Three more flights today on the P-51 today.  I think they were number 10-12 on this bird.  She flies well with adequate power from the DA-50 and with full flaps the landings are getting to be smoother all the time.  No appreciable bounces today and 2 landings that were totally greased in.  I may have to start saving to modify the retracts to electric power and consider installing them if I keep this up!  The Top Flite is a really nice flying model.  Once you get the flaps dialed in with a little up elevator mix on deployment it isn’t too bad to land.

On the skydiver front, George had a bad day.  After a successful early jump, the next two were ugly.  First, the release mechanism didn’t and he stayed firmly attached and then on the next attempt he did a “hanger” and simply drug along behind all tangled up and just to add injury to insult his arm busted off when I landed… 🙁

He has already been repaired and is ready for the next attempt.  Also had a scare with misplacing his “static line” that attaches to the plane and allows his parachute to open upon his exiting the airplane.  I eventually found it but it has inspired me to build a second one as a spare.  If I can find a little cheap metal spring hook I think I will be in business.  The rest is easy… just a release pin in the middle and small patch of hook and loop on the end and I’m in business.

Put up 3 more flights today… about 7 minutes each.  Total battery usage was around 480mah so the average looks like ~25mah per minute of flight.  Even less than last time but probably less “on-time” between flights etc… so more typical of actual flight times.

Finally got my flap mix to elevator about right I think and all three landings were good.  1  bounce or less and no really anxious moments.  Just greased’em in!  One flight I got a reported 96mph so I think maybe 100 is going to be the top speed if I get in a nice long full throttle dive unless I make some changes.  I can’t complain about that.  It seems reasonable enough.  I’m not seeing any excessive temps… around 230 I think is about normal peak which seems on the cool side so I’m not going to complain.  Flight pack voltage is very steady with the two A123 packs supplying a nice and fairly steady 6.5 or so volts if I recall correctly and the IBEC is locked in at 5.2V.

Did some nice, slightly high, photo pass/knife edge passes and some sub 30 foot high speed passes along with a few Immelmans, Split-S, loops and plenty of rolls and combinations.  Stall turns are fairly easy and I am having few problems with orientation.  All in all, its shaping up nicely.

After the 3rd flight I sat and made a few adjustments in the radio.  As is my usual method, I started with dual or triple rates configured for each of the main flight surfaces and once I narrow down throws and expo settings I like the rates go away and all are set to the same settings so there is no chance of problems due to improper switch settings.  Ailerons are pretty much dialed in and rudder is comfortable though I may need to fine tune a bit.  Elevator is nice for landing but the plane can snap if I pull too hard.

I’ll have to decide if a bit less elevator is still good enough for landing but other than that I’m getting pretty comfortable with the Red Tail.

My Red tail P-51 Mustang started out life in late 2004 as a standard Top Flite Giant Scale P51 D purchased by Mr. Tim Mills.  Tim bought pretty much everything needed to get this bird flying during a 1 week period.  Everything from engine to scale exhaust, servos and retracts, as well as the ARF itself and more.  When it arrived he started to convert it to a B model by stripping the body and adding the turtle deck aft of the cockpit using a Top Flite conversion kit.  The structure got finished and the body glassed and prepped for painting.  Tim wanted his P51 to “represent” the Tuskegee airman as he was one of the few black men involved in the RC flying hobby… at least in the greater Indianapolis area.  Tim had done some reading on the subject and found that the Tuskegee had first been issued B model mustangs so he had to convert his.

For some reason, at that point the project stalled.  I don’t know exactly why it stalled.  Likely Tim got involved helping out friends who needed some assistance with anything from Airplane setup to health issues.  Tim was the guy everyone called when they needed a ride somewhere, a helping hand with a home project, advice on flying and setting up RC planes and just about anything and everything else.  Tim had built and driven drag bikes as well as running a race circuit earlier in life, been an owner/driver of a semi-truck and maintained and rented out properties.  He was a Jack-of-all-trades and always generous with his time.  He was also a big talker and loved just hanging out with the guys at the flying field.  He helped me learn the basics of IMAC style flying and we traveled to a few events together in the last 4 or 5 years of his life.  With Tim in attendance, it was always a good time for me.  He also spent a good amount of time working on RC projects with me, both his and mine, out in my work shop.  I learned a lot during those sessions and like to think I taught him one or two things as well.

In any case, somehow the Mustang languished for almost 7 years and everyone had a good time asking Tim when the Red tail was going to be ready to fly.  This continued until Tim passed away in February, 2011.  I had personally benefited from flying and traveling and just becoming friends with Tim and I wanted to finish the Mustang in a way that Tim would have enjoyed so I contacted his nephew and bought as many of the parts Tim had acquired for the Red tail as I could.  I hadn’t planned on this project but I scraped up as much as I could and bought the Airplane, motor and Keleo scale exhaust at a very reasonable price.

By spring of 2012 I had the plane ready to fly and besides adding the distinctive red tail and other markings unique to the Tuskegee airmen, I added a few special touches toward making it a bit more of a memorial to Tim.  These include a pilot figure (black of course) who is clothed in appropriate attire and can salute on command from the transmitter; graphics on the cowl proclaiming the airplane name to be “Drag Racer II”; and adding the pilot name to the side of the cockpit area.  The call sign “Smooth” was chosen because not only did Tim enjoy Jazz music but many folks described his flying style with that word.  Here’s a picture of the cockpit area.

There are a few other nice touches I’ve added to the bird to make it unique but I’ll save those for some future posts.  I’m still working on learning to fly this plane sufficiently well to be comfortable and trying to keep it looking good in the process.  I’d hate to lose it in an accident and that is the reason it hasn’t flown much yet.  Recently though I’ve decided I just can’t let it become a hangar queen as I can easily imagine Tim’s reaction to that.  I can hear his voice in my head right now saying “Just fly it, man!”.

As I do just that, I’ll post some more information and pictures on the Red tail.  I hope Tim would approve.
