When I moved to SC I took down my server that was hosting a gallery of photos from the Thomas Edison field in NJ. A lot has changed in technology these past few years allowing me to put all those photos in the cloud. Hopefully this will bring back some good memories for anyone who ever flew there.

I had a great maiden with my Grafas MAXi 3.5 M this week. It flew great. I'm really happy it flies so well because it was not a great build. Top Model is getting sloppy and using a bad elevator design for years now that has proven to be a failure. They also undersized the wing joiners which was a challenge to get to the right size. When you spend this kind of money on an ARF I expect better quality control.

I finally got my DragonFly strong up in the air this past week. I ordered the kit from SoaringUSA almost a year ago. Overall the Valenta models ARF was superior to any Top Model ARF I have built. I powered this 3.5 meter sailplane with a Turnigy GliderDrive 3858 4.6 and YEP 80 ESC. The battery was a 4s 3000 Zippy. It does about 900 watts.

The DragonFly weighs 4.48 lbs and with battery weighs 5.26 lbs. The climb rate is almost vertical with this power setup. I have used GliderDrives in some of my other sailplanes and these motors are fantastic. For ~$35 I highly recommend these motors.

The radio setup is Hitec 225MG's for the elevator and rudder and Hitec 85MG's for flaps and ailerons. I used a Graupner MZ-24 with a vario sensor and a voltage dongle to monitor the battery.

The flaps on this model are huge. When you drop them 90 degrees the sailplane comes down dead slow and can be landed in a very small area. I recommend adding more throw on the elevator than what the documentation called for.

I hope the USA vendors start importing more Valenta models. I am very interested in seeing more of their sailplanes in my hanger :-)

I received my Graupner MZ-24 radio. I am going to retire my Aurora 9 eventually. My main reason for switching was Hitec's lack of support for vario sensors and overall the A9 has been abandoned by them. It was a good radio for it's day.

My first day impressions are mixed. The build quality is excellent. I saw some older videos knocking the quality and switches, either the radio builds were improved or someone just dislikes Graupner.

I am tad disappointed with the voltage telemetry. Coming from the Aurora 9 it's sweet spot was monitoring the voltage of your Lipo. It was easy and was built into their receivers via the SPC port. The MZ-24 has a telemetry port but no voltage sensor for some receivers. And their voltage sensor only supports up to a 4s lipo! They have a homemade solution using a voltage divider circuit for their GR-12 RX's (the L versions do not support this). Why they don't make this sensor is beyond me. It requires ordering two resistors, a capacitor and a servo extension cable. It works but it's too Heathkit like for my tastes these days. Many modelers don't even have the electronics skill to make it. Graupner screwed up on this area big time. Graupner wants you to use their ESC's which support voltage and a lot more features but at a hefty price tag. I use YEP ESC's from Hobby King mostly because they work great and more importantly they don't ding your wallet.

The gimbals are silky smooth. The two sliders that are normally on the side of the radio have been moved to the rear embedded in the grips. I think this is going to let me try and use them. In the past all the sliders on the side were too easy to move, having them in the rear makes sense. Most of the switches are 3 position. And the radio by default comes with a 1s 4000 lipo.

Past that I don't have enough time on the radio to judge it's overall features.

I moved last year and the club I now belong to had very few sailplane owners. Once I started flying my sailplanes at the field, the interest in sailplanes skyrocketed fairly quickly. Before long the peanut gallery started making comments about too many sailplanes. Next thing you know they coined it the "Sailplane Mafia". I decided to make a logo. The sailplane is my Elegant 700 and I used a Godfather font I found online.

I got a better video of the Elegant. This is by far my favorite looking sailplane. I love the colors. It's very easy to see.

The maiden went well with no issues. I used the suggested balance point on the wing joiner. It flew really nice. I had a rookie camera crew and could not get a good video. Get ready for a roller coaster shaky video

I have been wanting one of these for years. I found one recently on eBay and bought it. I used a KDA 36-10XL motor from Hobby King with a 12x8 folding prop from AeroCam. The ESC is a Yep 60 with a 3s 3000 lipo. I used Hitec 125MG's for flaps, Hitec 65MG's for ailerons and Hitec 85's for rudder and elevator. The radio is an Aurora 9.

During the build I decided to use carbon rods to support the music wire for the rudder and elevator. That made it much easier than running supports down the narrow boom. I also had to replace the included horns for the flaps, they were too small (height) causing a lot of slop.

I am 100% done with Castle Creations smoking controllers. I had an ICE 75 wipe out my heli last year and just had a TBird 18 go up in my foamy. Why is it that my cheapo Turnigy and YEP ESC's last and last. And every freak'n Castle controller I ever owned is in a landfill somewhere. I can't count how many Phoenix controllers died on me over the years. I am so worried about their crap products I am grounding the rest of my planes that still have one until I can replace them with some reliable stuff.

