RE: Venus II - Adding an adjustable stab worth the effort?
Teo,
If 1200 watts is satisfactory .... then yes, you can do that fine. Personally, I would use a pair of those 5S 3200's and get about 1600 watts at 45 amps.
It is all a matter of personal preference. I'm sure it will fly just fine on 1200 watts. Good luck .... and please keep us posted on your results.
