Finally was able to get some flying in and try the 4S with the Turnigy SK 35-42 1000kv motor and a couple props, 11 x 6 and 11 x 9 two bladers. So far, I like the Nano-Tech 3300mah 4S 35C on the 11 x 9. Was getting quite a bit of yaw wobble on the 11 x 6. There is a very small amount of slack over the shaft and I also haven't balanced either one of these yet so could be from a combo of both. Let me know whatchya think when viewing the vid.

There are some out-of-frame shots b/c I'm still messing with the angle on the FlyCamOne HD clipped to my hat and I should have that dialed in next time I go out.

Here are some stats on the peak readings:

Prop: 11 x 8.5 3-blade
Thunder Power 2250mah 3S 30C - 12.6 v, 37a, 372.8w
Turnigy Nano-Tech 2650mah 4S 35C - 16.83v, 63a, 904.8w

Prop: TP 11 x 6 2-blade
Thunder Power 2250mah 3S 30C - 12.54v, 26.2a, 278.7w
Turnigy Nano-Tech 2650mah 4S 35C - 16.83v, 46.6a, 703.6w

Prop: Master Airscrew 11 x 9 2-blade
Thunder Power 2250mah 3S 30C - 12.6 v, 29.6a, 307.6w
Turnigy Nano-Tech 2650mah 4S 35C - 16.83v, 51.6a, 761.2w

Prop: TP 11 x 6 2-blade
Turnigy Nano-Tech 2650mah 4S 35C
Corsair 4S 11x6.MOV (6 min 19 sec)

Well, finally getting back into my workshop and making things happen with my Corsair again. A while ago I bought a new fuselage and wing and have slowly been rebuilding. Unfortunately, with all other things going on I only have been getting about 1 - 2 hours/week to spend on hobby-time. I hope to make more headway this weekend. Although, we just got our house under contract yesterday so it's looking like my hobby-time will suffer longer until we get into a new house and settled. Stupid real-life stuff gettin in the way again!!!

Anyway, b/c I like speed I plan on putting this plane through it's paces with a Turnigy SK 35-42 1000kv motor and various props and either 3 or 4 s batteries. I have a Exceed RC 60A ESC and using HXT 900s for the ailerons, Hextronic MG-14 for the elevator and Corona 928BB for the rudder/tailwheel.

To accomodate the power, I have reinforced the fuselage with two strips of carbon fiber along each side of the fuse from the very front to about 4" behind the elevator servo (see photos below).

Also, I am resurrecting the elevator I had on the Version I Corsair that was already reinforced with CF and re-hinged. I noticed that when pushing/pulling on the elevator horn, there was quite a noticeable difference in travel from left and right sides due to the weakening of the small section in the middle. I corrected this by adding a small strip of CF along the the leading edge of the elevator control surface. Applied 5 min epoxy and a bit...Continue Reading

Well, I never thought I'd post a post like this one, but on Saturday, March 5, 2011, the PKZ F4U Corsair (1) and the Airfield P 51 Mustang (1) spiraled to their deaths in less than an hour of each other. Pilot was not injured!

I have now coined those lovely birds as Corsair 1 and Mustang 1 b/c they will be replaced with Corsair 2 and Mustang 2. Interesting enough, I wasn't too depressed about this. I think when flying RC planes you have to expect something like this sooner or later, although, I'm bummed I lost two planes in one day...

I think my eagerness to re-maiden the P 51 got the better of me. I went to a temporary flying field that some fellow fliers had found while the city is building a new model port. There was a gentle breeze at my house when I left around 10:30 a.m.. On my way to the site, I noticed all American flags were perfectly horizontal, showing all stripes and stars, from a strong south wind. I had four planes with me and thought, well, I'll at least fly my trusty Corsair first and see how the winds were aloft.

The wind was anywhere from 15-20 mph with turbulent gusts exceeding 25 mph. It was one of those days were you stand there outside your car and contemplate even taking the planes out of the car. Well, since I haven't flown much in the last few months and I am finally walking decent after surgery in Dec., I decided to take the Corsair and P 51 out. I have flown both planes in similar wind conditions before although it was the...Continue Reading

Here is a video review of all the modifications I've completed on the Airfield P 51. I was in a bit of a rush when I did the review and I forgot to mention several things, but I tried to capture that stuff in the annotations.

