2 brand new proto3 engines. Both easily added to the remote but one engine's smoke unit fan is so noisy it almost over rides the engine sounds.
I tried saving the master remote to the computer. It took a while but eventually got there. Here the bad part, when copying to the other remote s (8 of them) 2 engines were missing and one name was missing although the ID was there...( No error messages). I going to try again but this time have a pocket full of new batteries. I finally gave up and came home in disgust... Maybe try again Friday.
