Foam Leading Edge Repair

I decided to repair the dinged up leading edge on my Habu and share the process.  At my flying club we do electric group jet fly’s  About 10 of us were in the air one nice July evening, one of the newer pilots lost control for a second and went over our heads.  We all ducked and fortunately he regained control and didn’t hit anyone or anything and saved the model.  In the mean time, I looked back up and unfortunately, flew the wrong jet.  I quickly realized it was not my Habu and looked around the sky (Bad feeling)  in time to see the Habu heading straight down.  I chopped the throttle and pulled full up surprisingly, it recovered to a straight up heading but found the edge of the tree line and branches.  The plane was in good shape but had (as my friend Barney Say’s) “Kazooties” on the leading edges of the wing. A the time I wanted to try the Habu2 which featured a brighter color scheme.  So I retired the Habu to the basement rafters. Jump ahead a few years, my friend Tim needed a jet so I decided to touch up the old Habu.  Tim is the Chief Flight instructor at my PMAC club.  He does a lot to help new pilots.  I felt my old jet would be a good gift for him.

The material I used for the repair were :

15 minute epoxy, Foam safe Glue and kicker, Micro Balloons (TOPR1090) , Ezcote (DLMB37), Clear packing tape, Tissue paper, scrap 1″ pink foam, Hobbico “Hobbylite” White filler (HCAR3400)

Tools: Perma grit SB280 sanding block, #2 X-acto knife with #226 Whittling Blade,150 sand paper, 320 sand paper, throw away brush, Bondo Squeegee, Latex or foam safe paint.

Depending how bad the damage to your model is you can choose from the following methods.  The three I use are:

#1 Light damage: Hobbico Hobbylite filler sand to shape.

#2 Deep ding but not wide: New Pink foam sand to shape.

#3 Wider damage with scuffs and dings: Micro balloons and filler.

#1 Light damage.  Sand the area with 150 paper.  Apply the filler, a little “Spritz” of water first helps this water based filler to flow out and spread easier.  Let dry thoroughly, like a few hours.  Then sand with 150, don’t sand really hard just get the shape right then switch to the 320 paper to finish.

#2 Deep ding but not wide.  For this type of damage I like to replace the “divot” with 1″ pink foam and then carve and sand to shape using very little filler.  I cut out the damaged area in a square fashion then I cut a pink foam piece to the same size and shape, test fit then glue into place. You can use epoxy or foam safe glue.  When dry; carve (#226 blade) to shape and then using the fine side of the of the SB280 block block sand to shape then use 150 and 320 sand paper.  You may not need any filler but if you do fill the edges and finish off like we did in step #1.

#3 Wider damage with scuffs and dings: Micro balloons are used here.  Sand the area first with 150.  I put clear shipping tape along the bottom of the leading edge of the wing sticking out about 1/2″ past.  This works like a “Dike” to stop any  overflow of epoxy/micro balloon mix.  Mix the 15 minute epoxy and the add micro balloons.  I like to add the balloons till the mixture is near “Peanut Butter” thickness.  Now Squeegee the mixture into the dings and dent.  Put as much as you can without over filling the damage.  Let dry for about 20 minutes and then peel away the tape.  The glue balloon mix should still be a little soft but not sticky.  If it is real sticky wait longer.  With a new sharp Xacto blade trim any extra filler on the leading edge. It is easy to trim to shape now versus when the glue mix is fully hardened.  Let the wing dry for a few hours till hard and sand-able.  Note: Epoxy will dry faster if you find a warm 75+ degree area to dry.  When dry use the SB-280 to touch up the leading edge area.  Now use a good coat of the Hobbico “Hobbylite” White filler, fill the entire leading edge are using the squeegee to level it off.  Apply a good coat of filler to the bottom..  When dry block sand (SP-280) coarse at first flipping to the fine to finish her up.  Sometimes you need to repeat the filling step to remove any low spots.  When the leading edge is nice and smooth add a 2″ wide strip of tissue with the EZ Kote finishing resin.  1″ on top rolled around to the bottom.  This adds strength to the leading edge and averages out the repair areas slightly.  When dry sand lightly with 320 paper and apply another cote.  When dry paint the area with Latex paint, I used a Gray Behr house Latex paint.  Timmy was surprised to receive a (Almost) new jet.  We had fun flying together.

That night and we managed about 8 different jets in the air together. Zoom!

Estes Blurzz Dragster

We received the new Estes Blurz dragster in-stock.  Pretty neat.  I watched a You Tube video of the car in action.  Looks fun for a father/Son/daughter project.  Easy to set up track (A 90′ line and parachute trip wire)  The car runs on pavement and is reasonably fast but not scarey fast.  I think kids will love it but they would need adult help setting things up.  $29.99 each in stock at Flightline Hobby.  You will need the motors A10PT, 9 Volt and some recovery wadding.  All in stock at Flightline Hobby.  Estes says:

Blade Chroma

We received the new Blade Chroma.  Beautiful machine!  I think horizon felt the QX350 Name had enough numbers behind it so time to move on.  The Chroma reminds me of the next generation of QX350, but better.  A little bigger and loaded with features.  30 minute flight times.  I plan on carrying the BNF BLH8680 version for my Spectrum friends, no camera.  And then the CGO2 equipped version BLH8665 with gimbal, Blade 2.4 Transmitter ready to go.  Both machines and spare battery are in stock.  IMG_1339 IMG_1327 IMG_1328

Joe had his Hanger 9 P-47 that I built a year or so back, Tim Had his Hanger9 Bf-109 they did some flying together. Nice sounds.  Joe was also working on his Italian fighter running the new engine.  The Saito FA-100Ti is unique with its inline layout.  I flew my Mega Bat (Upcoming kit) Habu and my Artizan.  So for me it was a foamy night.  Started very windy (25 gusts) but settled right down at dusk.

Flying 6-3 to 6-15 Training and a Scale Meet

The last couple of weeks have been wet but between showers we managed to get in some flying.  Thursday evening was training night.  I helped one gentlemen “Brian” that flew F-4 Phantoms earlier in life.  Brian’s grand daughter “Macy” was their too and did a bit of trainer cord flying on the clubs trainer.  Brian’s goal is to fly a model F-4 in the future. I did 9 training flights that evening, good nights work.

On the 13th we had a PMAC Warbird flying event.  I took my Fokker Dr I.  Joe Fialka did a great job.  We had steaks for the first 40 pilots and SPAM for some of the awards.  That’s one way (Food) to get modellers to show up!  There were even barrage balloons in the parking lot keeping an enemy fighter sweep at bay.  Always something new at Joe’s events.  The weather cooperated and we did a lot of flying.  I think we had 8 World War I birds in the air at one point performing a “Dusk” patrol. Curt Spicer was there as well.  Always good to see Curt, he is a good builder and fun to talk to. John Valencia came out with his family.  They would all cheer when he would land. Fun stuff.   Other local clubs RCCD, Skymasters, Holly Club and a few I forget were there.  Always nice when outside flyers attend.
