RE: Reason for not upgrading to 2.4
I was the one that responded. Let me explain why:
I converted a 6 year old Lazy Ace to electric power. I use 9 A123 cells on a Scorpion 4025 motor. The ESC is a Chinese knockoff that I bought at an expo for $35.
The LA flies about 6 minutes and I can charge in 10.
I used an Xtreme 2.4 system in my Futaba 9C.
I flew the LA for about 50 flights and switched it back to 72 using a PCM receiver while I sent my 2.4 stuff back for update.
On the 72mhz flight the receiver went into failsafe at about 100 yards and the airplane crashed. It seems the 72 PCM receiver was wiped out by the noise generated by the KO BEC. It hadn't bothered the 2.4 system.
