My balancing concern: I would have to embed my 5-cell battery as far aft as possible inside the fuselage and also add 3 or more ounces somewhere on or near the tail. It may be normal/correct but I've not had that experience with any other ARF. Therefore, I would love to talk to someone that has successfully flown that airplane with a .91 or .95 2- stroke engine to confirm. Tnx.
