Michael,
If you're a fan of the MM, then I HIGHLY recommend checking out this thread over at RCGroups:

It's a listing of a bunch of Mods, offered up by the original designer of the Micro Mosquito (Petter) !!
One thing off the bat, you could probably very easily fix your quirk with the tail rotor not spinning up right away...When you dismantle the Tx, you'll notice there's several pot dials that can be adjusted. One of them being for the tail rotor throttle. I'd say try adjusting it so it kicks-in at lower stick push.
Enjoy! I have not doubt these birds are a blast...When you get a good one.
