I'm really excited for this new product, the Hobbywing Xrotor F4 flight controller and 40a 4in1 esc combo. Hobbywing is the benchmark and industry standard when it comes to speed controller performance and durability. If you look at any serious mini quad motor thrust test results, you will always see the xrotor esc pumping out the best numbers. In the past they were too big to use on mini quads but now they've got their products lined up with current fpv standards.
Even though you may never need 40a capability, it doesn't hurt to have it. From my experience, the bigger the fets and higher amp draw capability usually results in faster responses and better performance as well as durability. In the past I used to run small esc's for the weight savings aspect but with frames and motors getting lighter and lighter, we can run bigger batteries and gear and still have the optimal performance we're all after.

Now with Hobbywings entry into the flight controller market, they made a good decision to go with the F4. Dshot 150/300/600/1200 capable, as well as Multishot/Oneshot42/Oneshot125 and PWM protocols supported. F4 is becoming the new standard now and the coding for the firmwares is beginning to peak at F3 limits so HW is on track with this newest entry into the fc market. Betaflight osd, sd card slot, pin bank to stack directly with the 40a 4in1 esc and Xrotor quality makes this combo a top offering in todays market.

Hobbywing has always been known as a top performer in other RC fields and now they have put down a serious contender in the fpv market. I am looking forward to trying this out and any of there future offerings for fpv!

I just got the DX8 G2 and I've been using the AS3X programmer but it doesn't transfer the D&R Expo settings. The only thing I can see it does is turn on AS3X functionality.

Anybody else having the same problems?

I'm thinking about putting them in the Radio and determining if it works and then again is it safe to fly.

I can't get anyone at Horizon Hobby that really knows the DX8 G2.

I'm really frustrated!?!?!?

The absolute best eclipse movie possible with today's technology would be a realtime 8k in hydrogen alpha. This resolution could reveal individual mountains of the moon overlapping prominences of the sun, without zooming in. The only videos the goo tube comes up with are extremely poor quality. Thus, the lion kingdom expects similarly poor quality of the 2017 eclipse.


Unfortunately, the idea of rigging the servocity to track the sun is not looking good. Testing with the trusty signal generator showed PWM to not be accurate enough. Direct driving the servos with H bridges doesn't look good either. They have to get above stall speed & wait for inertia to slow down. The minimum speed it can step is too fast. These problems didn't happen when using wide lenses, but are deal breakers with the 200mm.

Ok, here we go!

So for the past few planes I've done as TV-VPP, I've been sourcing kits from a variety of places and modifying them to suit. I think this has been a good way to go, as it saved me the time and hassle of painting, as well as all the effort involved in designing and cutting out the parts. Future planes are going to be designed and built from scratch now that I'm seeing reproducable positive results with the TV-VPP setup; previous planes were considered essentially as test beds, and since some didn't last that long, It was probably a wise move. When starting out, I would suggest doing likewise - find yourself a indoor kit with a flying weight of 140-150g or less, and modify it!

First let me discuss the CF hardware I used. The stuff that typically comes with the kit is good for normal flying, but once you start taking the plane backwards and/or modifying the ailerons to be huge, ALL BETS ARE OFF. Taped hinges WILL NOT survive first contact with backwards air, they have a depressing tendancy to peel right off! Also, the forces and stresses that the plane experiences doing these type of maneuvers are often beyond what the planes are designed for, so we have to toughen them up. But, we have to do it smart - that means wherever possible, our additions and modifications need to be weight neutral - that is to say, they dont affect the ultimate flying weight of our plane. For all the hardware we throw away, the new stuff should be the same weight or lighter. Now...Continue Reading

Let me start this off by introducing myself, My name is Scott Brownewell, I'm a resident of NW Indiana and have been flying RC in earnest for about 10 years now. I'm a very infrequent poster on here, but as I've seen some interest in the subject and a general dearth of concise information regarding it, I figured I'd write up some blog posts and share what I've accumulated. When I first saw people flying indoor planes, I was seriously interested. Later, when I first saw people flying very refined versions of those planes backwards and hovering on the nose, I knew that this was something I absolutely had to do.

Fast forward about 5 years of intermittent efforts and about as many failed or half-successful attempts, and I've finally managed to figure it out (mostly) and put together a system that WORKS. Here are some shots of my current plane:

So Ive been into rc's for a few years now but Ive mainly owned off road vehicles and I want to get into on-road cars and possibly buy a roller if not one thats rtr. Ive looked at some models from hpi, team associated, and kyosho but I just wanted to ask what you guys think would be a good model to build and put all my own electronics and whatnot in it. Ill mainly be driving outdoors on just a normal street but i also want to be able to take it to a prepped track and drive there if the occasion arises. Any suggestions?

This is the Performance Flight of my new Eflite FJ-2 Fury BNF Basic.

