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.

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

In the video I unboxing it, go over the parts and pieces, show you what it looks like after assembly, provide a light demonstration, discuss the radio setup, and provide my review notes at the end.

E-flite Night Radian RC Glider - Flite Test 2M Glow In The Dark Powered Sailplane Unboxing & Review (17 min 5 sec)

These 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 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!

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 questions you might have. Happy RC'ing!!

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.

In my last post I mentioned my interest in building a Micro 2.5 inch quad primarily 2S (meeting MultiGP MIcro class specifications) with some 3S.
Below is a video of how I went about choosing each of the components to include the options i was looking at. It includes the parameters for each component I think are important, options for each component, components specifications compared side-by-side with each other and my choice for each component. This stuff may help out others fairly new to builds also.

This is the second attempt to build these engines , Gave up twice and finally gathered enough info to make all the parts and cast the molds. I finally made enough parts to make about five engines...Continue Reading

After losing my other spitty to an electronics failure, I bit the bullet and built another one immediately after
This one has a few mods that made it better than her deceased sibling...
- Shorter and lighter tail for a better CG location without the need of ballast
- Much better retract mounts and wing doublers for reinforcing the mount area
- Better colour contrast for camouflage paint finish

Maiden was a huge success and I've been flying it regularly since then.
Awesome plane!

Background info:
I have recently bought nolimitdronez mod software trying to remove the maximum height limit of my Mavic. Downgraded from V01.04.0400 to V01.03.0900 in order to get the height limit removed. Planning to test the limits in the countryside of course. However, the firmware of the controller is on V01.04.0400 and has not been touched. I'm was using the MODDED DJI GO APP (For the first time). https://sparkpilots.com/threads/dji-...r-4-1-15.3841/

Before crash:
I was flying my Mavic on a grass field 100 meters away from a tall building to take a look. Everything was working normally and suddenly the motor stopped working or a prop flew off or something. The aircraft started spiraling down, I tried to restart the motors with success but according to the log file my Mavic fell even faster after the attempted motor restart.

My Suspection:
I either lost a prop in flight or it was the MOD that caused it. However, I would like to know the exact cause.
I have checked the log file and there are quite a few errors. Such as MOTOR IDLE, GPS POSITION NO MATCH, there was also missing data for 16s right before the motor went out.


Note: NO ONE WAS INJURIED! My Mavic crashed on a grass field and there was no one around(Except for me). Fell 2 meters away from me. Definitely scared the crap out of me

Zip file attached includes the DAT log file, TXT log file, and xlsx file converted from the TXT log file.

Thanks in advance for the community's help!
