The iHobby 1/24 MT review

I’ve always enjoyed sharing my hobby with others- when they pick up the transmitter and understand why grown men play with toy cars (well, at least in my mind they understand) … it’s almost magical. While I do have slower trucks that I trust with beginners, I’ve been looking for something that I don’t have to cringe as much in an inevitable crash.
As physics is the law, it’s time to think small! That’s what sparked my interest in the iHobby Racer. Landbow, the manufacturer, contacted me a couple weeks ago saying that they’ve a new product for me to test out (professionally, I develop R/C products for a US-based company). I really enjoyed testing the truck and asked the manufacturer to provide a production sample for me to do a full review.
Questions, suggestions and comments are welcomed, as always.

*Disclaimer: The truck was provided by Landbow, under the understanding that the review will be unbiased, and that there are no economic gains for me other than the trucks provided for testing. I write these reviews for fun and intend to keep it that way!


Official specs are as follows:

Wheelbase: 125 mm
Ground Clearance: 9 mm
9g 3 wire servo
2-in-1 Speed controller+RX
High-Grip all-terrain tyre : Diameter 42 mm , Width 20 mm
Gear rate : 1: 15.6
Motor type: 180

Fei-Lun has been enjoying a streak of success with their FT line of fast and affordable 2.4GHz boats. While not always known for being the most reliable boats out there, they were easy to work on, easy to run and the self-righting feature was much appreciated by most beginners and experts alike.

When I was doing some pre-review research, I was shocked to find that this boat measures in at 65cm and has a 4S power system. That’s an insane amount of power for something that is not entirely hobby-grade (But I guess it’s less crazy than its predecessor, the FT010, which has a 4S system and brushed motors).
Before we begin, I would like to thank T-Mart for dragging me back into the world of writing reviews, I appreciate that they continue to value my opinion. I hope that you, the reader, would get some useful information out of this review. Please do not hesitate to let me know if you’ve any questions or comments.

From the dock
Like the other boats in the FT line, the FT011 comes with everything (other than the AA batteries) you need to get started. I was quite impressed that they included multiple spare props along with some maintenance tools for the user, nice touch!

1x FT011 boat
1x 2.4GHz Transmitter (Requires 6x “AA” batteries)
1x 4S lipo charger
1x 14.8V 2200mAh 30C Lithium Polymer battery
1x Plastic display stand
1x Rubber nosecone bumper
2x Propeller (spares)
1x Bag of accessories (3x Spare props, 1x Waterproof marine

The FMS 800mm V-Tail (Trainer/Parkflyer) review

Hey guys,
Do you remember what your first trainer aircraft is/was? For me, it was a REALLY ugly 2 channel HiTEC Sky Scooter that was patched up in so many places that I swore it had more epoxy/tape than foam.

A decade later, boy has technology changed the game. T-mart sent me the star of our review today, the V-Tail. In this review, I would like to give you my honest and unbiased opinion on this aircraft, concluding with whether or not I think this aircraft is good for the absolute beginner.

Before we begin, I would like to thank T-mart for providing the sample and agreeing to an unbiased review. Their support is much appreciated.

From The Box
The aircraft came well protected in the Styrofoam box

Included is the following:
1x 2.4GHz 4 channel transmitter
1x 800mm V-tail glider
1x Linkage set (packaged with glue and a spare wing bolt)
1x 7.4V 350mAh 15c Lipo
1x charger (no adapter though!)