To celebrate the 4th this year I decided to try and tow an American flag with a UZI XXL which Hobby Lobby used to sell a few years ago. It was a bit tricky to get the flag to hang vertically.

I used a carbon rod in the leading edge of the flag and initially attached 4 earth magnets to the bottom of the flag (both bottom ends). The flag flew horizontally which is not what I wanted. I doubled up on the magnets and it was no better. I finally stuck two pieces of those lead (14 g) to bottom leading edge and it finally hung correctly. I mounted the tow hook on the CG of the lower wing.

I found a $5 amp meter on Hobby King's site that I used to measure how many amps my quad charger is pulling. Here is the video:

I got my Omega 2.5 meter in the air this month. This was an old ARF that my local hobby shop had acquired from an estate sale. For $150 bucks I jumped on it.

The build went easy enough except for the hinging on the ailerons and flaps. The hinge was part of the sheeting and it was very stiff. I had to score the hinge line with a knife to loosen it up. I really liked that the pushrod guides were pre-installed. Routing the servo wires was difficult in the wing, the guide the provided was a tad small to get two sets of wires in there.

I used a YEP 60 ESC, KD 36-10XL HK motor, 12x8 prop and Hitec 85 for the vtail and Hitec 125MG's for the ailerons and flaps. I used a 3000 3S pack and it balanced perfectly.

This is my newest addition. I built this sailplane during the winter months and started flying it in April 2013. It flies great. I used a KD 36-10XL motor from Hobby King, a YEP 60 amp ESC with 6 amp BEC, Graupner 12x6 prop, Hitec 65MG servos in the wing and Hitec 85's for rudder and elevator. The radio is a Hitec Aurora 9.

The build went well but Top Model made a couple of glaring design errors. The elevator is driven by a large bell crank that is supported by two balsa bushings that are pre-installed for you. The balsa wears out very quickly (in my case 7 flights) and then the elevator flops around with several inches of movement! It's easy enough to fix if you know of the problem before assembly. I did not and was not going to rip out the rudder to fix it. I used some thin G10 material on the outside of the fuse to support the carbon rod which goes through the bell crank.

Another issue are the flaps. The wing is only held down with two screws which means it does move slightly. If it does move during flight the flaps are so close to the fuselage they will jam. When I hinged my flaps I went as far out as possible which created about a 1/8" gap between the fuse.

The model CG's easily with a Turnigy 3000 3S pack. The reason I used the KD motor is it's heavier than a Turnigy equivalent. I hate using lead weight to balance. You will want to make sure you have a setting for 90 degree flaps. This sailplane is a real floater and I have used the flaps...Continue Reading

A few years ago going to the Thomas Edison field in NJ was all about watching what Bob Marz and Mr C were going to do. These two guys were so much fun you did not even have to fly your own model, they were going to provide all the entertainment. I wanted to share a video I took back then that I recently found on my computer.

I recently moved from NJ to SC. I had lived in NJ for 49 years. A day before the move I decided to stop by to say goodbye to an old friend, Horace Hagen. I met Horace back in 1976, the year I bought my first RC helicopter.

Horace was the guru of guru's back then. He had a couple of Kavan Jet Rangers when I met him. Horace spent countless hours with me trying to get my Dubro Tristar off the ground. It had a Heathkit Pack 17 radio in it that was not doing well. Horace figured out all the issues and more importantly taught me what to do and look for. We finally got the Tristar to fly and I was hooked on the hobby since then. I had lost touch with Horace over the years and just wanted to touch base before my move.

Horace worked for Bell Labs in Holmdel, NJ. I enclosed a couple of photos from back then.

Two in one week is very hard. Another friend, Bob Marz passed this past weekend. Bob was full of energy, he was the field comedian, he had more energy than most small kids. He added so much life to the flying field. He just recently retired and was enjoying the RC world more than ever. Bob we are going to miss you more than anyone....Continue Reading

This is a tough one, a good friend at the flying field past away last week. He had a difficult life fighting diabetes where both of legs were amputated in the last two years and was on dialysis because of kidney failure. He was a great guy, well loved by everyone at the Edison field. His favorite plane was the Contender, anytime he had that plane he was one happy camper.

Mr C was his nickname, very few knew his real name was Charlie Cunningham, everyone knew him as Mr C. Here are some photos of Mr C and his friends....Continue Reading

I found a nice 6 banana output channel strip at Tower Hobbies to cleanup my charging mess in my car. I always had alligator clips daisy chained in a mess that would easily disconnect while charging my lithium batteries. This strip is made by Integy and costs about $22. Itís a bargain for what you get. Itís fused protected and 4 of the 6 outlets are switched and have individual power LEDís. There is also a master power LED for the entire strip. It also includes 3 sets of banana plugs to retrofit some of your chargers.

I decided to remove the feet off the back and use Velcro to mount it to my marine battery. The cable going to battery is about 4í which is great if you prefer to keep your chargers out of the car while charging.
