I haven't posted too much about this plane and think I have had it over a year now. I got this one used from a fellow RCG member. It had been crashed and the nose of the fuselage repaired. Cosmetically it looked good but structurally it failed on the first flight. So after putting some bandaids on it for awhile it was time to actually get hands on and repair it. Most of the old repair had to be cleaned out and a new fuselage harness installed. The servo tray was reinforced along the edges with fiberglass up past the canopy lip. This allowed me to rebuild portions of the lip that were originally missing up toward the front. The inside got two layers of CF cloth extending past the break and tied to the ballast tube. I continued the CF up along the top rear of the servo tray as well to spread out the load. Once that was set up, the outside was ground down to reveal just how bad it was. Two layers of CF were added to the outside and then it got prepped and painted. Now it is back in action and will move along quite nicely in some good wind. This plane likes weight and small control surface movements allow it build some speed aka the "less is more" approach with this setup. In light wind it will fly fine but it is more fun in the 15-18 mph range at the slope I frequent. It is referred to as the Death Dealer at the slope and so I had some fun and ran with the theme. Callie set me up with a Grim Reaper graphic for the wing.

A fresh set of wings is coming of the workbench and getting ready for covering soon. This is a fully sheeted wing without the polyhedral and with the addition of ailerons and flaps. I will post photos in the old build log here - http://www.rcgroups.com/forums/showthread.php?t=1845148

I decided to do a build log on the Aquila. It can be found here - http://www.rcgroups.com/forums/showt...8#post24325509

Also put some footage together using a new keychain camera mounted to the wing and tail of one of the gliders. Just out having fun.

Rounded out 2012 with a little time on the slope with some formation flying and aerobatics at sunset. It has been a fun year meeting some new friends and also getting my father-in-law behind the sticks a few times on the hill recently.

Last year saw the addition of a couple of planes as well as a couple being sold. Most of my flying time now is on the slope and the electrics have a little more dust on them. I even broke out the building board and pieced together most of an Aquila kit that I have had since 1982. I plan on building a second set of wings for this plane and convert it to a full house ship. Maybe a build thread on this plane might be worthwhile. Also plans are in the works to take on a Merlyn build.

I hope everyone has a great New Year.

I had a chance to watch Endeavour making part of its tour of Los Angeles. Really neat stuff to see this in person and the timing of events just happened to work out. Not the best quality video but thought I would share it with those who might be interested.

Had some fun on the hill breaking in a F3J glider this weekend. It did really well up there and was faster than I thought it would be. The Shadow is a real nice, stable flying glider and it will slow to a crawl for landing.

Got back to the building board to try a different airfoil on this glider. It originally came with an E374 and was covered with Kromekote paper adhered directly to the foam core. It worked pretty well and since this was designed for combat (read quick rebuild) it served it's purpose. My original wing had seen better days with a previous break (25 years ago) and getting rain soaked. It still flew and I considered it a beater. I tried my hand at DSing it one day a couple of months ago and stuffed it into the ground breaking the wing again at the previous repair. An aluminum arrow shaft that I stuck in the wing on the first repair held it all together and kept the wing from folding. It will glue back together but I thought about going a different route as an experiment.

I started the new wing with some foam cores cut by Flying Foam (flyingfoam.com) to the RG-15 profile. It has a straight T.E. and tapered L.E. I wanted to also change the original design slightly by adding a servo for each aileron and increase their surface areas and deflections. The wing also got lengthened about 6 inches. Not sure if this was the right choice given the length of the fuselage but I can always shorten it. It is sheeted with 1/16" balsa, has upper and lower spars with two wing joiners. It now carries the SP - special performance designation.

Here are some photos of the build and some flying video from yesterday.

I still have some trimming to do and graphics to add....Continue Reading

Pulled this one out of storage and re-fitted it with some modern gear. I think this was my first glider build, and what I learned on, using an Aero Sport 2 transmitter. So it flies again 30 years later.... and I am still waggin the tail all over the sky. This kit has a dowel for the L.E.

I have had this one since about 1983. It has spent most of it's life waiting to go flying. I got it back out of the box and put some new radio gear in it to fly it again. Just like having a NOS plane since, if I remember correctly, it only flew twice in my teens. If I get ambitious I might take the old servos out and replace them with something smaller so I can install the cockpit. I also made up some carbon fiber pushrods. The balsa rods were showing too much flex. I set the powerpod on there just for fun.

Predator 3 Tests 4-14-12 (3 min 26 sec)


- Build Photos below -

The Predator 3 made it's way off of the workbench last week and has been out for a few test flights. This is my first 3 meter and V-tail glider. It is marketed as an affordable entry into the F3F world. When I was researching this plane I didn't find a whole lot of information out there on version 3. There is quite a nice thread on the V1 on RCGroups and some, on the changes to V2.

