McDonnell XP-67 "Moonbat"

[Matthewdupreez]

LOL did you take me seriusly?
i meant it as a compliment...
now i gotta read your whole post............................................................................aaah yea you do build really scale but just remember that where there is a will there's a way...
i currently would never be able to fly any of your planes i'm still using training wheels (3ch, and lots of poly or dihedral)

OF COURSE i did.. ha,ha .
Just found it was time to say a bit more , since for shure some wanted plans eg. to build it them self.

Thanks ! well.... hiring is in doubt.., I havent exactly made many airplanes for easyness in build... most are more or less "some complicated". , as this model here too, the Moonbat, it wouldnt be easy as a kit , and a shop servicesenter would be overworked explaining in build techniques.
Eg. customer: "help me, i dont get it and wanna fly it tomorrow!" support: " as stated by ordering, patience, trail & error,individual adjustments is in need of most parts" - customer: "yeah,yeah, i bought it to fly" - support: "have you ever made domeshaped skins by foamboard before?" - customer: "noooo" - support: "do you understand how?" - customer: "no" - support:" have you angled correctly ALL skin edges to fit joints?" - customer: "no, just a few?" - support : did you maked them with reducing angle?" .....and further on it goes

In build difficulty on a scale from 1 to 10, this is for shure a 10. (even more like a at least a 12..)
Such builds will be a "one off" custombuild, not a "mainstream" one. Its some trail & error in the building, even if had a kit. Just to get the parts straight in correct angles, the nacelles, wings, rear, front was a lot of boring work with laser levelling/line and adjustments before get glue stick. I needed make a "jig" for keep the "proplines" correct.

even if would be pleased to see other could build and fly "this thing" too, its too many parts in foamboard eg. that isnt correct to the "paper plan-parts" when fit on the plane.

I like to trigger my own creativity, to find solutions to achieve the result i wants.... but it dont mostly make it easy to follow for others, "sad"
enough.

A 12? If someone was to ask me, "How hard would it be to do the Moonbat out of foam board?" I would give it a 14 out of 10. When I am reading your thread, U make it look so easy. I am glad U stated that to bring us back to reality.

aaaah who wouldn't want to build on themselves??

well, a post now and then, dont show the work you know... just to get the front retract steering functional, i used approx 4h , with different approaches.

Ive been working with the front retract hatches a couple hours already, have thought how do it, but not made it yet.
Its in two different parts. the front "hatch" is fastned to the retract leg, and follows it up "to vertical". The other part in back, should be opened sideways 90 degrees on the opening...and stay there! And be closed again by the front part "pushing it down" to shut.
It seems like must use a couple parts of thinner bendt SS rod, and a magnet to hold it 90 degrees open... (or something alike..)
....and if so, ineed alter the length of the wheel leg (again) , to get space for the "actuator rod" in rear...

So complex! I don't know about you, but this is all part of what makes this hobby so fulfilling! Trial, error...error,error.... success!

Oh ,I know it all too well. Except for the fact I spend a lot time on the trials, that I end up taking forever. This goes with everything I do. My wife is insisting that this should be put on my tombstone. " Damn, that took longer than I thought"

agree @Homey !! to TRY is essential for possible success. Sometimes its get great, sometimes "down the drain" and another approach is needed. Its when not trying your ideas, trigger your creativity, are afraid of errors, things stop.

Even at this build i now need make another approach with that front retract hatch. Its not possible make it as wanted, without rework the hole front, and get the retract center of movement further up into the opening. Well, i tried, i know the possibillity for use perhaps on a later project. ... it will get two hatches in longitudinal axis direction. Easier to get functional, even if liked the other style....

I'll be building it for sure when the free plans are released!

forget it... i wouldnt make plans..... because dont know everything in sizes my self. individually fitted to the main internal parts as on first picture in the thread. That is all i can provide, how they are .

Thanks!
ordered space at paintshop the coming week. (yes, i paint it my self, but nice having a superb place doing it... with all equipment)

Lucky you. I have just joined a makerspace and now have access to some pretty cool equipment. Unfortunately they don't have, and I can not find a spry booth rental in my area. So now, I am ordering this thing. I use to have a make shift booth in the garage, but since I cleaned it out, my wife is insisting on using the garage for the cars.

LOL, when I first met my wife she had never parked in a garage less even a heated one, I had 2 vehicles, the shop's plus my TA so she parked outside and it didn't matter if it was 40 below it wasn't a problem. Then I sold my TA and her van and bought a new vehicle and figured I would let her drive it because I still had the shop vehicle so that meant she started parking in the garage. Now I can't get her out

My neighbor is a pro car painter for many years, and a few years ago, i was helping him build and setup a garage at home, to fix minor paintdamages for customers. Free for me to use, equipment eg. (need pay paint though ) IF its spare space. Ive done a lot car painting, custom paint, lettering, airbrush work before. He have a car working on there at moment, but believes its ready delivered to the customer in a couple days. And now he "hangs on" putting in another till im finished . I help him, he helps me
