I think you'll find the install to be quite easy.
One heads up. The screws that hold the B motor onto the mounting plate are barely long enough. At least they were with mine.
You may have to ditch the washers or use thinner ones.

You are absolutely right. I did not use the washers but I am wondering if you have a longer set of screws you suggest, so I can use the washers. I think the washers are needed for the extra heat protection of the plastic base.

Pault, I did the mod this morning and it is a straight forward one. It took me around two hours but keep in mind I am not mechanically or electronically inclined. See the attached pictures of my progress. I had the opportunity to compare the HK BL set I bought couple of months ago vs the stock. Now that I know I think I can do the HK as well with no problems. It will take a little more time since you need to manually prepare the connectors and mount the pinions, but that's it. I think you cannot beat the HK BL vs the X350 brushed motors replacement. What is left is to put the zip ties and taken her for a test. All systems perform properly as per instructions on my bench. Last but not least you must install the HP shaft, which is a prerequisite for the BL mod. In addition I would like to thank H&H for his assistance.

BL Test flight

I flew her for few mins and everything was working OK, until came down from hovering 3 feet above ground. Back to the bench and I found out motor B was moved and the pinion was not engaging with the gearI guess I have to find longer screws and use the washers and until then no more flying. What Extreme flyers are using the same screws with not only the washers but along the heat insulation plate under motor B. Daaahh Any clue where can I find longer motor mount screws?

I am wondering how did you manage and I cannot? Same screws with same washers. I admit you have warned me before attempting the mod.

Well, I found out that one tooth of the gear B is broken. Just ordered another main gear (B) which by the way is the second in the row I do not know is it me or the Heli?

H&H, can you post a pic on how you tucked all the wires et al. The way I did it the stock canopy does not fit and I had to use the eFlite 400 canopy which accommodates all. I am just curious.

Thanks for posting the pics. I don't understand why these ESCs are so big vs the motors which are so small. Anyway, as soon as I will get the gear I hope I will do a better job this time. BTW I have located the 2mm x 6 screws which are needed for the B motor proper mounting. I will pick them up tomorrow. What canopy is this?

I took both out and they are still sort. We need 2mmx6 to be long enough to hold the motor in place and not destroy the gear in a crash or hard landing by slipping out. My 0.02 cents

Pault, I am attaching a pic showing the kit mounting B motor screw with the washer vs what I use now for the proper and secure mounting of motor B. As you will see it does not take a rocket scientist to figure that out Just make sure you follow my suggestion since it cost me another B gear (motor B got off and chew the gear) plus the aggravation. Since there are four 2mm x 6 screws in the package I will replace the motor A screws as well just to be on the safe side. I used the brushed motors washers too. Good luck with the mod.
