didnt weigh the motor beams, there only small though, enforcements (firewall and doubler?) weight 10 grams more than the electric motor mount i cut off. flight pack is a sanyo 4.8 volt nicd 1500 mah, yeh i know.. bit much, but i love having not to charge during the day , point being why i decided to go glow this time, sick of waiting an hour for batteries to charge and it becomes too expense to keep buying excess back up batteries. so i dont think it will come in too much different from the power 10 set-up i listed above...
