Hi all, my son has recently purchased a Hyper 10SC roller, and has started to order everything to get it RTR, but we are stuck on what kind of servo we should get and would like some advice, he intends on racing in the Short Course control class. Here is the gear we've selected so far if this helps

FlySky GT3b Tx/Rx combo
Novak Havoc Spec BL ESC/SS Pro 10.5 motor combo


He is not looking to spend anymore than $80 but if there is no option for that price i guess he'll have to save a lil more. Any help and advice would be greatly appreciated, thanks in advance......
