My Posts This: Topic Forum | Hi Chris,
Buy a Titan SE head and fit on stock Titan or buy the kit is what I'd look at personally. Depends on parts availability, how much you are comfortable spending and if you want the extra kit stuff for spares.
The SE roll belcranks and freewheel inner race are best to have and in line to the head block, dampers, mixers, flybar carrier, rear boom support mount,and mast. You can drill out the old white TR drive pulley bolt hole to 3.5mm. This is the initial package for upgrading parts I'd look at.
Hopefully you have the new angular TR feathering bearings and SS TR hub, or add them to the list of parts.
The rest of the SE stuff is certainly nice, more durable and blingful but not so important to flight quality.
$250 for a non TT aftermarket head is pretty steep. Fitting an aftermarket head misses the mark on other important structural stuff and at best won't fly any better than the SE head, plus it likely weighs more. If you add flight performance with an aggressive head the rest of helicopter is naturally under more stress.
I've taken the liberty to briefly list some key points and why.
Basic model modifications over the original Titan, to the best of my knowledge.
New mast New head block New mixers New dampers New blade grips New red paddles New rear boom support bracket Carbon fin New flybar carrier Metal washout hub New roll belcranks New pinion New clutch bell New start shaft bearing with block New metal idler pulleys on tail drive (Qt 3) New rear metal driven pulley New freewheel inner race with bigger bolt New white belt drive gear SS tail hub with new style angular contact bearings New canopy and mounting system. Selective use of button head screws Metal tail rotor pitch plate.
Note-the new clutch bell will not fit the old pinion as it has a dowel feature at the end of the threads.
Past airframe bitches by modelers:
Not enough pop= 30 degrees travel and with a control speed up design Slow cyclic=new mixers and paddles Pitching in ff= mixers/delta and flybar carrier Pinion bearing eating pinion= pinion retention nut with extra bearing Drive bolts shearing=upgraded freewheel and mast Tail boom wearing at boom support fitting= new fitting Tail hub failures= SS hub with angular contact bearings Failed idler pulleys=metal units Rear pulley wear=new metal pulley Head too soft and weak attachment=new head block and damping system Woof=delta reversal Canopy clip not secure enough=new canopy and mounting system
Past likes by modelers: Mechanical interaction free system-no economy electronic ccpm layout Simple reliable drive train, which has been copied exactly by what some like to call newer technology Wide parts support and parts compatibility with older versions Ease of setup
