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.

I am using the 2100 LiFe on the flight pack, 4.8v NiMh on the Robart electric gear To keep isolated. The 4.8 is yielding a scale speed on the gear.

Aloha Gentlemen....
Its been a while since anyone posted here...so I wanted to let you guys in on my next project.

I have been given a seven year old T.F. P-51D. It is well war wary and has had three engines installed....from a O.S. .60, to DLE 20cc gas engine. Never crashed....been flown a lot....and I will be rebuilding the model into a "B." I have the conversion kit...and a rebuilt set of "Lado" retracts. I had the set in this airframe rebuilt and they just came back from France. All I can say is that I love these retracts and the service from Lado is the best.

I did this once before....turned a P-51D to a "B" years ago. That model lasted for six years until I managed to run into one of our wind sock polls at full speed. Not much left...but I used the T.F. conversion kit...and it was an easy conversion. Like my last one...this one will have a Robart retractable tail wheel installed. I never had a one problem with my Robert gear, and it was servo operated.

I have a new cowl...and will be disassembling the model, by removing canopy...and from the instrument panel down to the main middle longitudinal support...you cut aft. Easy....simple and then all you do is install the tail wheel assembly first and working well....for once you cover up the turtle neck...there is not clear access to the tail wheel assembly. I do have the stab to try to remove....but I may just leave it in and remove the control surfaces.

It will be recovered in 332 Squadron colors...like all my P-51's. Red Tails...

A DLE 20 cc RA for power, Airtronics Rx and HD1501 BBMG servo's. This set up in my "D" model....and the rear exhaust 20cc gas engines seem to do the trick and most reliable. Side exhaust engines have issues...but not the rear exhaust engines. I've flown mine for over a year...and not one dead stick.

Soft Landings Always,
Bobby of Maui
