My winter project just completed - I took a Fly Fly 90 MM Hawk and did some modifications to make it more scale and covered it with
FOAM-TAC'S Fiberglass cloth and There Foam Finish which is a water based product - which makes not only fiberglassing easy but
with no odors and easy clean up - once the fiber glass was applied I was able to remove a lot of the excess foam - in some parts the
foam was 22-24 mm thick -I was able to thin the foam 6-10 mm without weakening the models structure.
the combination of the light covering and foam removal allowed for a ready to fly jet using a freewing 90 mm fan and 6 s 4000
35 c lipo with a ready to fly weight of 100 oz (2834 grams) the model features electric retracts, flaps, complete lighting system

The E32 came last week , but the weather also turned for the worse with wind gust's up to 100kmh ..
This morning was far better , but still windy .

The E32 is a single cell ( 3.7v or 4.2v Fully charged ) quad with altitude hold , one click landing , headless mode and one click return as well flip capability .
Also there is the WIFI for FPV (?) as well video recording directly to SD card or to your phone VIA the Eachine APP .
Speaking of the app , if you like me find the Google app store a complete PITA (?) , then it's relatively easy to find a direct download .
https://apkpure.com/eachine-mh/com.f...chinemh.sdrone > Direct Download .

With the app installed on your smart device ( phone ) , you can receive video ( Wifi ) and record video .
You need the app to record video , which is annoying . With my Android phone lag spikes are common and 5 or more seconds long making FPV VIA Wifi not really feasible .

Altitude hold : Some quads leap off the ground up to 3 meters when power is applied or you use some form off auto take off . I was pleasantly surprised to find that such was NOT the case with the E32 .. It rises gently off the ground and when you stop giving throttle the quad hold what ever altitude you stopped at .. This is nice as if its really windy outside you can still fly indoors .

One click landing : It really works , it's not a controlled crash as with some quads but an actual landing .

The reverse thrust after touchdown works great with wheeled floats. However I wanted to try the reverse thrust with conventional taildragger gear. To avoid reverse in the air and possible loss of control its recommended the reverse arming switch (Im using the E switch on my iX12/DX9) only be activated after touchdown. The ESC directions recommend using reverse only when the prop stops turning. So I activated the prop brake following the ESC programming directions. After closing the throttle the prop does not windmill but stops turning in about 1-2 seconds. The stopping distance is greatly reduced without the use of wheel brakes and without the risk of nose overs and prop strike damage.

From flghtengr post.
Key is to make sure rates are set to High before switching the desired switch so it is assigned.

SAFE Select
The SAFE Select receivers behave like normal AR636 receivers for the most part. Rather than having three SAFE flight modes, there are only two modes - "SAFE on" and "SAFE off". When SAFE is on, it has self-level capabilities similar to Beginner Mode on most of the other SAFE receivers. It has the bank angle limits set to a larger angle, similar to Intermediate Mode on the other receivers. When SAFE is off, there are no self-level or bank angle limit features, turning the receiver into a normal AR636 with AS3X.

The transmitter setup is very simple for SAFE Select. First, you start with a normal, default Acro (Airplane) new model. The first 6 channels are set up to control the plane directly. If the plane has flaps, they should be connected to channel 6 (Aux1) to work with the transmitter's built-in flap system. If you have an additional feature on your plane such as retracts, that would go on channel 5 (Gear).

You can choose whether SAFE is on or off permanently during the bind process. If you bind your transmitter to the receiver in the typical way, SAFE will be off. If you change up the order of the last two steps, you can bind with SAFE turned on.

Bind with SAFE off:
Insert bind plug in receiver.
Power up plane/receiver.

Hey all,
Have my first setup planned out, but haven't flown FPV before and i wanted to be sure i have everything i need, so i thought i'd post my list.
I'm pretty good at LOS and i've flown a sim for a while

Diatone gt-m3 - figured i could lower the rates a bit until i feel confident on it
https://www.banggood.com/Diatone-201...l?rmmds=search

spektrum dx6 - already have it
https://www.horizonhobby.com/product...ode-2-spmr6750

longbow mini dsm receiver - only one i've found that fits, if anyone has a recommendation for a longer range receiver that fits i would love to hear it!
http://graysonhobby.com/longbow-mini...-drone-rx.html

Eachine VR D2 Pro goggles - on sale right now, any recommendations for boosting range with vtx?

The Patch Antenna For DJI Cendence Remote Controller











Since receiving the DJI Cendence I have seen the question time and time again asking is it worth using the DJI Patch antenna compared to the standard omnidirectional sticks and what benefit does the patch antenna give. Because of this I decided to do some tests to try and show the difference between them and see what was one was actually better to use as well as get some data on how directive the patch is as well.

For more info on the Cendence remote or the Inspire 2 or to order see
DJI Cendence http://click.dji.com/ABwjVqd-Sl9O9-w...0012&pm=custom



A Closer Look at the Patch





As you can see the patch is not just a simple passive antenna, while it has 2 RF connection it also is connected to the CAN port on the Cendence remote, because of this something to note is that the patch antenna also has firmware onboard and its important you update it when you update the remote, this is easily done by connecting the antenna to the remote before you update via DJI Go 4 or the Pilot App.











