Mmmky for teh record I live in a city with lots of interference so at my local park I wasn't happy with the range of my TQ2.4 I was down to about 100 ft on flat ground and the range was intermitten which was frustrating. I tried different batteries with no success and even considered getting TQi. As a last resort I swapped our shortie antenna tube with one that was 30mm longer (little over an inch) and WOW what a difference, I manuvered my Summit around trees and up and down slopes at least 200 ft. Passers by were puzzled at who was at the controls or maybe it was driving itself . Now I can drive my Summit with confidence.
To me it's a no brainer so why Traxxas didn't use a slightly longer tube is beyond me.
Sidenote story: I really love my Summit... my local park has sloppy grounds, trees, basketball courts, volley ball courts, picnic areas, concrete walking paths, baseball diamonds, curbs, kids playground and my Summit roamed thru it like a prowler I was over 200 ft away in some spots and all this happened at dusk so the LEDs were kicking butt, Traxxas did a great job on this truck. BTW I was brushless so it blazed like a cheetah chasing prey
