Henlo guysh.
I had been working for this le thing for almost a yeaeaear and a few mooonths and I was very bu$y with other wOrk. I luv this engine because it's so unique and as well for it "eerrr-Buzz" engine sound.
Anyways, this is it:

Rolls Royce RB.183 Tay 620R-15 Turbofan

It's a tRolls Royce but that you can't drive around streets, instead it will power you and take you to the skies.

This is a RR RB.183 Turbofan engine (Tay 620R), which was designed and built for both Fokker 100 and 70 in the late 80s. other variant is 650, which was designed for Gulfstream IV and F100 (as optional engine), hence the very similar to 620.15 in terms of exterior design.

Features

•(Key Feature) Working mechanical parts
like functional custom blades (fan) and bucket thrust reverses and etc...

•Distinctive design and pretty well detailed

•Detailed internal section and Exhaust mixture part

•Built based on actual weight

•Easy Attachable

•Configurable; That is, you can change or modify it to 650.15 for the G-IV or any compatible aircraft with minor changes in the end part of the engine or in the power of the engines or rotators.

This is one of the most detailed and only Tay 620 (from RB.183 family engine) in sp.
I worked really hard to make it, it's just part of what I'm working on...
