Rx and Tx Crystal

Hello,

It's me again, asking for more questions. I have to have to have a transmitter and a receiver crystal plugged into a transmitter and a receiver. They also must be the same channel (of course). The receiver crystal goes right into the to holes in the receiver and the transmitter crystal goes right into the transmitter's two holes.

Can't the robot drive without a receiver or a transmitter crystal?

In this guide at:

http://www.dimensionengineering.com/app ... _robot.htm

They never said anything about a receiver crystal or a transmitter crystal.

Hi there,

No, they don't mention anything about it, but if you follow the link to receivers from that page, you will see that the spec of the receiver in the photo of the page you mentioned says

Compatible Crystals GWS UM-1 receiver crystals only

I hope that helps.

Simon

BTW, Spektrum transmitters and receivers don't need crystals.

Thanks, that did help, I get it now. That guide was bugging me a bit before.

Blimey - I thought it was supposed to be a simple antweight!!

BTW, if I get bored over the ModelWorld weekend I may be persuaded to do my 'Build an ant in 10 mintues' feature....no promises though!

10 minutes!? It's taking me more then a year to make my first antweight, mainly because i don't have all the parts. 10 minutes with all the parts ready and a good chassis?

To compliment it I could do my break an Ant in 10 ms when its finished.
By the way will you have a covered arena.

Patdied, have you seen my "built a robot in 6 steps"? Although it uses servos, so it's a bit out of date.
