Arrived at the local AMA field just before sun-up. Wind at dead zero, temperature a little below 70 degrees. Among other things, I tried out the SlowStick as an AP platform. It does indeed fly slower, but we get vibrations (presumably from the motor) that mess up pictures. I have little of this on the EasyStar. It must be a resonance of some sort.

Had a great day yesterday and met some folks from the forum. Left to right below is me, RCTyp, FlyingHigh and Safety Hawk.

Many thanks to Bildo Baggins for putting this event together.

Took the Stickler out this morning for its maiden flight, but didn't stay at the field too long.

From the first toss the model dived and rolled gently to the right, up elevator was not effective and it cartwheeled into the ground. Nose section was snapped off but no other damage.

I left the nose section off and repositioned the battery leads to get the CG rearward.

From the second toss the model climbed slightly and was very sensitive to aileron input - I over corrected several times, losing altitude each time, and the model nosed in again knocking the fan and speed control loose.

The second crash was very similar to the crash of version 2 last year, very twitchy in roll and not at all stable.

My plan is to repair the model and add additional area to the tail group & elevator for stability. Ailerons need to be cut down too.

I will get this thing to fly right!

Had the typhoon about a year now or close to it.. its a lot of fun to fly. ive flown it on 3 power set ups and the 480 was a lot of fun but needed the gear for my extra. its back to the stock power set up and i added some wheel pants. im pleased with the results.. makes it look more like a pattern plane. sooner or later i'll get a pattern plane/been wanting one for a while now/and probally will scratch build a foamy one from depron for testing when i have time.

Got a couple more flights on the extra today. half throttle snap rolls at 6 to 8 feet are very nice in calm air. its been fun in 10-20 mph wind but today in calm breezes it was a lot more fun.. it looked like i was watching a 40% plane flying around.. just smaller .

Went out to El Mirage this morning and test flew the Cassutt. Conditions were perfect, couldn't have asked for a better morning. I am extremely happy with the performance of the airplane, it handles well, speed is good and it turns very well. Took a couple of flights to get it the basic trimming and control travel adjustments done, then was able to simulate a race on the third flight. Cornering is excellent, will pull a hard turn with minimal loss of airspeed and is easy to put on a line. A real 'point and shoot' type of airplane.

It goes back in the shop now for some clean up and a coat of gray primer, then will be ready to race at Parker next month.

I have the honor of helping an old friend part with some of his planes, at the same time, I am trying to bring down my own fleet a bit.

Got the Scoot build up during the week and couldn't resist painting on two real big "invasion stripes" on the underside of the wings. Anyway, not being very experienced I had some tredipation about this one... Anyway, got to the field, and checked the throws were nice and easy, and gave her a good hard throw to check the glide. Dived in fairly abruptly, so adjusted in some up elevator trim, did a few more glides, getting smoother and smoother (more to deal with my confidence issues than the aircraft's trim!). Then after some gentle taunting by the wife, banged upon the throttle and gave her a good throw. On the stock power system, she climbed out nicely and - wow! - my first aircraft that an out and out powered ship rather than a powered glider of some sort - it's fun! Needs very careful management of altitude though, and she's not the best powered of aircraft, but that's OK - just need to think ahead a little bit. I think that the trims aren't the whole story though, as she climbs on high throttle with no up elevator, but when power is shut, goes into a bit of a dive which need pulling out from. So I think that perhaps she needs some downthrust which would enable me to remove some of the down trim necessary to maintain level powered flight. However, the only thing that's a little odd is that the elevator is visibly trimmed up already, with the CG bang on to stock settings. Incidence relationship? Not really prepared to go into that on an aircraft of this type, but I think that there's some experimentation and learning to be done by playing with the downthrust settings and trim.

But to summarise, very much easier to fly than I was expecting - easy really, but fun to see something moving along at a bit more of a rate than usual! FOr sure now I'm going to be practicing those fast low flybys! Definitely need to get that downthrust/ trim relationship sorted for that sort of caper!

Have a good weekend's flying all...

Zimodile.

Well I finally got to Mikes Hobby Shop in Oklahoma City.
Mike is a great guy and very helpful. He and his son are
very deep into 40% planes and competition.
I got to see the Aeroworks plane they're going to competition with.
Incredible! Very impressive.

Anyway... back to normal folks :>)

I bought the following
  • Wood for the servo tray
  • Paint
  • Monocote
  • Xacto Knife and blades
  • Incidence Meter
  • CA Light and Medium
  • 5 min. Epoxy
  • 45 min. Epxoy
  • 5 standard Futaba 3004 servos
  • 4.8v Receiver Battery
  • Aileron Hinges
  • Dremel 400 XP
  • Cold Heat soldering iron

Because my wife cleaned off the kitchen table and was not
home when I needed to leave for Mikes; I left without my well
planned list. As a result I forgot a couple of things. But they
are finishing tools so I can get them later.

I'm really looking forward to Sunday when my son and I
finally get down to the real work of building/assembling.

If anyone has ideas or suggestions for building the servo tray
I'm all ears.

I'm impressed. Nuff said.

As many of you know, I serve as the General Manager of Knife Edge Software (www.knifeedge.com), the developers of the RealFlight R/C simulator (www.realflight.com).

Knife Edge has been working quietly on a new release which is called "RealFlight G3.5". We are now sufficiently along in the product development cycle to let the public take a look for the first time.

RealFlight G3.5 will be a free update for owners of RealFlight G3. It is over 500 megabytes in size so it is a big download, but if everything goes as planned you should get it using the normal update process in the RealFlight G3 Launcher.

G3.5 adds nightflying, streamers, responsive collisions, 4D propellers, several new airports, airplanes, and helicopters, and a lot of little things that regular users of the software will appreciate.

One of the beta testers uploaded a video today:
RealFlight G3.5 (1 min 3 sec)


I'll be sharing some more information about the product in the coming weeks. If you have been a part of the beta program you are now free to post screenshots here at RCGroups and at other R/C sites.