Assembly was pretty straight forward once you determine "the spot" for your fuselage gear and ballast tube. The P3 differs from it's predecessors by using a different wing construction technique (aviogate) and the continuation of the flaps all the way to the fuselage. This one is a single carbon version and I am using MKS servos throughout with 3rd bearings in the wings.

With the recommended settings I found this to be really sluggish getting those long wings around in a roll. A few tweaks here and there and it is starting to come together. I have also upped the rudder deflection quite a bit, coupled at 57%. Aileron throws are +10/-7 and flaperons used in both directions. I have played with the CG from 107mm to 115mm. At 115mm the elevators faired with the stabs but it was a little twitchy in pitch. Trying to find what works, on one flight at 115mm, I had it break loose in a tight right turn and it spun. Since then, I have backed the CG and some of the throws off a little and I am currently at...Continue Reading

I picked up a RCRCM Typhoon awhile back and have been flying it alot lately. It is really a nice flying 2 meter glider. There is quite a wide speed envelope and I have flown it in 5 mph winds up to 40 mph (that can be a bit too sporty for me). Here are some shots from the build and a video of the maiden flight. Hyperion digitals in the wing and Hitec digitals in the fuse. Things get a little tight under the deck with all of the wiring. Photos are of two different consecutive builds. CG at 95mm.

I have had this 42" SOS for quite awhile and over the past few weeks got it finished up and maidened today. Winds were 9-12mph and generally pretty good for this slope. Other than a few clicks of down trim it flew off and started tearing up the sky. CG at 4" and weighs 16.3 oz. I got two flights in with this one today and look forward to many more.

Here is a short clip of it flying and some of the construction photos.

Took the Super Cheetah and a flying wing out yesterday for some more fun. Wind was not as good last weekend but still flew them both. These like the other slopers, have been sitting for 20 years and needed a little prep time to get them going again. I knew I was saving all of those 72mhz receivers for a reason. Before any heavy refurbishing, I just wanted to fly them again. Nothing fancy, just some upright, frontside flying. Still playing with the CG's on these. The S. Cheetah was flying at 4" here but still felt nose heavy. The wing wound up back at 20% MAC and still needs some adjusting/flight testing.

I would like to cut some new cores and balsa sheet the Super Cheetah. Anyone know what airfoil it uses? Edit: I found it on the outside of the box E-374.

After such a great time yesterday, we took the planes back out for some more slope action. Winds and lift were great this afternoon. By the end of the day, Junior's Turbo was was putting my Dragonfly to shame with it's high speed groove tight on the hill. Both planes are really close in planform, size and weight. The wingerons on the Turbo are just too cool.

Went old school yesterday. Broke out the Dragonfly and my friends Turbo for a little slope action. Both of these planes haven't flown in 20 years. Nothing too fast or radical. Lift was okay to keep them up but not enough to get them up to some sporty fast flying. Maybe we will try again today.

After the loss of my first airframe, Ghost Rider was assembled. Maybe a little corny but it shares some parts from it's predecessor so I thought the name was fitting.

At any rate, version 2 got a few more mods than it's blue nosed kin. These include a full set of gear doors, retractable tailwheel, gear sequencer and functional radiator exhaust. Maiden flight accomplished on Saturday morning. Powered by a Scorpion 4025-12, APC 16x10 and 6s 5000mah 30c battery. 11 pounds 3 ounces RTF.

This was a time consuming build. Painting 1" checkers in white, and alternating, matte and semi gloss black on the fuse left my eyes crossed but I think it came out looking pretty good.

Here are some of the highlights from the build.

I guess it is blog entry day. I picked up a FJU and recommended powerpack a couple of months ago. This plane is alot fun. This entry is to highlight some of the things I have learned over the past two months never having flown one before. Maybe you will want to give it a try too.

In the Beginning... The kit has a low parts count and goes together quickly. It literally takes more time to apply the decals. Motor and ESC install are also easy. I used HS-65MG servos and they were a drop in fit. The first flights were eye opening at how well the plane retains it's speed in the pattern. Plan ahead if you want to hit your landing spot. Once you get the thrust angle set on the motor mount it is off to the races. I am not using the recommended larger mah battery. Instead I am using 3s 2250mah 65c packs that I already have. They work well with the recommended motor/prop combo but flight times are shorter. E-Meter readings show 745w, 70.82a @ 10.52v.

Time for Tweaking... I normally don't use the brake programming on the ESC but found myself using it on this plane after the first 4 flights. I also added a programmed mix to the ailerons slaved to the throttle stick to compensate for torque. This allows the plane to remain wings level when accelerating/decelerating quickly. The plane can be flown without expo or rates programmed. It becomes touchy at higher speeds however so I went ahead and finally programmed the radio last week.

Time for Dialing it in......Continue Reading
