Rocker Posted November 28, 2017 Share Posted November 28, 2017 I have two Durafly Vampires .The first one fly great ,takes off and has ample power .The 2nd one has no EDF in it so I took the EDF out of the first one and put the EDF in the 2 one but it struggles to take of and is well down on power .This is the same EDF that powers the first one.Strange same engine.Could it be the ESC in the 2 Vampire is not up to it ,It is the only thing I can think that would make the same engine run with less power .I do not want to take the ESC out of the first one .I know everyone will say well leave it in the first Vampire but I am interested to know why it will not power the 2 Vampire. Is the ESC the problem here I will be interested to find out. I hope you understand all that Quote Link to comment Share on other sites More sharing options...

Capt Kremen Posted November 28, 2017 Share Posted November 28, 2017 Forgive me if this is obvious, but is the esc in the 2nd airframe operating at its full range? If you can connect it to a wattmeter you can run it at Max / wide open setting. Also you can compare the two esc and their operating current voltage etc. Just a suggestion ...😋 Quote Link to comment Share on other sites More sharing options...
Bruce Miller 2 Posted November 29, 2017 Share Posted November 29, 2017 If it's not giving full power have a go at setting the END POINTS in the ESC. Typically this involves powering up at full throttle position (restrain your plane and remove props if applicable) and waiting a few seconds for some audible signal then lower throttle to minimum setting awaiting more confirmatory beeps then you're done. Worth a try as it can do no harm and is very quick. Do check your own ESC manual or look online for other ESC settings to experiment with but usually the defaults are okay.

Piers Bowlan Posted November 29, 2017 Share Posted November 29, 2017 As stated above, it is most likely the end point adjustments, can you open the throttle more if you move the trim? Also just check all the connections are good as you may have a dry joint that has only become an issue after the 'open surgery' EDF transplant! To ask a silly question, the fan is not touching the shroud at all is it? Some of them are slightly flexible and can be distorted when glueing in place. Just my 2p worth, hope you get it sorted.

Andy48 Posted November 29, 2017 Share Posted November 29, 2017 Could it be the timing settings for the ESC? Edited By Andy48 on 29/11/2017 20:13:25 Quote Link to comment Share on other sites More sharing options...
