I've built this one a few years ago and it was intended for a turbax fan unit, but I've bought a turbine before finishing it..... would be perfect for a wren 44 or the new generation of electric fans.
The plans was from Philip Noel, but I don't think that he ever released them. (thanks Dick!)

The airplane is really sleek and the space inside is very limited. If you don't make an inlet liner it will be ok and you'll be able to place the tank at the CG location.

I've sent a mail to a full size Super etendard/Rafale pilot (also a jet modeller) to get an accurate answer about the tailplane!
