Matt,

The record with turbine powered models to this point--be they retrofitted ducted fan aircraft or those specifically designed around turbine engines--does not support the postulate that .45 size jets are somehow going to just "fly apart", as was the implication, by virtue of being "turbinized." In fact, the top end speed on these models with an "appropriate" 7# or 12# thrust turbine will not likely exceed their speeds with the best .91 ducted fan power--and they certainly are not likely to exceed the AMA published speed limit. The fact is, actually, that a RAM 750 has already flown in a JHH Hawk ARF kit--and it flew very well--also very fast. The problem, of course, was unacceptable wing loading, so it's since been retrofitted with a more appropriate Wren MW-54. However, experience actually illustrates that the majority of new people tend to be more cautious in trying to make the proper choice when matching engine with airframe for the very reason that they are concerned about maintaining their investment over the long term.

I'm just wondering how it is that somehow the level of monetary investment in a jet project is supposed to equal skill level, as has been inferred here! Be that as it may, I believe you have rolled up a few yourself--and at what expense!
