If you do want to make doubley sure, also if you have any really tough questions on this plane, here's the Horizon site. http://www.horizonhobby.com/
There is a tech support area there, and contact info whereby you can e-mail them direct. I emailed them the same question a few months back. I thought I kept the reply, it's gone though. The site has been a world of info for the H9 products I own(which there really isn't to many for some reason).
Shortman is right on the money here though. There is what they call a QC(QualityControl) sticker located in the bays of the wing.
I'm going with Moki 1.80 in my H9 Edge. Also moving the elevator servos to the rear to compensate for the weight of the engine. And of course a few more trick items to make it nice. It's now probably going to be my winter project though. I've gathered all the stuff already though(half the battle), and need a workbench. I'm still working on last winter's project, so my bench(s) are totally full. I ended up taking that one to the extreme though. Almost done though thank goodness.
