nar·cis·sism - extreme selfishness, with a grandiose view of one's own talents and a craving for admiration, as characterizing a personality type.

I do not frequent this forum as much as I did in years past. Wait, let me rephrase that. I do not POST in this forum as often as I did in years past. Why is that? Mainly because there are way TOO many self appointed, narcissistic genius' that know everything there is to know present here. Since I am not as self absorbed and insecure, I do not feel the need to contribute to threads as often as I used to.

Being a glow engine person about the only forums I look at are the Engine, Fuel Plane Talk, and Aircraft - Fuel - Engines and Accessories in the Classified section. I might look at Trader Talk for some comic relief now and then too.

But man, there are a few daily posters that just cannot help themselves when it comes to 'one ups man ship' and feeling that incessant need to post in EVERY thread possible whether what they are posting is relevant to the subject of the thread or not. These people often derail the original thread topic to their own agenda whenever possible. I can only wonder if they were not held or hugged enough as a child. What horrors have they experienced to need such constant attention and the feeling to be superior?

At first it was somewhat comical, but of late it is a real put off to even reading the posts in this forum. I suppose this forum is not special. These individuals most likely exist on other forums too. At least in the past, before the advent of the internet our/my contact with such people was minimal or extremely limited. Of course that was also back in the day when such people were dealt with in ways that, in today's mamby pamby society, would get you sent to jail. In the military these 'correctional' deeds were referred to as 'blanket parties'. It was amazing how behavior was modified and 'adjusted' quite readily then. Ah, the good ole days....

Alas, today the world is filled with keyboard confidence and big talk.

Still windy ( Gale force ) = Oh dear !

The blue bomb ( hand throw plane ) = Bent bird .

So been trying to find the CG ...

To this effect I used a fair amount of Hot glue and the plane still flew like a spear !
Though ! .. The more weight added to the back , the further it went .

So I gave up on the hot glue and moved to LEAD .. ( Lead shot to be precise - No4 shot ? I don't know )
If you look at the pictures , I made two holes as far back as possible and then pushed lead shot into the holes ..
First two then four , and each time the plane glided better ...
Bottom line , it took 14 pieces of shot + a bit of foam safe cyno .. ( Glue the shot )
So in one of the pictures you will see the mould line where my CG currently sits just a little behind ..
I would suggest @ the mould line or just ahead if you plan to RC ( As a starting point )

Thats it for this one , I might Chuck it some , but I will not RC it , just too many funky bends ...

I did mention in the previous thread that I fixed the elevators with some laminating film ..
Me thinks olds likes the laminating film ...

I didn't mention the model in the photo on my last blog because I hadn't yet flown it.

This, I must say, was among the most pleasant surprises I had in a long time.

This was one of four models given to me by a friend who had a kit manufacturing company at one time. The proliferation of ARF and RTF models, while expanding the hobby as a whole, hurt his business.

Anyway, two models were complete and this was one of the two complete models. The other was a three-channel airplane of his own design called "The Sparrow." I'd seen this model fly and I now own it. Unfortunately, the servo arm for the rudder broke in flight. I'd never seen one fail! Damage is done, but fixable since it crashed in thick grass. We're getting together soon to assess and repair the damage. It's just too cool not to. It strongly resembles a Fokker Eindecker with a toy bust of Anakin Skywalker in his podracer goggles at the controls.

As for this powered glider with a brushed Jeti ESC and motor, an ancient ArtTech 1300mAh 3S li-po and an even more ancient Hitec 72MHz AM receiver, I dragged it into the house to investigate the possibility of a brushless upgrade.

Cleanup began right away and while I knew the glider was in good shape, I didn't know just how good. Revealed beneath the dust was a nearly new, magnificently constructed model lacking only a canopy. No scratches on the wing and almost none underneath the fuselage beyond what one would expect after only a few...Continue Reading

Review & build log of HOBBYMATE Comet VX220 Stretch X 5" FPV quad DIY, PNP, BNF - 1800KV (6S) or 2500KV (4S)

I recently tested 145mm DIY KIT from HOBBYMATE and it was fun to build and fun to fly because it flew great and I had zero issues with it so far.