Looking inside the antenna it’s self you will find there are 2 identical PCB antennas, these are backed by a screening sheet with the logic controller board mounted in the middle. its important to ensure you have the antenna facing the correct direction as this screening sheet at the rear will block all signal from getting through so the antenna should be mounted with the smooth flat face pointing forward

Just finished my 1/4 scale, 1933 Pietenpol Aircamper. It started as a vintage, House of Balsa "in the bones" project that I got from my good friend Billy. I saw a lot of potential in it, so I decided to take on the challenge of finishing it. I covered it in Ceconite, pinked & stitched it all (with Poly Brush), and filled the weave with water based Polyurethane. I then finished it all off with Rustoleum rattle cans. I've got a OS Max .91 four stroke hiding under that balsa 4 banger! The air for cooling flows through the "fake" oil cooler mounted on the front of the "engine" & out through the empty rear of it. Here's some pics:

In case you were wondering where I came up with those cool little "spark plugs"...........there just wood dowels, turned down on my lathe, painted white, striped, laying a brush down against the white while turning in my lathe, all in with a drilled out lock nut, finished off with a miniature brass stud & nut. Pretty convincing, huh? Building the "woody" 4 banger was actually more fun than the plane!...Continue Reading

First quick test and edit of my first video footage of the super fast XJB 145 flying around a bike track and filmed with a Quelima SQ12 HD Camera. I am sure I didn't get to 100mph but it sure did feel like it! Boy, this drone is fast and definitely an upgrade from the ViFly R130.

💨 100 MPH 💨 Quelima HD Camera Bike Trail Speed Test with XJB 145 drone under 250 grams (Adobe Edit) (2 min 5 sec)


The Quelima SQ12 HD footage is not bad for 30fps although there are some dropped frames and a black sun due to the cheap processor but for 10 it's not a bad camera.

I think the XJB 145 deserves a runcam split mini but the frame may need to be changed first. The Quelima SQ13 and Hawkeye Firefly are in the same category as the SQ12 so they are not worth the extra bucks in my opinion.

Music: Mixes by Gramatix

Equipment used: HGLRC XJB 145 Drone under 250 grams https://www.banggood.com/HGLRC-XJB-14...
Quelima SQ12 HD Camera (like the Hawkeye FireFly Micro Camera) https://www.gearbest.com/automobiles-... (the Quelima SQ13 like the FireFly is out now on GearBest
Jumper T8SG https://www.gearbest.com/radios-recei... Original SQ12 footage modified using Adobe Premier Pro editor Betaflight 3.2

How to update or remove the date/time stamp on the Quelima SQ12: The camera will write a text-file to the sd card (20150101235530 / yyyymmddhhmmss) that can be corrected with a text editor. If you don't want the date timestamp to appear on your video simply change 'Y' to 'N' (No) and save to sd card.

The new S1 Pentium from JJRC is one of the mini self righting boats in their S series which includes three very affordable 14 inch boats of different styles. The S1 is currently available for only $36.99 Click me to order.

The Pentium with its red, and white color scheme, immediately jumped out at me as a great looking little boat for running in pools, ponds, and other small bodies of water.

These little water cooled boats are powered by a 370 motor, and a 7.4v 600mah LiIo battery. They have fully digital proportional throttle, and steering, and the steering duties are handled by a micro 3 wire servo. As the title suggests these boats are also self righting, so there is no need to rescue a capsized vessel. Simply apply a quick blip of forward to reverse throttle, and the boat will roll itself upright, ready for more action.

All three models, S1, S2, and S3 are complete ready to run packages, that include everything needed to run your boat, except for 4 AA batteries for the radio transmitter. For safety, these boats also feature a low battery warning beep, and a weak signal warning beep that sends the warning back to the radio so that you know when you're getting out of range, or the battery is getting low.

Check out the pictures, and videos. Please don't hesitate to ask any questions. Stay tuned for running video coming soon.

Happy Boating!!

Hello & Good Day to All!

I badly need your help how to trace the problem in my power supply HP ESP135 Model: PS-3601-1C. The status is like totally dead but the 2 power capacitors are getting voltage of 300VDC. Shorting the output pins 6,8,10 in this case does not help.

Anybody has a good knowledge about this power supply? I need the Schematic Diagram please?

Thank You and Best Regards,

Picked up a cheap 250 CFX that needed a bit of a going through. Motor had tired bearings and squealed like hell in idle up and several other little gremlins tweaked feathering shaft, slight tweak in the tail tube and sloppy feathering shaft bushes. Chassis / servos / canopy all mint.

Motor - ran okay just sounded terrible in idle up, had a high pitched squeal out it went, pulled it down and yup both bearings notchy as hell and showing signs of wear on the shaft - time for a replacement.

In with a Turnigy 2627 - 4200kv. went up one size on the pinion - 13t to counter the minor drop in Kv value 4500/4200 x 12t = 13t and went with a steel lynx gear - nice. The Turnigy motor comes in a nice plastic case with plug ends, shrink-wrap and a spare main shaft and a couple of 0.5M pinions - 11 and 9t.

Initial run up was nice, then down the park and the main motor esc gave up....... this is the third blade 2 in 1 I've had smoke the main motor circuit, had a 200 SRX go, then my 230S went out and now this one in the 250 CFX. No warning fine one minute - stop the next and the ESC is smoking hot......... I'm figuring they are crappola quality wise in the main motor circuit components........

Another aspect I really hate in the 230 and the 250 is the mule kick these esc give on start up. this is why so many people have hassles with these things tipping over on spool up.......... I did my own 2 esc...Continue Reading