Note that this is a work in progress, since I am interning at a hospital, my work hours are quite strange compared to that of the gf's or my cameraman, Nutta. So I'll find time for them to help me make a flight video when possible. Bear with me please! I've tested the quad extensively though, so here's the review in it's current form:


Hey everyone,
After much anticipation, my RC EYE One from RC Logger has finally arrived! I was supposed to receive it long ago but it was stuck at the customs office due to a month-long ban on R/C products (Politics, sigh). Anyways, it has arrived and here is what hopefully is an unbiased and helpful review about the RC EYE One. Before we start the main part of the review though, I would like to thank RC Logger (Chris, Tracy, Doris and Adam in particular) for providing the sample and sending it all the way to Beijing. Although they are representing the manufacturer, they have asked me on numerous occasions to make sure that the review is unbiased (as always). Oh, and I want to point out that I rarely see any company in the industry (or in other industries even) that do customer support/service as well as they do. They are a very professional team and dealing with them is a pleasure!

From the box
The RC EYE One came well packaged in a very compact and well designed box...no wasted space at all.. it reminds me of the boxes that other consumer electronics come in. The contents are well protected and

Hey guys,
I've been really busy lately with work at the hospital and writing reviews has been taking up quite a bit of what's left of my spare time
So, in order to increase my efficiency, I would like to ask you guys which products you would like to see reviewed. Due to the space (or lack thereof) I have, the biggest helis/quads I can review are around 250 sized...and fixed wing aircraft are unfortunately out of the question. 4 channel and up preferred

Cheers in advance for the comments!

So here's something different- a blog entry that has (mostly) nothing to do with R/C!

It's the national holidays here in China and bored out of my mind, I asked Nutta to take a road trip with me to the China Aviation Museum out in the suburbs of Beijing (about 2 hours by E-bike+Subway+Bus). I've been to this museum a few years ago but it was more like an aircraft graveyard than a museum. They renovated the whole museum a year or two ago and I decided that as an aviation enthusiast, it is my duty to go and visit these great aircraft again.

So after mucking about with my quad til' 4 in the morning, I woke up at 8 to finish my work, packed my quads (promised the guys on the mini multicopters thread that I'd fly the quads among migs and make a video)and we left around 9. It took us quite a while to get there but chatting with one of my closest friends and smooth public transport transfers (I know...when does THAT happen) really made the time fly.

As soon as we entered the museum (after a VERY long walk from the bus stop to the entrance), I went into kid-in-a-candy store mode. Famous aircraft like the Vickers Viscount, the DC3/C47 and Li2 loomed into view... all professionally repainted and polished... a thing of beauty if I ever saw one.

After this came "the cave", which holds many interesting and historic aircraft... I am searching online on the origins of these aircraft since I have no idea how they got there... a T28 Trojan in it's Navy colors, a ROCAF F5 (...Continue Reading

Hubsan X4 Review

The Hubsan X4 is the smallest quadcopter currently available in the ready-to-fly form. There was a lot of excitement when we first saw its aerodynamic canopy... “sexy” was used to describe it by many and I certainly agree. Talks about it haven't stopped since, and with the arrival of Banggood's first batch of 30 aircraft (28 for the customers and 2 test units), people will hopefully start receiving them soon. This review is written for the purpose of helping potential buyers decide if the Hubsan X4 is a worthy addition to their fleet.

Size: 60 x 60mm
Motor (x4): Coreless Motor
Frequency: 2.4GHz
Voltage: 3.7V
Battery: 240mAh Li-Po Battery
Flight time: above 9 minutes
Charging time:30 minutes
***Features a 6 axis system with adjustable sensitivity***

I could still vividly remember the first time I flew the QR Ladybird… because I could not wrap my head around the concept of such a small, simple aircraft with such amazing performance. Many quads have entered and left my fleet since then, some I liked and some I didn’t…but the QR Ladybird has always occupied a special place in my house: right by the door where I could pick it up and go.

Although the market has recently been flooded with a wave of clones, I still maintain that the best flying quad of it’s size is the QR Ladybird, and if it was priced lower…I believe that everyone would have one instead of flying one of the clones.

That brings us to the star of this review, the QR Ladybird V2 from Walkera. It is a stripped down version of the V1 that comes exclusively as a RTF set. Priced at around 60USD ready to fly, it is a bit more expensive than the clones, but much more affordable than the original V1 (that come in at around 75USD BNF.)

