I was wondering if anyone could give me some tips before i crash this thing. How should i set up a failsafe? Whats gonna happen when rx battery die? I have Futaba 3PK.
I know the question about switch was asked couple times here but no1 really gave a good answer. Should i use it? I know most of You guys dont bother with the switch, but how do You connect your battery ? Do You have to remove RX tray every time You want to connect battery to rx?
I know that those questions for most of You sounds lame but hey, i dont want to learn the hard way
I have the Futaba 3PJ, but you need a PCM receiver to take advantage of the failsafe. If you have a PCM receiver then just do as Sow says: follow the instructions in the TX's manual.
The battery lasts a long time, but if you don't have a failsafe and the battery goes flat, then you're car is off on a ride of its own!
It is best to recharge it after you've played for a couple of hours - best of all have a second battery pack, so you don't have to stop playing
Set the brake linkage so that when you press the throttle trigger forward the breaks come on straight away, but when you release the trigger, the brakes disengage. Set brake strength with the ATV setting on the TX unit - make sure you set it fairly low otherwise you're going to spin the car if you're running a one was, or if you're running the solid front, you just lock all the wheels. An ATV % of 30 is a good start.
Setup the throttle side, so that the slider in the carb is fully open when you pull the throttle trigger fully back - but check that it as you press the throttle the carb opens with the movement of the throttle trigger, i.e. doesn'T open fully until you fully depress the trigger.
Another check is to ensure the throttle is closed when you let go of the throttle - if not you need to adjust the centre point of the servo with your TX unit (see your manual). Also when you press the throttle trigger in the brake direction, ensure that the carb throttle move backwards - if it does, this means that the throttle isn't full closed when you let go of the throttle - again, adjust this with the centring function of the TX unit.
Make sure you set the setup as accurately as possible - otherwise the handling won't be so good.
Also a badly setup car may mean that for example the pivot balls aren't screwed in far enough in the suspension arms, which could lead to the pillow balls being pulled out in a crash.
I suspect a lot of the people who complained about the 710 being a Glass Car (where is our friend these days!!!) were actually too incompetent/lazy to fully setup the car and therefore some components weren't mounted as they should have been!!
Check the rear width is at most 200mm wide (measure with a ruler under the car - car on the ground) and that the left/right sides are both 100mm from the centre line.
The front should also be at most 200mm check this the same way as the back.
Have a read through the 710 FAQ, there are a lot of tips in there. Print it out and take it with you.
Take things easy at first, as the 710 will move pretty fast on full throttle
