So with the model assembled and balanced it appears its tail heavy with a standard install. However, it is able to be balanced without nose weight but it required some customized battery mounting solutions. I used a total of 4 batteries in this jet. 2 2s2p 3800 mah TP RX lipos, 1 ECU LiFE or Lipo, 1 retract 2s 2700 lipo. With the bigger and less critical ECU pack mounted in the very nose as shown (no jokes) I was able to achieve balance without nose weight. From here the receiver packs went on some tabbed trays that fit into the F1 former and the rest of the install as much forward as possible but convenient for frequent use.
