Default RE: reciever effecincy vs. Rocket speed ????

hello guys
we couple of ideas rose here ) one about high speed and doupler effect, i guess just for curiousity i will try to check my Relativity chapter here
the other very interesting point here IS
that servos would not work if used for controlling fins ????? why wouldnt it ???
we have two points of view:
1) causeitflies-RCU SAID:

ORIGINAL: causeitflies-RCU

It depends on the speed and also on the G forces. Servos have been used for years on radio controlled rocket gliders with no problems and these are not illegal in the US. The reception will be fine but the servos may have trouble under a high G load.
and we have
2) rkramer SAID
"what are you going to control? a servo on the fins makes for a VERY short flight... (don't ask...) servos tend to hunt very small amounts, and this can translate into flutter very quickly at rocket speeds. not to mention since a rocket will never track perfectly straight, you have no idea which way is up, and therefore controls on the fins are basically useless..."

does this mean that if i use servos for such purpose , the idea would just fail ????????????
at least i can guess that we can have such powerful servos with hi torq that can sustane such load.???!!!!!
if causeitflies-RCU sees that it is just possible and doable , can you just giude me to the right combination of servos for example??


thanx guys and i would appreciate if ppl explained there point of view .
thanx guys and have a nice day
