Ignoring the time gap, what exact is your complaint? Tech work quality? Tech work advice?
It seems there are four elements to your complaint:
Tech workmanship related:

- Wiring with "metric ton" of superglue
- Nuprol motor "too strong"
Advice related

Can you provide pictures of the Gate Aster or anything that says it is "non-airsoft"?
Can you provide pictures of the amount of superglue in your gearbox or where you think is the problem?
Can you provide model name of this Nuprol motor and also your spring, gear ratio, and battery used?
Can you describe what was the process of you agreeing to the work?
