Cool, I helped build the 40 version and it was a fun project. Flies great in the air also! Good luck on your Tiger 60!

Well I have a set back. I went to glue the stab together and when I put weight on the parts the table bowed. Ok so build on hold till I have time to get a proper table put together.

Day 2

I picked up a 2' x 4' x 1/4" mdf and covered it with the steel sheets i had. Worked like a charm. I tried making some magnetic fixtures with some 1/4" ply I have. I only have an orbital saw and that made a mess. Maybe I can beg santa for a table saw .

I used tight bond to laminate the laser cut center parts. However when I went to sand the glue, the underlying balsa ripped out when the glue balled up. I dont know what that is all about so I completed the stab with CA.

Finished horizontal stab:

I built one of these as a tail dragger two years ago. Powered it with a Magnum 91 4 stroke. The thing flies great. It's kind of tail heavy in this configuration, but it you make the platform the fuel tank sits on removable, you can use the space underneath to put in weight or your receiver battery to balance.

Titebond doesn't sand well.... however it sounds like you started sanding before it fully curied. To avoid this, have a small dish of water and some paper towels. Quickly wet the towel so it's damp.. not wet.. and wipe off any excess glue from the joint or where you don't want it. No sanding of glue off unwanted areas will be required when dry.

Elevator done. Had to load up the joiner dowel with epoxy mixed with lots of milled fiberglass. Otherwise the joint kept cracking when pressure was applied.

Your Tiger is looking good Aerofly! I am also building a Tiger 60 that i started two weeks ago. It is a great kit so far. It sure does take lot of time for an inexperienced builder like me to get the fit right. Good luck with your project and keep posting those pics, they sure help me out with my build to be able to double check how things should go. I already screwed up my horizontal stabilizer and had to order some more balsa.

How is your build going Aerofly? With your weather it may be spring before you get her in the air. You can take your time and enjoy the build. I decided to slow down on my build. I make too many mistakes if i power through. I have finished the tail section and I'm happy with the way it turned out. Now onto the first wing panel. Well maybe next week.

Day 4-5

Well last weekend was just awesome out so I had to go flying . This weekend is rainy and windy so build day eh? So im about 30 minutes into working on my vertical and rudder,,, and my propane heater runs out . 40*F is just a wee bit cold to be building for me . Ill get back to it once I have time to get my tank filled.

I ordered my covering. Coverite (cant stand monokote anymore) orange and white. Bottom will be white and top will be orange. I may wrap the orange around to the bottom. Then Ill try my hand at cutting tiger strips in black. Never done anything fancy like that before. Inspiration -> http://static.howstuffworks.com/gif/...iger-info0.gif I also want to paint my engine orange and black,,, so scratch the cowl mod.

Im thinking of doing tiger paws on wheel paints,, maybe some teeth on the nose? For sure I think a graphic of a tiger on the tail would be cool...

Thoughts?

Got pics of your tiger choctawflier?

Sorry to hear about your heater problem, its hard to build with mittons on! My Tiger just has some white stripes over the orange (looks like whats on the box) cut out from Econkote. I wish I put more effort in it like Tiger graphics. I think if you you put a big tiger face on the front and a long tiger fur coat down the fueslage it would look pretty cool at the field

This was my first time working with monokote and I sure hated it (my heatgun could barely shrink it!) I'm used to Solarfilm but its not fuel proof.

I've been using http://www3.towerhobbies.com/cgi-bin...?&I=LXK325&P=0 to shape the edges of the control surfaces. I find it almost worthless. I'm wonder if a small router w/ table and a round over and a chamfer would be better. Thoughts???
