Steve T Posted February 21, 2014 Share Posted February 21, 2014 I struck up my E-Pioneer trainer for a test run after build. 50 amp esc, 3s battery, E-flyte 480 1250kv motor as sold by my local model shop, "ideal for that set up" they said. After 20 seconds at almost full power I smelt it and shut down immediately, and actually burnt my finger on the motor. It no longer functions! So 3s batt and 50 amp esc are undamaged, recommend a motor please ? Quote Link to comment Share on other sites More sharing options...
Colin Bernard Posted February 21, 2014 Share Posted February 21, 2014 Steve - I would be having words with the shop I think! According to the specs the E-Pioneer weighs 4-4.8lbs so you will need around 400W. Now I cannot find any reference to an E-flyte 480 1250Kv but there is an E-Flite 480 1020Kv and if this is the motor you have been supplied with then this is only rated at 275W and 22A - hence your problems. 4-Max recommend this for an E-Pioneer so go for this or one with similar specs Quote Link to comment Share on other sites More sharing options...
kc Posted February 21, 2014 Share Posted February 21, 2014 What prop did you use? Quote Link to comment Share on other sites More sharing options...
John C Posted February 21, 2014 Share Posted February 21, 2014 My Pioneer weights 5lbs and it needs a 4S lipo; I use 3300mAh 4S lipos which give about 11 minutes flying. I now use a EMax BL2820-07 (£18 from BRC) which is powerful enough to make fast recoveries when stalling near the ground or to pull away after bouncing badly on landing - very useful to have lots of power. It also allows you to fly nice large loops. With a 12x6" APC prop it gives 700W (46A) when the lipo is fully charged reducing to 500W when it is nearly exhausted. The thrust with a fully charged battery is about 5lbs. Quote Link to comment Share on other sites More sharing options...
Steve T Posted February 22, 2014 Author Share Posted February 22, 2014 Thanks for the replies. The set-up was 50amp esc, 11.1v 3s 3350 lipo, 11 x 5.5 prop and the motor, you are correct it was 1020kv. I will change the prop to 12 x 6. and go with an Emax motor. Thanks again.
