Just received my Regal Eagle in the mail

. Looking over the plans I see that for a Byron fan setup the engine is mounted on its side. All the pics I have seen show the engine mounted upright similar to a tractor. Also, with the Byron fan a "cheater hole" is shown. Any body flying a Regal Eagle built "per plan?" I'm reading and saving all the tips I've read. Any comments will be appreciated. Engine will be an OS 77/Byron fan. Thanks.
