Firstly, thank you for allowing me to benefit from your ongoing labour by making the instructions for this excellent crawler available.
Secondly, I am completely new to Technic and this is the first model that I am in the process of building. Looking ahead to finishing the model - hopefully over the weekend - I have a query about the PFs. You have 2 IR receivers for 2 XL motors and 1 L motor and an AA battery. I only have 1 IR receiver, presumably V2 because it came with a second hand 9398; this means that I also have an AA battery. However, I also have a LiPo battery. My query is whether 1 IR receiver would be sufficient for the motors with the LiPo battery as I could do without spending any more money at the moment?
I apologise if the answer to this query is more obvious than it seems to me, but it is quite a steep learning curve and I am only slowly finding my way into the collective knowledge of the Technic community. As this is also my first post, my apologies also if I have posted inappropriately.
Thanks in anticipation.
