RE: help needed
important that you guys get together and discuss what it is you'all want to do in combat. You need to come to some sort of an ageeement so that you will all be flying similar classed planes. You could go straight to the current standard SSC planes, but if you'r not planning on competing here in the states, these may not be the best for you. Do you guys just want to encourage local combat and have fun, or do you want to get ready for RCCA compettion?
For example, for starting out, I would reccomend that you start with planes that weigh a minimum of 2.75 lbs with 0.15 engines. You may want to consider going will all foam scale warbirds, or all open type design planes. You may want to standardize on an engine/prop combo, etc. You may want to standardize on all coroplast (SPAD) planes, etc.
If I was starting from scratch, and all things were equal, I would reccomend you go with a 1/12 sizish scale foam warbirds like the JK aerotech planes- these are tough little planes, although they wouldnt be competitive in todays RCCA SSC.
