Just want to show you people wat I've been up to for the past few days. This is my e-savage with a custom extended low cg chassis. The Chassis plates have been extended by 40mm. Each stock chassis plate was cut in half and then rejoined to L-bars using 8 screws. The L-bars help
extended the plates.
The stock transmission gear box has its direction reversed and moved forward to just behind the receiver box. The now front center universal shaft is shorted and the rear universal shaft replaced with a stock axle shaft. A custom motor plate is fabricated. The motor plate allows the use of 17T to 26T pinions. The motor is lowered by more than 50mm and is slightly offset to the right so that the motor can doesn't touch the rear center universal shaft. A powerful (but noisy) 12V mini fan is positioned right above the center of the motor. So the position of the fan roughly tells u where motor is below. This chassis mod allows the use of 36mm diameter motor with a length of up to 90mm (assuming that there is such a motor) but the esc will have to be shifted somewhere else. Without shifting the esc, the maximum length of a 36mm diameter motor that can be used is 80mm.
The mamba max is positioned at the rear end. It is attached to a fabricated plastic piece that has been glued to the stock X support piece. A mini blower is right in front of it (beside the motor). Although the motor/esc area is cramped but air flow is pretty good thanks to the powerful duct fan and the mini blower. A blower can produce higher air pressure compared to a similar sized duct fan and so imo, it is better at pushing air through the gaps in between the fins of a heatsink. Which explains why a mini blower is used to cool the esc.
The white boxes at the side of the chassis are the battery trays with venting holes on the inner side. They are made of 1mm thick PVC sheets. Each weighs at around 40g which is pretty heavy considering they are just battery trays. These battery trays put the lipos slightly forward so that the CG of the e-savage is balanced right at the center. The lipo batteries are held in with Cut up L-bars which are secured with body clips.
I have plans for a gear cover but I simply need a break from modding the e-savage. Will probably do it up next week. A lot of planning was done before the mod was started. I've tried to reuse as many stock parts as possible so that I dun have to fabricate or buy new parts. There is no hop up at all other than the 1/2 inch offset wheels. The e-savage currently weighs at 4.2Kg.
I haven't got the chance to test run it yet but I will probably do it soon. I really hope that it can corner better now. The original E-savage is simply
too top heavy. I am thinking of modding the shock towers next. Is there any shorter shock towers and shocks that can be used on the e-savage? Can anyone give me a hint? Thanks.
Setup:
CC Mamba max
Feigao 540 7L 3511KV brushless motor
17T pinion and stock spur gear
2 x 4S Loong max 2250mah lipo 25C (Connected in parallel. Battery don't even get warm on the e-savage. Stays totally cool)
1/2 inch offset wheels
DX3.0 and SR3000 receiver
I've attached a photo of my Mini-LST with huge wheels for amusement. Have fun looking at my pictures.
