Firstly there was an opionion asked for, so thats what I gave. In response to piper I would say to each his own. Never once did I say that it wasnt possible to learn on a 25 size plane or that it isnt flyable. however I do think I speak for the majority when I say although possible and given the right plane eaiser than some that a 3 channel .25 size plane opposed to a 4 channel 40 size is much more difficult to learn on and it adds one more step in the trainning process by not having the use of alerions and needing to be trainned when that aspect is sought out by the modler at a later time. But again its all personal prefrence and again everything in here is based on opionions. So theres another opionon I am sure there will be more. And lastly I must say that in a given situation where the aircraft is stalled or stalling which all do a plane with alerions is eaiser to recover than a plane with just rudder and elevator. Or maybe I need an explanation on how you would recover a plane that has tip stalled to the left on a low and slow pass with no way to right the wing. Again as mentioned in my original post it depends on what type of flyer you are. You may never get that close to the ground except to land. And I never used the word "proper". I am not bashing but merely defending my opioinon that someone feels is not valid we are all accostomed to what we are used to and to some if thats all they know then it never is a big deal to them. I dont only speak from an opionion stand point even though I have never flown that particular 3 channel plane I have flown 3 channels before. And my comparson was based on going from a 4 channel trainner to flying a 3 channel trainner. And IMO its harder with the 3 channel.
