Re: Electronics questions
Yes, you can do exactly that, if you like, though if you want to be on the safe side with current draw on the track drive, maybe think about stepping up to the next biggest Sabertooth ESC, if money permits.
I would also think about using the blade and ripper servos as actual servos, with no ESC running them. Unless you need more travel to raise and lower the attachments. You can always increase the travel/throw of the servo by using a longer servo arm, with the attaching linkage out to the furthest hole, though you'll loose a little leverage (torque). If you run your blade and ripper servos with an ESC, there will be nothing to stop the servos from rotating past or over center, except you the operator, and that may or may not matter. It's something to think about though.

Re: Electronics questions
I thought he said he was using Firgelli actuator rams for blade & ripper.

Re: Electronics questions
Lil Giants, your right. I would like to use the firgelli rams to operate the blade at least, and I will probably use a servo for the ripper. I want the blade rams to look as clean as possible!! Thank you all for the info and putting up with mass amount of questions, you guys rock!!

Re: Electronics questions
Ok guys, I have another question...I converted the drive servos to run without the internal ESC. Here is my question, will I be able to reverse the polarity of them with the radio or how will I do it? Right now they both spin the same direction but obviously when I mount them they will be facing opposite directions therefor spinning opposite directions. Im lost and want to know if Ineed to do some re wiring before I glue the motors in place.

Re: Electronics questions
In this case you should be able to reverse the polarity to the motor that you need to spin the opposite way by switching the wires on the motor terminals. There are other ways to do it too, but this would be the best.

Re: Electronics questions
You're welcome! I'm quite a ways north of Racine. I'm in the central part of the state, in a small town called Mosinee.

Re: Electronics questions
So here is another question lol...I am looking at buying this radio:
http://hobbyking.com/hobbyking/store...Firmware_.html My question is what is the difference between "Mode 1" and "Mode 2"? |

Re: Electronics questions
Which side the throttle ch would be on. I can't remember which is which for mode 1... I think it's on the right. It's meaningless for our radio programming needs.

Re: Electronics questions
Alright, thanks!! I may stick to something like this then until I get more familiar with this stuff as I go along.
http://hobbyking.com/hobbyking/store...x_Mode_2_.html Whats the general consensus on this? |

Re: Electronics questions
Mode I has the throttle on the right. Mode II has the throttle on the left. Mode II is the more typical North American radio configuration. Usually it's not a huge deal what you get, for land vehicles, but for an aircraft, it can make a big difference.
The Hobby King radio you have a link for is a very basic bare bones radio. It doesn't leave much room grow with or program, but it's dirty cheap! I think I've seen a couple guys on the forum use these.

Oztruck, can you send me a link to that Radio?

Re: Electronics questions
Also, are you using the Ebay ESC's to control your drive motors? I removed the internal electronics as you stated you did and was wondering what type of electronics you have under your hood.

Re: Electronics questions
Oztruck, could you show me how you wired all your ESC's to the battery and receiver?

Re: Electronics questions
So you have one mounted in the blade ram as shown in the photos and the other mounted on the support arm for blade to tilt it? Are they micro servos?
