-Cd RPM/V:2600 RMP/V Max. efficiency:78% Max. efficiency current:8-15A (>74%) No load current / 10 V:1.3 A Current capacity:20A/60 s Internal Resistance: 62 mΩ Dimensions:27.5x26 mm Shaft diameter: 3 mm Weight:36g /1.27 oz And using 30amp ESC's, with the 3 blade 5x3 props with as mentioned all up weight. I would be interested to see how you would work it out.

    Sorry , wrong info there its an 3 bladed 5x3 GWS and it is a brand new lipo on its first charge so would that be the difference, i am using one of those what meters from BRC so would imagine it to be fairly accurate, it is a 25C batt, I'm not sure on this electric stuff yet but am trying to get my head round it, by reading these excellent threads and books but like i always say you learn nowt till you try it out, and have ago yourself. in my oppinion you only then start getting an understanding of how it all works i.e changeing prop size to see how it affects your performance and battery times.
  21. Roy Gallagher
    Yes Timbo i thought that so i have added 2mm of down thrust to the motors with washers on mounting screws, i can tinker with that, may need more, up to now the watt meter is showing 280watts @ 23.4 amps using the 11.1v 3s 2200mha with gws 3 bladed 5x5 prop,  AUW 1.3/4lb. Over 3/4 throttle though i am getting a lot of prop baffle may need to put a fibreglass master airscrew props on
  22. Roy Gallagher
    Yet another satisfied customer thank you Timbo problem solved. however what i had to do was turn on TX with full throttle, then plug my battery in with the ESC'S and motors all connected up and it bleeped 4 times, then i pulled throttle to low and it then gave confirmation bleeps and whalla they where singing sweet music together and in sink. would not have done it without ya mate again thank you, top man. they are fitted in my GWS C47 which is at the moment undergoing a full revamp as stock motors just dont cut it for me, and it just does not behave itself in air the way i would like it to, so i have cut ailerons short be 6 inches and added 5mm reflex to them at ends which can be adjusted, this to try and solve the problem of it nose diving when you shut off throttle and it's habbit of tip stalling at low speed, i will get it to fly nice if it kills me.
  23. Roy Gallagher
    thanks Timbo, will try that tomorrow and let you know the outcome.
  24. Roy Gallagher
    Now Timbo you have asked some thing there, by train i assume you mean program, no i did not ,i started one motor up on one ESC first with an identical motor i recieved from Flying wings while i waited for my two new motors of the same model, if that is case what do i need to do to train the little blighters.
  25. Roy Gallagher
    I am puzled here and am hoping one of our electrical gurus can help me, two simple 30amp Hobbyking ESC's two Hi model 2600kv brushless motors all wired correctly running from one 3s 2200mha battery. should run fine? yet when i throttle up one motors starts before the other and stops before the other all ESC's and Motors bought at same time. anyone any ideas because im pulling my hair out.
