Hi all.
I've been struggling with the engine connected to the monocoque and bottom plate of of the Ferrari.
This is were Protar & Revell give you a hard time. Following the manual you would probably break a lot of parts from the rear suspension.
I took all fragile parts of and dry fitted the engine. 
Then another problem shows up. How to get the triangular shapes back in position with out ruining the bottom plate?
I made connectors from small metal tubing which are pre-mounted.
Size and length will be easy to measure this way. Even thinking of reproducing them in full metal tubing.
Other thing I mentioned before was the aerodynamic part at the front of the bodywork. There are no covers to the underside of the front suspension. Research pays off and I found the way to do it. Also found the right material to make them. I work in recycling nowadays, so I found some coated copperplate. Very thin and perfect to bend. The best part is that the coating can be glued with CA. 
Next I will have to decide on whether the Ferrari gets a front wing. 
I prefer the version without, but detailing a front wing to make it adjustable looks also very cool to me.
