Well Sean, I will ask you this : How do we KNOW what limits in terms of G, flutter characteristics, etc have been designed into the model. Has any stress analysis or wind tunnel testing been carried out, probably not and even if it had been how do we know when we are getting near to those limits, because until we have telemetry with IAS and load factor we are just guessing that too.

Every structure whether a bridge or an aeroplane can be taken to its failure point, in an airplane putting an oversized engine into it may quickly take it to that previously undefined failure point. Even when NOT overpowered we have heard of and I have seen some ARTF jets and prop machines fail in flight, deliberately overpowering them in order to obtain high speed, is in my view, for what thats worth, irresponsible and the possible consequences may do the hobby irrepairable damage.

Perhaps few of you in the US have heard about the high speed crash in Germany recently, caused in that case by a pilot losing control, for whatever reason, of a grossly overpowered machine. Only luck determined where the bits went.

I believe that jet operators are in general the most disciplined group of model fliers, but we just cannot be complacent and HOPE all will be well if we just stand idly by and continue to let this trend develop, a trend indulged in by very few but a few too many. We have this wonderful freedom to operate almost without any outside interference, I want to keep it that way and thats I'm prepared to speak up.

It interesting that no reps. have so far contributed to this debate.
