Hey Bargle,

Ever get this guy in the air?  Curious to see how it trimmed out.

_SHig

Not yet, Shig. I am planning a flying session later this week and will be taking that one along. I'll let y'all know then.

OK, flying session went well. I'm using a double loop of 3/16 rubber a little longer than the nose to peg length.  It needed a 3/32 + a 1/64 right side thrust shim with 1/32 under the wing spar. On 650 winds I got a 1minute 8 second flight. I'm pleased with that. Doesn't seem to have any bad traits. Yay! Here's a pic. Sorry about the poor quality. I forgot my sport viewfinder and had to set the zoom a bit wider than I would have liked.
Oh, I've decided to nickname this one the GollyGosh.

Cool!  Looks like you totally re-covered it since the debut?

No, that's still the original covering, warts and all. Are you maybe thinking of the downsized Miss Canada? Yellow and white. That one is being a pain. Or maybe my fullsized Gollywock that's yellow with purple trim?

Ah yes, I was expecting yellow and purple.

1933 Farman-Renault P-nut

This one owes much to M. E. Bollman's 1975 rendition (also a P-nut).  His, with a RETRACTABLE mono-wheel undercarriage, is much sexier than mine is.

It's a grimace:  Stark fear.

Both of the mono-wheels had less then stellar careers...

Thank you, Jon.

The prop is carved ( McComb's "X-block 2" block design), and the spinner is laminated from lots of cross-grained 1/16" balsa disks that are mounted on a bamboo mandrel and spun to shape.  The spinner is then notched with a dremel to receive the prop (no free-wheeler).

I use "pawlina" wood for props these days, not balsa.  It is quite light; carves, sands, and seals nicely; and seems to have sufficient guts to allow one to carve a reasonably thin blade.

The finish on the prop (and the airplane) is Deft Brushing Laquer

Very nice! I've seen pawlina but not used it myself. It was the thin-ness that made me think it was laminated...

Hey;

This is my prototype altimeter.  It's not an airplane but it might be useful in one.  It records up to 500 samples of altitude data in one meter increments.    When the start button is pressed it begins recording and after the flight the data can be downloaded to my laptop through the connector tab.  With a 10 mAh cell it weighs 1.3 grams. 

Right now it samples once every second but it'll be adjustable so I can have it sample rapidly at the start of the flight for things like cat gliders or F1B/C/G.  The same controller unit I use for my other timers and doodads can be used to make these adjustments. 

I've been wanting to integrate an altimeter in my FF controllers for a while and this is the first to try some experiments on.  The processor I used is the same I am using in my new controller design so if it works out it will be easy to expand on.

I just finished it and can't wait to give it a go in an airplane.

Hey climber, how does you altimeter sense change in altitude?

Just asking because I mess around with larger planes. I know how a regular sized altimeter works. I'm just curious to see how yours works.

Hey there;

The sensor reads temperature and barometric pressure which can be used to calculate the altitude above sea level.  The model I used is the Bosch BMP085.  It's pretty cool.

Here's something different . . .

I've eventually got around to finishing my version of John Pools famous 'Never Forget' tailless. 60" wingspan with a cartload of rubber in it. The prop is a different layout to Johns original, but similar PD ratio.
Peter (PeeTee) will be pleased to know that it has a fuse DT because I wanted to keep things simple (as ever)

It took me a while to sort out how to make the DT work to my satisfaction (although the last couple of tailless I built were in very little danger of needing one) Wink

A really enjoyable build (those geodetics change in section along the wingtips)

DaddyO:  Beyond cool!

I have to ask...given the...minimalist... nature of the ship, what pops or drops?  At first glance, it appears that popping or dropping anything would result in something a lot more dramatic than "dethermalization..."

I also experimented with flying wings many years ago.  Like you, I found little need for dethermalizers

Glad you like her.

Wordguy - one of the nice things about tailless is the DT. The trailing edge of the wing pops up and they come down like a hawk in a stoop (That's assuming they've got up high enough in the first place) Wink

For those who weren't aware John Pool was THE tailless guy and flew many different styles (inc. a return gear feathering biplane at one stage) Shocked

Funny you should say that Caley - I always thought what my last one needed was a tail!
