RE: Extreme Flight 87" Yak 54 - Build & Fly
I have switched the connectors to standard servo connectors (I think I got that info from Wayne way back when I was thinking of getting a Yak).
I've switched out everything I could switch out (batt., regs, plug), bypassed everything I could bypass (used a 4.8 nicad batt, passed the kill switch, changed on/off switch. Still to no avail.
It appears I am getting intermittent or no spark so in talking with DA they said to send it in and they would check it out. I'm also borderline with having the new mods, (my serial # is right around the time they started switching.) so they are going to look it over and make sure everything is up to date.