After numerous motor ceasings, I finally JB welded the end cap on the Turnigy SK 50-55 580 motor and was able to put the plane together and balance it. She's ready for the maiden! Just need some good weather, a few free hours, and a good place to fly... I'm also waiting for my replacement FLYCAM HD camera to arrive as I would really like to film the belated maiden so we'll see how long I can hold out. I've called Hobby Lobby 3x with no response

Anyway, here is the photo shoot......Continue Reading

I have finally installed the Turnigy SK 50-55 580kv motor into this bird. I was hoping to dump in the yet-to-be-released Custom RC Parts adjustable motor mount that is supposed to fit this plane but mid-February was just too far away. I went ahead and modified the stock motor mount to allow the new motor to sit in flush with the cowling. At first, I was going to do the JBC-approved PVC method but upon further inspection of my firewall plate (V5), I didn't think that was a good idea b/c then I would be missing the stock screw holes that are thicker and would be screwing into thin (~1/8" thick at best) plastic - see first photo below. I didn't think this would be safe or a good idea considering the weight and power of this motor. So,... I took a look at XXXcellarator's motor mount mod and basically followed that same concept. NOTE: I mounted the motor mount legs to the pilot's left of the mount and the screw holes for the motor itself to the pilot's right. This allowed for a perfect alignment left-to-right. Thanks to all those that have made or modified the motor mounts for this plane and posting their findings/illustrations on the FMS P 51 thread. I take a bit from here and a bit from there...

I plan on testing several different prop configurations and have all the props and spinners reamed out to 8mm for a snug fit. Had to sand the protruding plastic off the rear of the stock spinners to get them to sit flush and rotate w/o wobbling.

Anyway,...Continue Reading

Here's a couple photos of the re-hinge modification. I basically followed Wind_of_Change's video tutorial on the hinges (Thanks Todd!). A little dab of foam safe CA will do ya!

Used these for the ailerons, elevator, and rudder:

and these for the flaps:

I have finished the steerable/retractable tail wheel mod on the P 51. Thanks to All American and Sandancer for my reference points and tips. I am quite pleased with the turn out. I ended up going with the pull-pull method so as to run one servo from the servo tray to operate both the steering and rudder. This also eliminates the need to have an additional servo at the rear of the plane, more weight/tail heavy...

Materials used:
  • HK 312 for retract (drill swivel arm hole out to 3/32 to accommodate the 8-32 hex standoff screw along with some removable threadlock!)
  • Hextronik MG-14 14g servo for steering and rudder control (not yet installed)
  • Pull-pull system purchased from LHS (includes cables, micro EZ connectors)
  • 3/8" foam for cable headers
  • 1/4" plywood for rails (these are 1/2" wide x 3/4" tall x a bit longer length than 312 mounting plate plus lowest rail cut to longer length for added reinforcement)
  • .125 round Carbon Fiber spars for added reinforcement
  • HiTEC servo Tiller Horn
  • 8-32x1/4" Hex standoff screw (male on one end/female on the other)
  • 8-32x1" button head allen screw
  • Misc 8-32 nuts, washers, and internal star locking washers
  • .064" thick stock aluminum for wheel caster (used metal bender pliers and sheet metal sheers to cut, along with files to shape evenly on all sides)
  • 3mmx20mm shoulder screw for axle
  • Stock nylon wheel nut (drilled out to fit axle thread)
  • Great Planes 1 1/4" tail wheel
  • Thin nylon cables for

Here's the progress-to-date of my mods on the P 51... PART III

Main HK 514 Retract Mounts

I have the main retracts complete! I am happy with the strength and the fwd rake I was able to obtain while keeping the struts, wheels, and skirts (at least the front edge) quite flush with the profile of the wing. I will "generally" explain what I did here and you may also follow along with photos and their descriptions posted below. If you have any questions or comments, please reply!

