Mikoyan/Gurevich I-270

Created by the OKB as the Zh to meet a 1945 requirement for a rocket-propelled target defence fighter, the I-270 was based broadly on the Messerschmitt Me 263, but was of a less radical configuration, featuring a straight wing and conventional horizontal tail. Adopting an ejection seat for the first time in a Soviet fighter and having a wing of near-laminar flow profile, the first of two prototypes was towed into the air behind a Tu-2 - with ballast replacing the rocket motor - in December 1946. Only the second prototype was to be fitted with the rocket motor. This, the RD-2M-3V developed by L Dushkin and V Glushko, was a bi-propellant dual-chamber unit affording a total thrust of 1450kg of which the cruise chamber contributed 400kg. The cabin was pressurised and proposed armament comprised two 23mm cannon and eight RS-82 rockets. The second prototype flew under power early in 1947, but was written off as a result of a landing crash while being flown by an NII VVS pilot. Shortly afterwards, the first prototype was damaged in a belly landing and was not repaired.

How much ammo did it have?

To say that this is a 100% of the Me-263 makes me think you're blind. They are similar looking ..heck yeah. But 100%? Not even if you squint.

I'm working on a kit of the I-270. I have two questions: (1) what color would the seat belts have been; and (2) did the radio antenna post run through the rear of the canopy glass or was it set to the side of the rear canopy (like a Yak 15 and other aircraft of that era)?
Thank you!

I'm really surprised that after all these years, no one has responded to your question. The answer to your question is that the antenna post, as shown in the 3D images, was mounted to the rear section of the canopy.
