The plane isn't any good. All of the US planes carry far more bombs. All of the Allied plane can carry rockets. The 110 is made out of some wierd substance, like glass or maybe hardened paper. It got 5,402 kills last tour, compared to 7,267 for the 190A5 (ENY 36), 7,156 for the 190a8 (ENY 35), 13,119 for the P-38 (ENY 22), 7,556 for the P-47D-30 (ENY 30), 19,935 for the Typhoon (ENY 24). All of the above will handily kick the toejam out of the 110G2 in a fight. The only ENY value that makes LESS sense is the 190F8, which had a whopping 928 kills last tour. It has an ENY value of 25.
Lower the ENY value on the 110G2 and 190F8 to make them worth flying, or give them some rockets so people don't have to try to use the worthless cannons on GVs once they run out of all 1 or 2 of the useful bombs.
