Thanks for let join the forum,so I’m doing some changes first to cut the inlets to allow to move the top and bottom tanks back as possible +some extra reinforcements to the elevators formers and main wings formers,make sure that they mark the elevators left and right the airfoil should be up side down the curved side down this will help the straight flight and take off with less elevator up ,this will also prevent to over stress and flutter to the elevators will post pictures with detail installation.

What are you guys using as the CG. The "plans" provided by Skymaster is a combination of different models. It says 90-110 mm behind the leading edge of the wing. On my model that puts it at the front bottom of the engine hatch cover. Is this correct?
Note that I did a similar modification as Sysiek showed above to move the main fuel cell backwards somewhat so it is not all in front of the CG. I have not decided yet what to do with the small header tank provided. I'll be using the Jet-Tech fuel cell connections instead of those provided.

Just cut away some of the inlets and move the second tank as back as possible + you need to install a cross bar by the front wing formers this is must don’t fly this jet without it the like to flex and in some cases the former could detach from the fuselage skin this happens before on someone Jets.

'Finished the vertical fin today with internal carbon fiber horn I made, just a piece about 1 1/2" long by about a 1/4" wide. I think it's about 1/8" thick or so. The servo tray I made sits into the fin around 1 1/4". There is a cutout on the vertical spar. I still need to reinforce the thin area that was not cut out. I did get the 2" of throw they recommend for good knife edge performance. I used the Savox SV-1254MG because it is lightweight and has plenty of torque. It has plenty as the servo arm is very short. I'll be using 6.6V LiFe batteries for the receiver and a 9.9V pack for the turbine ECU.
