Alvin, it doesnt take side by sides... ONLY stick packs
but there are several prototype chassis running around that might take a sidebyside pack.
none have gone into production...all you can do is hack the chassis and hopefully make em fit somehow.
Although that post before this one has a good idea... sort of...
shoulda mounted the ESC and receiver on opposite sides under the winglets that hold the normal stick packs.
and shoulda installed a custom hump pack instead of the stick pack.
I think that would be really nice...but already sold my TL01...
