Perhaps some more images? I can't see the dihedral from that perspective. It just looks straight.

Is the fuselage a four-sided affair with the curvature via bending? I was thinking if I did something like that I might build up the pieces a little and then sand them down to get more scale-like curvature. Your plane isn't at all bad, but I like real curves for scale stuff. You know -- if yer gonna do scale, go fer the bendies. As much as I whine about low labor for profile planes I'm the opposite for scale.

Check out the build thread on it and if you want to build one he put the plans on the thread also.

My UFO above uses it.

Hi ConstantCrash, you've got me interested. Could you tell me (or point me to a post that does) how you go about using what's essentially silicone caulk for a hinge? I'm getting tired of re-re-re-retaping the hinges on my foamies. Thanks!

Is it me or does it say right in the Lexall ad that it does not adhere to foam.

Logged 2 more flights with the new P-51 and she is flying great for a small P-51
I have a small area to land in but by doing a lot of circling and slowing her down i can manage ok.
Not a scale Mustang but a nice flyer anyway.

One of these days I'm going to get around to making a video of how I do my hinges because my method ends up in a perfect or almost perfect hinge every time. Regardless of if your using lexel, tape etc.

Unfortunetly I've got some other projects I'm working on that I really need to finish before i can get around to it.

Then you are obviously not using 3M Extreme tape. This is the stuff with the cross weave nylon or fiberglass or whatever it is embedded in the tape. Expensive stuff, but tough as nails and sticky as all get-out. I've done a couple of planes that have survived countless crashes and repairs without ever re-taping the hinges.

My original Smart Dart XS is a survivor of a nose-destroying crash into ground under power. I finally needed to touch up the hinges by heating them up with the Monokote covering iron set to low heat. Works perfectly, and now the plane is good for another year and several hundred more flights. Yes, hundreds. That is really, really good tape.

Here is the start of my PinkStar build
The plans were done by Martin Chou

Cut the pattern out
Taped one side
Drew bend lines on other side
exercised the lines to get the curves
epoxied the tail
hot glued the seam in front

next i will work on some formers for the inside.

Default finished scratch built

Finally finished the scratch built I started a few weeks ago and it has the video cam mounted. Waiting for this cold wet winter weather to subside so I can fly. NZ has had the wettest winter for years and all the local paddocks are waterlogged.
Have used the small Turnigy video cam in the car and around home in the meantime. Good value for $18-59 from Hobby city. File sizes are large but I use "Format Factory" to convert the file type to a better format

Interesting looking plane there Enkay, what kind of motor?
Is that a steerable nose wheel there?
Hope it flys good for ya.

No nose steering. This is line it up and point and go.
The motor is a Turnigy 22-13 20 turn 1050KV 19 A brusless outrunner. I have tested it with a 9 x 6 APC prop at 228 Watts. Just over 19 amps.
Cost $11-93 from Hobby City. A more powerful motor would have been a KD A22-20L outrunner 1000kv --25A. Cost $13-99

Well here she is all finished and ready for the maiden.
After the maiden i might put landing gear on it and see if i can fit a spinner on it also.


She came in at just 10oz without the Batt.
Nice and light.

Too late Chellie, i already did the maiden last night.

Hand launched it and it looked like it was going up ok.
At about 15ft. in the air she took a hard turn to the right,went into a steep bank and i could not correct.Might have been a stuck servo.
Any way i enjoyed the build.

Ouch! Are you flying 72 MHz? Could it have been a radio hit? At any rate you'll want to exercise those servos plenty after a failure like that. I've had servos that had apparent bad spots in the feedback pot, but after nearly a half hour of continuous back-and-forth on a servo exerciser the bad spot goes away. Probably a bit of gear grease on the pot.

Where im at a radio hit is unlikely but it could have been a sticky gear in the servo.
I have that servo in an other plane now and have not had a problem so far.
I know i probably should have thrown it away and bought a new one but im kinda cheap that way. That's why i build with dollar tree foam.

Man. I'm glad you have the patience for all those slots and tabs. I hate 'em. Nice plane, though.