I used 1/4" plywood and 1/8" plywood from the LHS for the rails and mounting brackets. The rails in the back are 13/16" high using three 1/4" and one 1/8" ply glued together (with a bit of sanding down). The rails for the front are 3/8" high using one 1/4" and one 1/8" ply glued together. They are both 3" wide and 7/16" thick to accommodate the Hobby King 514 retracts. I then measured in the 1/4" thick mounting bracket with the retract inserted by using 1/4" spacers and moving them around to make sure I was achieving enough forward rake. I had to use the Dremel to carve out the rear and front wooden rails in order to angle the 514s forward. Also did a bit of sanding on the bottoms of the rails to ensure the LGs would nest properly in the wheel bays. I preferred to cut out the wood as opposed to carving into the foam so as to get a more accurate and snug fit for the 514s. I also had to cut down into the foam wing...Continue Reading

A bit about my Airfield P 51D Mustang 1450mm...

I convinced my wife to get this plane for me for my birthday in November 2010. Well, actually, I bought it in October and she gave me the money for it in November. Clever, I know - but I'm sure most that would read this and have a girlfriend/wife have done the same thing.

I bought the ARF version for $209 from Nitroplanes. After receiving the plane and reading a whole lot about this plane on, I realized that I should've just bought the airframe only version and put my own electronics in it.

QA/QC of the packaging leaves little to be desired by Nitroplanes. Their instructions suck. Wing was bent upon packaging but straightened it out as best I could. Also, the motor mount was installed upsidedown so I had to adjust that. There were few other things I wasn't impressed about with the quality of "glue and press" with the plane but I have since fixed most of the problems.

I am doing about 80% of the mods to this plane that I have learned from the "Giant FMS EPO P-51.....Nice" thread I mentioned above. Lot's of experienced guys on there and I have learned a lot by perusing that thread.

First I will list my electronics and power system upgrades:

This was the first plane I bought after a 20 year hiatus from RC flying. I bought this in April 2010 and the following are some videos and modifications I've done to it.

The following lists some of the upgrades/mods:
  • Eflite Power 10 motor
  • Eflite 40A ESC
  • Eflite prop adapter
  • MAS 11x8 two blade prop
  • Dave Brown Lite Flite 2 1/4" foam wheels
  • Sullivan 3/4" rubber tail wheel
  • Misc Carbon Fiber and packaging tape reinforcement
  • Du Bro skis

This is the 1st video footage I have of the Corsair with the Power 10 in it. Poor video quality b/c my buddy filmed this from my Canon SureShot...

Here's the first in-flight video with a FCO2. It only lasted about half of the flight b/c the camera stopped working in 20 deg temp. Have since returned the camera and waiting for another one to arrive.

Howdy -

I am relatively new to the RC Plane world but have enjoyed all there is to learn with this hobby and the many people I have met out at the flying fields. I first got into RC cars (RC 10, Optima, etc.) back in the mid-late 80s. Around 1989, when I was in 9th grade, I purchased a Goldberg Electra 6' wing span electric glider. After a few trial and error attempts and rebuilds, I was able to hand launch and catch it after a year or so. I faded out of the hobby when my charger wouldn't work anymore and I became too busy in high school with playing in a band, hanging with friends, and "chicks" to spend time/money on RC stuff.

20 years go by and I find myself thoroughly addicted to this hobby again. I moved out to Utah January 1999 after graduating from UW Madison (1998) to snowboard the best snow on earth and enjoy all the outdoor recreation Utah has to offer. I've been here ever since. Over the last 11 years I landed a great job working for an interstate natural gas pipeline company, Williams Gas Pipeline. I have also spent a lot of time snowboarding, camping, backpacking, dirt biking, fishing and playing in rivers, playing guitar in my band -Charlie Don't Surf, got married in 2007, etc. All in all, I had very little time to spend on another interest such as radio control stuff...

All my interests and things I loved to do in life changed on May 15, 2009 when I "unintentionally" missed the last turn of a straight section on my XR...Continue Reading
