Fire "Spotter" over Helderberg Area, Cape ?

[Gunship]

The whole of yesterday afternoon a Orange coloured "spotter" plane flew over our area.

Big radial in the front and very slow flying leaving a trail of smoke himself (which makes me believe it is Russian )

Anybody got more info on the make / model please ?

Cheers,

Gunsss

PS: Thanks for the fire-fighters for all their hard work (again)
