iFlight iX5 and Thor Loki carbon frames

Recently I have finished a build based on Omnibus F4 Pro and Racerstar 33A 4in1 ESCs. I have flown it three times and the FC stopped working so I had to replace it and since it was clone I have bought the original Omnibus from a friend. After that I have had some problems with ESC desyncs and I have managed to break my X-Foot frame, so instead of ordering another one, since I started to suspect that this will be a problematic build, I have started looking for affordable 200-210mm carbon frames with 4-5mm thick base plate.

After doing some research I have ordered one Loki V1 with 5mm base plate and one V2  with T700 carbon. The V1 one arrived sooner than the other so I have moved everything on this frame. These frames are versatile and could be used both for racing and freestyle. The battery can be placed on the bottom and on the top depending on your style of flying.

Loki V1

THOR210 Loki (nevermind the naming)

This frame costs $30 on Aliexpress. The baseplate is 5mm thick and the top plate is 2mm thick and the overall weight is around 90 grams with hardware.
I have read that some people complain that the carbon isn’t stiff enough and it bends on crashes and I can confirm that this is true, since I have managed to slightly bend one of the arms without breaking it. After that I was able to straighten it up and I have reinforced the arms side walls with super glue which made the arms stiffer.
Overall I’m satisfied with this frame but if I should decide between this one and the V2, I would get the V2

THOR V2 Loki

This is upgraded version of the V1, it costs around $36, it is a bit lighter,  82 grams it has titanium screws and it is made of T700 high quality carbon. The bottom plate has recessed bolt holes. The kit also includes camera side plates. I haven’t got my hands on this one, since I’m still waiting it to arrive, but I will update this post with my findings as soon as I got it.

iFlight iX5 V2

iFlight has been producing a high quality frames for a affordable price for quite a while now. They have several versions of the iX5 based on the build material: carbon fiber, carbon fiber composite and carbon and molding composite material. The overall frame geometry is similar to the Thor frames. The carbon fiber costs $35 and it weights 85 grams, the baseplate is made from 4mm carbon fiber and 2mm top plate. Be aware that this frame uses 28mm standoffs and some cameras may not fit in.

When ordering from iFlight website you have the ability to choose and combine it with additional accessories.
Overall this is really high quality carbon frame that is widely used as a goto frame for cheaper builds. A lot of pilots are flying rigs based on this frame that are around 250 grams range.

The composite version – iFlight RACER iX5S costs $34 and it is based on composite material and 3K carbon sandwich. This combination provides a very light frame 66.7 grams and doesn’t sacrifice the overall toughness. The composite material seems to be balsa wood as stated in the product description.

The molded composite material version – iFlight Ultimate iX5 costs $35 and is similar to the one above with one difference that the carbon fiber sheets are molded around the balsa instead of sandwiched

Let me know your thoughts, what is your favorite carbon frame?

Racerstar Star20 4 in 1 ESC

Star20 is the newest 4 in 1 ESC from Racerstar that for the first time offers a unique feature, each ESC is detachable.

I saw this item posted on BangGood and it seemed like a nice logical step forward in the 4 in 1 ESC development so I have decided to take a look and share my thoughts.
This is the long awaited feature for all fpv miniquad racers that are flying 4 in 1 ESC combos on their rigs either they want to have a clean build or they have some of the newer airflow optimized frames with thin arms.

I have seen several burned 4 in 1 ESCs and most of the times nobody cares to repair them so you have to throw it in the garbage even if only one FET is burned. They are a bit cheaper than buying 4 regular ESCs but it seems a waste of money throwing three working ESCs when only one is burned.

4 in 1 ESC separatedThis item is on preorder at the moment and looking at the photos, I’m not sure if the ESCs come soldered or separated (they probably packed with shrink tube). Either way, if they are separated it will be required to put a few blobs of solder in order to connect them and there is no delicate soldering required.
I think that this is the first 4 in 1 ESC of its kind and probably more will follow.

At this moment it is few bucks cheaper ($29.99+$0.34)than regular 4 in 1 20A ESC listed on BangGood from the same company.

I’m considering buying one of these since I’m planning a new build based on the X-Foot frame, but maybe I will have to wait for Racerstar to release Star30 30A 4 in 1 ESC in order to use it with some of the new powerhouse motors that are available on the market lately.

Update: It seems that FPV Model is already offering similar product X-Racer Quadrant 25A and it is in stock at the moment. The only downside is that this one is a bit longer so it may partially protrude out of the frame.

Revisit with my ZMR 250

I have kept my battery packs full, waiting for the right moment to go and fly at the same spot that we have visited few days ago. I have been using ZMR250 and mobius for aerial photography for quite a while. I love the portability of the ZMR250, everything fits in a really small backpack and that enables me to reach most remote places.

It was raining most of the day, but it suddenly stopped and the sun came up so I have grabbed my gear and rushed to just in time to see the sunset.

I have decided to fly at two locations that were close enough to fly from one spot to the other but in order to save battery life I flew one pack at the first spot and then moved to the other one.

Ohrid lake aerial photography

Although most of the people doesn’t like the fish-eye distortion these small wide angle cameras produce, I have found that sometimes the effect could look really interesting when used for aerial photography.

It was windy, but nothing that my miniquad could handle. You could see how much I had to lean it to the wind in order to counteract its force.

The boat was still there, at the same place. This time, I have decided to take some photos from another angle since I liked the colors of the sky reflecting in the lake.
