Yeah, I'm using the same speed controls.
I'm not noticing any problems on the bench, as I try to estimate full power flight times. If I remember correctly, you have a 3 cell and I'm using a 2 cell tanic.
Don't know if that makes a difference. Was going to fly last Saturday but had a soccer player infestation at my primary field. Will try to fly the Viking this Saturday. Definitely more power and for sure much lighter than the stock set up. At the moment I feel much more comfortable with this set up.
