Whats the story with my Goblin 420.
Posted: Wed Nov 29, 2017 6:25 pm
So as some of you know, I swapped my Goblin 570 for a Goblin 420.
My 570 is 4 years old but only has around 40 flights on it.
It was in mint condition, with Lynx upgrades.
This was the deal offered to me.
My 570, with two sets of packs. No FBL system ( as i would transfer my Ikon to the new 420)
For a 420, just been built for a magazine photo shoot (5 flights) with two packs.
Not a bad deal eh?
Well i said good bye to my 570 (sad day) looking forward to my new 420 arriving.
When i got it, everything look good in the pack. Then the trouble started.
I noticed a radius arm looked slightly twisted, so i checked the other. It was twisted too!!!!
So i decide this was enough for me to do a full rebuild to check everything.
This was bought from a reputable shop. I called to ask whats up, and was told that it fell of a table in the shop, but nothing was damaged.
So i wont bore you with the rest. I'll just list what I found wrong with this "NEW" heli.
1) Blade grip arms bent.
2) Thrust bearings crushed, and soaked in thread lock from applying too much to feather shaft.
3) Radius arms twited.
4) Servo tray brass insert stripped out.
5) Tail feather shaft bent.
6) Tail shaft damaged and bearings, due to wrong instillation of tail side plates.
7) All screws drenched in thread lock. numerous screws where already stripped out.Had to heat and cut screws out of feather shaft.
Frame screws had to be heated up and those that where stripped, luckily, I got them out with vice grips.
8) Tail blades cracked and fixed with super glue.
So, not so new.
If it had been a beginner buying this, I would have said send it back. But as I did a full strip down, I knew from experience that the damage was easily fixed with new parts.
So after explaining all the issues to the owner of the shop, he sent all new parts out to me.
He is adamant that this heli had only 5 flights and had fallen of the table at the shop.
Well thats either a fricking high table. or he is full of BS.
It was 100% from a crash, with the way the head was twisted.
Anyway, I finally got it all sorted, and it flew like a dream........
Until the Ikon died, luckily on the ground.
Or thats what I though. Spoke to Ikon support, and after a few emails back and forth, they said they would sell me a new one at trade price, as mine was out of warranty.
Cool. Just before i packed it up, I gave it one last try by doing a full reset, and what do you know, the bugger worked.
Turns out something it my setting had changed to stop the tail servo from i initialising.
Check on my other Ikon with the same config, same problem.
Not sure what happened, as one day it was flying fine, then the next, tail servo was dead.
Only thing I changed was a GOV setting, but this cause the tail servo to stop.
Well now it seems all is good in the world again. So let go flying...... Oh damn, its raining LOL
