heads_up

And that did the trick, completely forgot about that as an option, this is a new type of Servo i've never used before so makes sense it has a different range of motion. Thank you!

Hi all, I have a stock TT-01E that I have just recently changed the servo on, while I didn't pay too much attention to the last servo it appears now the steering arm that connects from the servo saver to the steering linkage is binding as its being pushed forward by the servo and at full turn puts pressure on the servo saver (I can see it expanding). I have tried mounting the servo both ways (it is >8mm from top to mounting point on the servo) and neither seem to help. Do the shoulder screws that attach this arm to the servo saver need to be mounted completely flush or can I leave 1-2mm of room in them to accommodate the arm not being parallel? I would normally just swap to a turnbuckle arm and ball joints at this stage however the class I run this car in prevents me from using such parts. Any help would be appreciated, thanks.

Thanks for all the great replies, all the info I was looking for. Thought it was best to let you know how I got on - It was a really hard decision but when I ended up with an opportunity to get an extremely good deal on a TT-02B Neo Scorcher with Alloy Propshaft/ends, ball bearings and a few other hop-ups, well below any expected price it sort of swayed me towards the practically of it. This buggy will allow me to share some common parts with my TT-02D but also just get it up and running while I do some more research into how gearing/motor rpm's/t's/kv's work (any advise on this would be awesome). My end goal for this shell would be somewhere between 80-100kph if possible, but that's all its aimed at being, a fast fun dirt/carpark basher. I did also find that my local clubs run a 8.5t 4WD class, which if that motor/gearing would suit my goal would be cool to enter a few times to see how I like the club racing then look towards a more serious car, such as the DB01RR/RRR, we'll see.

Thanks for the further replies. I have looked into the DB01RR, definitely a model I would consider if I did want to start doing track events and such but being that I am just getting into this hobby I think my best options are to stick with something base end for now or like you said hold off for a second hand unit and then carry out maintenance/repairs. It seems maybe I was too quick to rule out the TT-02B, I was pondering over the MS kit however it appears I am able to build it via hop-ups and a Neo Scorcher kit (which I prefer the shell of) for about the same price. It also comes with the brushed motor to begin with, a cost I'll repeat vs the MS kit but it does mean I can just get into it first then worry about motor/driveline upgrades.

Thanks for your reply TurnipJF, very interesting reading. It sounds like no matter the choice some modification is required in one area or another when it comes to a buggy with my requirements, I guess it comes down to picking the one with the smallest downfall. The DF-01 rear gearbox housing puts me off a little, being a re-release again as well I would assume parts/hop-ups will be limited between runs and if the DF-03 has similar issues with those idler gears well that's out too. The DF-02 never caught my eye as I figured it being between the 01-03 would be the odd one out, a simple propshaft upgrade seems like little downfall to overcome; I do recall reading about a potential downfall with the chassis being weak near the front (especially in regards to jumping/heavy hits) and also issues with square li-po fitment without modification. Which I also follow up with - by having a longitude mounted engine are the jumping characteristics off unless a well balanced motor/battery combo is used? Then if we are speaking of longitude mounted motors again we come back to the TT-02B, which AFAIK is the newest of all the chassis, whether this carries improved design elements I am not sure of but one would assume so. The TT-02B MS kit (for metal dogbones) combined with the DF-02 diff gears and a alloy engine mount seems like a very practical basher apart from the low ground clearance (reported by most people discussing buggies, how much of a difference this makes between models is guesswork to me). I guess if we factor in another criteria - say which could potentially carry with it club-spec features to be competitive should I ever want to move to this level? I know there are often class restrictions in terms of motors and gearing which makes my whole 'basher to be fast as possible' idea out the window, but if I am buying and hopping up a unit out of the box, may as well make it as versatile as possible. Thoughts?

Hi all, After discovering the fun that could be had in RC over the past 2 weeks as I built and started bashing my TT-02D I have already started the process of ordering some hop-ups and have a thirst for more! As places I can run the TT-02D is limited I am in the market for a 4WD buggy, however I am a bit stumped with choices. It seems one of the most logical choices is the TT-02B as it will share parts with my existing car, however being that I would like to go brushless in this unit (after seeing my friends D4 today with a brushless unit and how it wrecks tires) and the driveline upgrades required in the TT-02B to handle any real power, and by real power I mean I want to go silly and just have a ridiculously fast in a straightline buggy to hopefully not smash to bits. One unit that sparked by curiosity was the re-release of the DF-01 Manta Ray coming up this year (April from what I can find on the internet) and how that could handle a bit more power, yes it might cost more but I don't mind spending more money for a quality unit that I am going to have less issues with (as realistically possible for an RC car). TLDR Option: Want a buggy for bashing/jumping/straight line speed Asphalt, grass, dirt, etc surfaces Shaft driven (unless a belt driven is going to be better suited) Will have a fast brushless for being stupid Any help is appreciated, I have read through some of these threads and it appears you lot are extremely knowledgeable so let me have it
