thanks for the response! yours is the best I have recieved yet,, sadly it took this long to view it cause I forgot to set the post to give an email when replied!
Thanks for the schematics! I dunno if they are going to be any use yet but I got them anyways and wll have a good look at the later.
Curious, what is the purpose of the modifications you are making?
Have you reverse eng'd the actual radio block yet? I am wonderign exactly how much of the rf block is handled by the rx1 IC? I have read that it provides a dc-dc step-up for the block but beyond that I really dunno what it does other than act as the decoder,, again, have had a hard time finding the datasheet for the parts (rx1/tx1).
For the coils, I have ended up just going with basically the same circuit as stock,, for the motor I am using a single output version of the dual dc driver. My current version has no rf at all because I have found no relyable info about the clever design,, I was thinking tp use a zigbee trx but really not enough room for such a circuit!

anyways, if any good info then I will post,, as well, am looking for any trades of rc equip- am willing to do custom electronics work/manufacture in exchange for whatever cool stuff you wanna get rid of. cheers, jd
