Unfortunately no speed readings, but atleast the variometer showed over 80m/s at best )))

Your thoughts on the ali plates are correct i have also noted this with other brand of batteries. It help hold down the puffing. Your plane must now be really moving @ 26000 prop rpm.

What size W x L x H are your lipos. From the specs on the internet i see that the W is 42mm and H 35. If that is correct how are getting them in their?

Just Squeeeeze them in. They are about 40x34 for a 5s with plates. Had to rebuild two 3s packs http://www.rcflight.se/visaprodukt.aspx?id=1589

Be carefull of lipos with Alu. plates. If the packs can't puff up they will split out the ends instead.

I received an inquiry about the control horns I made for my Avioniks, so I had my AutoCAD drawings converted to a PDF for printing and attached them below.

I made mine out of 1mm carbon fiber, but I'm sure FRP would also be fine. One will need precision drills to drill them the correct size for whatever pushrods they are using - test drill holes in scrap pieces first before cutting and drilling the horns.

Use spray adhesive to glue the paper templates to the horn material, then cut out. When drilling the holes, a drill press is almost mandatory as carbon fiber is very difficult to drill through - especially drill straight if you don't have a drill press.

When printing the pattern, be certain to set your printer to 100% or actual size. Measure the square to make sure you printed to the correct scale.

Needed to shorten one of the battery wires coming from the ESC in my Avionik, so pulled the motor. Had a look a the insulation on the terminal wires exiting the motor case and no sign of any wear after about 50 flights.

Everything going swell.

Hi Fatih.

In one of my Avioniks (and both of my Vipers) I use Hitec HS-65HB on the elevator:

In my two other Avioniks (one deceased now ) I am using Hitec HS-5065MG. I don't care about the metal gears, but I wanted digital:

http://www3.towerhobbies.com/cgi-bin...?&I=LXSDA9&P=7

In the Avioniks I am running 2S LiFe, but I have this regulator in-line for the servos:

http://www.soaringusa.com/Servo-Regu...-A-Inline.html
http://www.espritmodel.com/mks-volta...c-5-8v-2a.aspx

At first I didn't use the regulator - for probably 50 flights on the Avionik, but later I decided to use the regulator. No problems before the regulator or after the regulator, but I thought it would be best to be safe.

In the Vipers I use 2S LiPo, but with Castle Creations regulator.

Tim, thank you for your information. I took note.

I was thinking of Hitec HS-65HB servo for elevator use.

Thanks.
