Hi,
actually i dont know many early wartime planes that did reach 290mph IAS or TAS in low level!! Since 290mph is good below a critical mach number in low to medium alt, i guess the flight restriction of 290mph is IAS related, but i doubt it will break appart. Probably this restriction include the typical extreme high safeness for civilian avaition.
The Spit1a, HurrI1 and Bf109E already had problems to gain this IAS in a level flight. Haw75, I-16, MS406, 110C, Fokker DXXI and most of the bombers dont got that fast(IAS).
I dont know this jet engines, but jets in general keep their thrust in higher altitude and a glider airframe also is somewhat perfect to archive relative high speed(as long as the critical mach dont get reached) in high alt, therefore i can imagine this glider will be as fast as most early WWII planes in higher altitude(10000-16000ft).
Althought Reynolds did overreact, like he already wrote, he wrote: "A Warbird MIGHT, depending on whether the fox has just come out of a dive, and what warbird it is. Now, these arent incredibly powerful engines, but I venture to say, once they are added the Fox will outrun, any early war plane."
This sentences dont seems to be ready and looks like bad formulated, but imho they maen: "with the jets added the Fox might outrun any early WWII fighter, depending on whether the fox has just come out of a dive.. ."
Despite the strange overreaction, i can imagine Reynolds is right!!
Would be interesting to know how many fuel can get added and how many thrust the jets provide.
