Yes God bless the 4th channel!The best part is it`s backward compatible with all spektrum protocalls even marine so I can use all my hk orange $10 recievers.Listed at $279.99 so my lhs gave it to me with tax for $242 so I saved $55. I ordered the cover for the display.I was looking at the flysky it-4 but the spektrum has no antenna to break off it`s got a shark fin,and the display is back lighted .The reciever will do 4v-9.6v and thier is an optional lipo for the transmitter.The spektrum has no drop down wheel and can not be changed to left handed use.Price wise it`s even with the airtronics mt 4. The mt4 has no backlight ,but there is a mod out to back light the display.The mt4 recievers are a bit pricey,it`s ok if you only have one platform,but for those of us who have a few platforms it gets costly.So God bless rcdad with the price of his kill switches.Love ya Brian.Oh ya the spektrum has a sd card reader so you can upgrade the sofware as they make it available.
