I should clarify- i didn't rip out the entire nacelles. I did have to rip out the entire nacelle covers, which I had secured in place pretty good. I was hoping to be able to turn the mounts 180 degree by only taking the small engine covers off, but I could not. As a result, i had to pull the entire fiberglass cowl covers off which damaged them in the process. Anyways, AK models was kind enough to ship me out the replacement parts so I should hopefully be able to try this out again.

kmot, yes I could have tried the regulators, but there is limited room in the nacelles anyways and I wasn't sure they would fit. Not to mention that a pair of regulators would be much more money than I want to spend. Those regulators would have been more money than I paid for these engines brand new.
