John, I really like the battery box idea. Noet time I set up the old bipe I will give that a try. My pack was inside the plane mounted to the fire wall but that could be a big weight saver. Next engine I try in the Boeing will be an RCS 1.40 so I could set up the flight pack on one side and the ignition pack on the other. Thanks for the photos.
Thanks GB, That battery up front is a simple and reliable solution for certain problamatical airplanes that I have used since the seventys. These three pictured are just my current ships using it with exception of the big Yak as thats just a weight box.
Interestingly enough I first tried it with one of my first electric over the wire throttle systems on a controlline airplane long ago in LA and there has been an occassional RC ship ever since that the forward battery has proved very usefull on.
It can make a hugh diff on many snub nose airplanes and your lovely F4B is a prime example a ship I would have used the nose battery from the start.
Folks have been telling me for years that it won,t work because of heat and vibration, well I proved them wrong. I beleve depending on how you build the box that there is no additional vibration and that the batterys run cooler than in more common heavily insulated locations.
I always put the battery where it needs to be. Heck I have one airplane with two .25's on it that the battery is located all the way in the rear under the leading edge of the stabilizer, and when I tow it up as a glider droping the engines off the battery is relocated to a spot all the way in the tippy tip of the nose and plugged into at waiting Y corded lead to the Rx.
