Just digesting the recent announcement by the FAA/DOT/AMA requiring all RC pilots to register.

I never would have thought it possible and to have come to this. Truly a sad day in America.

Some appropriate memes:

I managed to get some flights on the CG mini Super Chipmunk on Sunday. She flies beautifully, brought back memories of my larger, glow powered SC from many, many years ago.

Wx has been c r a p this week. Too windy. That's let me have some time in the shop to finish up a new project. I should have pics soon.

Also expecting a data logger arriving soon from Esprit. Plan is to fly it in the Albatros to see what sort of flights I'm getting.

That's all for now....

The Viking has been redeemed.

I had seriously considered putting the Viking up for sale. A little less than two weeks ago I had flown it again and the results were less than stellar. I thought I had the flight issues sorted but I went to the local schoolyard for some flights the same old crap started again...and worse. Very erratic flights and the icing on the cake was a takeoff that resulted in completely destroying the prop and scraping the wing tips and nose. Very ugly. I was not a happy camper. After a day to cool off I decided to repair the damage. The biggest issue was the replacement prop. Seems like Horizon (and therefore everyone else) is OOS until mid-November. Some searching around led me to discover I could use GWS 7x4 props. A quick order to Tower and they were on their way. The foam damage required some repair. I grafted in some pink foam to the lower wing tips and the cowl chin oil cooler scoop where the crazy take-off attempt ground them to powder. Once the glue was dry the grafted on foam was carved to shape. I used lite-weight filler to smooth things out and hide the seams. After everything was sanded I applied a bit of touch up paint.

Well, today's weather was perfect for a test flight. I had all I needed and headed out to the sod farm. I also re-read the owners manual. On page 13, in the troubleshooting guide, the second item in the troubleshooting guide states : Model flies inconsistently from flight to flight. Two items are listed as possible...Continue Reading

This past Saturday was our club's Labor Day float fly. I only brought the Beaver this time since I didn't feel like messing around with another plane. In hindsight perhaps I should have brought the Tidewater but, such is life. I did bring the UMX Pitts as well but more on that later.

Condition s were perfect for float flying. light wind, sunny skies. I arrived around 8:45 and got unpacked and set up. There was a good crowd already getting set up. I flew the Beaver for 3 flights and was hoping for a fourth when disaster struck.

Yep, the prop on my Beaver got me. I was getting ready to take the battery out after a flight and when reaching over the prop to access the battery hatch the TX stick got bumped and in my haste to try and prevent it from going further it did the opposite and my forearm got sliced pretty good.

Fortunately I had a paper towel stuffed in the drink holder of my chair and was able to apply direct pressure on the wound. Every one was scrambling to find a first aid kit and generally freaking out. I had more than a few comments on how calm I was. I had to direct them how to make a dressing for the wound.

A fellow club member and another Beaver owner, helped get my car packed and I was able to drive to the ER. That was the worst part. I sat there for almost 5 hours before they finally got me stitched up. 15 stitches.


I'm attaching pictures but be warned...they are graphic.........





As with any incident there isn't any singular cause...Continue Reading

Despite the forecast and wx radar showing rain the day actually improved and by noon it looked OK. So I headed out to the glider field with the Albatro and the ROC 2.2m V-Tail for some soaring action.






I had not flown the V-Tail since last year, which is a shame since it's a great flying plane. I managed to find lift throughout but it was a bit disorganized. But lift was there, even though there was a high overcast and 8-10mph wind out of the southwest. I think my longest duration before I had to motor back up to altitude was around 6 minutes. I was averaging 4 min of lift. Both the V-Tail and the Alby penetrated the wind nicely. I managed 2 20 min sessions on each plane using 1 battery pack per. Not a bad bay. Of course by the time I left the clouds had started clearing and the sun came out in full. I'll bet the lift got better. Ah, maybe next time.

I was able to get out to the school lot for a quick verification flight. The added washer under the top motor mount screw did the trick. Just enough down thrust now. I only made a 3 1/2 min flight but it was enough to validate what mods I made.

She flew much, much better. No 'tail heaviness' what so ever. Ailerons were more responsive too since adjusting ATV to 125%.

Hopefully this weekend I will be able to get out and fly her some more.

I'm much happier now with this plane.

Finally was able to get to the school yard to fly the Viking for its maiden.

T/O was fine, didn't need full power, however flying around the plane acted tail heavy, which is strange since it's balanced right where it's supposed to be (45mm back from the LE of the top wing). So I added down trim and it helped. I added more power and the nose went up again, worse this time. Back off the power and tried to do some circuits but the whole time it didn't feel right. Adding power exacerbated the apparent tail heaviness.

Ailerons were also sluggish, like there wasn't enough travel. I didn't try switching to 3D mode.

I decided to land. Power back and she glided fine. Although I ran out of elevator for the flair and it 3 pointed a bit harder than I would have liked.

Took her back to check things out. The battery is as far forward as I can get it. I'd like to try to lay it traverse (long axis of the battery parallel with the roll axis of the plane) but the motor wires really won't allow that. Besides it balances where it's supposed to with the long axis of the battery going with the longitudinal axis of the plane.

