Hi Sharad,
It sounds as though you are getting some interference from the Glow Booster you might try using a filter on your servo leads. Also the the range problem my be due to the area that you are doing the range check in....anything such as a metal fence, a wall that is close to you, or metal poles close to you, anything that would reflect the signal back. Try a range test in a different area to see how this does for you.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
