When thinking about the pros and cons of vertical arms this idea striked my mind: Combine vertical and horizontal arms to form a T-Beam. I started designing a frame for a 4" ultralight (<250g all-up-weight) with easily interchangable arms, minimal weight and maximal durabiliy in mind. Ok, fair enough, this is probably the goal for most frames out there, but I think this approach is pretty different and I'm quite happy with how it turned out! The T-Beams give the frame an incredible amout of stiffnes and good durability, especially considering the weight of only 33g. And most importantly the design is completely open-source, you can take a look here. Edit: I just realized you need to create an account to watch it :/ But it's worth it

This frame allows you to build a Quadcopter with 1407 Motors, 20x20mm Stack, Micro-Camera and a 4S 800-850mAh Battery under 250g AUW! It has an insane amount of power and feels really agile in the air. I used the Rotorgeeks motors and HQ 4x4.3x3 V1S. This is a perfect combination I think and those props are just awesome.

A few notes about the design.
-The T-Beams should be glued into the arm with epoxy
-The Top-Plate is held in place by rubber bands/big O-Rings using eiter the hooks on top or a little furter down. Initially I used long screws which went alls the way through the frame but then dropped this idea because it was just not practical. However, if you like to, you can just load version 0.10c in Onshape. I also attached...Continue Reading

I always like to see what kind of power my planes make. The BAe makes some impressive numbers.

This is my Blade Scimitar 110 FPV Quad BNF Basic FPV Maiden Flight.

Blade Scimitar 110 FPV Quad BNF Basic FPV Maiden Flight (5 min 3 sec)

Blade FPV Quad Review Notes:

Pros:
- Runs on 2S or 3S lipo packs
- Comes professionally pre-tuned out of the box
- Includes spare props and prop tool
- It is easy to setup with the manual
- There are different VTX power settings
- You can program the VTX settings with your radio or by pushing the button on the quad.
- The video quality is great via my Fatsharks
- It had a price reduction recently, so the price is only slightly more than the Blade Torrent 110 FPV Quad at the time I made this video.

Cons:
- There are only three camera angle settings separated by 15 degrees with a maximum angle of 30 degrees
- The antenna pops out and moves side to side way too easy. I may be modding that with rubber tubing or hot glue.

Got the purple Robocat back together, and flashed with Ardupilot. If it ever stops raining, will take it for a test flight.

It was a beautiful day in the Netherlands.
Today the Chica had his maiden flight. For this i get some help from TvM. After the trims are set, i got the controles.
It is a bit exciting, but the Chica flies well. See the photo of the Chica.
Now i can think what will be the next project.

Thrust bearing detail.

The start of the running gear. The stainless steel rod was smaller than the hole in the propeller.
Flattened it out a bit, and threaded it. Added some silver solder to hold in place. Made a thrust bearing washer from a hard nylon type material servo arm.

After almost exclusively flying 5in and 6in quads for the past few years and being disappointed by the power of early brushed whoops, I was finally convinced to try out a brushless whoop that I have been hearing a lot of good things about, the Happymodel Mobula 7. I’m not a fan of large walls of text, so I’m going to try to keep this concise. I’ll talk a bit about my thoughts and observations after 20 flights, then setup and modifications.

Initial Thoughts:



The box has a sticker on it that says Jan 23rd, 2019, which I assume is the production date.
My unit came with an F3 flight controller (stm32f303), though there are others who claimed that theirs came with an F4 flight controller, so you may be luckier than me

Sommer is here and I got some new stuff including a second CrossFire TX (the micro one this time) to play with and when I heard how awesome the new Diatone 3inc PNP R349 is, I had to snag one for myself



Like always I wasn't happy with going the easy rout... I had to add CrossFire and a nice vTx antenna (I did not go for the Unify version for no reason ) and change to #ReversedPropDirection before going for maiden.

About 9 months ago, we started TMac FPV YT channel to document our "Journey to Better" FPV Fun, Flights, and Racing Stuff and share our flight footage and stuff we learn with our family & friends. Within the past week, we have surpassed 100 subscribers! This, to me, is a humbling experience. I am very appreciative of the support from our "TMac FPV Teammates" and want to thank you in some way for that support.

So, we've put together a Micro FPV Build "starter kit" as a Gratitude Giveaway. At least one of the components we're giving away can be used in ANY size Quad, so, if interested go ahead and check it out. It's Free! Once again, Thank You to All! Enjoy & Happy Flying!
