Thank you sir very useful video, You might want to add a warning on this video to hold down the board very sturdy while pouring the hot glue in, I almost lost the unit doing this.. my board came up as I was pouring and I got glue everywhere .. lucky I was able to undo and fix the mess.
i just completed the mod using hotglue. first may i suggest practicing on a scrap circuit board, i tended to get a little too much glue everywhere. my hot glue gun is older style where i push the glue stick in with my thumb. then i tried the fix like on your second video, filling the entire body with glue. i had to figure out how to hold the circiut board down with one hand while squirting glue in with the other. i finally got it. looks pretty good. get it installed and see how it works.
@7digitalSunday Excellent, I think filling them with hot glue really improves. them... also remember to use 2 layers of foam when mounting. that helps also.
You mention during the fix that the "boards are reasonably vertical". How important is this? I had to fix two solder joints on one board due to solder overflow joining two connections already and before I apply glue I would like to know if I just need to go ahead and resolder all the joints just to straighten the vertical boards or not. If it is not that important that they are vertical, I'll let it go.
@koahawg1 Most of the 401s I have opened are never perfectly vertical.. the worse was about 10 degrees from the vertical.. I never noticed any difference in the performance. If yours is less than 10 degress from vertical it should be fine. Hope that helps
Man! Thanks a lot for this advice!!! My heli hk-450 with gyro hk-401b was allways "dancing" a little. i mean NOT a gain problem... It was jumping with a tail to the right and also to the left one time on every 3-5 sec, i checked also smooth drive of the blades. I fixed it like your gyro and not it's no tail "dance" :) Thank you!!!
@PhillyNarniareader I guess any glue would help.. Hot glue is nice and hard.. check out my more recent video.. i do the mod differently now and it works even better.
@b4566bb Ha ha.. the glue is not a problem.. she gets upset at the red locktite stains and the HOLES from dropped solder that burns through... lucky she is a good helicopter wife..

is it possible to do this with another glue (e.g. EPP glue, witch drys not too hard)?
Thanks for your great demonstration!
