What I'm trying to explain is that it isn't necessarily supposed to go on at a 90 degree angle with the trim set at 0. That's the purpose of a trim setting. It doesn't really matter if the servo horn goes on at a 90 degree angle with the trim set at 0. If it doesn't, you just TRIM it so that it does. Simple enough really. Do you understand now? Or do I need to explain it some more?

Losi tells you that because that's where it is supposed to be TRIMMED to. As in that's how you're supposed to set it on your radio. It doesn't say anything about it being 90* at a 0 trim setting. That's why they tell you to have it trimmed to 90*. Because it isn't always gonna be 90* at a neutral trim. Again that's the reason for a trim adjustment in your radio.

Your Hitec servo centers perfectly too. A servo that doesn't center properly is a servo that doesn't return to the same place every time. If your Hitec returns to the same spot every time, regardless of the trim setting or servo horn angle, then there is NO problem with it.

I always use a dab, for good luck and all.

oh i , see yea i adjust the trim to make it track straight anyways and the wheels to return back there where i have to trim at .

although, the $60 diginal hitec servos do have a problem with centering badly after a while or so. they most use cheap motors in the ones that are way cheaper.

Default Here is the right screw....

http://www.amainhobbies.com/product_...-Head-Screw-12

It's a 2.6mm thread.

Best price I've seen, and you get several screws. The hex head is for a 2mm wrench so you can get it tighter than those horrible phillips screws, just a dab of thread lock and your set...I recommend using a washer under it if you use plastic servo horns just because.....

some people hate to adjust the trim while setting up the car. i understand because many of my friends are like this. they want to adjust the trim only while driving, if its your case, you have the SUB TRIM option. set your normal trim to zero and adjust the sub trim till you get the 90 degrees horn.

well the reason they run them is for the speed of the servo... they can afford to replace them every race. they have the servo savers locked down and with under 200 oz they wont last long at all...

im going to start running over 350oz on buggy and truggy...
