Tighten Prop

[jjohn581]

Finally got around to installing a receiver and testing my mini eco and noticed that prop was spinning back when I let go of the throttle. I had just hand tightened to test every thing. Besides putting some locktite on it, is there any other tips to tighten it down? There does not appear to be enough threads to put a nut behind it.

Sounds like maybe your drive dog is too far out? Do you have a pic of this?

There is no drive dog on the ECO's. It is a 4mm threaded shaft and prop threads on. You must use loctite on them!!
