Can I ask if you posted the makes and details of all the electronics you used during the build? I wizzed through it again but didn't see any details except briefly in the first post? I got that you went brushless (with the blue spur gear) but not which motor/ESC/battery and steering servo you used, any chance of listing what you used?
That's very simple. Let's go. I'll add the details as well for the Javelin and Turbo Scorpion, but the approach is similar.
Turbo Optima
ESC : SkyRC Toro TS120A no fan, mounted under the the top deck.
Motor : Performa Racing (sensored) stock 10.5T
Sensor cable : 200 mm
Servo : Low profile SPT4412LV (12kg, 0.09s/60°) : it's low budget, works well and is direct fit within the chassis size - a non low profile servo may be too large to fit within the chassis size.
Receiver : flysky FS-BS6 placed under the driver. I don't really use the gyro included, though I've tried in a gymnasium track and it works well.
Mounted with OTW-1126 blue spur gear and 25T pinion to fit with the motor recommended gearing, but I can probably add a few teeth to the motor pinion as per my temp checks during runs.
Javelin
ESC : Performa Racing P1 no fan, mounted under the the top deck. (This ESC is the same as the Kyosho Le Mans brushless ESC, with a different color, and cheaper. Plus the programmation card exist for it)
Motor : Performa Racing (sensored) stock 13.5T
Sensor cable : 200 mm
Servo : Low profile SPT4412LV (12kg, 0.09s/60°) - same as Turbo Optima
Receiver : flysky FS-A3 placed under the driver. It's easier to place the driver, as it is lower profile than the FS-BS6
Mounted with OTW-1126 blue spur gear and 28T pinion to fit with the motor recommended gearing, but I can probably add a few teeth to the motor pinion as per my temp checks during runs.
Turbo Scorpion
ESC : Performa Racing P1 no fan
Motor : Performa Racing (sensored) stock 13.5T
Sensor cable : 230 mm
Servo : Low profile SPT4412LV (12kg, 0.09s/60°) - same as Turbo Optima. On this car, a low profile servo may not be required, but you need to pay attention two things : it's a 2WD so speed is important, and a servo with a bulky head won't fit under the body shell.
Receiver : flysky FS-BS6. I had in mind the gyro with the idea it could be useful, but actually I don't use it most of the time...
Standard gearing
In terms of Lipo battery, I have some vintage cars and some Tamiya cars and they are more constraining in terms of battery size. I use Lipos in stick format 134 x 46 x 23,5 mm in 4000mAH/45C or 50C. I works perfectly, and provides a quite decent running time with a discharge rate largely enough for those motors. The Kyosho legendary series are largely easier than the Tamiya in terms of lipo pack choice, and I may consider some shorty pack in HV and higher capacity eventually. I've not made any decision yet, as I don't need to change any of my Lipos yet.
Hope this helps.
