Off-subject, can we reserve this for Mig.15 related build observations please.
But on a related subject: the Mig.15 has a Jets Munts M100XBL

and having seen how fuss-less the Jets Munts family is (quiet starting with no flames or popping) I would recommend them. They also have a much better service organisation than some other turbine manufacturers.
