Completely agree with that.
As a test i started with the Cyclone S but i decided to see how the cyclone S goes with getting hop ups to the full level using 3racing parts. Also there are some parts incompatabilities with the 3racing parts. Bulkheads seem to be too narrow and are basically now paper weights for me. and also motor mount was a slight bit narrow so you have to upgrade the centre pulley mount to use it (the 3racing spur gear holder is suitable though).
Overall the cost is marginally more (meaning it is not a bad option for people on a budget) but in my opinion the 3racing parts are by far inferior to the real hotbodies parts. I would stick with the TA-05 and aim to upgrade to a full racing level chassis (preferrably a Cyclone, although there is a lot of bias in that comment ;P) not the Cyclone S which is an entry level car.
