ZMR X-210 battery strap cuts
#1
Hello guys! 
So glad you're here. I have kind of question/suggestion. Have been using ZMR-X210 about 4 months so far and love it. The one thing that really bothers me are the battery strap cuts on a top plate. IMO, the one which is closer to the end, is too far. For example, when trying to go fast, I remove action camera and try to push the battery a little bit forward to keep the center of a gravity in a middle. However, the second strap is just not close enough to hold the battery Sad 
Adding some photos for better understanding:





P.S This happens with my 1300mah pack

what I do is I go underneath the top plate and not use the slots for the strap.

Good idea. At the same time I wish they will be able to just update the next batch.. Just got a new QAV-R without problems like that Smile

Thank you Bob, I've forwarded this to our engineers to see if there's any we can do to make it a better frame.

Just a quick question, I was thinking of puchasing one of frame's ARF package, if your engineers find a solution to the problem and manage to fix it, how long will it take to the better frame in the combo?

Thanks

Hi Tashu.Cristy, actually it is the first time we receive the report for battery strap cuts. After an internal discussion, our engineers believe that the current design of strap cuts is reasonable and do not need to make further change. If you are using a small battery as shown in above picture, simply use the 3M Adhesive Velcro to stick on both upper plate and the battery, and with one battery strap, the battery will be secured.

Another example how it's done on QAV-R

the reason why the QAV-R is able to have the battery strap cut outs located like that is because the frame only uses 6 stand offs and the ZMR uses 8. because of the location of the stand offs the cut outs have to be spaced further apart. if the cut outs were closer together it would weaken the top plate significantly. maybe what they can do is remove the larger square cut out and move the battery strap slots that are in the front further back? I think this would strengthen the top plate and make strapping the battery easier.

Why have two sets of straps slots in the first place?  Get rid of the rectangular hole in the middle and get rid of the forward slots all together  and move the rear slots forward about and inch....problem solved?

I also normally would use two battery straps, especially for anything bigger than a 1300mah. 1800mah 4s was ripping trough almost any single strap with exception of some MRP ones that I additionally reinforced but they are also very heavy. I prefer to have two standard rubberized ones on each side of the lipo so it doesn't force them too much during a hard crash.
Find me on Youtube and Instagram. I currently fly: NOX5, NOX5RAirblade Assault 130 and drive a scrap RC car

IMO, reducing the length of cuts and placing them forward will resolve it without weakening whole construction.

Another super minor suggestion (since the weight of the frame is my biggest concern) would be to have a separate aluminum hardware set Smile

I'm looking to buy a 210 frame, and if it weren't for this issue, this frame would be on my short list.......shame. Undecided

Don't let that stop you Chris, I have 2 of them and have yet to have a lipo eject itself on a crash due to the position of the lipo straps.
They really are a great quad for the price.

the battery strap is only a minor issue. like Biggles said its a great quad. I still have the one I won and it's been through the ringer.
