Good Morning All;

  Have a Brodak Shark 402 on the building board.  42" span, 402 sq. in.  Designed/recommended for a .25 - .35, but I am going electric.

  Originally I envisioned using an eFlite Power 15 (950 KV) and 4S pack (~2700 mAH), but lately I've been thinking a Power 10 (1100 KV) and 3S may be more appropriate.   

  Looking at the "List Your Setup", it appears similar sized planes (Flite Streak, Magician) are using motors comparable to both of my options/choices.  Am I over-thinking this and should keep to my original plan, or is one course of action markedly preferred over the other?

Thanks in advance,
Dave

Hi David,
 When we were flying flight streaks we were using Power 10 sized motors of various brands all in the 900KV range on 4s2200mah lipos. For props we used a 9x6 APC pusher. These worked very well on 57-60 feet of lines. If you want to use 3 cell pack any motor in the same size range but around 1200 kv should do the trick. You will need  3 cell packs at around 3000 mah maybe a bit less.
