If it a shorter nosed bipe like a Sopwith Camel then that could be accurate. As far as, is that too much, what is the upper weight limit on the kit? If you are too much past that then you may want to consider moving some gear. Putting the battery in the cowl works well. Just build a fuel proof box to put it in, preferably above the engine or opposite the exhaust.
Movine gear forward helps but like in my case, there wasn't anything else to move. I made my own cowl and it is really thick glass and very heavy. That helped but wasn't the total cure. The three pounds of lead had to get set into the cowl qith epoxy. Last year I was looking at that Boeing and decided I could put a 40cc gas engine up front and remove all the lead. That didn't work out too well and I had to still add lead. I went from an OS 1.20 pumper to a Brison 2.4. I would have thought the added power would make a better flying plane too, nope, it was still a slug.
Hind site being 20/20 today I would have built the plane with the nose of the fuse extended, a lot!! Then I would assemble the plane complete without the covering and have the engine mounted to the fire wall and then set the plane up on the CG machine. Tack the engine/fire wall to the fuse and keep moving it forward until I got the CG. Mount the fire wall in that area, cut the fuse at the fire wall. Not 100% scale but other then myself who would notice. The nose moment would be a few inches longer then it should be.
There are things you can work around. That plane would be better with ailerons top and bottom too. The full scale had small ones on the top wing anyhow so it isn't scale anyway.
It was a fun build, plans by John Tanzer, at 12 pounds it would be a killer machine!!
