h, saw your message about the rtr JQ..
the antenna is fine that short in 2.4 mhz, just try to insttal the wire above the reveiver if possible, but you won't have problems
if it interests you, I have a 3 mm cnc chassis for the RTR JQ, that produces the car to handle like the latest White JQ, because the chassis flexes more: cnc 7075 quality
I can get it to you for a price
the radiobox of the rtr/V1 is ok, it's just light weight enginering