Introduction (and a few words from James)
Hey everyone, I know that I've promised a review of the X100 a few weeks ago...but I've been so busy lately that I can barely find the time to do my paperwork at the hospital... let alone the review! (For those of you who are following my exciting life at the bottom of the medical pyramid, I'm doing my rotation in the Internal Medicine/Cardiology ward... not a fun place to be for both patient and doctor )

Anyways, I trust that many of you have seen Erdnuckle's excellent post on his blog about this quad...so I hope that my findings can provide another point of view or further information perhaps...into the performance and many other aspects of this great little aircraft.

Special thanks goes to Banggood (my friend Aaron especially) for providing the sample... and to you guys for reading it.
As always, questions and comments are welcome and much appreciated.

From the box

There was no damage to the box at all when it arrived at my apartment (although it has made a far shorter journey than most). Like Erdnuckle said though, everything from the box to the manual were in Chinese...which may be a problem for most of you. In the following review I'll label most of the buttons on the transmitter and highlight some of the unique functions of this quad, so hopefully the lack of an English manual won't be too much of a problem for you guys.

I've been reflecting on how my life has changed dramatically since I found r/c as a hobby back in 2003.. and my conclusion is that it's not the aircraft, but the people that have made the greatest impact in my life. I would've given up very early on (those were the days of nicad batteries and 370 brushed motors after-all!) had it not been for the patience and kindness of fellow hobbyists... like Mr. Wang, who offered to teach me how to fly when I came up to ask questions about his Tigermoth and Formosa (Now he's a very close family friend) or the flyers at El Toro, at Northwood Highschool in Irvine, at ShinKong park in Taiwan among others.
I really think that those who share our hobby have a passion, a flame that should not be hidden but one that should spread like wildfire. Share that love of flying to others... you never know, it might be someone's life you're changing the next time you head to your flying field!

Although most of them probably won't see this message, I'd like to express my heartfelt thanks... without people like them all over the world, the R/C community be what it is now.

I am deeply addicted...almost ten years in and it seems that the addiction will only get worse. Bring it on!

"When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been and there you will always long to return."

What are your stories?

The Benma Helios 100 Review


A few months ago I was approached by Benma and they asked me to give a few opinions and join the development of a brand new 4 channel helicopter. Their aim was quite high...they wanted to make the cheapest yet best performing 4 channel (flybarred) FP helicopter. Impossible? That's what I thought too...

Benma's prototype seemed to confirm my fears... the gyro, the motor and the flight performance in general weren't up to par with the V911... I was quite disappointed. Many of you have seen this thread by then and some have even pre-ordered the aircraft... yet since this first batch of aircraft did not perform as expected, Benma recalled them. (It actually was sent to vendors like Banggood already) and re-designed the software and a few hardware components too.

Fast forward to a few days ago. My friend Aaron from BG told me with great excitement that he got the production version of the Helios and that it was much better. I was skeptical... but he's quite passionate about R/C as well so I knew he wouldn't tell me something's good unless it really was.

Today, a package arrived for me at the leasing office while I was at work... It was the Helios 100... I can't tell you how excited I was to see the complete version of this thing as I spent a lot of time relaying our ideas on the forum to Benma.... the name and the little sun on the tail were my personal touches too...it's amazing to see something that you did...Continue Reading

