ENGLISH TRANSLATION:

Judgement:
A very well processed boom, sold directly via mail order and shops. (you don't need to have a diploma in engineering to make use of the two enclosed hexagonal-keys and to stick the spars (reduced diameters) into the front end.
In other words, the boom can be dis-and reassembled, quite comfortable for frequent travellers ! Additionally the spars come with a scale for your harness line set and are coated with soft grip material for tight and comfortable grip.

Adjustment:
Properly processed length adjustment every 25 mm.

Result:
Excellent stiffness for such a lightweight aluminium model at a "lightweight" price – Very sympathetic / likeable !!
