2. Should the firewall (bulkhead) be set back a little to accomodate a longer saito 56 4-stroke?
Mine is on the board now and I'm sticking with the plans. I have seen several of the ARF versions fly, and everyone knows that kits always fly better than ARF's, so I'm looking forward to finishing it. The model Airplane News article said not to skimp on the engine so I'm using a .52 two stroke. The two ARF's I've seen fly had a .70 four stroke and a hot BB .46 two stroke.
