As a fun RC boat enjoyer with a few years of bodging and bashing behind me I'd like to use up some spare components on a silly build and need some advice. Last year I modified a Tear Into cheapo jet boat replacing motor, ESC and battery with a brushless setup. Very popular, easy and fun too.
I'd like to use an old cheapo 'Stealth' twin-propped hull commonly found on ebay/amazon for £40-£50 (super-lightweight with quite a nice hull) and adapt it to take a single 2858 brushless motor with a surface prop using a flexi shaft. I know nothing about this type of propulsion but understand why a flexi shaft is required.
Are there any previous posts about the matter I can read before wasting other people's time?
What do I need? An output unit (?stinger) and a rudder but how do I connect the components? Graupner seem to do a flexi coupling. Could I then connect to the ?stinger using a standard propshaft (stainless shaft and brass stuffing tube) or should the whole drive length be cable/flexi?
How do I optimise the ?stinger unit position during the final build assuming the set up is intended to be of the surface-prop variety. I assume again that this is largely down to setting the boat in a bath to measure displacement etc?
I was filming my friends lads twin-propped toy boat from my MFA Piranha the other day and although unimpressed by the boats powerplant(s), twin 380 motors, I couldn't believe how light the boat was. As a cheap toy the thing represented great value for money and outlasted my Piranha after I hit a submerged something-or-other flat out and mutilated my rudder.
I have so many unused components I'd love to throw them into a cheap boat but simply can't get my head around the flexi/cable propshaft thing.
Cheers in anticipation of advice or a link or two for half-wits like myself!
