Video Clip: Manta vs Mustang.
This was taken on the slope near Volksrust in South Africa a few years back. The lift was perfect with the sun behind us. One of the best days I ever had on the slope. The video shows my P-51 Mustang foamy and another slope flyer’s Manta flying wing. Clipping other planes is not uncommon on the slope, but sometimes it can mean flying is over for the day...

While flying at Court Lane with the Concord Model Engineers, I was impressed by the F-27 Strykers that some of the guys were flying there. So, when I got some cash for my birthday, I ordered an airframe without the radio/motor etc, and built it up. I maidened it on Friday, using a Mega 16/15/7 that I used on my wiffle bat plane, which never really performed all that well. I do have a 4-turn from the same series on order, which should arrive this week. The first picture below shows the plane as flown for the first time. It had surprisingly good performance, but it's clear that the motor is not matched to the plane.

After trimming it out, I decided that it needed to have tricycle gear attached to make it complete. I'm not really trying for speed with this plane, or I'd just leave the gear off. And the gear wouldn't be much good unless you could steer it.

So, I mounted small rectangles of light ply to the bottom of the airframe as shown in the second and third pictures, with a tailwheel bracket on the front. Then, I drilled 1/16" holes through the break in the fins straight down through the lite-ply. To attach the piano wire to the airframe, I cut the fin about 3/4" toward the front and dug out the foam to make a place for the wire to be glued in. After bending the wire for the wheels and bending the top to fit in the recess, I used epoxy to attach the wire to the fin, while drawing down epoxy into the fin and the lite-ply. Bending the wires to make...Continue Reading

Here are some photos of me flying the Tiger Moth while it was on world tour, it was some time ago but I just came across the pics again and realized that I've never posted them. This model was just in a recent issue of fly RC (it was a small photo but I think I could even see my signature on the plane!......everyone who flies it signs it) I believe the TM is still "touring" the world, I'm not sure, I know when I received it it had already been to like 40 something people, most of them in different states, I was the only pilot to represent the state of Rhode Island. It was allot of fun taking part in this project!

A great day for flying. Did a little Friday night, but got a couple hours of flying today.
Great thermals (?) today. Got like 20 minutes plus out of each battery.
I used the motor to get up as high as possible, then killed the motor and just floated around.
I was having a blast. I got in numerous loops, AND, did numerous inverted runs.
I'm stilll trying to get the inverted runs to last longer, but with up is down and down is up, etc..., it's kinda hard just starting out.
I went through @ least 6 batteries worth of flying.
I was @ the field for @ least 2 hours.
I did break 2 props, even with the prop saver, but both were stupid mistakes.
The first was hand launch and my hand caught receiver input and pulled it from receiver. DEAD FROM THE GIT GO! WHAM !!
The second, I accidentally hit my trim adjust on my radio to complete down and when I launched,
well you can imagine. STRAIGHT INTO GROUND !!
My neck is killing me from looking up for a couple hours,
but it's worth it.
I got some video, but again the frame rate is slow on the Aiptek SD.
10 fps makes it really j-j-j-j-jumpy.
Well later all, Happy Flying.

Another entry and another wreck to report - version 2 of the Blink was lost last weekend when the wing came off in a shallow inverted dive. I don't think I will be using magnets to hold any more wings on.

This is the first design-related crash I've had; usually I forget where the ground is and plow right in. The wing detached right in front of me about 40 feet up; I just watched it flutter down as the fuselage darted into the ground in the corner of my eye. What a shame since it was really flying well.

The wing survived and the fuselage didn't look too bad but there was a lot of damage:

Prop - broken.

Motor - melted internal adhesive (like the other ones) and impact damage.

TP 2S 730mAh pack - heat shrink torn and one corner bashed in; subsequently disposed of.

Berg 4L/Lightenna - antenna ripped off, connectors bent

Blue Bird 303 servo - bottom of case torn off by wiring as the wing detached.

I think I will try holding the wing on the next one with nylon bolts.

49 flights so far

The EasyStar is one fine airplane - still lots of fun.

Beautiful flying at dawn today. One flight was 20 minutes long. Shortest was 22 seconds - when I tried to do AP with a dead battery. See http://www.cs.southern.edu/jbeckett/...hortFlight.wmv for a video.

