Thank you for the advice, it's always helpful and welcomed!
That being said I have actually bought some cheap servos off ebay with good luck, but these are just cheap get me by servos that are alot better then the stock tmaxx servo that can't even turn the tires off the ground.
And for the fuel, red max is what I've always run aside from top fuel, that being said I've been doing some reading on both fuels, and I've been looking into O'Donnell as I've heard you can get alot longer engine life with it. Also, I never really paid attention or cared to pay attention to how the different fuels ran, I will be observing for sure, and I'll see about maybe getting a few quarts of each to try, but I'm a basher, I like anything that's cheap, because I usually can't squeeze much lol.
as for lipo, I plan to convert everything to lipo, including my gt3b!
Tax time, is when those savor servos will mine.
I'll also test all 4 servos in the water when I get them first thing.
Reason why I get waterproof is I do run all year around, doesn't matter if it's 15 out with a foot of snow and still coming down I'll go out to have some fun

I'm also just learning tuning, something I was terrible at before and didn't care much for, I'm not so lazy this time around.
