I found this review from Floyd Werner Jr. and it look reeeeally nice to me. its in 1/32 scale and the company makes 1/32-172 scale very very detailed engines. the thing is, is that it burns a hole in your pocket book ;), but hey what doesnt burn a hole in your pocket book that deals with aviation, or modeling!?!?!

[#oops] I did not see this thread before I posted to your R-3350 thread[;)]
I a Vector engine that will go into a Helldiver in 1/48 and they are just beautiful. But as you said… not cheap.
Oh boy that looks yummy! Yeah I was thinking of either displaying the engine on a stand or in the plane but the Fury im doing need alot of mods to it and I am seriously thinking of displaying the engine ona stand instead. But Theres no R-3350 out in 1/32 so Im gonna have to go with the R-2800 there a bit similar I think. The looks anyways
I like the splines cut into the propeller shaft. That is a really nice touch that is commonly overlooked.
Great detail .
