Build started basic questions - flybar cage and seperate BEC

[Bunter]

Hi all

Sorry for the newb type questions, I just started building my Mini-Titan :) and its my first heli build.

On the head assembly when fixing the flybar and the flybar cage, is it necessary to use the flybar grub screws to squeeze the flybar cage together to remove slop like in Finless's vid on the T-Rex 450 XL HDE step 4 video (right at the end). My cage doesn't seem to have slop like the T-Rex one and the measurements without squeezing are as per the manual. Just wanted to check with more experienced builders first.

I notice quite a few people using a seperate BEC with the stock Mini-Titan ESC. Is it really necessary and do you have to cut any wires on the stock ESC to disable its onboard BEC. Also can anyone explain how the wiring is done with a seperate BEC.

Any help greatfully received.

Cheers

Bill

Hi Bill,

If your flybar cage is a good fit with no slop then just tighten up the grub screws, you want to avoid pre-loading stress if possible.

I run a BEC because it removes the strain from the esc and lets it run cooler and also I don't trust the built in bec's. Theres many who use them without problems but I prefer a seperate bec.

Regards wiring it's easy. Firstly remove the red/positive wire from the esc's rx plug, then wire the 2 power leads of the bec straight to the + and - on the connector for the battery (where your esc neg & pos are soldered to). Then just plug the bec's rx plug into the battery socket on the rx, that's it.

Thanks Fixxer, that's what I reckoned on the flybar cage too.

Do most people use deans on these models? The reason I ask is if I'm thinking of getting a seperate BEC and Deans are the way forward for ESC - battery connections, then it would make sense to solder the BEC and ESC leads together when converting to the ESC to Deans.

Thanks again.

Deans are great but I prefer EC3 battery conectors. I use a small micro deans on my BEC so if I ever need to remove it from the heli it will be easy.

Deans are great, I use them on all my electrical connections as they can withstand large amp loads and extreme heat and it's impossible to join them up the wrong way, just make sure you get the soldering right to start with ;)