Introduction (and a little bit of history)
Ever since I saw a replica of the Horten Ho229 in the San Diego Air and Space Museum, the story of the Horten brothers and their flying wings has always fascinated me. When the most advanced aircraft of it's time were piston pounding Spitfires and ME109s, the Luftwaffe's requirement of building a fighter-bomber that flies at 1000km/h, carries 1000kg worth of bombs and has a range of 1000km must have brought along a few dismissive chuckles. Yet the Horten brothers came up with the Ho229, a turbojet powered flying wing that met exactly those requirements. World War II would end before the aircraft ever saw mass production or service though, and the aircraft was slowly forgotten in the history books. After World War II, Northrop evaluated the Ho229 and some of what was learned was used in the eventual development of the B2 spirit, the most advanced bomber in the USAF arsenal.
The Hoten-X from Walkera seems to be a stylized nod to the Horten brothers and their work...Although it's a r/c quad-copter and not a flying wing, the futuristic, out-of-this-world lines of the Ho229 are still reflected in the quad's canopy. You can probably imagine then, how excited I was when Aaron from Banggood asked me to review this quadcopter. I hope you will enjoy this review...and if it sparks your interest, I would really recommend that you watch the NGC documentary “Hitler's stealth fighter”.

My review items- the Hoten-X and the mini pet!...Continue Reading

Quads have become increasingly popular lately with the introduction of relatively cheap models such as the mQx and the Ladybird (I own one and it's absolutely amazing), but the WLToys Beetle is the first toy-grade quadcopter that may make it to malls instead of hobby shops.
The Beetle is a clone of the mQx, at least on the design of the frame and motor/gear/rotor assemblies... but the rx board itself seems to be a different design to the original, and it doesn't have the capability of flying in + mode like the mQx.
Anyways, you can imagine how overjoyed I was to see a big cardboard box sitting at home because I knew exactly what was inside

*Disclaimer: The WLToys Beetle review was written on June 13th, 2012... the sample is a pre-production model and was sent for flight performance review purposes. The performance of the final product may be different as WLToys modify their product but as always, you can trust that my findings are accurately reflected in the review that you are about to read.


Inside the package that I received is the RTF version of the WLToys Beetle. Contents of the box include the following:
1x WLToys Beetle quad
1x 3.7V 500mah battery
1x Lipo battery charger
1x 4...Continue Reading

Questions/Comments: Please PM JamesChen072


============================Original review below============================================

Hey all,
Recently a neighbor saw me flying my V200 and asked me to teach him how to fly... and my gf wanted to try out single rotor helis as well (she began flying coax helis a few months ago). Unfortunately my Solo Pro and Bravo SX simultaneously developed problems with their receiver boards...SO I decided to purchase a rugged trainer to add to my ever growing fleet...
Living in China has it's benefits.. the water and food might not be the best in the world(i miss the food back home)..but flying is much cheaper here than it is in the States ...I ran across the V911 about a week ago and decided to buy it because of it's low cost (30usd) and interesting design(solo pro mated with a Trex100)...

-On the tarmac-

It arrived last night after much anticipation... The V911 was very well packaged and had a lot of extras including a spare main and tail blade set, USB dual battery charger and 2 batteries! I couldnt wait to fly it but I promised to give

Hey guys,
I was contacted not long ago by one of Lightake.com's staff, Mr. Zhou, who asked me to do a review and possibly select products for them to sell (They are starting to focus their efforts on hobby grade products). I picked the Mini CP, the QR Ladybird and the star of this review, the Super FP. Not much needs to be said about the Mini CP and the Ladybird... They are well known and have their own dedicated threads which provide great info for owners and shoppers alike.

This review was written on May 7th, 2012. Information regarding this helicopter may change as Walkera improves the receiver and parts... but you can trust that, although this sample was provided by a company, I am completely honest in the review and I am receiving no financial compensation (besides the sample itself.) So feel free to discuss every aspect (Good and bad) of this helicopter in this thread. Still feel unsure if this helicopter is right for you? PM me and I'll try to analyze your situation for you, if I have time.


The Walkera Super FP is the newest member of a new generation of Micro flybarless fixed-pitch helicopters, like the Blade MsrX and the Walkera V120D01. Utilizing 3 axis gyros, these helicopters are great for beginners because of their simple rotor structure, efficiency and stable-yet-maneuverable flight performance. These flybarless fixed pitched birds sure have come a long way since the still relatively recent Solo Pro, MSR,...Continue Reading
