Hey Don:

I think the H9 cap would be a very good combo. Had one with the old 3w 80 and it easily had unlimited vertical. The new 85 has more power and weighs over 1lb less. A friend I fly with also has the cap and a DA 100 with over 300 flights. It is ballistic and has way more power than he needs. The cap is very good for 3D and IMAC type flying.
