The Bird of Time is a beautiful and distinctive sailplane dating back to 1979. The plane is nostalgia legal when built to plan, and has a reasonably wide performance envelope, especially for a R/E design. Back in the early eighties, I wanted one but was flying the Maestro Megan and Viking at the time, and really was not doing enough in the hobby to justify building one.

Then the Dynaflite ARF Bird of Time was released in 2003, this piqued my interest in the plane again, but the issues associated with the poorly constructed spar system surfaced. Since it became clear that there was no easy way to beef up the spar on the ARF model, I decided to build a Bird of Time from the kit.

The kit is a real bargain considering that you get pretty good balsa (at least in my kit), with beefy and hard stock on the high stress pieces like root ribs and nice light balsa sheets for the D-tube. Looking at the spar system, it was clear that some improvement could be made, incorporating carbon spar caps and bias fiberglass on the D-tube leading edge. If you are going to modify the wing spar, you might as well do it right. I want to have a wing which is capable of close to 150 lbs. of winch line tension. If this is to be the case, the joiner rod and wing mounting system will have to be improved also.

I am not going to put spoilers on my plane because the original Bird of Time did not have spoilers.

So this kit will be built according to plan but not LSF nostalgia legal with the...Continue Reading

If you get a chance to grab one of these, it's a great flying model. Hobbico/Fliteworks made these from the J-Power V2 molds. With a little work, this P-38 can be an excellent semi-scale model. Fliteworks modeled the plane after the Red Bull exhibition plane. The full-scale plane was originally a Reno racer with carbs, so it had carb intakes, no turbos. With a little crafting, you can make your own turbos.

The model sold for almost half of what a Flightline model sells for! It flies on 3S, 3300 mAh, 50C batteries. I get five minutes of mixed flight on this size battery.

It flies REALLY well right out of the box. It cruises well, with enough power to do a nice vertical climb. I swapped out my props for some 3-blade Master Airscrew props. Don't expect a screaming 90 mph warbird, though.

The weak point of the model is the nose gear. There isn't enough support for the retract mount, so even the best grass landings will eventually loosen up the nose gear. Greasing this model in is easy, though. If you want to pull out the retracts, this model makes an excellent hand-launch/belly-lander.

Cool parts from Formufit.

I have extras if anyone is interested, I had to buy 8 at a time only needed 4.
So I have enough to build another one, but you have to get your own tubes.

Hit me up if you want, $25.

Halloa people

today's entry is very much aimed at people that are new to FPV drones or that might want to try them
Here are a few quick tips.. They are mostly geared towards the Eachine Tyro79S.. which in itself is a quad aimed at beginners..

But the video should also help you along if you go for a different quad

Got the shaft and tube in, nice and solid, spins pretty freely.
Sealed the hull inside and out a, need to sand and prep for primer.
Working on the servos and radio box set up.
Got the rudder aligned and ready to mount the servos.

Check out the box the servos came in!
Smashed almost flat.
Rough ride from China I guess.

Nemesis 2 ( Rat 2 AUS-8 ) (7 min 54 sec)

Nemesis 2 ( Ontario Rat 2 AUS-8 )

Thats right , this knife disappointed with it's inability to hold an edge . Sure I could massage the factory bevel to take hair off my arm , but when it came to edge holding .
Another knife that ended up in the JUNK Knife box ! ( Butt !!! was it a junk knife ? )
I get the feeling a lot of manufacturers seem to be doing junk bevels .

So the Rat 2 got a 20deg 180 grit edge put on .

Surprise / surprise .

Put a decent bevel on the knife and it works
Horrid weather , had lots of wind . And today , more wind + rain and damn .... Just when I went out to cut rope there was a very decent temperature drop .
I think my hand had a slight blue tinge , sure as heck were cold as ice with that wind chill ! So cold I found it challenging to cut the paper .
At the end of the vid , after being inside a few hours , I cut some more paper . That rolled edge , the 180 grit finish , really caught the paper . But with the grain going the right way it still cut . I would say the result was fair .

Colorfabb XT-CF20 Prints
I now have the frame, tail boom, vertical and horizontal stabilisers all printed in the CF20. It does feel much stiffer and stronger than the XT, so I think that the airframe will be fairly robust. I have started the post processing of the parts, giving everything but the frame a coating of XTC-3D, as recommended by several people on the web. This is just a thin epoxy coating that helps smooth the layer lines and hide small artefacts, but I have done a layer, sanded, and then done another layer and sanded . . . and I might have to do some more sanding. I decided to try another print of the rear of the fuselage as it was taking longer to sand it than to try for a better print. The XTC does make the XT more transparent though (see pic), as it smooths the surface and reduces diffraction.
After the sanding it will be time to mask the windows and get a layer of primer on.

Just started yesterday on building a profile F7F using the FT EZ 3 channel power system.
Target scale is roughly 0.38 m / 0.48 kg. Draft plans / skin shown below.

Built a quick model in Blender and now have it flying in PhoenixRC.
Working on creating plans, and have the FT power pack on order.
Also have several sheets of foamboard in hand, so getting close to cutting foam and plugging in the glue gun!
And not that it matters, but all that was done in a single day.

But right now waiting for one of our cars to be serviced, life being what happens while you're making other plans.

In case anybody comes this way - I've written a simulator for R/C planes , mostly gliders since that's what I tend to fly. It's completely free on Windows and mostly free on iOS/Android (limited sceneries/planes in the free version). You may be able to get it to run under linux (wine) and/or OSX (PlayOnMac).

It's not under active development at the moment for a couple of reasons:

* I needed to concentrate on writing software for my own business
* Technical reasons which mean future development would require as significant re-write of the platform layers.

Nevertheless, I hope it's still useful and fun. I've met a lot of people (online and in real life) through it, discovered DLGs (thanks Jenne!), and improved my own flying!
