HS-5945MG and external fail safe
Hello,
I recently purchased a HS-5945MG for the throttle / brake servo on my monster truck. I mainly chose it for the torque rating. It did not work with my in-line fail safe. The servo would appear to be powered and I believe centered but would not move. Hmmm.. perhaps the internal fail safe was engaged due to a voltage drop? I do not need to program anything else so I would rather not buy the programmer just to set the fail safe.
I am wondering if the current draw is too high for the fail safe or is the problem that the servo is digital. I am thinking that the current draw is the problem because the fail safe got hot and the set button no longer works. Will this servo work with in-line fail safes and if so does anyone know of a high current model?
I am looking at an EMS Servo Failsafe: [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCJD4&P=7]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCJD4&P=7[/link]
and [link=http://www.emsjomar.com/SearchResult.aspx?KeyWords=failsafe]http://www.emsjomar.com/SearchResult.aspx?KeyWords=failsafe[/link]
This one looks like it has not been miniaturized with surface mount parts so I would think it could handle more current.
I have replaced the 5945MG with a 945MG and the fail safe is working (except the set button)
I am using a Futaba 3PM radio and its stock receiver.
P.S. here are some pics of why I need good brakes..

RE: HS-5945MG and external fail safe
What are you using for battery power?
We have data on record that suggests many after market gadgets don't work well with OEM products. You may have such a problem.
If you want the failsafe activated check with the Local Hobby Shop, other modelers or send it to Hitec with a request, theres no charge for programming.

RE: HS-5945MG and external fail safe
Thanks, I am using a hump pack NiMh, I will try my NiCd. I had 3 HS-5945MG, 2 for steering, 1 for throttle / brake and a plain futaba servo for reverse shifting.
I will probably just use the 945MG until I can get my HS-5945MG programmed.
