David mentioned after his maiden that the engine cover gets very warm and needed heat shielding. I added three coats of BVM heat shield but it didn't completely prevent the fiberglass from getting hot and the paint from bubbling. This morning I went to Home Depot and purchased a flame protector heat shield blanket plumbers use and lined the inside of cover. The heat shield blanket is effective up to 2500F or 1371C. It took two blankets with some left over to cover the inside of the cover.

Kirk, which product you use to install flame protector?

I am sure there are other methods for attaching the flame protector material, but I use BVM ceramic heat shield. Simply paint a couple of coats of BVM ceramic heat shield to the PC-21 engine cover. While it is still wet, press the flame protector in place and let the ceramic heat shield dry. So far this method has kept the flame protector attached to the engine cover.

Other than the deflection of some intake air as detailed earlier there must be another way of getting some cooler air into the power compartment. The venting of air out of the fuselage at the back together with a few more NACA inlet ducts in the cowl could help. Or not?

Hi Nev.
Have a look at the picture of the full-size next to the spinner at about 8 oclock. I open my scoop there as well on the side and it makes quite a difference in temp with scoop open and I am also going to put the vents in the rear of the body like Scrogerio di in his. I will post a pictures when home. Hope this helps. Have you received yours yet. If you thought the hawk flies well wait until you put your hands on this baby. Send pic of you build and enjoy.
Have a great day
Regards

Thank you very much.
I don't have access to a paved runway, so grass is my only option, so I was thinking that keeping the weight as low as possible was the best path to follow.
I would likely skip the cockpit and pilots.
While searching the web, I did stumble across a PC-21 from Kingtech Luxembourg, JMB Jets, which is slightly larger than the Skymaster but significantly lighter (14kg wet) but it is all built up/balsa construction. It was flown at JetPower from the YouTube videos I came across.

Thank you very much for taking the time to help
I was planning on using the JetCentral Turboprop
It weighs about the same as the K60TP with a bit more power (new SE is 9kw compared to my previous version which was 7kw) and slightly lower fuel consumption. Also has Jeti Telemetry integration available....Kingtech has no scheduled date yet for Telemetry
The Swiss scheme in the video is my favorite and likely what I will be ordering
Probably going to go with Details4Scale lighting kit, no cockpit or pilots.

can you show the bottom scheme?
Is it black/white like the full scale?