Eflite FJ-2 Fury 15 DF BNF Basic - Performance Flight (4 min 28 sec)

As some of you may have witnessed the wonderful AstroTurf “airfield” that me and some of my other pilot buddies fly on, it is with some RC aircraft limitations – especially when it comes to DF (ducted fan) style aircraft. The small rubber turf chips of the Astroturf are most likely to get sucked into the intake on any DF aircraft designed with a cheater intake duct or a DF aircraft with a nose wheel “rooster-tailing” the rubber chips right in front of the intake duct on take-offs, damaging the EDF fan blades over time, or worse.. causing a DF lockup / shutdown 6 feet above the ground on take-off and right into the chain link fence perimeter of the airfield – ask me how I know (RIP Freewing F-16 4S Standard). Unfortunately most DF aircraft are designed with the intake just asking for Astroturf rubber chips to be sucked right in like a hungry Dyson vacuum cleaner. It really sucks (pun intended). Now here I am, left with (4) Roaring Top 4S 3700mAh 70C Lipos, and no RC aircraft to use them in.

After some research, I found the now discontinued Eflite FJ-2 Fury. With the intake design ahead of the front landing gear and no cheater intake duct, it was the ideal DF aircraft design for no rubber chips to get sucked in and cause damage to the DF fan blades / internals. The recommended lipo battery for this plane is also a 4S...Continue Reading

I bought a stupid amount of used planes and jets from a friend recently and while I have been able to get a few of them in the air, it is that time of year where I make sure everything gets a little exercise. I don't log how many times I fly, but I do track the dates I fly and do maintenance. Anything that sits for a year gets sold, and I hate doing that. So all those new (to me) planes are on the back-burner for the next month or two.

This time out, the Red Bull Edge was the one that made me wonder why I don't take it out more. It was such a smooth flight and I had a lot of fun with it. I finally put grip tape on the Rare Bear and hand launched it myself. I don't think I will let anyone else launch it for me again because it was so easy and went right up with no dive towards the ground. The Waco has been out with me for the past few weeks because it is new I love it. It just flies in slow motion to me. My son gave the Yuneec Q500 a check up and took some nice video of the field. I had my profile foamy too, but it didn't make it into the pic, which is a shame. After years of practicing and watching others, I did the smoothest and straightest knife edge on it. Of course there was only one other pilot at the club field (besides my son) to see it and it was his first time at the field. I'm always willing to pack a car full of planes to show someone the field and add a new member . I am surprised that no one else was at the club. It was a little hot and I got a touch of sun burn over the two hours I was there, but I had a blast.

Evening all. Looking for some help please.
I have an edge 540 with a 30cc gas engine. It has flown several times without any issues. I went to fly it at the weekend and only while the engine was running my ailerons would move, not like a twitch but more like someone was wiggling the sticks. I've tried offsetting the servos, tried a new y lead but no joy. My receiver is as far away from the ignition system as possible. I am using a 5 cell nicad to power the ignition and another to power the rest,tjese batteries sit on top of each other as I have nowhere else to put them.
Is there anything you can suggest I try next?
Thanks in advance. Jake.

A new design based on military-style cargo planes. Amazingly smooth and easy to fly airplane. Great for a beginning flyer or just a relaxing flying session.



The C-1 Arrives (15 min 42 sec)

The attached picture is the latest batch of stuff Horizon product support mailed me. Two 30A ESCs, three 40A ESCs, three AR636A receivers and an AR9350 rx plus a remote satellite receiver that had a saltwater encounter. This was in response to my mailing them the same items I had broken myself, not defects, mostly from saltwater, and with the AR9350 because I reversed the polarity when plugging in the voltage sensor leads (and I noted on the form that this was all my fault, but maybe you could replace the antennas I managed to sever, etc).

That's $540 worth of stuff (well, retail) in this last package.

They've done this sort of thing numerous times to the point that I'm feeling guilty when sending something in knowing they'll most likely give me a freebie, or repair an out-of-warranty classifieds-purchased DX9 for cheap or for zero dollars, or in just one case decline to fix a motor that had glue on it but offer me a good discount for a new one. Other freebies, again all my fault, were two or three other AR9350s (all stemming from the same first purchase, I kept screwing up the replacements), numerous telemetry sensors -- I can't even keep track!

On the $0.00 invoices they write "in the spirit of customer service." Yes, though it's also good for business, securing such a reputation and customer loyalty. And it's not just free replacements: When I send in a transmitter for something like a busted switch, not only will they fix the superficial problems, they will always do a thorough radio integrity check, flash the latest firmware, above-and-beyond work for which they won't charge me. The fellas in the Tundra thread have convinced me to try Frsky, and not just because the prices are comparatively amazing. But this is a tier of customer support I have only found in Horizon and HeadsUpRC. And the tier brings a tear to my eye.

Thanks, Horizon. And my man Jesse at headsuphobby, an outfit that deserves its own, separate post.
