My GP Extra now weighs just over 24 pounds. I no longer have a TME smoke system (just didn't use it much) and I saved 9 ounces replacing a pair of 1500ma nicad receiver batteries with a single 2700ma niMH battery with twin leads for the dual receivers. Your 3w 78 twin weighs about a half pound more than my BME 102 twin. Mine torque rolls at maybe 1/3 throttle, so you'll have enough power to torque roll, but you won't have much left for a vertical pull out. Other manuevers won't suffer though.
If you already have the 3W 78, put her in there, it'll fly well. Having more power DOES make a difference, though. It allows you to fly slower and more realistically, since you don't need to build up momentum to do vertical stuff, rather you can power through the up stuff.
