Pulled 198 Amps on the 4525 a couple of days ago !!

Fredrik R · 02-02-2011, 12:06 AM

198 amps! Thats much!

Logged yesterdays flight. This motor got power!

f22warzone · 02-02-2011, 04:10 PM

would have thought that it would have kept the Hs more consistent with all that power
whats your gov gain?
Also were your lipo's kept warm before the flight?

That was a really nice save I didn't think you were gonna make it

skyfrog · 02-02-2011, 09:21 PM

Is the cause the carbon rod coming out from its threaded end? What options are there for prevention?... PS... Fredrik... you are one bad man Sir!!!! That was some serious skill under pressure....

Fredrik R · 02-02-2011, 11:50 PM

Have not touch the gov gain. It's a PowerJive 120HV. Could raise the gain little, but it feels good in the air.

The temp of the batteries were around 15-20 degrees C.
Ambient temp was -2 degrees C.

The carbon rod has been JB welded now. Booth ends

Had CA them before. So don't use CA and try to pin the rod!

+1 on the JB Weld, also file some nicks in the metal pushrod to give the JB Weld something to bite into.
