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

, also has anyone used these parts on there old Raptors and what was the benefit in flight performance.
