My only expirience with VMAR has been looking at one in the LHS. I was not impressed with the construction all and would not buy one myself. As far as I know two guys here had VMAR ARF's a while back. They both had structural failures within a year of purchace and both were destroyed in the resulting crash.
I looked over a trainer in the LHS here and it looked like the worst built plane I've ever seen. I would definetly not buy any VMAR ARF after seeing that trainer.
