Just as I was logging in to WordPress to write this, I noticed that it is a month to the day since I last wrote about the Beaver. Well I’m happy to report it is now finished and awaiting a maiden flight. Weighing in at 69g is on the heavy side, but I always knew with that much paint there was no chance of a light build, hey ho! I like the way it turned out looking at least and in reality I expect it it will spend most of its life hanging up and not flying.
It was a very enjoyable build, very nicely designed and with accurate laser cutting, all the parts going together well without much fiddling. It is tempting to try another Guillows kit now, perhaps the Edge 540?
Having said that it will spend its life hanging up, I am coming around to the idea of taking the Beaver, the RedWing and the TomTit to Old Warden to give them a little airing in the free flight area, fingers crossed I’ll aim for the MayFly. To that end I’ve bought 20 yards of rubber and some lubricant, so I’m prepared!
After what feels like quite a long wait for the new canopy, I’ve managed to get over to Northwick Park to maiden the Pulse. Lovely October afternoon, a little breeze, almost no clouds in the sky with glorious sunshine. Perfect conditions!
I put 3 packs through her, all completely uneventful, which is how I like it. I tried a few gentle aerobatic manoeuvres and she had ample power to pull round a loops without even using full throttle. I’m now pleased I didn’t bother putting the bigger motor and 4s setup in her.
I had thought about rigging up the ailerons as flaperons, but now I’ve seen how she handles at low speed I’m not going to bother. The stall showed itself with a very slight mushing around, no worrying wing drops thankfully! And landing with just under idle power meant she just floated on and on.
I’ve updated the page for the Pulse which is here. I’ll update that with any significant updates!
After a bit of coding and a weekend away, I’ve got round to spending a bit of time with the Beaver. Next step is to add some colour, I didn’t take any snaps of it in its plain white state, but the shot below shows the wings masked up and the blue applied.
I have since removed the masking tape and left it to dry, tomorrow night hopefully I can get the blue onto the fuselage.
So about 8 weeks ago while we were down here in Wiltshire, I flew the Dynamic-S up at the White Horse and made a bit of a dumb error in reading the wind. I thought it was coming along the slope and hitting the bowel, but I learnt the hard way that actually it was coming from slightly behind the hill causing some horrible turbulence around my normal take off and landing spot. Well, to cut a long story short the DS had a bit of a rough landing, the nose snapping clean off, but otherwise causing no damage. I had a good ponder about how to get her back in the air, eventually deciding that a new fuselage at £20 or so was the easiest and probably safest route.
HobbyKing UK didn’t have them in stock in August, but they came in a week or so ago, just in time for me to transplant the gubbins and get her ready for this weekend which was our next planned trip out west. Friday say a nice day, but with no wind, so I flew her from the flat field at the top of the hill, about an 8 minute flight with no unpleasant surprises.
Today the wind was blowing about 15mph from the North East, swinging round to ENE at times. That meant I had to use the eastern edge of the slope, of which I have less experience. I need’nt have worried however, she was up in the air for a good 30 minutes, with still a few minutes of battery left when I landed so she could have easily flown for longer. Brilliant flight, lovely aircraft on a surprise sunny September afternoon.
I’m becoming more confident with her, rolls are nice and axial and I’m practising slow rolls with rudder fed in to keep altitude. I even managed a inverted circuit, it was a little rough, but I made it all the way round
I’ve included a little pic below so you can see the view I have while I’m up on the hill.
The editor of the magazine I take, posted on the accompanying forum a little while ago explaining that some time back there was a free plan published for a model called the Foam Fing, to celebrate this they had a few of the foam boards printed up with their logo and the name of the model. A few of these had recently been found and an offer was made of a free board in return for the recipient designing a model for it.
One of the other guys on the forum has dug out the original plans and posted them to the thread, they can bee seen here.
This wasn’t an opportunity to miss so I signed up without giving it much thought. Things began to feel real last week however, when the foam board turned up in the post!
I started to sketch some aircraft on paper and sort of started to be drawn to a canard. I sketched a few canards before coming up with what looked like a pretty little thing and with proportions that might work. Figuring that a chuckie glider might at least make me feel more confident, I set about cutting balsa. The result can be seen here, which with a little nose weight seems to happily fly the length of the garden in a nice gentle glide path.
So there we are then, I have a board from RCM&E and three A2 boards I picked up from Hobby Craft at the weekend, and a chuckie glider which sees to fly ok.I want to crack on with the Beaver first, but a plan is forming in my head
A while ago I bought myself a FitBit One to keep an eye on exactly how much I walk, it is a little expensive for a pedometer, but I liked the fact it syncs via Bluetooth 4 to a supplied dongle or to an iPhone. The data can be viewed on the dashboard on their site but also – and this is one of the things which attracted me to the FitBit – via an API. I’ve had it for a good while now and figured it was time to start looking into the API.
The first thing I wanted to do was get the historic data and save it somehow. I’ve got that bit working, I have a php script which is authenticated against my account and requests a given days data which is then saved as raw json to a text file.
I’ve no plans to do anything with this data yet, so json in a text file suits me fine. I can read it with pretty much anything and it is easy to backup.
I’ve put the initial simple code up on GitHub which you can see here.
So a while back I managed to stuff my Edge 540 hitting the nose quite hard and breaking the prop. When I picked it up I noticed the rudder was all loose suggesting I had stripped the gears in the rudder servo. No worries I thought, how could it be to find a new servo? Well the answer is, quite tough indeed! The official part # is EFLR7100, I couldn’t find any UK stockists and going by the USD price I figured if I could find one it would likely be 20 quid or so which seemed a little steep.
After quite a search I found the TGY-D1290P from Hobby King, this fitted perfectly, even including the little JST connectors enabling it to connect directly to the AR6310 Spektrum RX which is supplied with the aircraft. There is a handy extension cable buried in the fuselage, so the length of cable supplied with the servo is sufficient.
I’ve had four flights since replacing the servo, all good!
