Hubsan X4 H107C design question

Post by W95 » Sun Aug 26, 2018 6:29 pm

Hi all:

I know the X4 H107C is not a FPV but unfortunately there is not a forum for this quad so maybe the administrator can create a new forum or someone might have some input.

I purchased another X4 H107 to replace one that was damaged beyond repair. We have noted three strange and curious design oversights:

1. Like the previous model, the wires to the JST connector that comes off the main board of the quad, gets severely compressed between the canopy and the battery during both insertion and removal of the 1S battery. The problem is particularly bad when trying to remove the battery as you can imagine this can put tension on the weak solder joints on the board and with the wires now compressed between the 1S battery and the canopy, the battery is quite hard to remove. I am baffled why there is not a simple cut-out for the wires coming off the board so the battery does not drag back and forth across the leads. Or, why is there no grommet in the canopy through which these wires could have been routed? I supposed one could cut out a small groove with a Dremmel tool but it seems strange something like this is not inherent to the quadcopter.
2. Equally odd is the fact that the OEM Hubsan 1S battery, once fully inserted into the quad, is nearly impossible to remove without pulling on the wires leading to the battery, which is probably not a great thing to do. We learned a tip from a YouTube video to put a small tab on the end of the battery with Duct tape or equivalent so the battery could be pulled out by pulling on the tab rather than on the battery wires. But, why isn't a tab on the original Hubsan battery or why wasn't it designed so you don't have to insert the battery in as far and could therefore grip the side of the exposed battery to pull it back out? Certainly one could simply not insert the battery in all the way, but then this would surely throw off the balance.
3. Once the battery is connected to the board on the quad, they hang out the back end of the quad. The manual says to twist them and tuck them up inside the canopy to ensure proper flight quality but honestly there is very little room or a cavity in the canopy to do this with. This also necessitates twisting the wires which probably puts strain on the board solder joints. We have tried to tuck them upside what little space there is in the canopy and after a few seconds, we note the wires have untwisted and are once again hanging out and below the quad.

Any thoughts from the board members or Hubsan?

Ailsa:
I see you have been commenting on a few recent threads. Do you have any advice on my questions?

Doesn't anyone from Hubsan have an answer here? I understand this is the FPV forum, but there really should be separate forums then for the non-FPV quadcopters, of which Hubsan makes plenty.
