retracts - remember Nov 10, 2010 ?

Hi guys,

in late 2010 (Nov.10 to be exact) i developed a retract system for the dynam DC-3 using original parts and 3d-printed moving parts.

i now found a possible way for you to get a reliable and extremely strong retract mechanism for your dynam DC-3.
i just added my youtube-video of the testing:

Dynam Skybus DC-3 Fahrwerkstest Retracts Test (3 min 36 sec)

and this is the original post (i changed my rcg-alias cause i now wanted to use my real name):

So this is the link to a company in the US printing models for everyone at fairly reasonable prices. It is still pricy but maybe someone could make moulds and replicate some parts.
this is the link to the parts:


The main carrier sits in the original dynam main support baseplate. Glued to a 3mm carbon rod, it can rotate/pivot through torsion of that rod. In the middle of the wing sits the retract servo.
all the other pieces are connected by 3mm carbon cylinders and secured with CA. for the support at the back a 5mm carbon cylinder is used.
this system is light, easy to assemble a extremely durable. i am now running my retracts for two years without a single problem. works like a charm even after this long time.

so then - if anyone is interested just go ahead
