Default blade grip/esc question

I am a new owner of a gaui 200 v2, and I have a few questions I wanted to just through out their.

I know how to properly set the backlash but even when I just leave the heli plugged in (like when I was adding sub trim on set up) I noticed that the esc was getting warm. Is that normal?

Also. I have crashed it once, and I notice that I can pull the blade grips out horizontally and there is little clicking sound. It is only about 1mm as an estimate on each grip, and I have made sure that I have thread locked the screws all the way into the head. I that normal?

Thanks!

not sure about the second questions, but I have noticed the esc gets warm too when just having it plugged in so I'm assuming that is normal. I believe its just the bec dissapating heat.

Ok, so the esc is behaving normally. Thanks for the reply.

Can anyone else chime in about the slope in the blade grips? I hate to have it fling a blade at me, and I know for a fact that everything is as tight as possible (with out stripping) and with applied locktite.

take your grips off, and i'll bet you find some loctite in the spindle. clean it out, and reinstall.

Ok, I will go though it again when I have time. So I am guessing that this is not how the grips are suppose to be.

By the way, what is the best way to remove locktite from a deep screw hole? Is there some dissolvent which would do the job (nail polish remover, alcohol etc)?

i use rubbing alcohol and a toothpick to work it in a bit, then i run a dry screw in a bunch of times untill it comes out clean and you have no slop in the grips.

Glad that the question was asked, as I was just about to. I think that there may be loctite in there and worst comes to worst I can just change it out.

Thanks guys!

I use a 1.6 mm or 1/16 " drill bit , in a pin vice to dig out any build up of loctite, then use a M2 tap to clean out the threads, then wash the hole out with acetone before applying fresh loctite

I have the clicking in both of my grips on my new Gaui, no problems there that's how they're designed. In flight they will both be pulled out anyway.


Make sure to use blue loctite and not low strength for the grip screws, and yes over time loctite can build up in them.

Whats the best way to remove the pin that keeps the spindle in the head. That has proven to be a PITA so far.

Knock it out with a punch, it's not tapered, against a hard block with a hole in to accept the pin. I made a small punch from a hard masonry nail, ground down to just under the pin diameter. place the punch on the flush side of the pin , and give it a sharp tap with a hammer. The other method is to use a small pinion puller tool, but the punch works every time

Sound like a good idea. It will ease the frustration that I have had trying to get it out with the vice and a pin

Ok so I changed the spindle, however I still have slop in the grips. I have all the washers and no threadlock (for the sake of checking for slope) and the is still the little 1mm click on each grip. Should I just shorten the grip screws?

I don't understand what type of clicking this is? I've never seen something like this, you should have no play at all, are you sure you have both bearings in the blade grips and the washer that goes on the end?

Try pushing the grips inwards, then pull it outwards. You may hear a click...

I have "washer | bearing | bearing | screw head". There's some play in mine as well, but haven't noticed a problem in flight. It would be interesting to see what happens if you shorten the screws though.

Ah, you are talking about the bearings moving in the grips? You could always try and loctite the bearings in.

If you have used the correct screws, you should not need to shorten them.. is it just some lateral movement in the grips, or can you flex them both up or both down at the same time? It may just be the bearings moving in the grips, in which case it wont be a problem. If you have not used the correct screws, they should be 10mm thread length.
