2231 Fin Alignment Guide Model Kit, Color Varies

I'd have given it a star or two more if one of the backets on the three fin arrangement wasn't loose. Causes these rockets to fly with bit of a wobble. The four fin arrangement works great, but I seem to be on a 3 fin kick.

Cheap and effective. I wish I had this when I was a kid. 90% of the time when I had a problem with model rockets as a kid it was because of fin alignment, and this goes a long way towards eliminating that problem with model rocket kits that need balsa wood fins attached to a cardboard tube. I have built several kits with my son and have had no problem with fin alignment. You still have to be careful, but this eliminates the guessing and trying to line up measurements on a curved surface so everything is straight and spaced evenly.

Viele Jahre habe ich die Flossen meiner Modellraketen mit Augenmaß und Flosse für Flosse angeklebt, was doch recht mühsam und Zeitaufwändig war. Jetzt geht es in einen rutscht. Ich habe das Teil auf ein Brett montiert was ein umkippen vermeidet. Die mitgelieferten Adapter passen gut bei normalen Flossen, ich habe mir noch eigene Adapter aus alten Motoren gebaut um noch flexibler zu sein, mittlerweile möchte ich das Teil nicht mehr missen.

Works as described

Son enjoys using it to build his rockets.
