I use a Venom 6v. I've never ran out of power so I don't know how many cycles it gives.

Not 100% sure but I do believe they are the 85* ones, and I use a 2100 mah LiFe to power the plane which has plenty of juice to drive the radio and the gear. Since I haven't flown more than 2 times at any one day, I don't know the flight time for the retracts.

I was thinking of using a 4.8v 2000 mah Nimh. Should be good enough for 2 or 3 flights. Can't wait to get this plane in the air.

Double check the retracts, they may not work well with low voltage, you would be better off with a 6.0 2000 mah pack, provided your servos can handle 6 volts.

Oh, I was thinking I had to use a separate batt for the retracts. I'll definitely use a 6v 2000 mah batt for the servos. If I can use only 1 batt for servos and retracts that would save me some weight.

Thats what I did, but I don't fly as long as others do, so depends on how many flights you are looking to do.

I regularly fly mine 3-4 flights of about 10 min each and have done 5 flights in a day. Mine has standard servos (Futaba 3003), Hobby King retracts (large if my memory is correct) and a 4.8 volt 2000 mAh NiMH battery. No problem, my battery typcially has well over %50 left when I charge. Occasionally I cycle the batteries and then recharge. This too shows that I have plenty of capacity left.

5 flights in a day would be great!! Those of you who are using a dle 20, where are you placing your batts? (Servo and ignition) I'm looking to mount my ignition on the firewall somewhere.

Hay Drube,
I use a NoBs 3000 mha. nickel battery on my T.F. P-51. Go to post 3203 in this thread to see that is placed on top of the wing, just forward of the trailing edge of the wing. With a DLE 20RA...it was the best place for my balance point of 5-3/8", I use electric retracts (Lado's) and all HD 1501 BBMG servo's. I needed weight aft to balance the model so I went with a larger battery to do the honors. It worked out great.

P.S. I would up load pictures, but don't have a clue now how to do this on RCU.

Soft Landings Always,
Bobby of Maui

Thanks Bob, those pics are great!! I like how you have your tank mounted. I didn't see the aft mounted batt though. I'll figure that part out when I balance.
Thanks again (:

I put my battery in the fuselage just behind the trailing edge. When that was not enough I mixed some lead shot with epoxy resin and poured it into the area under the tail wheel access hatch. I also mounted my fuel tank on a platform over the CG.
