Hello, it’s been a long time I didn’t come here!
…it’s a WIP that I plan to finish soon but I’m never happy with little details of the result, hope it won’t take me months to finish!

WOW! How did you made the fins of the engine? Are they separate or one mesh? There is one problem, though. The speedometer is sticking to the gas tank.
thanks, yes, the fins are a stack of meshes and for the speedo, it doesn’t touch the tank but you’re right, still some changes to make! ^^