Now I will build and test HOBBYMATE Comet VX220 Stretch X 5" fpv racing drone. Its a high-performance racing drone as manufacturer says.
And from my unboxing experience (pics are in gallery) all parts in the box look high quality. Hobbymate didn't save any money on selection of part for this quad.
And, most of all, all that at most welcomed price of 180$ for DIY KIT.
Comet VX220 comes with airbot F4 V6 flight controller and typhoon 35A (Max 45A), simple connection between the fc and esc is done with a 8pin cable, which saves your time in building and maintenance.
If you don't have time or experience for self building it, you can select prebuilt version in PNP or BNF format.



Description:
Comet VX220 fpv drone is a combination of high performance, stability and durability.
Low-deck design means centralized mass and excellent handling.
Stretched-X motor layout is the choice of top racers because the rear props are further from the "dirty air" coming from the front props.
The result is smoother cornering and higher top speed.



Features:
  • 5mm full 3k carbon fiber twill
  • High quality 12.9 class Steel counter-sunk screws on the drone
  • Airbot F4 V6 flight controller, tested and

The remaining Modes are Thermal and Land. The Cirrus’s trailing edge camber can be set to about 3-5 degrees down to increase the camber and lower the thermal speed. Since the speed will be lower I would set 100 percent on the D/R menu. The elevator setting could be set on the TX and it will be remembered. I am usually in a turn when in a thermal so I put in a little more up elevator trim. When I roll out and go straight I may see pre stall porpoising so I take the trim out. Of course you can cheat and put SAFE Self Level ON when thermaling (or searching for a thermal). Purists will get upset but Cirrus is your model. When both ailerons and flaps are cambered down you are at greater risk for stall because there is no washout on the wing (like you will get in Landing Mode). So stalls can be dangerous unless you have about 100 feet or 10 seconds to recover. Here is my stall recovery procedure:

Go full power as this will put you into the Launch mode. Flaps and ailerons will retract intoa minimum wing drag configuration. The prop blast over the elevator will allow more pitch control. If Self Level is On the nose may be down and so up elevator will be applied automatically. If the stall has not been broken then apply down elevator and opposite rudder (if a spin or spiral is seen). Down elevator with prop thrust over the elevator will cause a dive and increase in airspeed where recovery is possible. Now this is theory and will be flight tested...Continue Reading

Other reasons for Flight Modes is to deploy flaps or spoilerons or flaperons. For example in the Speed FM you could reflex both ailerons and flaps to streamline the airfoil to go faster with power off glide. Of course you would most likely put in down elevator trim to achieve a 10 degree nose down attitude. This would be with SAFE On or Off. In SAFE ON the flight control movements are much less than when Self Level is On. This is OK and is to be expected. In the D/R & Expo menu you could scroll the Switch position and select Flight Mode. Then you would most likely set a rate and expo value at high speed that would not be too much but comfortable and not pitch sensitive. There will be more on this when I go into flight testing and adjustment. More on the FM Table:

Spee is the FM for power off and best dive speed. If you like to dive at a vertical 90 degree descent or a 10 degree glide angle this is your Speed Mode. You will go faster if your prop is feathered and not turning (or windmilling). That’s why I will be using the 60 amp ESC with a programable prop brake. Later I may try a folding prop. Lets say your full throttle dive speed is measured (or estimated) at 60 mph. If your brake is strong enough and you can stop the prop your power off dive speed will be greater. How much? I had a motor glider that doubled the speed. Full throttle gave me 60 mph and power off folded prop gave me 120 mph. Of course the Cirrus is a different...Continue Reading

These settings are for my DX9 TX with the stock SR22 AR636A receiver:
1. Throttle
2. Right Aileron
3. Elevator
4. Rudder
5. 2 Flaps on a Y cable
6. Left Aileron
7.
8. SAFE Self Level On/Off on switch B (You can use channel 7 if you have a 7 or 8 channel TX.
9.

