Zak's 2.10 is dying. It's that 10% he's feeding it is what's killing it. When he was using the Mejlik 19x8, the vertical sucks, it will stop climbing at 350~400ft. Then he was using a 3W wooden prop 20x8 and is much better. Then I showed him what the Bambula can do with my Edge so he ordered one.

I say Moki 2.10 and a Bambula 20x8 would be more than enough for the DP Extra.
