I am 400km away from my build
- so nothing happens in my man-cave.
Meanwhile - I have deliberated on some important choices and am about to nail down the following basics - unless I get negative primitive reactions and warnings from fellow modellists:
- brushed geared-down-motors (545 or 555, after I understand their main differences)
- analog rudder servo
- OpenTx (Taranis+, 8-channel FrSKY receiver)
- genuine tank steering/twisting, i.e. two ESCs
- power distribution board à la Action
- Kort propellers (these are _expensive_! Where should I buy two opposite direction 54mm 4-blade?)
- SLA main battery - any low current applications of future with separate batteries, if necessary
First stage without extra functionalities, i.e. no switches, sounds, telemetry, but those added once I can make the basic configuration sail. => expandability, removability and modifiability imperative.
Maybe less fundamental choices, but important nevertheless:
- a modular electronics tray, power distribution, receiver - the most needed connectors, charging connector etc) right under the the superstructure (see next)
- removable superstructure, so there is little reason to remove the whole deck
- provisions for lights, rotating radar antenna (connections between hull and superstructure, mast)
- if I can, removable bridge deck - for temporary attachment of a camera in its place.
- removable/replaceable sole plate so I can change _everything_ in the engine room, and be more relaxed in screwing motor, battery, servo mounts etc into it..
- install cross member aft for really good fasteners for the removable deck (au Terry @ Tugforum)
I feel confident about these, but feel free to bring me back to square 1. Now - with no purchases made - it's cheap to make mistakes
This I couldn't decide: Should I go 6V or 12V ?? I would say, 12V gives more degrees of freedom for the future. But under-voltage for the motors would keep them from running too fast. On the othe hand, I thought I'd use down-gears. - Difficult...
