Hi Brad - that li'l Gem looks really good  Smiley  - I may have to convert to peanut scale models myself - no more room for big models - will the Gem Racer be Free Flight Rubber Powered ?  They must fly just as well as the big models - right? - and take less time to build ...  Wink

Old school landing gear attachment with thread  Smiley  I'm pleased with the mounting.  Also a couple of shots showing how much I enlarged the rudder and elevator.

I got the wheel pants put together and trimmed and sanded to shape.  I'm thinking of using the wheels in the photo.  They aren't the lightest (although I think they are called ultra light or something close to that).  Another idea is that I will cut one in half and only use 1/2 wheel per pant.  It will be a non-functioning wheel, but cut weight.

I'm also starting to work on the front.  I didn't have any 1/32 sheet on hand, so I spent time sanding down a 1/16th sheet !!!  It worked, but not perfect and lots of effort.  I'm also starting the under nose area.   Don't ask about the hole in the bottom sheeting - for some reason I thought I need it - ops.  I do need to work on the landing gear as well.  I have the wire bent and just need to figure out my install/mount.

Just about any wing can be built using the cracked rib construction Bob.  Just use turbulator strips between the spar and L.E. on the ribs from root to tip as desired for rounding out the airfoil. (But the F-117 showed the triangulated airfoil will fly fine)
You can vary the turbulator strips in size from 1/16" sq to larger sizes.

My fuselage came together well yesterday.  It's fairly straight compared to my usual and seems strong and light.  I started to cut some turtle deck formers so that will be next.

"Little Gem" racer

I've started to build a "Lil Gem" racer.  After my last build this was the simplest plans I had on hand, plus I love racers, so here I go.

It seems that there are many different planes of this design.  Ole Tiger, Miller's Lil Gem, ???  I'll do some research as I build to figure out how I want to finish it out.

My goal for this build is to build LIGHT!!  My tendency is to brace/support and over build for strength and my planes are always quite heavy.  So far so good.  What I've built is lighter than anything I've previously done, so I just have to keep it simple.

I did a cracked rib approach on the wings - that' nice and quick!!