I was grateful for a field where you can land safely just about anywhere you can see. Suggestion: Always launch where you can get enough altitude to circle before you run out of landable space.

My wife is learning how to operate her new digital camera, and got some good pix out at the field.

I'm also attaching pictures of my AP setup. The camera is an Aiptek MPVR, which sits nicely in the cockpit. The only adaptation of the camera is using two plastic "peanuts" to hold the door open so it doesn't shut off (see somebody's comment about this before you do the same thing). Beware when you slip the camera into position: 1) The focus must be on "group" (wasted two very nice flights on that misteak), 2) If you bump the mode button on the back you're likely to end up in digital-zoom mode (another couple of flights down the drain.) The camera is held in by a piece of 3M strapping tape.

Earlier I was adding an ounce of lead to the tail to keep the CG where I thought it should be. Surprise! Today I forgot to put that on and it performed better. So we'll be an ounce lighter in the future.

What's this, a WMV can only be 100 kb? I'll have to put those things over on...Continue Reading

Lesson for the day: the smallest detail can make the difference between a nice day of flying, and a dark, lonely and sad moment...

Today the rain finally stopped, so I decided to let the EZ Star feel some fresh air, and try to take a few photos. Took off with no particular problem, but after about 30 seconds, I heard the motor do a small glitch, then went full power again. Oh well, I didn't really worry, and quickly forgot about it. I'd better have landed back right away...

Started to shoot pictures and pictures, trying to get something new into the view, maybe the forest with the cherry trees that just turned white. I also wanted to check the new mix I did, that would make the plane glide right after engine cutoff, and not dive like it was doing the previous flights. It seemed to work.

Then I realized that the plane was going in a direction that was not the best, and I wanted to make it turn back, which it didn't. Probably a lot of wind up there, I thought. Well, after a few seconds it didn't change its course at all. Sweat started to pour, as I tried to put full power, but silence was the only answer, no motor noise whatsoever. I tried frantically all the controls, but the plane was gliding slowly, doing a perfect, slow left turn. I turned off the radio, then on, to no avail.

As you can see in the pictures, the area here is really full of trees. After about what seemed an endless minute, the plane disapeared right in the forest. I ran to the road, and walked,...Continue Reading

After some shameless bragging about my wonderful new car, I thought I'd post my latest R/C stuff. About 4 months ago, I got a set of prototype cores from my friend Chris Klick at Ritewing RC. I finally got them done.

He's been developing a new sloper that is supposed to be an "all-in-one" type of plane that will handle light lift well, combat, be reasonably fast, agile, etc.

Overall, he has succeeded in my view. The wing is a relatively high aspect ratio planform with moderate sweep and washout, and a nice lift airfoil.

The flight tests are more than favorable. Although it's definitely not a halfpipe competitor in the overall speed ring, it is faster than your typical "slayer" type of combat wing. Roll rates are normal for this type of plane, inverted is simply excellent, and the low speed handling is very slow and stable. But most of all, it turns harder than virtually and other wing I have flown. With the right technique, it can bang a turn incredibly fast.

Below are some pics. I had some wrinkle hickups after adding thinned goop over tyvek (BAD experience), and ended up being forced to use transparent monocote. So, its not the prettiest thing in the world, but if flies great.

I'm normally not a blog type of person, but I just got an RX-7, and I wanted to show it off. I recently found out that the clutch is slipping on it, but I got an amazing deal on the car, and by all accounts it shouldn't be prohibitively expensive to fix.

The car is in very nice condition, with the original paint being in decent shape (rare for a 20 year old car). It has a couple of very minor dents, but nothing you can see from 10 feet away. Plus, it has a rebuilt engine and many new parts.

It has been upgraded everywhere. Racing wheels, straight back racing exhaust, port and polish, K&N intake, aftermarked steering wheel and shifter, high wattage stereo....etc....

This car is so much fun to drive. Handles awesome, and pulls hard at freeway speeds

The Nell has a distintive tail assembly and unusually finely tapered high aspect ratio wings. This bomber made 1600 mile round trips from the Marshal islands to Wake Island right after Pearl Harbor, and bombed it into submission for the first defeat of the U.S. in WWII. The successor to the Nell was the Betty which was vulnerable to fuel tank punctures and fires. It suffered high losses....Continue Reading
