The postman brought two 4X8 sheets of .040" PETG, going to do some vacuum forming. Just installed a p&id controller on the oven, need to play around a little.
Ok Tony need all the details I just made cowl from balsa and covering it was a lot of worse and something I would not like to do again. I would love to know how it is done and the equipment needed. Thanks for sharing this part of the build.

All the equipment is home made. Here is the vacuum table, 1/4" plywood bottom, 1 x 3 sides and the peg board top, two shop vac's are connected in series to the table.
You need a buck to form the sheet over, this need to substantial, in my case I made the buck from a less than perfect canopy, this is going on a Bob Godfrey One Design that you may have seen in the back round of the Champ photos. The canopy was fitted in a wood support and filled with Ultracal 30 plaster, then glassed and sanded. The plastic blanks are 24" x 32", get six from a 4 x 8 sheet to give you an idea of the size.
The oven is two 1500 watt Sunbeam quartz heaters housed in packaging from an Aeroworks ARF, the fiberwood stuff that looks like Masonite. I will get photos of the oven when I do the pulls. Making a canopy for the One Design and a new canopy for the Champ, the canopy I bought for the Champ was Ok but not quite what I wanted so I bought another canopy and made a plug from it then glassed and sanded to fix the problem areas. I tried pulling a Lexan (Polycarbonate) sheet for the Champ last week but that turned into a mess, much more difficult than pulling PETG, pretty sure it would have been the bees knees if it worked. I broke most of the equipment trying to make the pull including damaging the plug. But hey I still have 5 - 24" x 32" Lexan sheets that I don't what to do with, I may try again once the dust settles from the Champ build. Will post the following photos in Champ build once I get the plug repaired

Ok it took a while but it eventually showed up. Now all I have to do is reprogram all the software for a plane. They all come pre programmed for a helicopter. Does not look to difficult but time will tell. After looking at the unit I have to order a bunch of connectors.
The one reason the unit was purchased is because you can program the the size of battery being used and set the amount to be used from the battery and then set a motor cut to a percentage so that you know and can land, no more timers and you use the correct amount from the battery every time.

Keep looking at the second picture not sure I am getting it. Is that a failed attempt and the material split off the end.

Really doing well with the postman the batteries showed up now that was quick. They look good but the balance leads are way to short really doe not like the length. Will be doing some testing on them tomorrow to see how good they really are. Will see how they compare to the 75c graphene batteries. Should prove interesting. Did a lot of research before they were perched so let’s see how good they really are.
