This aircraft may have been used with a Monsoon beam (?), which allowed two R-3S rockets to be carried under each wing. The parts needed for the Monsoon beam are on the "H" frame, but are described as "unused parts."
The inlet cone traditionally does not fit in the ring. After a while, I thought about filing out the notches - bingo! Why didn't Eduard do it as standard?
Sorry, but I have to remove 2K gloss varnish and paint model again or... find a new kit. The varnish layers are unacceptably thick and the model loses detail 🙁
