just got off the phone with my brother....checking on this servo situation....we had both ordered a JR flight pack around the same time, within a couple of weeks ....his came with 517's and a R600 reciever....mine with the new 700 receiver and 531's...the reason i mentioned "premium" is that is how JR describes them...honestly i don't think that a person will see any difference in "standard" flight between the 507, 517, 531's...

would like some response on this? Does anyone think the new JR DS811 digitals would be worth the money on the Flip 3D...or should i just stay with the 531's...maybe just buy one for the rudder....i have to say that i will spend the last penny i have for the best (within reason)....any input....