If you have not used Flight Modes you are in for a treat. Ever go full power and the model pitches up and over (like the original Radian). Just when you get both hands on the TX it’s too late. In Flight Modes you use the Throttle stick for 3 different Elevator trim settings. So for high throttle you would use down trim.

I made a copy of the DX 9 program that was used for 5 flights just in case I wanted to go back to a working program. The copy was reset when I went to the Sailplane Type Model. Why not use Airplane type? Because the Sailplane program has Camber Presets and more Flight Modes.

This is my Maiden Flight Review video for the new E-flite Night Radian RC Glider. It has Flite Test stickers and is a 2M Glow In The Dark Powered Sailplane.

E-flite Night Radian RC Glider - Flite Test 2M Glow In The Dark Powered Sailplane Maiden Flight (3 min 52 sec)

In the video I hand launched it in SAFE Mode, flew it around on power, did some gliding, and showed off how well it loops.

Here are my review notes:

Pros
- It is a big E-flite Radian Powered Glider
- The motor is a 3S brushless motor
- Not only does this comes with lights installed, but they offer a ton of variety
- This is definitely something you can add an FPV camera to for more fun
- If you're a Flite Test fan, this plane is for you with the stickers and such
- The radio setup is easy like most Horizon Hobby products
- It comes with the option of using SAFE Select
- AS3X is nice when you have SAFE Select turned off

Cons
- The CG is printed incorrectly in the manual and may cause issues flying it. I found that a touch past 3.25" was perfect for my enfan 1500 lipo battery on the maiden flight.
- The tape provided to hold the horizontal stabilizer is unacceptable. Use quality shipping tape instead.
- Wires that connect the horizontal stab to the fuse are a free floating afterthought.
- The Servo tape that covers the wing lights underneath the main wing started to roll up after the first wing installation.
- The LED wing wires are going to be a hassle every time this plane is flown because they are about an inch and a half too short. To help with this, I added some servo connector extensions. I highly recommend this!

Nifty table of all the SECO orbits. The speed & altitude can be derived from the webcasts, but the inclinations are not broadcast. Not sure how they calculated the inclination change. Even without inclinations, rough calculations based on high school geometry showed it achieving abnormally low orbits. The table confirmed those calculations were right. To recover the booster after launching a 7000kg satellite, it can only reach an elliptical 11000 miles. That's lower than GPS. It's a long way from the direct GEO insertion advertised but never used by the delta IV heavy.

I had a dream !

I saw this jet looking hand throw air-plane and thought !
Hmmm , dont they have these small EDF units ..
That foam job looks like it would take a 30mm EDF , a 4ch Rx and some small servos with little trouble .

Well the other day my hopes and dreams were shattered when the foam job arrived .
It was seriously twisted out of shape . I don't know .
Looked like every toady between my home and China sat on it ..

Pictured is about as straight as I can get it .. Not going to try and RC this one ..
Do I try again ? Dont want to buy another bent bird ....

Anyhow , 2 more 35cm gliders arrived ..
These two glide sweet , sweet enough that I may give it a go ( RC them ) ..
Hmmm , elevator / rudder or pitcheron ... Or , one of each !

FX 707 Update :
I did mention that the sleeved control rods bit the big one ..
Ordered some 0.8mm music wire from HK ............ and it was binding as well .
Thankfully I had some 0.6mm from a previous order and when tried was as smooth as silk ..
So swapped out the control rods from 1mm to 0.6mm .. ( no choice really )
The FX 707 is fully ready for testing now ..
And it be the 3rd day of rain today .. It has hardly rained this year , and when I have two gliders ready for chuck testing - it rains .

( Just let me win the lottery and we will call it even )
