Stephen Grigg Posted February 25, 2010 Share Posted February 25, 2010 I bought this model about 18 months ago,put it together and fitted a rather large electric motor from my first build aDagostini Spitfire I was going to convert to electric.Its aJP outrunnerC5020-14 670RPM/V Brushless powered by a 5C 25C 18. 5 V3900mAh (5S1P)25c continuos97amp 50C Bursts 194 ampLipo.When completed the C of G showed a very Nose Heavy model.So its been sitting in my bedroom ever since.The other evening I worked out the Space Walker didnt weigh much more than the E - pioneer I had.This evening some delving around found the Pioneer motor aHi Model Purple from BRC the sp controller and battery,a Rhino$c 3700 20C 14.8 volt.The combined weight saving is 250 grams .Ive fitted the motor and have a small amount of work to make it flight ready.Im hoping tomorrow I can check the C of G and see how things have improved.The future will then see what can be purchased as a home for the Spit Motor Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted February 26, 2010 Author Share Posted February 26, 2010 The motor in place These last 2 photos show the differing size of the motors that Ive swopped.The C of G doesnt appear to be to far out now about right I would say which is what I wanted to achievw.Only the speed controller and receiver to fit now and a small amount of hangar rash on the rudder to recover Quote Link to comment Share on other sites More sharing options...

Stephen Grigg Posted March 5, 2010 Author Share Posted March 5, 2010 I agree with that Martyn,Mine is closer to being ready to fly than its been for 18 months ,Just need to decide which speed controller.Probably a 60amp it was using in the Pioneer.I know I have it programmed correctly to the motor.I did have problems with it but programmed it with a programme card and that cured its problems Quote Link to comment Share on other sites More sharing options...
gary w Posted March 5, 2010 Share Posted March 5, 2010 I would go for a 60amp esc, 13x6 prop on 3s about 450watts or 12x6 on 4s about 530watts should fly that very nice on either So when is the maiden then??? Quote Link to comment Share on other sites More sharing options...
Stephen Grigg Posted March 5, 2010 Author Share Posted March 5, 2010 Your workings out are about spot on E_-Flight Iwas using 3700 4cell getting 455 watts when in the Pioneer.Ill probably wait a few weeks.Ive a few maidens to do, and a few that have only flown oncw also in preparation for the year Quote Link to comment Share on other sites More sharing options...
martyn sharp Posted March 5, 2010 Share Posted March 5, 2010 Yep I'm using a 13*6.5 on a 3 cell but i have got a couple of 4 cells so might try them if I need more power and 60 amp as you say E-flight looking forward to flying it .
