thus far my best performance and reception on 5.8ghz is with stock whips, lol. tried CL and SPW and they weren't really any better, and my friend has some hugo ones and he says the same thing, bout the same as the stock immersion whips.
I do love the simplicity of 5.8. It pretty much always works, and i can fly with friends. Infact i fly 5.8ghz from inside my car. just stock whip on my predator goggles. Yeah the range is reduced, but for quad flying it's great. Stay inside, stay warm
