I need help!
I'm setting up a 1/4 scale cub with a DLE-30 gas engine and want to use the best batteries for the job. I will need a set of batteries for my DX7 receiver and one for the Engine ignition syestem. What is the best LiFePo4 or A123 and best place to get them? Please help!!!!

Having done this on my 30cc and 20cc birds I'd go with 1 2300mah A123 with dual leads from the bat. One goes to a switch and then to the receiver. The other goes to a swtich then to a voltage reducing diode extension (see link below) and then to the ignition. No noise, one bat, less weight. I'm running on 2.3 Ghz btw. ... egoryId=10

On my 50cc gasser I'm running a 2300mAH A123 pack for the receiver/servos and a separate 1100mAH a123 pack with a UBEC for the ignition.

Despite the fact that I fly hard and have 50-degree throws on all surfaces, I use about 100mAH per flight from both packs so in theory, I could probably get at least 7-8 flights from the ignition and 12-15 flights from the main pack before recharging.

However, I usually throw things on charge after about 4-5 flights. It only takes about 6-7 minutes and both packs are fully-charged again.
