I made some careful taxi tests as soon as the glue was dry. Very short "runway, so I couldn't really open her up for more than a fraction of a second. The airplane accelerates quickly. Prop wash pulls it strongly to the right as it begins to roll- but I can keep it straight with full left...

balloon6 Ready to fly! Take-off weight is 42.5 g. I put a bit of music wire in the tail skid, that was my last bright idea. I'll get some nice pics, but here is the web cam of her on the work bench. Started in at the end of September, prototype in early February. I think the real P-51...

:roll1: The wheels are on the model! Plan C turned out to be plan B done better. Each wheel rotates on a short music wire axle with a springy loop holding it in place within a paper tube. The tube is glued to the undercarriage struts which attach to lugs on the fuselage. The metal axles...

Wheels need some work. The old design had too much friction - I feared nose-overs! The new design with bead bearings doesn't track well and is too hard to build anyway. Working on plan C.

I'm a bit behind schedule, but it's a "winter mix" of snow, sleet, freezing rain and rain today and a perfect time to build airplanes. The upper wings are on the model. Upper wings are duplicates of the lower wings. I omitted the hinges from the ailerons on the prototype, but they can be bent...

Pure genius! A great use for used aluminum cans. I Love those Fiddlers Green models...easy to build and they look great. Some people get them to fly, back around 2003 it could be done using the guts of a Spinmaster capacitor fueled flying toy. My E-buddy/mentor Schorhr is getting me...

Just completed attaching the upper center wing section & its struts to the fuselage. A very tricky step...it's best to keep young children out of hearing range 'cause it gets "a little blue." wall1 Doing this well makes it a lot easier to true the upper and lower wings. The cabane struts (I...

soda can airplanes!!!!!! Not until now. Those Cubs are little gems! Can't quite make out the numbers, but maybe 10cm span? I'm working at something close to the practical limit of "off the shelf" RC with my 30 cm Se5a and I fear it would be too heavy. The airframe in this thread is made...

The lower wing is attached to the fuselage and I'm printing the cabane struts and paper "lugs" to attach the center section of the upper wing. The lower wing is easily strong enough to support the fuselage without additional help from the upper wings and struts. Rate it maybe 3 g +/-. My guess...

I could find a million uses for one. Custom servo mounts, motor mounts and control linkage horns come to mind immediately. I imagine the plastics will get better structural properties as the technology progresses. Gluing up the lower right wing as I type (well, not exactly, that would get...

Very nice work on those quad frames! You seem to be learning the art and science of 3D printing with amazing speed. Nylon is pretty tough stuff but ABS has it's charm in terms of rapid programming. Yes, my pics are really terrible. The white model has poor contrast, and I'm a completely...

:car1: The fuselage is completed except for the exhaust pipes and radiator. You might say the avionics are now wearing the fuselage. Sealing the top of the forward fuselage was my "Crossing the Rubicon." No easy way to fix anything that goes wrong after. Passed one more test of the...

The model gets its horizontal stabilizer and elevators. Made to a higher standard of craftsmanship than those on the mock-up. Mass is 29.5 g at this point (battery included. Funny, the model feels much lighter now that the long tail is on. Human perceptions about density are pretty bad...

Sealed up the forward lower fuselage this morning after some last minute wire bundling and rerouting. Clearly lighter, less messy wiring is the next development hurdle. Pic 1. Things look pretty clean if you don't look at the tangle of excess wire just under the cockpit cutout. The ESC...

Your caged ball earrings are way cool.:cool: Very ambitious and the the artistic aspect is great IMHO. I don't see why you can't ultimately carve an airplane "out of the solid" as the Brits like to say. Go for it :thumb: Nothing is too heavy with enough power - although I do recall you...

Inherent stability of the Se5a is one of the reasons I chose this design for my first RC scratch built. Lots of dihedral and it initiates beautiful banked turns with just rudder. Still, with 0.47 T/W it may be a bit hot for me. The prop is on. Just enough clearance. Probably should have...

The glue has dried, so I thought I'd do a little weight check (OK, mass check). Forward fuselage, RX, motor & mount, battery & box, ESC, 2 servos, all plugs & wires come to 26g. Add 1 gram for the prop. The entire paper & glue airframe comes to 17.5 g. So, I feel very confident the entire...

Rapid prototyping is very helpful at this stage. I'm finding a fair number of design imperfections that I hadn't envisioned. Minor things I just note, but a few I fix. The lower forward fuselage is nice and rigid now that I've sealed it up. It will get even better when I attach the center...

Little by little it takes shape. The battery box is now mounted to the underside of the RX jacket. Ready to seal the nose shut forward of the lower wing.:thumb:

Most of the RC hardware is now mounted in (on?) the lower forward nose section of the Y Se5a. It's still easier to work with the pattern unglued, so the whole thing is very floppy. Pic 1 shows a top view, left to right, elevator servo, rudder servo, RX pins, motor & mount. The schematics...
