RCU Forums - HELP!!!!!

Im trying to save some money so I can get floats for the Ultra or Super Stick I plan to get. I already have a 5 channel JR sport computer radio from the Mustang PTS that I got last year. I think to save some money I will buy the JR sport standard servo with one BB which is 12.99 or the Hitec HS-322 Standard Servo that is 10.99 compared to 26.99 for the 537. Would these servos be ok for some newer aerobatics since I want to get a more aerobatic plane than my PTS. I could take the servos from the PTS and switch them for the new ones that I get that are a little cheaper. Would that be a good idea?:eek: I'll get the .46 two stroke and maybe upgrade later because I don't think I'll get a plane for a while after this one. And eventually I plan to put on floats so I can fly off the water since I live on the lake. Would Hangar 9's new 40 size floats work for that or are there cheaper ones that already come built? Thanks for any help I can get.
