Default Throttle Servo Hook-up

So I have some really basic questions on hooking up the throttle servo on my 1/5 FG MB-pro since there are no real instructions on how to do this.

My questions are as follows.

Is there supposed to be tension on the return spring on the throttle pushrod?
If so, how much?
I noticed that once I hooked up the throttle pushrod to the servo the return spring on the engine is not enough to fully close the throttle. Does this mean there is some binding or something?
Would you just use the fail safe from the radio (Nomadio React) to close the throttle and engage the brake if something were to go wrong?

How do you set up the brake pushrod?
Is the brake supposed to be fully locked when the servo is at neutral?
It seems if you have the brake setup to use travel once the throttle pushrod is closed then you will have some binding of the linkage... Sorry for that explaination.

Again, sorry for the basic questions.

I don't know why no one has responded to your post. This forum used to be full of knowledgable blokes willing to help....

You need a little pre-load on the return spring but not a lot, the servo will buzz if you overdo it as it fights to keep neutral.

Can you adjust the end points on your radio? Mine are set so there is more servo travel for the brake than the throttle.

Thank you so much for your response.

I agree about this forum. Lots of people looked at the thread, but nobody responded.
Maybe it was too easy of a question or people want to argue about whichh is better the Baja or the FG.

Thanks for taking the time to answer.

There is a thread on Failsafe that is ongoing right now. Considering the speed and weight that these beast travel at, A failsafe is a really good idea.

If you go to teh FG website, there is a few PDF files you can D/L and there are pictures of how the proper setups look. They really are not super helpfull, but something is better than nothing. I printed out everythign I could find, and now have a nice "FGMT MANUAL" in a binder.

Dave,

Thanks for the input as well.
I also have a binder that I have started. I've downloaded about as much info as I could find as well.

I've got a Nomadio React radio and I am using the built in failsafe feature of the radio.
I agree that these beasts could cause some damage if they get away from you.
