In Step 20 a standoff was cut for the dowel connection.
The directions were followed, the standoff was cut to 1/8" tall X 1/2" long.
The inset picture shows the standoff is too short, it won't fit slide into the lug cradle.
The short standoff was removed and a new one cut, this time almost 1/4" tall. This will allow me to sand to the correct height.
After some sanding the fit is better and the cradle holds the glider well.
I've never been a fan of the shroud line "Gripper" reinforcements. They are too thick and don't easily fit in a small diameter body tube.
Here's an older Quest parachute pulled from another model.with the Gripper tabs.
You can see how they crease when packed.
I won't be using the kit supplied parachute. It's "crispy".
... those darned "gripper" tabs. First time I saw one was with the Quest HL-20, on the end of the streamer. Getting the streamer into the holder tube was rather fiddly especially with the stiff Gripper tab. Curling the Gripper tab usually meant that over time the streamer would peel away from the Gripper tab.
ReplyDeleteHi Naoto,
DeleteI think the gripper tabs were meant for hanging products on wall hooks. They aren't good for rockets.
Now that you mention it... yes, they do indeed look like those stick-on tabs you put on packages (that don't already have a hook area) to put items on merchandise hooks...
DeleteSelf-adhesive reinforcing rings for hole-punched paper might've worked a bit better.
With regards to the positioning of the glider hook -- those measurements are probably based on the molded-in lugs in the fin can. To replicate the positioning of the lugs, you'd probably have to glue the replacement lug on a standoff (not only were the molded-in lugs thicker, but if I'm not mistaken, the molded-in lugs weren't flush against the surface).
ReplyDeleteNaoto,
DeleteYou might be right -
The instructions have you cut off one fin and lug (post), then glue on a white Mylar lug back on the fin can for the glider attachment. The standoff height was off.
Maybe if the lug post were hollow and just the fin were cut off, that standoff height might be correct.
