Can anyone tell me is the TowerPro 9g servo's are good for a Trex clone?
I am looking for three cyclic servos under $10 each.

Any suggestions?

They will work. They won't work well. Go with the HS-65 that everyone uses. They are about $25 each. You will save over the long run. The helicopter will do what you tell it to do vice always chasing the trim and riskng a crash.

+1
If you can afford it go with the 65mg's
They will take crash after crash and just keep on working

I know guys, I have 65MG on all of my heli's

I am looking for a really cheap set that will fix in the trex frame.

no more than $10 each?

Maybe something from Hobbycity.com?

I am running the TowerPro 9G on my HDX 450. They are ok. Not as precise as the HS65 but they work ok.
They do tend to strip easily but are not a problem as long as you avoid overly hard landings.

Yes, as Missileman said. I run the tower pros on my two helis and while I'm sure they are not HS65s they do work well for me and yes they fit the trex clone frames.

what "Trex clone" are you working with?

I have heard great things about the EXI 450.
It was only $99, with freeshipping.

Looks the same as the Trex version and apparantly is compatable with trex parts.
All I want is for is a fuselage for slow ff and hovering.
