I'll be heading off to DroneNationals on Tuesday to volunteer for the event and try to sell some PeasantCopters (PeasantCopter is an official DroneNationals event sponsor!)

I hope to see some of you guys there!

It's been a few months in the making, with lots of designs, crashes, and redesigns, but the final product is here! The first batch of PeasantCopter plywood miniquad frames are now in stock at PeasantCopter.com

I'll also be over at DroneNationals from July 14-17th to show off the frame and maybe even sell a few of them. Hope to see you guys there!

You can learn more about PeasantCopter here.

If any of you guys are interested in an affordable, repairable, customizable plywood 270-size miniquad, the PeasantCopter is now available for pre-order! I'm gearing up to submit a production order to the frame manufacturer (frames and hardware are 100% sourced from / made in the USA), so the first production units should be shipping to buyers in early July.

PeasantCopter's plywood construction allows it to be easily cut, glued, drilled, etc to your liking. I've had some nasty crashes into concrete and been back in the air with a few dabs of CA glue and some accelerator, which is something that's near-impossible with a carbon or fiberglass frame. Not to mention, plywood is cheap! PeasantCopter isn't meant to be the deluxe race quad, but it's easier to have fun on a $38 frame with cheap replacement parts and easy repairability with wood glue, epoxy, or CA. PeasantCopter's plywood construction also makes it lighter than a fiberglass / mixed carbon-fiberglass miniquad of comparable size; its all-up-weight is 164 grams.

The frame is capable of housing a GoPro (completely enclosed in front camera cage) and / or a Mobius Actioncam (mounted on top of front camera cage), and has space for FPV equipment and all the other bells and whistles. By mounting the flight controller under the battery, the PeasantCopter allows more space for both the battery and the electronics than a conventional miniquad, all while keeping the flight controller centered on the frame. This allows a...Continue Reading

I thought I would give a quick introduction to a project I've been working on for the past month or so: PeasantCopter! PeasantCopter is a cheap 270-size plywood miniquad designed to be affordable, durable, and customizable. A few of its design features include improved battery placement to provide proper center-of-gravity when using larger batteries (tail-heaviness tends to be an issue in other miniquads when using large batteries), the use of standard 4-40 fasteners available in any neighborhood hardware store, and plywood construction, which makes the airframe lightweight, durable, and easy to cut, glue, or customize in any way one sees fit.

The frame also sports a fully-enclosed camera cage capable of mounting a GoPro, as well as space for mounting a Mobius ActionCam. Right now the frame is in the pre-production process and will be undergoing flight testing for the next few weeks, but plans have been made to turn it into a kit ($35-40 price range) if there is sufficient interest. What do you guys think?

I got tired of keeping my transmitter in an old tool bag, and with the addition of my new FrSky Taranis I figured a case would be a worthwhile investment. After looking around for a new aluminum FrSky case ($70 shipped ), I realized it would be much more cost effective, and more functional, to make one myself. Many of the cases from Harbor Freight and other vendors look tough, but they're actually made of faux metal panelling. Most of the cases with the "rough" dimpling on the outside are actually just a thin sheet of metal foil on top of corrugated cardboard, so it took some searching to find a truly tough case.

I ended up buying a 18" Black Tactical Weatherproof Equipment Case from MCM Electronics for $19.99 with $8 shipping (I think I got lucky and hit a sale...it looks like the price of the case is now back to $32.99, which is still a great bargain). This case is seriously tough...waterproof, well-made, and it has a great solid feel to it. I think it could take a serious beating, just like the (WAY) more expensive Pelican cases it's modeled after. The 18" version I got can easily fit two transmitters and a few accessories, but MCM also has some smaller / bigger / wider / thinner cases of the same type--I highly recommend all of them! They also look like they'd be great for carrying quadcopters and other small aircraft for travel purposes.

The inside of the case had pick-and-place foam, and after about 15 minutes of laying things out and removing foam chunks, the case was complete. I'm pretty happy with how it turned out! I've got two transmitters in it, along with a leatherman and my FPV gear.

I hope this post might be helpful to anyone planning to build one of these or something similar! Let me know what you guys think If you've got any questions, I'd be happy to answer them.

