The plane actually balanced very well with no extra weight needed, I am using a JR extra battery pack which is a little heavier but was able to use it to balance the plane at about 5 inches back. I looked again today for a 13-5 with no luck, but did pick up a 13-4W and will try both it and the 13-4 this weekend. I also picked up a 14-4 and may give it a shot to see how the engine reacts with it. If need be I will order a couple 13-5's to try out next week.


As a side note: This will be the first flight of this engine since I discovered (with the help of the RC Universe forum, extra thanks to William) the cam gear was 1 tooth off from the factory, needless to say I am excited to see how much better if flies with full power, I do hope I did not hurt anything flying it with the timing off. I wrongly assumed things would pick up after a little more break in.
