I have had some of the same trouble with the OrangeX 3-axis and my AR8000. I'd be interested to know what you did to iron out the problem. The powersafe was the thing?

This technique is the result of a frustrating 3 days spent with 2 Guardians and multiple receivers. The issue manifested itís self when the Guardian was plugged into my AR9110 PowerSafe receiver during programing though a PC. In 3D mode the ADI (Attitude Indicator) would lock up and not move regardless of what I did with the model. Manual and 2D seemed ok. By doing all of the setup on one of my other receivers and making sure I booted up and shutdown in the manual mode I got this thing to work with the AR9110.

I hope this helps.

Very interesting. Doesn't help my problem, but gives me some ideas. Thanks!

Thinking about my next project, I need to change the way I build the fuselage. The half shell method I used works fine as long as I have an 8-foot long perfectly flat table. I never found one. What I had was a reasonable flat 6-foot table. While the fuselage did turn out well, it was a nightmare to keep it straight. Next time Iíll use some sort of jig.

Any ideas on what model you are choosing to build? An X-24B would be cool with a v-tail.

The X-24B would be an interesting subject. Currently I'm starting preparations to fly the X-2 at Balls this year. It looks like I'll have Gorilla Motors make the K-470 without the tracking grain. This will prevent the tail burning issue I had last year.
I did send an inquiry to the CTI folks about inhibiting the tracking grain and never got a response.

Coat the tracking grain with grease or make your self a plug.

Coating the full sized tracking grain with grease in this motor my not be effective as this motor burns for 5.8 seconds. Currently Jim Harris of Gorilla Rocket Motors is going to make me a propellant liner that is shorter than the original by the length of the tracking grain. He is also going to make a spacer that will go between the forward closure and snap ring to take up the space left from the shorter liner.
The Gorilla motors are really nice and I have enjoyed flying them!

In the next few weeks Iíll pick up the X-2 from R/C hobbies to get it ready for Balls.
I need to repair and repaint the tail from the tracking grain issue. This years improvements are a motor with no tracking smoke, an improved nose gear shock system, improved main skids, a newer iPad to help with the telemetry dropout and magnetic retention of the nose gear hatch instead of the friction fit I used last year.
Iíll use zip ties on the cameras and that will eliminate the masking tape showing up in the video from the forward facing camera we saw last year.

I got the X-2 down from the ceiling at RC Hobbies last week and have started to prepare it for its flight at Balls this year. The first project was to evaluate and repair the burn damage from the tracking grain. While it looked bad, Iím pleased to say that it wasnít as bad as it looked. I used a wire brush attachment on a Dremel to remove the burned wood. Most places the damage was only 1/32 deep with a few spots as deep as 1/16. Anything that I do will just be cosmetic as the structure looks great.

Thats good to hear. You night look at cutting out a thin piece of aluminium and laminating it onto the rear with an insulator between. Might save you the trouble of getting special motors.

It's interesting that that the burn extends up to the rudder.

While Iím trying to keep the weight down in the tail this is not a bad idea and I may do this if I canít get the motor without the tracking grain.

With the intense heat from that hockey puck tracking grain I wasnít surprised the heat traveled upwards while the X-2 was gliding horizontally.

Last year when I flew the X-2 I had the nose gear cover friction fitted in place.
While this worked, it was not great as every change in temperature and humidity changed how tight it fit. I wanted something more consistent and predictable. I have installed some magnets in the wheel well and glued some tin on the hatch. Now the force required to eject the cover will be consistent regardless of the changes in the environment.

Not trying to be funny, but have you considered having two halves open on hinges with the gear down? Seems like a relatively easy mod.
