Well, here we go with some modifications for the quad...Ive been looking it over quite thoroughly and deciding what all i plan to do to the quad..This thread will be more of an "as i go along" type thing so i will be constantly updating and sharing my findings that i find beneficial to the quad in one manner or another. One particular mod i've seen before set off a light bulb in my head and it can be a beneficial mod but i wasnt impressed with how it was executed.... if im going to attempt this mod i want to do it properly and maybe offer it up to other U807 owners as well who might be interested in it. ...Im not going to really mention much of this mod as of yet until im able to design, build and test it for myself...I promise once ive tested and the results are confirmed ,i will reveal what this mod is and its benefits...This will be the "Star" mod for any Nihui u807. The Nihui was offered in 2 versions..Version one already came stock with bearings and offered a 150m range...The version 2 being sold now comes with bushings and its reported the range isnt as far but i cant say by how much less as i havent seen any reported numbers..just reports. There are some popular mods we can do and if you have a version 2 , one of the these mods is replacing the bushings with 3x6x2mm bearings to make it like the version 1 in that respect...Not really a cheap mod unless you care to wait almost a month or longer to obtain them from china..I chose to get the bearings quickly and, this was at a cost of almost $10 for the needed 8 bearings...Ill share more thoughts about the bearing mod a little later. One popular mod is using higher C rated battery with a mah capacity of 750 to 800mah for increased flight times and a more powerful punch...For me personally i dont care for much added flight time as this really burns up motors quickly from excess heat but, a higher C rating can add some wanted punch to the quad...I plan to try the Venom 700mah 35c battery...It does come with a micro losi plug but i will be replacing it with the proper JST plug. Another popular mod is using the WL Toys V636 motors which are reported to offer even more power and speed especially with a higher C rated battery. My mod coming soon.
