Stadium Trucks are a category I love despite not currently owning one. My favourite, and one that has sat on my shelf in the past, is the HPI E-Firestorm, and for 2014 they have given it a bit of a makeover.
The Firestorm started out as the Firestorm 10T RTR, a 2wd, Nitro Stadium truck designed by Erik Shauver at HPI. If you look at the 10T here http://www.hpiracing.com/en/kit/10511 you will see many parts the same as the later E-Firestom, but with an alloy chassis and mid mounted gearbox. One does wonder if these parts could be adapted to make an electric, mid engined stadium truck, I never thought about that before today!
At the same time, the E-firestorm 10T RTR was released in Blue and Red (I had the Blue one) http://www.hpiracing.com/en/kit/10551 with 27mhz radio, 15t Brushed motor and basic SC15 speed controller fitted to a composite chassis, and well most of the other parts from it’s nitro brother.
Later came the E-Firestorm Flux http://www.hpiracing.com/en/kit/10554 with chrome wheels, a new paint scheme, and importantly a 5700kv brushless motor and Moviv SEC (both of which were rebadged Castle items, not a bad thing). The ESC could cope with 2s lipo, and had the appropriate Low Voltage Cutoff. The only downside, still a 27 mhz radio.
Next came the waterproof versions in Brushed (http://www.hpiracing.com/en/kit/105845) and Brushless (http://www.hpiracing.com/en/kit/105879) versions featuring a waterproof receiver box and ESC, another new colour scheme and finally a 2.4 ghz radio! Interestingly the Flux brushless version changed to a 4800 kv motor as it was reported that the 5700 got to some pretty stellar temeratures, and having a Mamba max and 5700 in my original E-Firestorm I can vouch that was the case. Gearing never changed particularly I believe because to date only one spur gear was available for the E-firestorm. The flux now could take a 3s lipo as well, and may have been part of the reason for the lower KV motor.
Enough reminiscing, what about the latest version for 2014? Well a new paint scheme featuring more black with orange highlights that HPI seems to be favoring this year. The big change is a new EMH-3s speed controller and MMH-4000 motor that is again a step down to 4000kv. Another new addition is an included speed pack featuring a wheely bar, a 3s lipo battery strap (taller) and a 77-tooth spur gear and 35-tooth pinion for insane top speeds. Also a new 2.4 ghz radio is included in what is a good looking package, it makes me want to buy one again!
