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 )

Review - Turnigy 3S 2200mah 25C Lipo Pack



Here is a link to the Video:
https://www.youtube.com/watch?v=lNmKxKv_8oA

I order these LIPOs to use on two of my larger planes.
They weight approx. 16 grams lighter than stated in the specs which is great ;-)
I was also impressed with the Internal Resistance of these LIPO Pack.
The lowest Cell Resistance was 3 milliohms and the highest was 6 milliohms ;-)
Not bad for a 25C LIPO.
The LIPO measurements were very nearly spot on with the stated Length, Width, and Height.

Now it's on to perform some field testing of these LIPOs in a Plane, so stay tuned ;-)

Here is a link to this LIPO:

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

The purpose of separating the Cirrus ailerons is for spoilerons and flaperons. Inboard flaps can be lowered 4-5 degrees and each aileron can be lowered 4-5 degrees so the whole trailing edge can be cambered into a thermal airfoil section. Moving the D switch from this position 1 to 2 will put the inboard flaps max down and both ailerons reflex max up for spoilerons. The 0 position has matching ailerons and flaps in the neutral camber position.

The stock ailerons are connected to ch 2 with a Y cable. The left aileron Y is connected to the left white fuselage fixture (lff). This middle plug in the fixture must be removed and replaced with a single cable that will be connected to ch 6/left aileron channel or LAL. Use a small Phillips head screwdriver to remove the 2 screws holding the lff to the fuselage. Then remove the 3 screws securing the 3 black male connectors but before doing this put Sharpie pen marks on the forward and aft plugs since they are the flap and light connectors. The middle connector will be removed and taped over to prevent it from being accidentally used.

HTRC H4AC Duo 2s-4s Dual Output LiPo Balance Charger Review

Are you looking for an affordable, compact, and easy to use LiPo balance charger, capable of charging two batteries at once? If so then this little H4AC might be just what you want.

This charger is about as easy to use as they come. Simply plug a battery into channel 1, or channel 2, or both, plug your balance connector into the appropriate port, and hit the start button. The charger will then begin charging your battery, or batteries, and the display will show the voltage of each individual cell being charged. It's as simple as that.

Each channel has a fixed output of 2A, so the charger is best suited for 1100-2400mah 2s-4s batteries. I have used it several times now on my Tattu 75c 1050mah 4s batteries, and it has been working flawlessly. Cells have been consistently finishing within .01v of each other on the chargers display, as well as when I use my cell checker/balancer which has always been accurate for me.

The fact that this little guy has a built in power supply makes it perfect for those that don't already own a 12v DC power supply. It is also quite small, so it takes up very little desktop, or bench space, and is super easy to travel with. You can see in the picture below just how small it is next to one of my 65mm Tiny Whoop Drones. Priced under $30 and Amazon Prime eligible, this is an excellent option for anyone on a tight budget, or as a backup/travel charger.

Don't hesitate to ask any...Continue Reading

On my last flight I found the throttle setting where level flight (SAFE On) exists with full landing flaps. You read on the top line of your DX TX display. My setting is 46 percent. After landing I opened up the throttle curve program and turned it On and set point 3 at 46 percent. Then I set point 2 a little below at 41 and point 4 at 54 percent. This gives a flatter throttle slope to allow fine tuning when I turn onto base and final approach. Now I can reduce throttle to a nice glide slope setting and just use rudder to maintain localizer/azimuth/runway centerline. It’s no Cat 3 but much better than prehistoric RC flying.
