Red20RC is one year old today!
Happy birthday to me 🙂
I posted the first post on this site exactly one year ago today. Since then I’ve got through several dozen sheets of foam board, a couple of ARTF models and more multirotors than I care to count. I don’t even want to count the number of orders that have gone through the HobbyKing website (and I really don’t think my wife or my accountant should either).
In the past year over 30,000 people have visited the site, reading 102,000 pages in the process. My 25 Flite Test articles have been read over 117,000 times and 41 YouTube videos viewed nearly 54,000 times. The Instagram account has well over 400 followers, Twitter and Facebook are somewhere around 300.
Overall I’m pretty happy with the way things are going!
Of course, Red20RC would be nothing without the support it receives from the community and I want to say a huge THANK YOU to everyone for sticking with me!
So, here’s to the next year. If you like what you see tell your friends, if you don’t then tell me!
This time I went for a folded wing in the hope that it would be lighter and offer better performance than the original.
The build was a lot easier than the KFm6 model. I only used 1 sheet of foam board with room to spare, which was an improvement. Placing the gear was also easier with all that space inside and no need to cut channels and slots in the plates. In fact, so confident was I that I even built one of my GoPro FPV bays into the nose.
It looked great, like a mini Zephyr. I got a 2200mah 3S in there as well and a 1100kv NTM 2826 at the back.
Well, it flew. In fact it flew pretty well. So why not an article and some awesome proximity FPV footage? Because it just didn’t fly well enough!
The weight was still up in the 700g range and it was just a bit too twitchy and unstable to fly FPV comfortably with it. Also, it wasn’t as robust as I’d hoped and just one fairly quick arrival removed the GoPro bay and damaged the center section.
I think the design is there but I need to get it more efficient and lighter. The ultimate will be a hot-wire cut wing…
R630 “Talon Pro” Upgrades
This is another one of those projects that has been going for ages and I have never got around to writing an article. Between problems with another frame and an unsatisfied feeling with the way the R630 was flying I decided to upgrade the motors, props and ESCs to see if I could improve things.
I wanted to use lower KV motors and larger props. I went for the AX2810Q-750KV 35mm motor matched with the 1255 carbon props. In order to save some space and improve the power distribution I decided to give the QBrain 4 in 1 ESC a go.
The upgrades were easy and the QBrain was an excellent choice, fitting nicely in the frame and the long motor leads meaning I could hook everything up without any soldering.
With a little spare time I took it out behind the house for some tests. The slower spinning props simply hum in the air and the frame is rock solid running a CC3D controller. After 10 minutes of cruising up and down the reserve I got board and decided to take the R630 for a walk. So, walking behind the airborne frame I went up the reserve, through the trees and back again. After a total of 20 minutes in the air I eventually noticed the red lights flicking on the LiPo alarm and landed.
This is now an awesome frame and I look forward to some longer range FPV flights when time allows (and maybe some decent footage and and article).
About 8 years ago now I designed a small balsa model for electric flight called the “Crash-e”. It was a great little model, an excellent first “bank and yank” type plane with great performance on the cheapest available gear. Shortly after, the plans were purchased by Traplet publications in the UK and I wrote an article that was published in the October 2008 edition of “RC Model World”.
I’ve decided to bring the model up-to-date and have this week started work on a 125% foam board version.
If all goes well there will be an article and this will be a free plan download.
Watch this space…
Changes in the Red20RC Store…
The Red20RC Store has been a slow burner. I’ve sold some frames and I’ve talked to some nice people about their projects. I added a lot of smaller products to the store but then I had a change of mind.
To put it simply, there are a million frames out there. You can get online and buy a cheap carbon glass frame or RTF quad and get flying that way. I can’t and don’t want to compete with that. I do Red20RC for fun and I just love cutting different multirotor frames, analyzing new designs and working out the pros and cons of each.
So, I’ve made some changes to the store and it boils down to three different services:
- You can buy a frame from my expanding portfolio of designs.
- I can custom build you a multirotor, either using an existing frame or working with you to create a completely new design.
- You can sell your own design through the Red20RC store. Get your frame cut cheaply and earn royalties on sales.
I’ll also be offering the occasional ARTF mutirotor package as well. More often than not these will be frames that are built up for testing or to be used in the creation of construction guides.
That’s your lot!
It’s time to get this article wrapped up. I’ve got plans to print and foam board to fold.
Thanks again for the support and do take a look at the store to see if you would like to get involved.
