Okay back to the point here...I got a Raidentech trainer for $61 shipped..it was (notice the word was) a brick the CG was written down as 5 mm back from the leading edge, I balanced it at the spar and it was ok ,,my .40 la would barely get the thing off the ground and on its first little mishap ,well its in a corner of the room by itself...nitromodels is a sister company trying to get out of the shadow of RTech,,but they have a BAD habit of advertizing a cool plane and then it being "out of stock"...they do had a sub forum in the ARF forum, but they dont seem too attentive to it IMO...Rog