I adjusted the travel volume on the aileron servos to 125%, added full down trim on the elevator and gave it another shot. Same T/O as before, roll was much more sensitive but still didn't feel right. Same issue however with seemingly tail heavy, especially at higher power settings. I made two circuits and decided to land. Same approach as before, just shut the...Continue Reading

Last Wednesday the replacement motor from Horizon arrived. I got it swapped out no problem. Only issue was I had to change around two of the motor wires on the plug because as supplied and hooked up blue/blue, red/red, black/black on the wires the motor ran backwards. After that was sorted all I had to do was wait for a good day. Unfortunately weather wasn't cooperative until Sunday afternoon...and even then it was a bit windy. I scouted around the local area for a good place to fly. I didn't want to drive 30 min to the club field and I didn't want to use the soccer park since I wanted to do a wheels t/o and landing. The local middle school was an acceptable choice. The lot was empty and light poles and other obstructions were minimal and it was oriented with the prevailing wind. I loaded a battery, powered her up and took off. Minimal t/o roll required.

She flew fine in the wind, and it was gusting pretty good. At one point I was doing zero ground speed. The ASX3 handled it fine. There's no way you could fly a plane this small and light in the wind without it. Still, it was a challenge. No lazy slow flight today. After 4 min on the timer it was time to land. That was the tricky part. My first approach was almost like a Harrier. I was at half throttle and pretty much zero g/s It may look cool but if the wind should die, then your in a bad spot behind the power curve and with not enough altitude. i decided to do a go around and try again and keep some more speed up,...Continue Reading

After contacting Horizon Monday morning, getting transfered, put on hold, more waiting and finally electing for a call back, Horizon's customer service contacted me
I explained the problem and they determined from my description that it was the motor and proceeded to send me a new one. FedEx no less. Tracking shows it on the delivery truck right now. Nice.

As a side note, I found my old UM Sbach (which had a destroyed nose) and I swapped its 2500kv motor for the one in the Pitts. Plugged it in and it functioned perfectly. So it is the motor that's bad. I feel better that I won't be chasing the problem. But it leads me to wonder what caused the motor to go bad or if was just detective to begin with. I read one other report on the UM Pitts thread of someone who had the same issue as well as another video on YouTube of the same. So it does seem to be a QC issue. I'd be curious to see what E-Flite's sigma rating is. It certainly isn't six sigma (probably not even 1 sigma......of course I'd need to know the production run and how many potential defects there could be to make a meaningful determination)

This was definitely a busy weekend for RC activities. On Saturday the intent was to maiden the Albatros 2.4. Wx was perfect, light wind, highs in the low 90's, sunny skies. After my daughters soccer tournament game I stopped by the LHS to pick up a spur of the moment purchase decision...E-Flite's new DLG....the Whipit.



Back home I put the Whipit together, got it bound to my DX6i and checked the controls......which took probably a sum total of 15 mins. The I loaded up the car with the Albatros, UMX Radian and the Whipit, my field box and radios and headed out the the field. After getting my shade set up I set about putting the Albatros together. All was going well until I turned the battey and Tx on and the rudder servo started chattering really bad. Wiggling the sticks didn't help anything. Great...... So I remover the wing to get a look at the servo. Closer inspection gave indication of stripped gears. agai...just great. How the heck did that happen? I hadn't bumped the rudder or even flew yet. (I was using HS-85BB servos) So I took the servo out, disassembled it and sure enough, stripped gears. AAARRRGGGHHHHHHH! Good thing no one was around to hear me. There goes the plan to maiden the Albatros. I made a quick call to MTH to see if they had some metal geared HS-85's. They did and would hold them for me to get later in the afternoon. Oh well, no sense in wasting a good flying day and I had another plane to maiden. So I packed up the Albatros and got the Whipit out....Continue Reading

At my daughter's soccer practice I managed a maiden on the UMX Pitts, and flights on the Radian and Stearman.



The Pitts needed massive left aileron trim but it flew great. It is one sweet flying plane. Who would have thought a micro Pitts could be so well behaved. I love it!!!
It turns out the trim was off so much because I forgot to reset the sub trim setting from the previous plane that was in that memory slot. It's all fixed now so the next flight should be even better. Did I mention how much I love flying that Pitts?

Just got this one and managed flew it for the first time yesterday evening at my daughter's school. It's E-Flight's UMX PT-17. It really does live up to the praises it's been getting. A very nice flying micro. Despite a bit of wind the ASX3 gyro controlled receiver makes this plane very well behaved. Often times micros don't do well outdoors, especially 1S planes, but this one is awesome.



Stearmans have always haad a reputation for handling issues and flying qualities, which can often get magnified when you scale them down. This is my third (and smallest) Stearman and it performs just as well as its bigger brethren. Now if they would only offer it in the Navy N2S colors.......

I went out a few weeks ago with my T-28 Trojan. It was a bit blustery that day. My son took the video with my phone....

Eleven years ago I bought my Navaho. It survived two moves and all those years in the basement, patiently waiting for me to get around to it. Well I finally dusted off the box and built her.



Here are the build pics....


I had to make a jig for the fuselage to join the boom and pod.

Well, I am a float virgin no more. A few weeks ago I made my first flight off of floats. For Father's Day I got myself a Flyzone Beaver. This is truly a great ARF. It builds quick and it flies fantastic. They give you both conventional wheeled landing gear and floats in the box. I performed my initial flights with wheels at the club field. A week later was one of our annual float flys and I took the Beaver out to give her a try. It was pretty breezy that day but after seeing a fellow club member fly with his little Icon I decided to give it a try. It was no big deal. Take-off was perfect and the Beaver flew great, even in the wind. You could tell it was windy but the plane was big enough to handle it. She was just blown about a little bit. Landing was just as easy. A great flight.

Local club member Dave Evan took the pictures....
