Last weekend, Evelyn and I spent three days at Free Flight gathering in Lost Hills, CA and it was AMAZING!!!
For many of us in this hobby, we started flying rubberband powered models, then progressed to control line and finally RC. The world of free flight model aviation is a lot bigger than I ever imagined and very exciting. Evelyn and I have made it our personal mission to do what we can to help spread the word about free flight since we truly owe the pioneers and those who continue to keep free flight modeling so much, for their contributions to model aviation.
Here's a letter I wrote to our new friends in the free flight community:
First, I would like to say what a thrill it was for my daughter Evelyn and I to spend time with all of you. Thank you for making us feel welcome and a part of the free flight community. Each of you represent the very best of model aviation and inspire us to share your passion for free flight with those who've never experienced or understand the various sides of the hobby. I'm hoping through the power of photography, videos, and personal experiences to bring more attention to your amazing world of free flight. The statement that was repeated by many of you was, "Our hobby is slowly dying!" Needless to say, I think we all would like that to change or at least be prolonged through our efforts to keep promoting and reaching out to those who may not have been exposed to this part of model aviation.
Finally got a 450. It looks smaller than I imagined it to be hehe blades balanced perfectly !? Cog needs to be checked. I assembled some parts to have a look at it. Tail is the next job. I dont like the Jesus bolt nut. Tho..
It was Johnny Cash who once sang Folsom Prison Blues although it can be said he never thought of drone pilots in mind when writing this tune. More recently, with Canada and more lately China, drone pilots can have strict fines or penalties. Such is the case of Tony Lin, a college student in China who spent time behind bars for flying in an area considered a no fly zone.
So I took another big step forward today and ordered my motors and ESCs.
I ordered (six) "SunnySky V3508-29 KV380" motors from BuddyRC
and (one) "Kensun Power Distribution Board with 5V 12V Output"
I opted for the free shipping because well, I'm still months away from first flight.
That came to about $166.. I almost went for the SunnySky V3508-20 KV580s but in the end I decided to get the slower motors, I'm not looking for speed, I want to lift cameras and get max flight time.
I really don't know WTH I'm doing yet but I read a LOT and watch tons of youtube videos.
The other thing I ordered today was my ESCs. I ordered (three) of the "XRotor PRO 40A ESC (Dual Pack)" which of course gives me six ESCs.
I chose the standard long wire version. I plan to mount them on the main body.
That cost me about $146.
And that's all the money I can spend this month.
Next month I am going to order the props and some of the smaller electronics and probably the retractable landing gear.
I need to keep it below $300 a month.
A few weeks ago the Frsky M9 hall effect gimbals came in and I put them in my Taranis X9D Plus. That was pretty easy.
I calibrated them as far as I could using the built in calibration option. I suppose there is a better, more precise way to do it but I'll worry about that when the time comes. It came with an X8R.
I've decided that I'm going to stick to 100% open source stuff. That rules out DJI/NAZA...Continue Reading
As some of you know I have been very critical of having to wait to almost 2 years for a "Pre-Ordered" product. Soloshot claims that this was not a crowd sourcing venture. But last time I checked it doesnt take almost 2 years for a pre-order to be released.

Time to build my ARC Great Lakes biplane from modeltech. Picked this kit up a few months back as I love biplanes. In my usual manner and in the excitement of getting a fairly unique biplane I clicked the buy button before doing my research. I wasn't able to find much but when I did the reviews weren't very good. Most complained of poor handling... ugh! Further research brought me to a post where the fellow had good luck by adjusting the incidence of the main wings to fit more in line with a typical biplane.
This plane was built for IC so mods would have to be made for electric. Most importantly an access hatch for swapping batteries. I haven't decided on a power setup yet but pretty sure I'll go 4S. Initially I am thinking a nice heavy Cobra C-4120/14 710K motor weighing in at just under 300 grams. The plan is to get the plane assembled without covering then get a rough idea of how much weight I'll need in the nose to get it to balance at the aft point.
I started assembly a few days back and got the lower wing mounted last evening so time to do an initial incidence check of the wing. I got the rear h-stab temporarily mounted and checked to find that it is parallel to the thrust line. With it level I checked incidence on the wing and was at -1 degrees. Ugh! Shimmed it 3/16" at the trailing edge and was able to get it to 0. So now time to build up the wing bed. Ideally on most aerobatic bipes I's want +.5 but the plane will start to look goofy to get that. The wings are a symmetrical airfoil so this plane may be better tuned for a 0-0-0-0 configuration. I think I'll still put -.5 on the top wing when it comes time.

Keil compilation instructions for silverware:
Compiling a firmware with custom options is done using the software program Keil, on windows. This currently is the correct procedure for Bwhoop b03, E011 and also H8 mini with blue board. Use the right code for the board / quad please, they do not work correctly otherwise.
2) Install STM32F030 cpu support pack using the pack installer in Keil uVision. You may also skip this. Keil uVision will ask to install the pack when the project is open, if not installed. Choose "install", and wait for installation to complete (download). This will take some time.
Assuming the installation process was performed correctly, we will now use Keil to compile a "binary", which is the file containing the firmware of the quadcopter.
2) open project file "/Silverware/silverware.uvprojx" or similar in the Keil uVision program. This can be done by double-clicking on the file for example.
Keil uVision may ask to install device support if not present, click "install", and wait for completion, which may take some time as it is downloaded.
3) Change the settings to your preference, generally using config.h and pid.c for acro pids.
3) compile the project and make sure there are zero errors reported in the lower part of the window. Use either the "build" toolbar icon, menu "project/build target" or "F7" hotkey. Keil will also save changes to files at his point.
4) Open the folder "/Silverware/Objects" ( name may change slightly) and find file "bwhoop.hex". This is the firmware file, to be flashed to the quadcopter using the "st-link utility" program.
