I lost 2 planes with nothing but the best   PTS P51 with 821 digitals,AR7000 receiver, 2300 mah 6 volt, new Evo 60nx new everything that made it through 1.5 flights.  I must have had $600.00 in her.  Now she's in a Glad bag.
New Revolver 40/60 sized with a new 821 digitals, AR6200 new reciever, spiraled into a nose dive hitting paved street losing engine and everything.
I can't say good money guarantees good flight.  After these recent losses, I'd be willing to spend less and lose less.
