Hobby King Orange 3-Axis Stabilization in the Eflite Cornell

I tried the Spektrum Alpha 6 system in the Eflite PT-19 Cornell. I turned on and let me set it up just fine, again would not see the Knob on the DX8, so put it on the Flight Mode switch. Got it set up just fine, but when I tried to turn it on again, time and again it just would not come on. So its not the Waco, or the DX8, its the unit.

I realized that I had an Orange 3-Axis Stabilization system, so I installed that. Took 15 min, including programming, gain setting, and it works just fine, including the remote Off via the Gear channel. If there was ever a plane that needed a stabilization system, this tiny light bird is one.

I realized that I had pirated the receiver for some other project, but had a Spektrum 6 channel (simple, old one I have had forever) laying around, so that's in there too.

I haven't flown her much. I have her because it was the second Cox 0.049 U control plane I owned as a kid. I am kinda excited to fly her off the Geotex at Misfits in Auburn. The picture below (from the interwebs) will bring back some memories! Thin plastic held together with rubber bands and flown with a wimpy simple handle. (The first plane was that Cox odd colored Sopwith Camel, and the third was the Stuka Dive Bomber).

Phoenix Waco 26cc Spring Start Up!

I have written about my issues with the Spektrum Alpha 6 Stabilization system, which I have finally removed from the Phoenix Waco. Today I took her out to the garage to run up the RCGF 26cc engine, and she ran perfect. Can't wait to get her in the air!

Sweet 30!

Got the DLE 30cc Breitling MSX-R out from under the winter dust to start her up. Fueled up, a couple of choked turns and she sputtered. Pulled out the choke and she started right up! Its so nice when things just work! She went full throttle just fine, idles sweet, and transitions the throttle smoothly and quickly. Made some adjustments to the wheels, gave her a bath. She's ready to go! I love this plane.

Spektrum Alpha 6 Sucks.

This is the Spektrum Alpha 6 Stabilization system, using their AS3X technology, installed in my 26cc Waco. I hate this thing. I hated the first one, that malfunctioned right out of the box. I hated it when it turned out only one guy at Spektrum knows this thing, the manual is useless, and you have to connect it to a computer to set the gains, which requires you buy a separate cable (they gave me one free as we were trying to fix the first bad one). They sent me a free replacement which worked with a bit of tweaking. I hated it when no one could tell me when I would want to fly Rate Mode or Heading Hold Mode (best I could find was that in Rate the response deflection is momentary, in Heading Hold it stays on until ??. I fly my helis in HH, but am not sure how this applies to a stabilization system). Spektrum said I would want to fly in Rate. Or was it HH? I hate this thing.

I hated it today when I turned on the receiver  for the first time since the fall and it all seemed to work just fine, thought he gains seemed kinda massive. Went to dinner, turned it on again and now it won't even turn on (the receiver is on), nor let control commands pass through. I saw a YouTube post from Spektrum about the 1.2 Update, and tried to install it, but it says its not for my device. I hate this thing. I tried just resetting it up without using the computer, and it won't turn on, though I see a momentary flash as I power up. I planned on trying to use the Aux Knob instead of the 3-position Flight Mode Switch, because the Horizon guy suggested that the gains could be set using the knob. He didn't recommend Rate versus HH. I hate this thing.

I hated it when I tried to connect it to the cable and the computer. The Spektrum software would indicate "Cable Connected, No Device", no matter how I turned on what. Then it would, but then it wasn't. 

I hate this thing.  I am going to spend a little time trying to get it to work again, then when it doesn't, I am removing it and throwing it into the woods as far as I can. I am recharging the batteries and will try again later.

I hate this thing. 

I really, really, hate this thing.

UPDATE (5/12/2017):  This morning after charging the batteries, I had the same result. I videoed my attempt to get the Alpha 6 to turn on, and it did once out of all the tries, about half way through the video. I also tried changing the switch to the Knob on my DX8, but when it did turn on, it wouldn't respond to the knob, only the 3 way.I have removed it from my Waco and will send it and the other brick, back to Spektrum to see if they can get it to work. I really think its just bad luck... I hope Horizon will make good on these.

Horizon Hobby replied to my review and shared the difference between Rate and Heading Hold. Rate will make adjustments for turbulence, Heading Hold will hold position. In HH, if I put the plane into a knife edge, the unit will keep it there. For most flying, as I think they told me once before, Rate Mode will be the choice. 

I may try to install it on another plane. If I recall, when I was trouble shooting this last year, changing the model on the DX8 fixed the problem.

ADDENDUM: Put it on the Cornell and it still didn't work...  Put an Orange one in and it works fine.

Eflite Cubby Wing Update

I did some more work on the Eflite Cubby wing today. I ordered the Cub Yellow cote from Horizon Hobby through Amazon, and it doesn't come Prime (2 day), but will take about a week. The whole point was to order it from Amazon for the Prime shipping instead of direct form Horizon as I usually do. Meh.

I sanded down the epoxy, and afterwards filled the slight imperfections with Hobby-Lite. Smooth as a baby's bottom. Sweetly straight.

