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?

New RacerStar BR2406S 2300/2600KV and BR2307S 2200/2500KV Fire edition available on Banggood

If you are in for really cheap motors I’m sure that you are already familiar with RacerStar’s BR series which although have relatively low-quality components, they have established themselves as great motors for training and a must for every cheap build.

I have been flying BR2306S 2700KV on one of my rigs for quite a while and I think that they are great motors for the price, although two of them came with considerable play in the bearings that wasn’t affecting the flight characteristics. I have also managed to bend two axles in a hard crash on a concrete but for an $8 motor I have just replaced them and continued flying.

My rig with BR2306 2700 it is not the lightest build but I was happy with the result when I have put it together.

 

A few days ago RacerStar released two new types of motors BR2406 and BR2307  in the same price range. You will get 4X BR2406S for $36 and $X BR2307S for $35 on Banggood

RacerStar 2406 2600KV RacerStar 2307 2500KV

Here are some specs:

Battery: 2-4S lipo battery
Item name: Fire Edition BR2307S 2500KV motor

RPM/V: 2500KV
Height: 34mm
Width: 28.5mm
Shaft diameter: M5
Motor mount hole size: M3

I have already ordered the BR2307S 2500KV and BR2406S 2600KV and I will be reviewing them as soon as have them.
At the moment there aren’t any reviews on these motors but I would expect either miniquadtestbench.com or EngineerX  to have them soon for a review.

They are not as durable as the pricier motors, but for the price, you could replace them much often. Plenty of times I hear people replacing the stock bearings with a high-quality  EZO, original NMB or even Fushi brand from AliExpress. This means that you will invest a bit more money in them and the overall price will get closer to AOKFLY or RCX motors.

It would be good for RacerStar to release spare parts for these motors soon so we could order some spare parts in the same order when ordering the motors.

Hobbywing XRotor Micro 40A 2-5S 4 in 1 BLHeli_S DShot600 Ready

Hobbywing is a long time player on the market of top-notch ESCs and finally, they have come up with a 4 in 1 40 amp DShot600 ready ESC with a current sensor and support for up to 5S voltage.

To be honest, if I had seen this ESC half year ago I would have been asking myself why 40A, but as the things are developing we may need batteries with double C rating then the ones that are already on the market, especially for motors like BrotherHobby Avenger

The build quality is up to the Hobbywing standards. They are using EMF8BB21F16G MCUs with the operating frequency of up to 48MHz. The motor soldering pads are neatly placed on the board and not protruding from the sides as on the Racerstar 4 in 1 ESCs which from other side means that you may need a bit longer motor wires compared to the other ESCs but I don’t think that may be a problem on builds that are up to 210mm. Sometimes even on them if you are unlucky enough you may have to extend the motor wires for motors like Racerstar BR2306S that are almost suitable on 210mm frame (one of the wires could reach the soldering pads, but you will have to extend the other two). There is a dedicated connector for Hobbywing XRotor Omnibus F4 Flight Controller which means far less soldering, you will have to solder the video in and video out wires for the OSD and the SBUS connection wires for your receiver. There is also dedicated type connector on the FC, probably for a VTX, but by the time I’m typing this post it is not out yet and it seems that they will be going the “cube” path too by offering all in one stack.

One thing to note that the ESC could only provide BEC output of 5V for up to 1.5A,  although there are 3.3V, 5.2V and 12V pads on the board they are only for voltage monitoring and they couldn’t provide the load capacity
