I definately wouldn't cut it, especially before you do the math on it.

468/freq you are using, and that will give you feet, probably something around 6.5' for a half wave antenna. The receivers can either be 1/4 or 1/6 wave, so then you take that number you got and convert it from 1/2 to either 1/4 or 1/6. That is gona be the descrepency between the two antenna's.

for example say you are on ch50, or freq 72.790, that works out to be 468/72.790 = 6.43' or 77.153", so that's 1/2 wave, so to get to 1/4 wave divide that # by 2 and you get 38.577" and for 1/6 wave you divide the 1/2 wave # by 3 or 25.718"

I definately would not cut that =)

BTW I learned this from vec over on bladecprepair.com

"If you divide 468 / frequency, you get the half wave length of your antenna. If you were to take 468 / 75.890 = 6.16 feet. The antenna's on the helis are normally about 2 to 3 feet long, which makes the short wire on the receiver a 1/4 wave, or even a 1/6 wave wire. You could wind a third of that in magnet wire around a wooden dowel rod, and achieve the same thing as a base loaded antenna, having the wound part about 4 to 6 inches away from the receiver, and a solid spring wire antenna 1 foot long attached to the end of the coil. And when you do your calculations, be sure to include all the antenna wire from where it goes into the receiver."
