The fact it is usable in the MA is not right. Totally wrong place for it
Some history on the relevance of the RV-8 in-game.
Back in the day, there were several AH player conventions, mostly held near Grapevine, TX (Close to HTC HQ) After the traditional Saturday night banquet, an "Evil Con Mission" took place. Those attending were provided a rather special weaponized object that flew

Given that HiTech had recently acquired an RV-8, that was the Evil Con Mission aircraft one year. except this RV-8 had limitless Vulcan cannons

About 80 of these were let loose in the MA that night. Oh the humanity!(and endless tears & whines)
The following day, Dale explained the RV-8 was used to model certain flight characteristics in-game. A few of the Con attendees asked if the RV-8 could be enabled upon request (sans Vulcan cannons) and the wish was granted.
And there you have it.
