The Futaba 7C comes with either 4 s3004 or 4 s3152 servos. The s3152 are significantly better, but the radio with them costs $30 more. If i put them in a Tiger 60, or something like that, is there any point at all to spend the $30 when i will notice basically nothing, or is it a good deal to get 4 servos that cost $20 more each for only $30 more total? What would you do? I mean $30 really isnt that big of a deal, but i dont want to waste money either. I fly only for fun, but i enjoy pushing a plane to its limits.

Either way im just gonna get another s3004 for throttle, since i will need 5 servos.

Thanks
