I have couple question about the kit.
If I have servos HS 645 can I use with EZ robot brain.? If I can than how many can I use up to ?
I am really interesting about using lipo battery? However if I use servo HS 645 than do I have to do any adjustment?
Last question, if I purchase I complete kit , which is include heavy duty servos. Are they same size as HS 645 servos?
