I was thinking about buying an Arrma Limitless and putting in the same electronics that my Talion EXB has:
Spektrum 150a ESC
Firm 4074 2050 kV motor
Spektrum G2 6S 5000 mAh 100c battery
Spektrum Servo S652
Spektrum Receiver SR6110AT
Using the RC speed calculator online, https://scriptasylum.com/rc_speed/top_speed.html, and plugging in all the numbers from the stock setup on Arrma's Interactive Exploded View, I am calculating a top speed of 128mph (minus drag, gravity, wind, friction, weight, etc.) Based on the calculations that my Talion shows (72mph even though it only reaches 62mph with this setup), I am figuring about a 14% loss in speed for these variables. Using these formulas I am calculating a final speed of around 110mph.
My questions are as follows:
1) Is 100+mph a real speed to expect?
2) Can the vehicle withstand the abuse it will take at these high speeds? In other words, will the diffs, axles, etc. all hold up well?
3) Will the motor overheat using the factory pinion and spur gears of 27T / 34T respectively?
4) Has anybody tried this setup and if so, what information can you provide me with?
To be clear, my local hobby store recommends the Hobao on-road vehicles. However, when I use the same calculator and I plug in what the stock set up on the VTE is, I only come up with a top speed of 55 mph minus the different variables of weight, etc.
Please don't be bashful, I would like to know everybody's individual experiences with this setup and the temps of the motor/esc after a half-hour of use.
P.S. My Talion has never overheated once using the factory set up and I also upgraded the pinion on my Talion from a 15T to a 19T.
