    I don’t know these folks but their videos are always entertaining, really a hoot! This one features a FreeWing A-4, F-86, and either a Futura or Cobra, flying from a hazardous “air field”! Enjoy!

                Picked up a couple batts to try. I’m still a huge fan of the RT’s and the Admirals but just wanted to compare for myself.

                So tomorrow , I’m going to go for 3 flights: RT 5800 35C- 780g, CHL G+ Series 5000 55C-858g and a HRB 6000 50C-863g. Clearly, the RT’s are typically light pound for pound. In this case though I’m comparing a 35C to a 50&55C.

                I will have the timer set for 3 minutes. I’ll look for capacity (volts per cell remaining and mah used) and also performance which is totally subjective.

                The benchmark is the RT 5800 35C-780g. $90.00 ~3.15 min

                The Admiral 5000 50C-732g was fine $109.00 2:45-3:00 min

                My expectation for the HRB is low but I must say, it came nicely packaged and included the Ec5 plug. $86.00

                The CHL is physically the largest at least in width yet has less mah. They do boast a burst rate of 110C. $65.00

                I may have already found the Holey Grail with the RT. But what the heck, I’m open to find any improvement if it exists.

                Hope the day is coming soon on the next leap forward in battery power.

                  First, thanks for all of your great responses. After reading everyone’s ideas, I reviewed the starting point for measuring the CG from the MotionRC “Updates” doc for the A-4. It stated measure 190mm to 195mm from the “flat spot at the base of the cannon fairing”. And there it was: “base”. To me the “base” was where the wing meets the cannon fairing, but after reviewing the picture, the “base” of the cannon fairing is at the leading edge of the cannon fairing – go figure… That fact and the heavy weight of the Turnigy HD battery explains why it was coming out nose heavy. All is well now!

                  Thanks again!

                  Nick

                    Just for the record, I tried my CG at 195mm from the base of the cannon fairing and the maiden was a bit hairy. Got it down safely but my CG is now at 180mm from the same point.

                      Just to be clear, are you measuring from the point shown in the MotionRC updated docs (see attached)?

                        Yes. I also check it wheels down and inverted but I am at 180mm from the base of the canon mount pictured.

                          This is where I run my Admiral 5000 in the A4. Hands off no trim required. Elevator up mix as directed in manual.
                          34 flights so far on the A4. She still looks new. Rugged bird and a lot of fun to fly.

                              Thank you sir! I usually fly in wind with the hump only or just clean. If it's calm I will load her up. But she will slow very fast with the ord. That has bitten me twice resulting in some rough landings and nose gear pin replacements. Hope to get a lot more flights on her.

                              The T-45 accidentally touched down in the tall grass alongside our runway a month or so ago. That cost me $150 in parts. So while I had her down for maintenance, I went ahead and repainted her, The scheme is based on a USNFWS F-16N but adjusted to fit the T-45. It looks like some eastern block thing in the air. Very cool with the LEDs. Graphics by Callie Graphics. The T-45 is my squadron hack. She has 17 flights so far.
                              Another good dependable bird. Also it's an excellent windy day flier. The A-4, not so much.

                                  Does anybody have left over decals for the Navy version? I jacked up the black "300NF" decal that goes on top of the right wing. I also boogerd up the white "300" used on the flaps. I would be willing to pay for them along with shipping. If anyone needs the Marine set of decals let me know, they are yours for the asking. Thanks guys.

                                        I am going to do Marine so I have the Navy decals. You may have them if you wish.
