Thought I would try this Blog...thing.
Been flying RC ...for about 6 years now. Mostly .40 -.60 size glow stuff. I have one 1/4 scale SIG Sukhoi with a 46cc gasser up front. Recently discovered sailplanes (electric powered). So now I am learning all about electrics. I am looking at getting something for the slope...but need to find a place. Too many trees around here. Added some pix of the rest of my powered stuff.

An older couple is lying in bed one morning.
They had just awakened from a good night's sleep.
He takes her hand and she responds, 'Don't touch me.'
'Why not?' he asked.
She answered, 'Because I'm dead.'

The husband asked...'What are you talking about? We're both lying here in bed together and talking to one another!'
She said, 'No, I'm definitely dead.'
He insisted, 'You are not dead. What in the world makes you think you're dead?'

'Because I woke up this morning and nothing hurts.'

I recently found a Sophisticated Lady sail plane that was given to my family a long time ago. It has the option to also add a motor to it. It can have a gas or electric motor. If i use the gas i need a .049 engine and i can't seem to find them anywhere online from a store, just on ebay, craigslist, etc... Does anyone have any suggestions? Thanks for any help!!

94" bolt on wing, larger rudder, and changeable nose to EP

Here's couple of pics from my F/A-22's first taxing and ROG tests. Weather was terrible, but I just couldn't hold back anymore. Temperature was -16 degrees and it was bit windy, so my Raptor got some taste on the conditions where its going to operate. Bit like the Raptors in Alaskas squadron

Before I wanted to trash my Raptor, I took my loyal A-10 trainer so I could check how the cold and wind affected such an open space. A-10 flew really nice, only on the final approach it dived pretty unexpecting.

Plane handled really nicely on taxing and all controls and surfaces moved with out any clitches. After couple of longer runs to check the speed and available thrust, I carefully pulled stick slightly back and Raptors nose raised and it took off gracefully and without any problems. Only adjustment was on ailerons, couple of clicks to right and it flew dead straight even in the wind.

On the second ROG run strong gust of wind threw the plane almost vertical during the take off but there was enough oooompf on the motors to get her on level light and to land safely. Wind just got stronger and stronger so I decided to call a day.

Today must be my narrative day :-)
I was just looking through the EagleTree logs of my last flights, when I found the one below.

The flight was on a sunny day, below -5° Celsius. There was a light but bitter cold breeze which let my fingers get stiff after about 5 minutes flight.
So I was in a hurry plugging in the batteries, do the preflight check and spool the bird up.

Before the last pack, I noticed the Futaba 9257 screeming like a rusty metal gear. I flipped the gyro switch on my DX6I to normal mode, in order to check the servos travel.
Damn, the travel to one side was making the servo buzzing. The cold must have shortened the steel push rod, so the pitch slider is now pshing against the tail housing.
I didn't had a suitable screw driver with me, but the binding was so less, would hopefully do not much harm to the servo. The screaming sound of the servo was only in one direction and I assumed some part of the servo gear wasn't properly greased...

Then I didn't want to waste another second of battery power, so I put the bird on the ground and spooled up.
During spool up the tail drifted away a little bit and I had to adjust with rudder input. When I applyed pithc to gently take off I even had to apply more correction rudder.
Damn, stupid me had forget to flip the gyro switch back to HH mode.
This was the first time ever I entered normal mode, for gods sake the tail slider was nearly trimed out for proper hovering...

Since the little disaster after my...Continue Reading

No flying today, its cold and rainy outside, and I stripped the aileron servos gear (HS65HB).
This cold have got nasty, since I did a dozen flights with the stripped gear before I recognized it.
The broken tooth was only in mesh if you applied full positive pitch and a bit of left aileron.
From this position I nearly beleive that I was flying with the broken gear since my emergency autorotation in mid october.

