JARTY Questions

Having built and flown my 1st composite JART, not only does it generates a big smile on a face, it looks like it is flying significantly faster than I thought it would.

I'm busy with JART #2, but was wondering what speeds they are capable of?
Has anybody measured their speed, and at what wind speed?
This time I'm looking at split wings and the re-inforcement to cope with the stresses on them.

Also, do you use 4.8V or 6V packs?

Cheers

Agulhas Jart Flying

Here's some flying video clips of my first JART attempt. (51 oz AUW).

I'm flying in a loose circle with a diameter of +/- 700m. The flybable slope in a South Wester is around 2000m. The video clip is not representing the actual speed, as at times, the JART just outran the camera.

JART Launch: On launch it shot up to a dizzy height while gaining forward speed.

JART in flight: Some seagulls gave chase, but it outran them. Once it gained speed, it is greased lightning.

"Take us to your leader, we want to build JARTS on Mars too ...."

I'm now building JART #2 - it will have some minor tweaking, based on experience gained with the first one. All in all a very nice plane to build and fly.

Friday arrived with a moderate South Westerly wind at about 20 Km/h ( note the lack of white horses in the background!) We decided to toss her anyway and managed to trim her up in flight. The aileron throws need to be readjusted as the roll rate was nowhere near the old Jart. Wind strength did not help much either....

The main thing is she flew, and we'll put her through her paces soon!

Red Bull Jart

I know, I know....... just another Red Bull plane that" gives you wings"!
So what, I enjoyed building it and the stickers were lying around. The process also taught me the art of spraying and masking! I must have sprayed the three colours six times and taken it down as many. We are just waiting for a strong south westerly!
The plane weighs in at 1150 grams fully loaded and is perfectly balanced. I have given Alain my old one as it has had a tough life. It's been crashed and flown hard and still flies beautifully!
I must just ensure this one lasts so that we can take it along to Hermanus in November!
As Daron would say, YOU HAVE TO HAVE ONE OF THESE IN YOUR QUIVER"!
