RE: -=OFFICIAL HPI FIRESTORM THREAD=-
I had a spare one lying around, think it was either another stock one, or a spare one from my hitec servo. All I did was use superglue and made sure it was properly dry before I tried it. It has never budged, and I dont think you'd need anything stronger like bolts or screws, its only a weak SF1 servo anyway.
But yeah, play with the brass nut and adjust the swiveling linkage, and mod the servo horn and you will get the 100% travel you want. I believe that HPI didn't refine their linkage enough, and guessed 80% throttle would just be enough for everyone. If you have a digital radio, like a Spektum, you wont have to both doing anything, you could just extend the EPA by 10-20% to get the extra reach.
Nice to know there are other tinkers around! I spend many more hours stripping down my cars, cleaning and maintaining them than I ever do running them. I really enjoy that part of the hobby, and it pi$$es me off when you get kids who just pick up cars and thrash them and expect they do not require any maintenance to have them running well. I HAVE to know my car is set up perfectly, with no binding etc!
