I agree with this. Profile 3D planes are basicly 3D trainers. It is easier to perform the High Alpha manouvers with a profile.
However. Profiles are light weight and extreamly fragile... as are all 3D planes. They will not take a lot of abuse and If I had to pull a reasonable statistic out of the air I would say an R/C pilot is 99% more likely to completely destroy their second plane as opposed to their first trainer. This is primarilly due to the fact that you are now cut loose on a more aerobaticaly capable aircraft and you want to see what you can do... This usually ends with the pilot learning what he can't do yet in reletively short order. For a second plane I would highly encourage you to pick up an ARF for less than $100, used from a fellow club member if possible. Odds are pretty good you will destroy it but you will learn from it.
Okay maybey only 85% more likely
