Another two-pack session at the RC field, with more power loops (one around a tree!):

FPV progress - flight #4 (4 min 57 sec)


TIL:
  • 0:00 Betaflight OSD is awesome and tells you what's wrong before you can arm
  • 0:12 Center your trims as part of the pre-flight checks, or disable them completely. Quad constantly pitches backwards right from the start (see 0:12) and I thought it's my FC drifting.
  • 0:25 It's never too late to switch on airmode!
  • 0:38 Previously I was cutting throttle rather early in a power loop. This one looks better than before and actually goes backwards at the top. I figured it makes sense to cut throttle when the horizon comes back into view from the top, and that helped a lot.
  • 0:49 my turns are ugly.
  • 1:00 a power loop with crosswind not ending where it started
  • 1:46 Quad, meet nemesis tree - nemesis tree, this is quad. You'll have an awesome time together. This first attempt went well - again with crosswind having a negative impact on the overall result - but a later one ended with an Rx failsafe, and a somersault at the end of pack #5 was too optimistic. Video breakup wasn't unexpected at 160 m distance, so no reason to panic.
  • 3:01 knife edge - yup! I need a place with a suitable gap to make use of this...
And that's about it for this one.

I forgot to switch on the DVR for most of pack #5, but had an Rx loss under the tree and also hit the tree in a somersault attempt. Here's the footage:

Today's Test - Even worse.... seems the FC is getting worse every flight.

2019 0818 RAW BetaFPV HX100 Yaw/Roll Wash Out Issue GETTING WORSE (3 min 40 sec)

Hi, I was wondering if anyone can help me with this problem. I have a new Mobula 7 v2 that does not bind. I have a Jumper t16 using external rf that will not bind to Mobula. My other quads bind fine with jumper. I am using the proper protocol for frsky d.(spi rx support). I did not flash or change anything in betaflight. The one thing I saw that did not look correct is I have no uart in ports tab. I only have one line and that is USB VCP.
I'm still new with hobby and am struggling on troubleshooting. Thanks

I liked the way the vagabond looked and flew, so i built another one - scaled up 50% to 112" span.

It is covered in doped chiffon over a mylar type film just like my 75" version, only I wanted a red one. The cerise red looked nice on the web so I sent for that. Its not so much red as pink but on the model it looks good and when the sun shines thru the frame on low flypast, you can really appreciate it.

It came out heavier than planned - used old balsa stock which was heavy - and CG came out about 50% with either 2 of 3000 3 cell or a 5000 4 cell lipos. The 3 cell gives about 500W while the 4 cell takes the emax 2826.06 motor up to 700W on a 14 x 6 zinger prop. I fly it on about 400W.

Some photos below with details of the model in the build log here

https://www.rcgroups.com/forums/show...s-design/page3

Photos include one showing breakdown of the wings for transport. 1/4" carbon rods used as joiners, the central ones going thru the fuselage so no rubber bands on show except for thin ones holding on tailplane.

The maiden flight was on a windy morning but I needed a proving flight before going to a flyin. Mick Butler took the video, seen here.

This is my H-King Flycat 70mm EDF Jet Maiden Flight Review.

HobbyKing H-King Flycat 70mm 12-Blade EDF Jet Maiden Flight Review (4 min 37 sec)

Pros:
- The HobbyKing Flycat feels rock solid while handling it
- It has a Beautifully vibrant color scheme
- Lots of power from the 70mm EDF Fan unit
- Rock solid ball link connectors
- Quick and easy assembly and radio setup
- Optional Retracts via foam cutouts
- It takes the same batteries I use in my E-flite Viper

Cons:
- No RC Plane lights
- Any plane that requires glue gets a con from me, but it really was very easy & intuitive.

The EC1500 is the best engineered foamy I have had. The parts fit perfectly and it all works. Total time for unboxing and programming took me just over 3.5 hrs. Here are some notes:

The ESC has a blue EC5 (90 amp) connector. The Addendum recommends an adapter. I already had an adapter to convert the EC5 to an XT 90 yellow plug to mate with a 4000 65C Graphene Turnigy pack with a black XT 90 connector.

I used a blank model in the the Acro type and named it EC1500. I used an extension bind cable and used forceps to insert it into the 636 receiver port. After inserting the bind plug and plugging in the 4S pack I did not get a blinking LED on the receiver. I pushed in the connectors to the separate BEC and got a blue light on the BEC and flashing RX LED. I checked all the other plug connections to make sure they were seated correctly. I removed the bind plug and bound my DX9 TX to the RX. It bound standing 5 ft away and I could see the plastic elevator “stubs” move full up when I put the fuselage down into a dive. The ramp/door opened up and was hitting my fuselage stooge. I found out that the default switch is A. Position 1 is open and 0 is closed. So make sure your fuselage holder is clear of the ramp. I later put the Ramp/door switch on switch C (Chan 5) and set the speed to 3 seconds for 0 /up, 1 level, and 2 down. Custom voice for position 0 is “Door Closed”. Position 1 is “Door Open”. Position 2 is “Bombs Away”. NOTE: The Airforc/Coast Guard...Continue Reading
