The engine on the Airfix 72nd Wildcat is very detailed with push rods and wiring visible on the front. Quickboost offers a replacement engine which does give better details on the front cover but you will have to add the push rods and wiring if you want to go that direction. One thing I noticed is the cylinders have a bit of resin connecting them to the rear. While these are not visible through the closed cowling they would be if you want to display an engine change or just have the cowling removed. They look a little awkward to remove but anyone with experience working with resin replacement parts should have no trouble. One nice addition is the rear of the engine is included with this set. That will add additional detail when looking in the landing gear well area.
I did a quick check and the engine fits inside the cowling with no modifications needed. >
Simple instructions are provided to help position the parts.
Thanks to Aires and IPMS/USA for the review kit.
