Camel vs. DrVIICamel - Flat turn most effective form of defence. Also best form of attack. Not point trying to fight the D7 in the vertical, the camel will mush over and die very quickly, if not auger straight out. Flat scissors will not help if the D7 is behind the camel, it will only give the D7 more chances to fire. If you can avoid the first attack (probably from above) then the D7 will have to work very hard not to get into a flat turn fight, which it will lose. Using correct methods for defending BnZ passes and chasing the D7 up briefly should provide the camel with a decent gun solution and quickly drain away any E advantage the D7 has
D7 - Keep the Camel below you and you may stand a chance. Best method is smooth looping attacks. Standard BnZ tactics will not work. Make the first attack count and never try and turn flat. If you fluff up the first attack, turn away from the target as soon as possible and try to regain an altitude advantage without getting shot. It is possible to defeat a camel in the vertical but do not under any circumstances attempt to follow it round a flat turn.
Camel vs. DrIQuite an even match. What the camel lacks in turning circle it makes up for in vertical performance. The DrI gets very mushy in the vert. This match is always going to be down to possition and pilot skill. The camel should try to maintain its speed and use the engine to reverse direction quickly in the vert. The DrI should flat turn as hard as possible untill the camel is stuck on the deck and then keep it up untill it gains the camel's tail, which should take not much longer than 4-5 full revolutions.
DrI vs. DrVIISame as D7 vs Camel, although even more importance on not turning flat with the DrI, and slighty more chance to use vertical moves to gain a firing solution.
Just my first thoughts so far, maybe not too great but there it is
