skymaster pc-21
#327
I received a set of under wing tanks for the PC21. Has anyone installed them and if so what mounting points did you make up in the wings to install the pods?
I noticed the L/R pods are angled slightly on the wing side, I assume it is to make the pods hang vertically due to the dihedral of the wings?.
Anton?

Nev,
I think your assumption is correct - that has been my experience with other SM wing tank pylons. Just a word of caution with the actual mounting positions; whilst you may find hardwood in that position, you can never tell if you are maybe on the edge of it or not. I normally open it up (round 19mm hole) and glue a 19mm round dowel up to the top wing skin. I then drill and put a plastic wall plug (like we use to hang pictures with) in the correct position on the dowel and use a long wood screw to hold the pylon on the wing. The screw head is countersunk into the pylon so that it does not interfere with the tank. Everytime I fit the pylon, I first turn the screw anticlockwise to 'feel' for the thread that the screw had cut into the plug. That way you don't cross-thread the plug. This method allows for an easy 'pullout' if the tank should ever get caught somehow and will then not 'break out' the pylon mounting in the wing.
Cheers,
Jan

Thanks Jan, seems I will go that route. There are no hard points in the wing I believe. Would be nice to get thoughts from the manufacturer of these kits, but anyway your method makes good sense, will try to see if I can "tie" the dowel to a rib that hopefully is in the area under the skin.
Btw it flies very nice. .

I finally flew mine last week. Two perfect flights. On the ground, the KT60 pulls like a mule, feels like way too much power. It doesn't translate to the air... static thrust versus actual thrust in the air??? It flies very scale like with the KT60, if you want a hot rod, I think the KT100 is the way to go. The 5 bladed prop sounds amazing. I just need to get some smoke on mine and it will be good to go.
Landings are awesome, slows down to a crawl. When you put the turbine to idle, its like throwing out a boat anchor with that big disk up front...drive it down and flair... Definitely a keeper!

Hi Anton,
Have you flown the PC21 with the wing tanks attached? If so were there any major trim changes.?
BTW your diagram measurement for the rearward attachment points is perfect if you want to end up right over the edge of the retract frame and cylinder. Sometimes I really believe your rulers are different to ours....

Hi guys I just picked up pc with a k60tp, the previous owner was flying it with a 3 blade carbon fiber prop without the spinner, personally I don't think it looks very good without the spinner. Question is I am trying to add the spinner with the skymaster 5 blade prop, but once I add the back plate there isn't much room left on the shaft for the prop to sit on securely. I am not very comfortable flying it like this, is this normal? Thank you

Mine is the same way, seems to work fine. I had trouble tightening it though, piece of adhesive sandpaper on the back plate totally solved the problem. 5 blade sounds SOOOO COOOOL!
