PowerPanel for displaying GPS, and one switch to power up and start recording on the FPV-Japan DVR - which is powered by the onboard 8000mah 3S Lipo! All housed in a custom built CF and ABS box.

Also included are pictures of my original Ground Station, which used all the same components except the tracker, and some of radios....Continue Reading

Well, as the title says...Its been a while. Packed up and moved across the country, got a job and have kind of just relaxed into having fun on the weekends. I still have not flown anything and I need to find a place to fly that I wont get kicked out of. That seems to be the hardest part where I am at, finding a place where you can buz around without someone calling the police. But I am an outside kinda guy so got back into fishing and bought a fishing kayak. So for now they keep me busy and I get to enjoy time outside. I need to unpack my gear and find something to fly and crash.

I got more Team Associated SC10s than I know what to do with. This SC10 roller, that I got off of eBay, was supposed to be a parts donar. It's been sitting in man cave for the past year-and-a-half as decor with other shelf queens. It's time to break out some old electronics, and get 'er running. This time around though, the SC10 will be transformed, hopefully, into an on-road beast.

Got new servo to try out awhile back. Went to install...servo is 2mm too tall! Within that generalization of "standard sized servos", there is indeed great variances in a servo cases. Who would've thought.

Dr. Emel making it happen...
I'm sick of seeing the $12.99 JX servo not getting a chance to shine. Apparently the top of case is thicker than I anticipated. I can't wait to see how long it's going to last.

There's a bug in the trim steps and trim limits in OpenTX that has apparently been around for a long time, and which I reported on Github back in February of 2017.

Briefly, trims have a maximum integer value of 250 instead of 256.

256 is 2^8 or two raised to the eighth power, and would be exactly 1/4 of the maximum integer value of 1024, which is 2^10 or two raised to the tenth power. But 250, which is 2 x 5^3 or two times five raised to the third power, is 24.4140625% of 1024. In the midst of a system neatly based upon powers of two, there's an awkward and illogical value that's the cause of a big mess!

This appears to have been the result of a programmer confusing the percentage value of 25% with the integer value of 250, and in OpenTX version 2.1, one of its consequences is an odd behavior that I described to the developers in an attempt to prove my case:
Here's an oddity that fixing this bug will cure: In any trim step setting beside "Extra Fine" (2 steps per click), the values accessible when you start from zero are interleaved with the values accessible when coming back from maximum or minimum. For example, if your trim setting is "Fine" (4 steps per click) then if you start from zero you can select settings that are multiples of 4, such 4, 8, 12, 16, etc.

But if you go all the way to the current unintended limit of 250 and come back, you can only get to settings that are equal to 250 minus a multiple of four,

Being tired of my Sport Cub S2 Landing Gear bending after virtually every flight, I saw supports that were soldered onto the LG. I’ve noticed that the Carbon Cub S+ have identical LG and brackets. The version of the support struts that I saw at my flying field attached using the plastic holders in the rear for floats. Since I had floats, all the hardware, and solder, this project took about three hours.

Usually these planes are red and white but I covered mine in Econokote. My scale model example was Nate Saint’s Piper PA-14 flown into Ecuador’s jungles. He and four others were martyred. Their story is in the 2005 movie, “End of the Spear.” I also used fabric-coated rubber bands and rubber tubing for struts.

After having so much fun with my brushless-upgraded Blade Nano CPS, I decided to pick up a Blade mCPS. It seemed that the mCPS is a bit better supported by Horizon Hobby, or at least most of the parts listed on their site aren't discontinued like with the Nano CPS. Being just a bit bigger than the Blade Nano CPS, the mCPS seems better built and more refined than the Blade Nano CPS. Upon flying the mCPS, however, I soon discovered the stock brushed motor in the mCPS is pathetically weak, maybe even weaker than the Nano CPS! I could actually hear the brushed motor losing power throughout each pack I flew, and the mCPS had nearly zero climb-out towards the end of the pack. There have been many discussions in the forums about potential causes of the mCPS's anemic power output, but I immediately knew that the mCPS desperately needs a brushless motor upgrade!

Unlike in the case of the Nano CPS, Horizon Hobby still offers a plug-n-play brushless upgrade for the mCPS. There is a wide variety of different approaches to installing a brushless motor into the mCPS, and many pilots have posted builds using various powerful brushless motors and ESCs. The easiest way, however, is to just go with Horizon Hobby's brushless motor, BLH5104, and brushless ESC, BLH5105, as shown in Fig. 2. Unfortunately, this brushless motor and ESC add about $50 plus shipping to the cost of the mCPS, pushing the total for the BNF version close to $190! Since I really wanted this compact helicopter...Continue Reading

After two years we’re back out in the NorthWest. Today is a blur. Most of us had gone to bed at midnight, gotten up at 4:30AM and then spent almost all day flying across the country. By the time we had rounded up our rental cars and reached Hood River it was 5PM and we only had a couple hours of light left. We elected to head to The Dalles slope. It was close and easily accessible by car. The wind was whipping at 30mph and Tom swore he felt a gust twice that amount as we reached the site. DJ pulled out his combat wing. Amadeo his Electron. Tom and Ben had their Gulps. Jose and I elected to take pics. The air was a little to strong and turbulent for unleaded foamies. After an hour, with fading sunlight, we packed up and headed down to Clock Tower Ales for some IPA’s and good grub.
As I write this, Tom and I discussed the best slope(s) for tomorrow. With a 20mph wnw wind we think we’ll hit Lumber.

Just having another fun build stretching a 250mm (approx. 9") frame using T6 Aluminum to 12 inches platform. Only the CF frame was replaced and all the VQ250 components are being used.

Not much to say and I can't complain the way it's flying and with 3 switch mode on my TARANIS PLUS , it can fly straight horizontally on fast forward flight for racing and can switch back to a normal quad if needed.

Spirit 600 flying wing from Fasttech $20 USD shipped - https://www.fasttech.com/p/7327502
Hot SKY3025 2.5g Micro Servo off Ebay $4.19 each
4ch Frsky Rx from Banggood - https://www.banggood.com/2_4G-4CH-Mi...r_warehouse=CN
6 amp ESC off Ebay
Motor from GB - https://www.gearbest.com/motor/pp_11...ml?wid=1433363

The goal - to build a 100 gram RTF flying wing ( Or better )
Yes - just completed it ..

Pic 1
Pic 2 The completed Wing

Both ESC and Rx were fitted to the side of the fuse with double sided foam tape + a zip tie
Servos were hot glued into the wing
Pic 3 / Pic 4
The wing tips and control hardware did add weight where it was not wanted , behind CG ..
I still have not installed the propeller , and the 250 mAh 2s battery just , and I mean just balances at CG ..
Weight without the prop and with the battery was ....
Damned close to 90 grams = 90.5 grams ( less Prop )
So I dare say I made it past 100 grams with room to spare .

I may have to buy some slightly larger 2s batteries , maybe 350 mAh ...
Wonder what I have in the battery box ?

Picture 1 :
Put some lines on the wing ( CG ) as well for servo placement .

Picture 2 :
I cut the tabs off the servos , made some holes in the wing and set up the servos

Picture 3 :
Before I glue the servos in , it would be nice to know they work , well that everything works .

Picture 4 :
Wing has been Epoxy glued to the fuse , servos hot glued into the wing , servo leads buried into the wing along the CG

All that's needed now is to put in the Rx , connect elevons to the servos , glue on the tips , and hope that everything balances far enough forward to use a nice small 2s battery . ( Oh and the self imposed weight limit of 100 Grams RTF )
