I have 301's in my F-15 and 701's in my topcat
same gear except the 701's are set up to accept 7/16" struts, sorry use the 701's for the turbine version f-15. U will have to get Robart to make you a set of F-15 struts to fit. The stock TGA/Robart struts are set up for "wire" at the top. Arrrrrrrrgh
I use 4 layers of glass in my conformal tanks 1 of 1.5 and 3 of 4oz . Bullit proof.
