RE: cost per flight hour vs. glow
I gave up on Lipos for any big models -too much $$ for too little fun
My next electric "pattern plane " scoff if you will -is another of my old Zlins - rather small and too scale etc etc.. but these flew well and I can do it with 6 A123 cells and a 60 size EFlite - the pack cost ? 66 bucks
how many needed?
one. just charge it while you relax a little .no heating no waiting etc- Iam flying two smaller models -getting the feel for what is really good and what is not -so far it is all positive.
my 2m new plane is slowly coming along -may end up electric instead of the ZDZ40F3A --which does work extemely well -
