I worked on my Goblin 570 after going flying yesterday. One step forward two steps back. I went to test fit the battery on the slide in tray so I could see how much room there was behind it for a receiver battery and much to my surprise the 6S 5300's I was planning on running won't fit. They are too tall.
. The manual says a 60mm tall battery is the biggest you can use. Mine measure 60mm, but even without any Velcro or a strap they wont fit. The beating to my wallet continues!
To ad insult to injury I also discovered that the servo arms I ordered are the wrong length. I had measured the ones that are on it and they're 15mm from the servo screw to the ball link. I looked at the manual and saw 15mm. Well, it turns out what I saw was just for the tail servo, the cyclic uses 16-18mm arms.
More money, more waiting.
