Not a lot has happened this week as I’ve been occupied with other tasks, I did install the ESCs, 150 amp/180amp burst. A nice feature is the plastic clip to mount them with instead of Velcro.

Slowly the planking progresses.

Hello everyone, I hope you all are finding something to do with your home time.

 

This week I finished planking the top of the airplane, now I’m going to take a week off from planking to work on some other issues.

 

When the virus lets up if anyone wants a lesson on sanding curved surfaces I’ll gladly help them out.😁

Just arrived, the plug for the canopy and turtle deck, perhaps Monday I’ll start the process of waxing and buffing to prepare for the fiberglassing. I’ve never fiberglassed with a plug that you pull the part off. What I've done always in the past is to shape a foam plug, fiberglass it then melt the foam.

Here is one of the new Behotec struts from Altecare in Mississauga Ontario,  very nicely done.

 

I’ve started blocking in pink foam on the bottom of the fuselage, pretty much the same as the top filling in where it has too much curve for the planking to bend around.

 

I’ve also started waxing the canopy plug. First I taped up areas where I wanted the excess fiberglass to end on and started a process of waxing then buffing the plug. This will happen 8-9 times to make sure any surface issues are filled and smoothed. After I’m happy I’ll start laying on multiple layers of fiberglass. The blue tape should ease the initial release of the part from the plug (I hope).

This afternoon I sprayed the cockpit plug with several coats of PVA (Polyvinyl Alcohol - a water based mold release), after it dried for a couple of hours Glynda and I placed three layers of 3/4oz. fiberglass cloth on to the plug then rolled toilet paper over the plug to absorb any excess epoxy.

 

I’ve placed an order for some soft drape 4oz cloth to speed the layer building. But in the mean time we will put a few more layers of the light cloth on until it arrives.

I had been planking using SIG Bond, a yellow glue. It works well except for one issue that’s a pain in that it is very hard to sand flush with the planks generally leaving a thin line of hard glue just proud of the planks.

I turned around and went old school on the bottom of one nacelle using Sig-ment, an old school model airplane cement out of a tube, similar to Ambroid. It glues well and sands easily but is a mess to use. The glue builds up on your fingers until finally you have to stop and peel it off.

 

The fuselage bottom planking is waiting on a new nose strut, seems I ordered the first one too long. 😞
