XK A800 & WL F959 (11 min 0 sec)

Havent flown these in a very long time ..

XK A800 was flown yesterday and the F959 was flown this morning .
When I left home this morning there was a slight breeze ...
Nothing to worry about right ?
By the time I got to the park , it was a wind turning into a Northerly Gale ...
Oh well ! The F959 actually handled that wind reasonably well .. ( Could have gone without the wind ) .

Face track run (1 hr 0 min 8 sec)

Complete face tracked run. It does a much better job than a lion manually pointing it. The only downside is not being able to manually point at something else.

A FLZ version of this glider which I started from a WIK design which after finding factory drawings turned out to be very scale.
The original Eppler e195 was compared and replaced with the with the NM 32, a profile intended to improve the performance of the famous HQ profiles which are legion on large flap or non-flap gliders. This profile may be a little thick for this scale especially at the tip where the original had a 9% e174. Scaling the design up to 1-4 should be relatively easy in FLZ-Vortex.

Got the fans mounted and the nacelles assembled yesterday. Filled all the divots with light weight spackling (sp). Spent the morning sanding with 220. Still have more to do. But just for grins I decided to dry fit all the parts. Going to try something new. I usually cover pink foam with brown paper and 4-5 coats of polycrylic. In an effort to save a bit of weight I'm going to try this thick water-based polyurethane. Well see. I'm also going to line the battery compartment with lightweight corrugated cardboard (USPS Flat Rate box board). The nose is a bit wiggly.

After two scratch built planes among one I designed myself (C-152) and a rather unusual Flyingboat (S-39) I was looking for a funflyer easy to build with compact dimensions. The choice fell on the RBC "Viejo" kit which seems to be pretty easy to build and is a lot of fun to fly.

The wingspan is 890mm and the take off weight should be around 650g.

The quality of the kit is very nice and the documentation with a 3D pdf included is very good.

Here's the link to the build log.

Have fun

I am going to Start a Build on a Great Planes T-craft kit. I think I am going to power it with an O.S 30FS. The covering would be a vintage "Toledo Special" kind of look with Hangar 9 Ultracote "Smoke Purple" and "Cream". I don't know if I want to size up the fuel tank, but I'll decide on that later. Any tips on building this aircraft? Pictures will come.

Repairs are coming along slowly. I finally decided to start repairing the tail and found the F-16 part (horizontal stabilizer) was no going to fit well. So I ended up using half of a V900's horizontal stabilizer instead.

After fitting the half into the mount, adding a bit of carbon fiber tubing along with a couple of nylon screws and carbon fiber rods, it was time for finishing the canopy attachment: magnets.

Then came the initial electrical trial with the servos and the AR637TA from my Conscendo. After a couple of adjustments, everything seemed good.

Next, I'll add in flaps to slow for landings, after that will be the bottom plate and retracts.

A fellow clubmember stopped flying his Avistar about 4 yrs ago. He was using a Rimfire 46 with 12/6 on 5S 6000 Graphene, YEP 120 amp ESC. Lots of power and speed but heavy at 8.08 lbs. 1387 watts so I wanted to reduce power and weight. She is down to 6.5 lbs and 645 watts using a 2200 4S 50 C pack and an Aerostar 80 Amp Reversing. ESC to reduce landing rollout distance. Iím looking forward to seeing how the 24% weight reduction does for endurance and performance.

Being in the radio communications industry I had to do a lot of testing of radio equipment and often used a dummy load with a RF meter or other equipment.

Another type of dummy load would be for checking a power source. This would be on the idea of like checking a car battery with a load tester for example.

One thing I found very useful in RC planes is to evaluate the reliability of the
Receiver Battery/BEC using a dummy load test.
Unsure if you're receiver power source is up to the job of reliably supplying power to your RC aircraft system? If not it could be a very short flight especially if you're the one who built it. Just because it works on the ground doesn't mean it's going to continue to work in the air reliably. Many of aircraft have crashed because of this situation. When servo's get moving, they put a load and noise into the system and sometimes the receiver reboots in flight causing a crash. You can have the best radio system there is but if your power source isn't up to the job, you may be the one at your field making the Walk of shame.

I have used 4 x 1ohm 10 Watt resistors in series for testing receiver power sources connected to a servo lead. This gives you the option of going from 1 to 4 ohms depending on the kind of load that you want to add to your aircraft. The link below will go into detail and how to do it and what you need. If you don't have Telemetry or Vmeters or watt meters to use, simple math is all you really need to do this test with the resistors and servo lead. If you connect the resistors directly to power source than a servo lead is not needed, just the resistors.

The link below shows a simple way of adding a dummy load to your receiver power source to see if control is lost due to a lack of power to the receiver. The link also goes into many other problems you may run into in RC aircraft.

Halloa people
