Tercel in bulk - http://www3.towerhobbies.com/cgi-bi...1P?I=LXBVAJ&P=8 <--- not really worth it...

My recommended shop, Hobby Linc : http://www.hobbylinc.com/htm/est/est3222.htm <--- Just $10.99 here!

So.....even though I was initially a bit disappointed in the grade of balsa in the kit (heavy) I have to say I'm happy with it.




Every Tercel I have made with an airfoil sanded into the wing typically gets around 60 seconds in normal air. I've made all of them with this heavy wood. If your going to compete you could always use the kit contents to trace another set of parts made out of contest balsa.

Did you use the included Wire clip supports that came with the kit?

Also, the way the fuselage is built I've never had one break yet even if the model cart wheels on landing.

I am very pleased to hear you won a contest with this model.

John,

Glad you saw this. Thanks for a great design. Even though I'm a longtime airplane modeller, I haven't built a free flight HLG in decades, and of course the Tercel's glider clearly has HLG heritage. And this was my first attempt at a boost glider (never did one in my first rocketry period 30-odd years ago).

Yes, I used the clip support, as did the two other contestants who also flew Tercels in the meet. Very handy.

One of the others flew away in a thermal.....I think we lost sight of the glider at about three minutes. Since it was her first flight her overall score was lower as she didn't have a second one to substitute.

I got a second kit and noted that it had a similar grade of wood, so I figured that it was by intent. It certainly makes for a strong model.

That Tyvek-layer-in-the middle fuselage is very strong! I was kind of amused that the instructions call it "paper".

Wow, three Tercel's at one launch. I've not hooked any of those boomer thermals you saw that day with my Tercel's which isn't a bad thing, since they land far enough away in no lift conditions. Estes standard balsa wood specificaiton is on the heavy side which is great for fins but not so great for glider models.

If you still have yours, can you post of couple photos of it!

I still have mine....yes, I need to post a picture or two. It might not be tonight, though.

The dense wood is great as it allows a very defined and thin airfoil in the end. So much so, that while I was sanding, I would hold the wings up to the light and use the amount of light shinning through to help me gauge high spots in the airfoil.

Hey for $11 ... you really can't go wrong.

J

P.s. I think we can all agree the Tercel is LIGHT YEARS ahead of the Estes Eagle ... now what a piece of crap that design was!

I also have a pair of Mini-Dactyls I plan to try out this year. With any luck, at the end of the season I'll still have one of the three...
Thank you. Give this (see: http://www.apogeerockets.com/educat...wsletter231.pdf [page 6]) a try for anchoring Kevlar shock cords to motor mounts. I'll be curious to hear how the Q-EZ and Mini-Dactyls fly (if they glide okay in hand-toss trimming flights, those low aspect ratio gliders should work fine in powered flights). Your "Charlie Brown kite-like streak" with boost-gliders *has* to be broken at some point. Also:

The original, larger version of the Mini-Dactyl (I think it was called the Pterodactyl) used an 18 mm motor booster and was known to have good wind penetration characteristics. At my age, though, I appreciate the (usually) shorter walks that 13 mm mini motor powered boost-gliders provide. :-)

Thank you. Alas, Hobby Linc doesn't ship to Alaska, but eHobbies www.ehobbies.com (who offer the Tercel for $11.99) does. AC Supply www.acsupply.com also carries the Tercel, for $10.19.

Heartily seconded! (Regarding the pictures.) Also: John, I have an idea for something that you could put on the Estes web site that would increase interest in the Tercel kit and attract model airplane folks to try it. Since it is similar to AMA-type contest hand-launch gliders, if you put a downloadable set of AMA-derived hand-launch glider contest rules (see: http://www.hippocketaeronautics.com...rules_print.htm ) and a downloadable box score sheet on the Estes web site, builders of the Tercel kits could utilize these ready-to-use contest materials to hold their own boost-glider duration contests. The only rule that would need to be changed is the "no dropped parts" rule, which could be amended to exempt separable motor pods. In addition:

I'm just curious--what contest rules did your group use (NAR or AMA)?

We used the NAR rules. Which AMA rules are you referring to? Freeflight or RC? Those for Hand Launch Glider or Catapult glider?
