very impressive! and no problem. it seems yours is a bigger version than mine. Actually, the SR-71 I posted was my 4th version. the 1st version I did was way too large so I decided to downsize it because of the issues with the controls during flight and the really bad wobble through the aircraft. I realized that a smaller version was easier to control and had more speed. mine can even reach speeds of around 500 m/s inside the atmosphere. lol you should've seen how much struts I used under the aircraft. it was crazy!
