[highway 101]

I am completing an EF 88" Yak with electric power. I have an older power expander and a super-reg which I could use. How much lighter would the power-system be than the separate components? ( don't need the kill switch obviously). I will be running a JR 9303 2.4 system with lipos for the receiver/servo power (no vibration!) I couldn't find the exact weights of the power-system set up on the website. Thanks in advance,

Mike
