Gents-flew my hopped -up p-47 this am. I was flying 4 blade e-flite prop ( as seen in the pics of previous post ) on 3 cell 2200mah 30c with 30amp esc . This mornings flghts were on 4 cell 2200mah 30c with 40amp esc. Overall, i would estimate that at half throttle i'm 25% faster-than i was at full throttle with previous set -up. My top end has seen an improvement of about 40% . Very happy with this simple hop-up and it didn't cost me a thing as i already had the batts and speedy ( nice!!
) As a bonus only needed 1 click of elevator-up trim ( nice again!!
