ok. I got some rather large & wide Proline Super Swampers for the Nero. Took it out yesterday morning and immediately realized that I needed to throw in my stronger servo. So I got out the manual and followed step by step. Got to the part where the stack " drops out " and well.... It didn't. The motor is too long and even when I removed the long attachment to the servo crown - impossible to get it out. So I stopped and put it all back. Turned on the truck to make sure everything's ok - pinion not lined up right after putting everything back. ARGHHHHH!!! Took it to Bruckner hobbies to install the servo. Wondering if anyone has a link to a YouTube step by step on this " easy - 5 minute procedure " lol. Also - the pro lines ballon so much they ripped both front tires. I reglued them and they held yesterday AM. I saw on YouTube this guy mentioning using "gorilla tape" to reduce ballooning ? Anyone know about that?
