Mike,

I got it.

Googling and speaking with a friend from my club he proposed what he's is using, the s3152, which cost is logical, around 25Euro.

I think I'm gonna stick on them.

I have another question, if any friend here is using DX9 or 9303 what are the throws and exponential you guys are using ?
If any mix is also utilised or any differential ?

Best Regards,
Tasos
