Dang didn't realize how small that jet was till the shots of you holding it!
That's micro surgery! Nicely done.
Here's my latest. After a failed first attempt. (found out oil based poly and foam don't mix) Your basic everyday E-flite Super Airliner, modded into the Banana Republic Airliner.
Didn't take a lot of photos during construction but there were a few along the way.
Let's see, first off was fitting electric retracts in it. I cut a second lower hatch forward of the original in the fuse, for access. Built a mount for the retract to sit on, then to give it added strength I filled the whole area with expandable foam. Making forms for the front cooling intakes for the foam to form around.
Little work and I made the new front hatch, soon to be the gear door frame, easily installable/ removable with a pair of screws and one locating tab.
On the wing it took relocation of the original mount plates, and splitting them so I could bury the retract body into the wing. This lets the gear fold up flat against the wing. Cut outs were made for the wheels to fit up into, and additional bracing added to the wing to compensate for the foam removal.
Decided to improve on my last one by adding gear doors. Had to wet form the balsa to fit the curvature of the fuse. Once dry they were glassed on both sides to hold the shape. One servo operates the nose gear door, and one does both main gear doors. Servo module snaps doors open and slows their closing for the gear to clear.
That done I finished up the wing. All wiring was run, servos installed, and a pair of air scoops made for cooling the esc's. Bottom of the wing was then glassed, and top of the wing got paper/poly treatment.
If you look close at the photos, I had to use Christmas wrapping paper on the wing, as newspaper wasn't big enough to do each half. It worked.
On to the rest. Fuse got the same treatment, paper poly on the outside, and I ran some glass on the inside. Tail feathers all were glassed after CF rods were installed for strength.
Of course also saw the installation of the elevator/rudder/steering/nose gear door servos and control rods.
Followed by weeks of sanding, prime coats, and more sanding.
More mods followed. I decided to do it up big time. I added working NAV lamps, wing and tail strobes, beacons, landing lamps in the wings and on the nose gear, cockpit lamps, and tail emblem lamps.
Three sets of boards operate them. The landing/cockpit/emblem lamps come on automatically when the landing gear extend, and snap off when the gear retracts. The other lights are tx switch controlled. All lamps are 5mm high intensity 12 volt LED's.
With all that I figured I'd re-power her. Out came the 64mm 3 blade fans, and a set of Change Sun 70mm 10 blade units were grafted in. To make maintenance easier I made the nacelles so they could split apart and are removable. Screws hold em together and bolts/blind nuts hold em on They got a glassing job too.
I left the fan shrouds in the stock location in the nacelles, but also wanted to use the shroud lips for better performance. This meant I ended up with a 3/8" gap between em. Not a good thing. Little woodworking and I wet bent a pair of balsa strips to fit the gap, so no obstructions in the flow.
Then some fun. 8 servos, 3 electric retracts, 3 control boards, sequencer, rx, bec, two packs (one for motors, one for electronics), 2 esc's and motors, and 15 sets of lamps means a heck of a lot of wiring.
To keep it neat I ran all the wiring for the lamps in the top inside of the fuse, the servo leads went in the bottom of the fuse. Bec sits on one side behind where the motor/esc wiring runs. Rx (2.4)sits in the tail far, far away from any electronic interference. Control boards and sequencer occupy the opposite side of the fuse from the bec.
Mini pack sits up by the nose gear, and main pack also is fuse mounted on the CG point.
All wires are run in separate conduits made out of clear plastic straws, keeping it all organized, neat and out of the way of everything else.
Then it was onto the wing. I had to figure out a way to make the servo and retract connections, plus all those lamps that were on separate circuits, nor forget the esc/motors all plug in and work.
Plus I wanted a safety switch as once the wing is bolted on the main pack is not reachable.
Made my own servo extensions so I had no excess length to deal with on the wing end, built a set of servo leads from the rx to the front wing mount. There I mounted the ends on a block with each marked for what it was.
For the lamps, I dug deep into the junk drawer. And came up with a 9 pin set of plugs off an old PC. Worked perfect, soldered the lamps to the male end and mounted it in front of the retract bay. The female end got wired to leads running to the control boards in the fuse. Simple one plug in for all the lamps. Bullet connectors were used on the esc's due to the amp load, so it was a simple deal making up an arming harness that is accessible from the nose hatch, and still allows the connection between the wing and fuse.
All done, it all works as intended, and no glitches!!!
Then I had to take it all apart and out.
It was paint time.
Wasted no expense there, Rustoleum rattle can paint. Yellow, red, and black. Approx 2 weeks of painting one color, drying time, laying out the next, more paint, more drying, more tape, more paint, and final drying time. Laid on the decals, little hand lettering, and she's just about ready to go.
Ended up I wasn't happy with the motors I chose, so I've got another pair coming for more power. On a side note, the new fans sound fantastic.
No normal edf whine from them, they have a turbine sound. Air rushing in and out with a slight whistle.
Pretty cool, I had drug the wife out to see it, she's used to me and my toys, and usually all I get is a roll of the eyes and a shake of the head.
Had it sitting on the floor, all the lamps going, and just as she's about to give me the look, I tap the throttle. Eyes go wide, and jaw drops!
She goes " It sounds just like being at the airport!"
Good enough for me.
