You are correct, we have made videos of each of the new developments of the product. We chose videos on purpose to use as instructional tools to convey more information than paper, as well as actually showing the items in a functioning state. Your comments may be helpful for another user who is likewise trying to blend multiple vendor items on one build. Placing your comment on this item such as "Attention: Battery mount will not work with Dinky RC Cantilever Suspension" as you stated would then have to be followed up by saying "Attention: this body mount set will not fit Proline Lexan" and then "Attention: this battery tray will not fit 4s 5ooomah packs" etc.. even though we've never recommended them in the instructions, or on paper. Some things in multi vendor builds must be inferred by the builder. We chose to demonstrate the items and setup that actually do work together to help you make best choices when purchasing and building from our items.
