Hello, new Raptor 30 V2 owner here....this is my first nitro heli (been flying small electrics) and I have a few questions regarding servos. First of all, I realize the torque specs on the servos in question are a bit overkill, but I like having plenty of reserve.

1) How much difference will your really see between the upper-end Futaba servos in the $80 to $110 range (in particular, the S9250 ($100), S9252 ($80), and S9451 ($80))
Are these on a pretty even keel when it comes to accuracy, repeatibility, and zeroing?
2) Is it really worth spending $100 on the S9250 over $80 S9252 or S9451? It starts to add up when you have to buy four or five servos....
3) Alternatively, how about the S3050 with it's slightly slower speed of .20s/60deg? This one is about 1/2 the cost at $50....

Thanks for your time.
