Yesterday I saw a picture of the assembled rotorhead, when I compared this rotorhead with the parts on the drawing I discovered some differences. photo 1: Part HD3, distance to spindle mount center is 35 mm. photo 2: assembly drawing, distance to spindle mount center is 30 mm. photo 3: assembled rotorhead, distance to spindle mount center is approx 25 mm. Photo 3: by David Ashby Edited By Koen Smits on 10/04/2013 08:40:02 Edited By Koen Smits on 10/04/2013 08:40:44

Hi all, Thanks for the helpfull reactions on my question about the crash on maidenfligth from my panther. I think the most difficult thing will be to put aside the fixed winger in me as Bill Pettit wrote. Thanks Koen Edited By Koen Smits on 08/04/2013 21:21:08

Hello All, Today we had super weather to maiden my panther, but the first attempt wend wrong. As soon she was off the ground, she rolled to the right and with a damaged propellor and 1 blade, so the party was over for today. Maybe the experts are able to tell what possible caused the crash and give advise how to avoid this next time. 2 short video in the links below **LINK** **LINK** thanks Koen

Posted by Kevin Howard on 21/03/2013 15:24:30: Koen, I was also thinking of buiding a Panther. I have access to a laser cutting machine and wonder if I could have a copy of your DFX files, save me drawing them out. Regards Kevin Sorry Kevin, Because of the fact, there is a copyright on the drawing and i think also on the design of the panther and i don't want to get involved into copyright questions, i can't give you the dxf-files.

Andre, I suppose you fly electric and i see the rudder servo is placed in the tail. My question is, how much extra weight ( lead) did you have to put in the nose to balance on the CofG point? Because i need to put a lot of weight in the nose to get CofG ad the right position as i wrote already about 3 pages ago.

Hi Jose Luis, On page 22 of this tread Andy Nash posted a couple of pics from his sanding jig, they where clear enough for me to make use of the same principle. I used for the sandingblock only ply, it's better to use ply and aluminum as Andy did. Koen

My blades befor covering. After covering, they are black at the top side and white at the underside. In the square is a small piece of oracover glued, neccessary to get the weight equal again. All 4 blades are 48 gramm after covering The blades i sanded in a jig as Andy Nash shows some posts back. Picture of my sanding jig. Control rods as they are on mine. Picture from the blade balancer Aldo i extended the nose, to get the lipo in the batterybox, with 3 cm. I have to put aproxx. 190 gram lead behind the motor to get the Panther balanced. To save weight i used already 4mm balsa for the rudder, The uppersides 2 mm instead of 3mm To balance i use a scale and some math to find the CofG at the moment of weighing and the with a little math you know where and how much weight you have to ad or substract.

John, Try to get all 4 blades to get the same weight, by sanding off some on the heavyer one or attach some weight at the span- and chord CofG position. Read PT balancing act on page 16 RCME April 2013. I will post some pictures his evening. BTW The by Richard designed blade balancer is or to small or drawn on the wrong format, A4 instead of A3.

Hi all, This morning i made a testrun to vac form the canopy. The plug i made yesteday Balsablock After some schaving Schavings Vac formed Trialfit The form from the plug is oke. As you can see, on the last picture, the plug is not smooth enough you can see all the details from the grain and the seam between pieces of balsa where they are glued together.

Posted by Andy Nash on 20/02/2013 21:42:30: Getting the correct angle. The measurement from the top deck (where the CofG is marked) to the pitch control screw is 208mm. I hope this helps Regards Andy Edited By Andy Nash on 20/02/2013 21:45:26 Andy, To set up the correct angle you measured 208 mm from the decking to the center of the pitch bolt, What is the measurement from the decking to the center of the M5 swiveling bolt ? These 2 measurements are both importand also the distance fram the pitchbolt center to the swivelingbolt center.
