Hi tclaridge,

Hope I can get out today but the honey do list just got bigger.

I'm running a Magnum 91 4c on 15% nitro.
From what I have read this is more than adequate.
Spinning a 14 / 6 APC prop.
All servos are Futaba 3010's. Overkill? ... but I had them so I used them.
I have a big 2500 / 4.8v stuffed up front on the fire wall on one side of the fuel tank. A counter balance and the cylinder head keep lateral balance.
All control surfaces are set to recommended throws for high rate.
25% - 30% less for low rate.
I have been using 40% expo on all other planes and am comfortable with this so it's programmed in.

I have no clue what the dry weight is. I can get on the scale 15 times and get 15 different readings.

The added weight I used in the cowl is carbide I've hade from back in my tool building days. The stuff is hard and heavy. I do have a little lead flashing in my field box just in case.
