Anthony,

I don't have the tangent but I do have the Wattage Sukhoi which is around the same wingspan and uses the same 370 geared motor as the Tangent.

I fly my Sukhoi is an area about the size of a soccer field without much problem.

If the Tangent is the same size using the same power system it should'nt be much faster than my Sukhoi if any.

I fly using the Wattage 8/800 nimh pack and It will loop from level flight and inverted flight is good. Not enough power for sustained vertical or knife edge manuevers with the stock system but then again, more power = more $