It seems to be the perennial debate for multirotor enthusiasts...are they "drones" or are they "Unmanned Aerial Systems"? For my AP Statistics final project, I've decided to take a look at this issue. I've sent out surveys to a few hundred students at my school asking them to rate their opinions about unmanned aircraft. Each student is randomly assigned a survey using a javascript webpage I made. One survey strictly uses the word "drones" in reference to unmanned aircraft, while the other strictly uses the words "Unmanned Aerial Systems" in reference to unmanned aircraft. After all is said and done, I'll be running some significance tests on the data to see if there really is any statistically significant difference in people's perceptions towards aircraft systems based on what we call them. If you're interested in how things are shaping up, tag along and I'll keep you posted! The current survey data is available to view here:

https://www.surveymonkey.com/results/SM-DQBTMVX9/
https://www.surveymonkey.com/results/SM-55LFXVX9/

If anyone is interested in the results of this study, or has suggestions / future improvements for it, let me know! If there is enough interest I may try this at a larger scale over the summer with sampling from a larger population than the student body of my school

After months of putting up with the intermittent outages from my free hosting provider, I finally got the gumption to pick up everything and move it over to Amazon Web Services. It took a few days, but now all of my website's email, web server, and PHP hosting is done through AWS and the DNS has been reconfigured accordingly. Learning to run servers and set permissions through SSH took a long time, and even the FTP was different (I'm now using SFTP to connect to an AWS EC2 instance using a key pair, whereas before I was using unencrypted FTP to connect in a more simple fashion to my host's web server). That said, I've definitely learned a lot, thanks in no small part to the kind folks over at stackexchange and some linux and aws tutorials I found through google! It wasn't nearly as simple as the plug-and-play web servers I was used to from before, and having so much control over my servers is quite daunting...but, hopefully it'll be worth it!

The good news is, the website is now rock-solid stable, and it seems that all the permissions kinks have been worked out. This is my first time using amazon web services, so let me know what you think!

I did some more work on the JKM RC Solutions website! The website was down for the last day and a half due to a broken PHP interpreter, but everything's fixed now (well, mostly fixed...the web host I'm using is still pretty crappy, so the webserver occasionally closes the connection without sending data...I'm planning to move the website to a better host soon). I've added a page for custom wiring builds and will be adding more products soon. Stay tuned!

I've also started a facebook page. It currently has one like (me...lol). I'd love it if you could give it a like

Lol...I just bought $60 of servos and stuff from HK and I won a tablet. I guess their Paypal drawing is real, after all!

A one-picture summary of why it sucks to be an Amazon seller, especially for low-cost products.

Got DNS working on the website I'm building, so now the domain name is a nice .com instead of a sketchy subdomain: jkmrcsolutions.com

Still have to work on uploading products, but it's definitely an improvement! This is my first "real" website that I've coded from scratch, so I'm definitely learning a lot! I'd love to hear what you guys think about the website

I'm still pretty jazzed that my total hosting and DNS costs are <$2 a month. Pretty good deal! I used grendel hosting for website hosting ($0.70/mo) and GoDaddy for the domain ($12.99/yr).

I've had a few years of programming experience in school, and thought I would try my hand at HTML and CSS! I'm building a website from scratch for my (tiny) eBay / amazon / RCGroups online business (mostly building small battery connectors and selling battery checkers, etc). I'd love to know what you guys think! This website isn't nearly complete, but I've got the general layout down and I've done some work on the "About" page

Edit: I've also got an FB page for it! https://www.facebook.com/jkmrcsolutions

I've started selling RC connectors on eBay! I got annoyed with being unable to check / balance my ultra micro batteries using standard charging equipment and voltage checkers, so I did a few hours of research, ordered connectors in bulk, and started soldering! I figured that I definitely wasn't the only person to have this problem, and so far I've been right. I'm really making less than minimum wage in dollars per hour spent, but I'm doing this mostly for fun and to help out fellow fliers. So far I've learned volumes about soldering tiny things and working within the limitations of the USPS (their machines are great at eating things)--but I think I've got the kinks in the production and shipping process ironed out by now. If you want a connector, PM me or check out my listings on eBay!