I decided to drill out the old spar. It was about 1.5 cm on each side. This is the wing side.

This is the center piece side.

Melted a hole in my brand new Batman Hoodie with a hot drill bit. Awesome...

The new wing spar. Ridiculously small. Cut it from plywood and sanded to fit.

15 min epoxy, filled the slots where the spar goes and the joining sides. 

Came together nicely.

Nice and straight!

The plastic connectors that were originally on the damaged right wing snapped in the crash. I moved the remaining ones around so that there are 4 of the original white ones on both wing strut ends, and used control arm snap links from my HDX 500 heli repair kit to replace the damaged ones where the struts attache to the fuse. Perfect.

Waiting for the cote to come in, which will let the epoxy set well. Once the cote is in, install the wing and back to flying condition!

Bushed the Cub, Rocked the Sukhoi

The weather was perfect, really, so I was going to fly today. I loaded up the Sukhoi 10cc, which I haven't even started since last fall, and the Eflite Cub, then headed out to Joppa Fields, just in case they fixed it. Which of course they haven't. The grass has been cut, but its still tall to mask the clumpiness. I've really just had my fill of that. I got back in the car and drove out to Merrimack and the field for the Southern NH Flying Eagles.

Its a nice field with a geotex runway and very nice recently mowed grass, but I don't enjoy flying there, with having to fly in and out of the hole formed by the surrounding trees, which you pretty much have to fly over at least 100 feet in the air to avoid, and the wierd wind patterns that come off the river and spin into and out of the bowl and around the trees. I think I have not flown at a club with more crashes, which I attribute to the trees, the bowl and the winds.

And pretty much everytime I go there something crashes due to the heights, the winds or the trees. Today the Eflite Cub got wisked sideways then into a spin, in the corner over the creek at the northern end, after flying with busy fingers down into the bowl. She ended up in a bush just short of the creek. Motor is loose, right wing came off clean and has a break in the outer leading edge. Meh, easy fixes, already in progress.

The Cubby is a very nice 450 sized balsa framed plane. A nice predictable flier.

In the bush...

Right wing took the brunt, but came off clean. Well designed to break like this instead of being so strong the energy turns it into matches.

The leading edge. I used 15 min epoxy to allow me to work the pieces into place.

I placed a piece of balsa sheet cut to fit perfectly between the wing formers, and to fit behind the rejoined leading edge. I need to get some Cub Yellow cote. Thought I had some, but nope.

This is the trickier part. Do I want to drill out the joiner spar, which would be strong and easy to do, but will take some work, or drill a hole and run a carbon fiber rod between the two. This latter option  requires a little more finesse ensuring the rod is in the same place on both sides joined. This option is weaker. Meh, I think I will take the time to drill it out and make a new plywood spar joiner. That is a project for another day.

I love this plane. My RCGF 10cc powered SU-26, is a lot of fun to fly, especially with the Orange stabilization system. The system is switchable allowing nice clean aerobatics with it off, and with it on, nice handling in windy conditions. She started right up and needed NO adjustments! Ran sweet and reliably.

On the geotex runway after a flight. Flew a couple of tanks, 15 min each.

Then the plastic control rod end that was embeded in the rudder broke off. I could fly her castering, but with the cross winds this was a bit tricky so I called it a day. This took about 10 min to fix at home, and I decided to double up as these take a beating on grass. Fixed. I also took some time to straighten and align the aluminum landing gear that also took a beating out at Joppa Hill last fall, another reason not to fly there. Recall I have had a lot of landing gear ripped off there.

Sean showed up. Twice. Forgot his wing tube the first time. Flew his glow 0.55 equipped Phoenix Cub. Ran sweet, took off fine, and then I left him to the winds.

It was a good day. Not sure I will fly there again, but its a great club, some really great folks. I just have better options than flying in and out and over the hole.

Ignition or Hall Sensor?

Thanks to the gang at RCGF-USA, the new ignition arrived today, wicked fast shipping.  I installed it today, and at first, nada. Dammit. I tried a different Hall sensor and it flashed, curiously without the spark in (forgot to put it back in!). Didn't want the new ignition to short, and replaced the spark and it still worked. Realized there apparently are two different sides to the Hall sensor... tried the original one curved side down and it sparked. Hmm... I am not even sure the original CDI is bad, so I am keeping it. Anywho, the engine started up and ran fine. I retarded the sensor a bit and she runs even smoother. I haven't played much with the timing, so this was nice. Throttle advanced smoother too. Sweet. Ran her a bit, but too windy to fly. I did have to remove the 4 blade prop. It just didn't have the ruggedness required for the gas engine and was splipping on the prop shaft. She flies great with the Master Airscrew Scimitar.

I am loathe to return to flying at Joppa Hill with the clumpiness of the grass and how hard it is on my planes. I have lost so many landing gear there, and will never fly the Waco with her wheel pants there again. Pretty soon the road to Misfits in Auburn will dry out and I will fly pretty much exclusively there and on occasion at Hudson.

Looking for some flight time on Thursday!
