My TA-05 requires that you trim off one of the servo tabs/ears/mounting holes on one side of the servo. What's the best way to do this without breaking the tab below it? This is what happened to the first servo I put in there... thankfully it was a cheap-o unit that I didn't really care about. I used my sprue cutters, I don't think they were delicate enough.

Try it with a dremel cutting disk and cut as close as you dare then finished with a file. Do this on that servo you didn't care about!

instead of cutting off the servo ear, try trimming some material off the ta05 chassis. you're using the stock TA05 moulded plastic chassis, right? i did this to my chassis and the servo fit with all 4 ears intact.

its easy to do with a dremel and a file. see where the servo ear will hit the center of the chassis and remove a bit of material there.

but if youre going to race in TCS or a similar series, check with the rules first. i think you are not allowed to do any chassis mods.

It's really not a big deal...that same ear gets trimmed off for lots of cars. It's the same one you trim for a shaft car.

I use flush-cutters (small diagonal cutters that cut flush), then trim it with an x-acto.

I broke one of the tabs off mine using flush butters. I would use a drremel and then an xacto.

You gotta get some better "flush butters". Sharp ones will go through plastic like a hot knife through "cutter".

Why don't you heat up the blade on an x-acto knife to trim
those tabs off ? Use a good heat gun,torch or cig. liter to
heat the blade up.
