The smaller the better...

I'm going to make a bellcrank 90 degree. Put pins in both points so I know it won't have an advantage one way or the other. The one pin head will sit on the scales and the other will go in the nose of my jet. The jet will be suspended by fishing line at the CG . Zero the scales and then full power.
Should be an accurate reading.

Does anyone know where I can buy the IRLML6401 Mosfets? I found one place that wants $8.98 ea. Every other place I can find has a min. $100-$300 min order. hklam in an older post said Farnell's had them for .50 ea. Big difference. The link to the site doesn't work anymore

Appreciate the help.

Nice to know since I see sign vinyl plotters on ebay cheap quite often. They can also be used for printing. One of these days I plan to buy one.
I wonder if any of these cutters ( ) would work for thin depron. I read somewhere they can cut thin balsa (like 1/32in). Not sure if they are as robust as an industrial sign cutter, though.

Heya thanks for the tidbit Rick.......but alas!
It is a CNC laser.....
24x30 bed running off of corel draw
I have access to this at work, sadly it is not mine!
I use it for all my prototyping and then send it off to my elves in the forest for .manufacturing in-mass.

rdaggett77>>> After a few hiccups with the manufacturer (slight imperfections but this is the curse of the picky!) we are back on track....
the order to the manu. and materials should be there in less than a week.....

you have to use the right size of paper.
i don't know which size right on top of my head. I just let the printer picks out.

I cut it out then trace it on to-go boxes.

The Selfo SU27 is a good flyer. If you are able to fly, you have the CG close. Since there is no surface controls used on the Tx, alerions, elevator, rudder, it is common to lose some altitude when turning. It sounds like your CG is just a bit to far forward or you need to bend in just a bit of up elevator. A good setup is to get the "no power" glide right, next fly with abt 1/2 power. It should fly level, a little nose up is nice. when you turn, you will lose some altitude, the tighter the turn, the more you lose. Then just level the wings and if to low just bump the throttle a bit and it should gain some altitude back. If its not climbing under full power, I'd do both just a little and go from there.
