I confirm it is an ESC issue.
In some ESCs brake comes on for only a short time (to stop the prop) and then
goes off. Usually a folded prop says folded and all is okay. Have you got a
rubber band around the blade roots to keep the blades folded?
Kind regards,
Neil.

Subject: Issue with prop brake on powered glider
Hi there
I would appreciate your advice please. You come highly recommended from one of
my flying buddies!
I have an 80 inch wingspan glider with a Hacker brushless motor. It has a Ripmax
Quantum 40A speed controller and I fly on a 3S 2200 Lipo. The receiver is a
futaba R3006SB with futaba 10J Tx
The issue is that the prop brake has recently started working only
intermittently. You can hear the brake come on as the prop stops suddenly, but
then 75% of the time the prop windmills and slows the glider down so that it
descends much more quickly then when the prop folds.
I have tried recalibrating the throttle and that hasn't really made any
difference. Also I have got the correct program card and have set it to brake
on, but to.no avail.
I'm assuming it can only really be a speed controller issue as everything else
is working perfectly?
I would be happy to purchase a new speed controller from you if you felt this is
indeed the issue.
Thanks so much for your help on this in advance
Kind regards
Simon Robinson
