The Jekyll or Hyde

Just seen your comment on the axles Eric. When I get the wheels & have the camber set that part will be locked in place.

Interesting stuff crash, think it's going to be a case of suck it and see, just try to keep the weight down as much as possible.

I was in the workshop today, deliberating over what to do with this undercarriage, when Stephan turned up. So seeing as he's a pretty good engineer, I asked his opinion. He thought with the four screws on each side & once screwed & glued it would be more than strong enough.
Just to be on the safe side we took it out to where he is working & let a couple of their guys have a look ( wind turbine structural engineers).
After quite a bit of pushing, pulling & prodding, their opinion was that it would have to be a pretty catastrophic "arrival" to break it. The only concern was that the tube may fracture at the cross brace in the A frame at some point. I might take another look at that. Otherwise it will remain as is. Thanks for the input though, it was worth looking into.
Here's another one to look at.

Progress has been a bit slow due to the necessity to earn money ! I have managed to get the complete wing cut & glued together though, bit of sanding then it's ready for covering. Cutting the insets for the servo's was a bit of a pain. I ended up cutting the shape right through the wing, removing the the block, slicing it to the depth for the servo & then gluing the top bit back in. I have enough 12 gram metal gear servo's for everything but the flaps, I don't suppose I could use 9 gram on the flaps ?
Full detachable wing 1840 mm.

Aileron servo cutout. Lower part of the tip is angled in the hoerner fashion, top part left flat to allow fixing of a tip fin which will start just behind the CG point.

Quite a bit got done today, couldn't sleep so got up at the crack of sparrow fart & got on with it. Front half of the Fuz is now in primer & top of the wing covered, I'll cover the control surfaces tomorrow. Next step will be to test & fit the servos, then cover the bottom of the wing.

Servo size is a regular grumble from me!
I am sure even a 5g servo would be quite adequate. Remember you can (and should) use the full servo travel although it only has to move the flap by about half the angle so there is a 2:1 mechanical advantage straight away!
In addition with a bit of linkage geometry you can arrange that the servo travel is not proportional to flap travel with the result that the effective mechanical advantage to the servo rises with the flap angle.
The aerodynamic load on flaps is more or less proportional to their angle, hence the need for placard speed limits when deploying flaps!

Well it's getting bigger. I am not entirely sure where to mount the H stab, Above, below or on the centreline ?

I will try & add the pictures again then!

Looking good crash. Proportions look right. Should be a nice flyer.

Looks good.
There can be aerodynamic reasons on the position of the tail plane but for a tail dragger 'on top' of the fuselage is popular simply because it keeps it clear of the ground but less on a issue with a trike U/C.

Whilst waiting for the fuselage covering to dry out I thought I would get on with the wing & a job I've been putting off namely, the wing tips. I have been trying to come up with a design that will push high pressure air from the bottom away from the wing tip but still be relatively strong.
I thought about plastic fins but that's to heavy & to weak, so eventually I made something in foam. I wouldn't call it a fin, more of a tip fence.

The horner tip shape remains, the fence adds some strength. I just hope it works ! While that was drying I marked out for the VG's & dry fitted a couple. Plastic tooth picks fit the bill nicely & can easily be trimmed down a bit if necessary.

Servos & wiring now fitted in the wing. I decided to paint the bottom of wing & eventually the fuz black,as it stands out well in the air, plus I can see which way up it is ! I wasn't happy with the undercarriage, so that has been rebuilt. It is now 50mm wider ( per side) & the axles are positioned just about level with the wing leading edge. There are now a total of four springs per side, two internal & two external. Travel is around 50mm when pre loaded. It is made from 8 & 6 mm aluminium tube plus a few bits scavenged from light fittings!
Wing braces are 6mm ali tube slid ( & eventually glued) inside plastic edging strip, which just happens to have a nice aerofoil cross section.
These are screwed to hinges glued into the wing at one end & attached with 4mm screws into crimp nuts at the fuz. Making it easy to remove the wing for transport. The hinges are modified strip light diffuser hinges, I know i'm cheap but necessity is the mother of all invention! The wheels in the picture are just for demo purposes, it will have grand tundra wheels when finished. [attachment=23043]

Looks awesome Crash.

I love ingenuity when people adapt things like your hinges.
