tires tend to ‘balloon’ in diameter, which can cuase them to tear or fly apart, or at the very least

cause loss of control. One solution is to use tire foams, and another is to belt the inside of the

tire with thick duct tape (turn the tire inside out and run a couple of strips of tape around the

tire, being careful not to overlap the edges which would cause imbalance). Traxxas themselves

have introduced a 17mm hex and rims with the Revo Platinum, and this offers users yet another

upgrade route. The BL E-Revo comes with 17mm traxxas hex adapters and matching rims- these

are the same 'toothed' hexes as used on the BL E-maxx, taping the insides of the tires to reduce

ballooning and high-speed blowouts is advised.

11. EVX, EVX2 & MMM Speed controller

E-revo

Again, despite traxxas’s boasting the blue EVX2 is water proof, it is ill advised to test this too far,

as traxxas will charge for repair of any moisture damaged escs. It suffers in general to a lack of

voltage handling ability as freshly charged 6 and 7 cell packs can sometimes trip some form of

over-voltage protection, though this isn’t the case with all EVX2s which is somewhat baffling. It is

also recommended that you do not use the on/off switch at the end of a run, but to instead

simply unplug the batteries from the esc. Any warranty issues should be dealt with by contacting

the Traxxas customer service department.

BL E-Revo

The BL E-Revo comes complete with the brilliant CastleCreations MambaMonster ( MMM )

brushless esc and motor system. The esc is rated for 6s lipo or 18 nimh cells, the motor is the

NeuCastle 1515 1y 2200kv model, based on the popular Neu of the same specification. The BL E-

Revo comes with factory gearing of 18/65 which is good for about 35mph with 14 nimh cells or

4s lipo. With the optional 18/54 gearing 40mph is easily possible, but only with good quality

lipos; nimhs will not provide sufficient current ( amps ) for the esc & motor, and esc damage may

occur. This is due to something known as 'ripple current', whereby the voltage from the batteries

fluctuates rapidly and drops as the current output increases beyond what it can provide due to

high Internal Resistance ( IR ). Lithium batteries have much lower IR levels and so do not

overheat or droop their voltage output under such strain ( provided they are of a suitable

specification ). With 6s lipo & the correct gearing ( 24/54 ) it is possible to achieve a maximum

speed of around 65-70mph, though aerodynamics & tyre choice become critical issues at this

speed; strictly for on-road use only. It is very important when choosing lipos to select items with

a good specification & that will provide sufficient current for the MMM to operate properly. The

esc requires lipos capable of producing at least 120amps continuously, though the more overhead

you have, the longer the batteries will live for and the longer your runtime will be ( as an indirect

effect the voltage will not drop below the Low Voltage Cutoff ( LVC ) until nearer to the end of the

discharge ). To determine how much current your lipos will produce, simply multiply the C rating

by the mah capacity & devide by 1000, for example: 20c x 5000mah / 1000 = 100amps, or 40c

x 5000mah / 1000 = 200amps. For best results the lipos should be of identical specifications &

age/ discharges, though it is perfectly fine to use two different voltage/ cell counts in series, such

as a 3s & 2s lipo to achieve 5s lipo ( I like 5s lipo as it is the perfect mix of power and speed

when geared for about 40mph ). The MMM esc has numerous programming options & settings

that are accessible via the 'CastleLink' programmer. This unit plugs into the rx lead from the esc

& connects to a PC to allow changes to be made to various settings such as punch & torque

control, LVC settings, timing and start power, brake strength and also throttle curves etc etc; the

3908 does not come with this unit so it is an optional extra costing approximately $25; well

worth purchasing. Please see new Castlelink page on my website for indepth info on how to use

this device and the best settings.

12. Nimh batteries

E-Revo & Conversions

The best way to get good performance from any E-revo is to use good batteries, as these

ultimately determine your runtime and the amount of ‘punch’ & top speed your truck will have.

When choosing packs, consider the amount of capacity they have in mah (Milli-amp Hours), the

cell count/voltage, and the discharge rating if available. Higher mah will mean longer runtime,

higher voltage will mean greater top speed, and a higher discharge rate will mean more punch

along with more consistent top speed and acceleration. There are a great many brands out there,