On that special day I was flying together with Ron on our favourit flying side the Leineweber ring, while some guys were playing rugby in the center of the racetrack.
So we had to be carefull to not disturb their game and we flew near to s, not so far away.
I was trying tic tocs and high speed half funnels (freightened to do a full circle).
Before the last pack I checked my tail, because I had some bad feeling about the new carbon tail blades I used. The performed great, the tail was always where I want it to be.
But when I checked the tail blade holders, one of them had much slop. I removed the blade and tightened the screw inside. But the screw someway felt strange.

After that, it was Ron's turn, he was just doing his first fine figure 8's and he was really happy.
Maybe too happy -
He landed, just to make a nice vietnam style take off (pushing much elevator and pitch and let the tail swing out due to the thrust).

The takeoff looked great but the following 180° turn was seemed much to fast for his current flying style.
The bird was dropping...Continue Reading

Made up a bolt-on penta rotor. It only takes 1 commute to convert between 4 & 5. The hardest part is rotating & realigning the IMU.

U might say it's payload on demand. U can't easily increase the payload of a unicopter without expanding the tail boom, but U can design a quad rotor to take bolt-on rotors.

Unfortunately, once again the penta rotor went nowhere fast. The longest flight was 4 min & that was with the battery always below the cutoff voltage for normal operations. GPS once again never locked, regardless of whether the ESC's were on. Suspect the carbon fiber arrangement is causing some kind of ground loop.

The connection of the 5th rotor did indeed wobble. The wobbling caused resonant oscillation with the rate controller. Spreading the weight more evenly between the 5 rotors may have increased flight time a hair. Now we're pretty sure the use of angled nacelles to defeat torque is sucking the power.

We can eliminate inefficiencies in inline propellers from the list of culprits in the penta rotor....Continue Reading

Kevin maidened his Superfly last weekend. (First plane.)

He turned up to fly this morning up with super lightweight chopper style aluminium skids on his Fly. Now he can ROG.
It's evidenced in the video :

I hatched out in 1958 and started making trouble for my parents right off the bat. That they put up with my antics without trading me in for another model says a lot about their lack of sanity.

My Uncle got me interested in building models when I was in the 6th grade. I started off on the old Gillows kits. You know the ones I'm talking about. Lots of sticks, a few formers and a tissue and dope covering with a rubber band for power. I soon graduated to 1/2a power planes and flew C/L combat for a number of years. I soon learned that I was dizzy enough without spinning in circles at high speed and switched to tow line gliders. Old Jetco models still hold a special place in my heart as they were great flying planes. (Even if you did have to chase after them!)

When I turned 17 I joined the Army and while serving in Korea I got back into C/L flying since we were not allowed to operate R/C planes. I built up a Voodoo and a Spitfire stunter and had a blast with them. I ended up selling them off because I didn't have any way to get them back to the states. When I got out of the Army I moved back to San Diego and got into slope soaring at Torrey Pines. Living about 35 miles inland from the coast I had access to several slope sites that were close to the house so I was almost always flying. This lasted until I discovered Ren-Faires. Beer and Blades and women all in the same place! What more could a guy want? I still flew from time to time but not nearly as much as...Continue Reading

Here is some pictures of my c-130 and 2 short bad videos. If your wondering the maiden went wrong and i had to get a new nose and fix the wing that snapped thats why its white in the videos. ANd the pictures were post maiden but it looks the same now. So enjoy~!

ANd it now has a dual nose wheel.

I've finally made some legitimate progress on the wing design. It's particularly difficult to design the center section due to the double sweep, and the fact that it is detachable. The attached screen shot shows the planform of the whole section that will be removable. There are some (many) details I have to work out yet, especially the formers to make this section blend with the rest of the fuselage. The 3 horizontal rods are carbon fiber tubes. The hardest part is figuring out how the thing will go together. Right now, the center part will be built first, then the next bit (the parts with the rockets) will be built into that section. Then the wing panels can be slid on to the carbon rods and glued. (I hope ) This plane is a real challenge for me.

One change is that there are only 4 instead of 6 18mm rockets in the wings now, for dimensional and practical reasons.
