| Put in a small jet engine, then I'm sure it'll be a blast!
Today you can build very effective small jet engines, so it shouldn't be a problem technically.
As for the flying characteristics of the a/c, well according to the German pilots who flew and Eric Brown it handled very well and very maneuverable - no wonder with that low wing-loading.
__________________  We have built a total of about 1250 of this aircraft (Me-262), but only fifty were allowed to be used as fighters - as interceptors. And out of this fifty, there were never more than 25 operational. So we had only a very, very few.

| I would have a go with the Jet version, your starting to get me to change my mind, but the rocket is still a no go. | |

Country: | I think that one might be too small at only 1210 lbs thrust. Unless you're using 2. (in a layout like the X-4)
The ~22 in diameter of the J85 should be able to fit fine in the fuselage (depending on internal structure, but modifications shouldn't be too difficult)
The exhaust nozzle port would be allot wider though. (which shouldn't present a problem) Though not knowing the internal structure I dont know how difficult the mods would be, but if you're scratch building an a/c...
Or how about an old J30 (only 19 in and ~600 lbs for 1,600-1,700 lbs thrust)  ...

Country: | You might have problems with the J85 and the size of the nozzle required to keep the exhaust cool. A J30 would be good, but with a one man crew in a composite structure 1200 pounds may be perfect, especially if ine want to limit performance for safety reasons.

Country: | Are there working J-30's available? (I know there are J34's, some have even been modified for use on jet-powered race boats/hydroplanes, but J30's are older and I didn't think that many were built or produced very long compared to the long life of the J34, with there not being that high of a demand, the FH Phantom being the only production craft with them iirc and only 60 some were made)
And some J-85's diameter are down to 17-17.7" dia and 40-45 in length and only ~400 lb. (I checked the 22-26 in versions are with after burners with ~110 in length) Smaller than the J30's 19x94" and weight 660-680 lbs. Military Turbojet/Turbofan Specifications
But good call on safety limitations, along with the lightness of the structure of a modern composite construction replica.
