And we are back with yet another wave of changes and upgrades. In use the truck as it was had a ton of power whenever you needed it, but it was far too much for me. The truck had also become very heavy and less of what i wanted it to be. I want it to behave as a fast cruising type of truck, i dont need huge air or massive wheelies or stunts or anything, just something to enjoy in the local parks on sunny afternoons. With this is mind i grabbed a few other parts and made a few changes. Youll have to excuse the badly formatted photos, its all via mobile.
This is how the truck currently sits. Those tvps are custom cut with files i modified from a member of the hpi savage central facebook group. They are 4mm, light and strong. I also had him cut me a set of hingepin braces in 4mm, and a battery tray too which was entirely my design. I also designed a new servo mount which tucks the servo right in behind the front shock tower and braces the servo saver; pretty proud of that one . The truck will be converted to 4s only, using single batteries with the same mgm controller but a traxxas 540xl motor this time. It has a much higher kv, so should still shift reasonably with the lightened truck. Unfortunately i didnt get a chance to weigh the truck before i tore it apart but from carrying it around i can tell it is signifcantly lighter than it was already. These tvps flip the alza centre diff 180 to use a front motor configuation and leave room for a battery between the frame rails which means i will have to make/buy different centre driveshafts. This is probably the most abitious ive been with the truck, its stayed like this for months now and i really need to finish it off.
The reefs servo will without a doubt be powerful enough for this truck, the linkage has almost zero resistance as it is fully ballraced. There is also enough room for the motor cooler traxxas have for this can, which i believe i will likely need.
I went to a set of dace engineering hex adaptors instead of the IRC ones because i dont like the fitment method of those. These are a much stronger setup.
My 4s gens ace packs fit well in that space. I need to machine some battery standoff posts. The tray has provision for adjustment forward, backward, left and right with slotted holes underneath. There is plenty of room for battery cooling too.
I also switched out my IRC shocks for the traxxas maxx shocks you see here. They are smoother and handle the lighter truck better. They also weigh about a third of the IRC shocks because of the difference in oil volume.
I weighed the tvps against the 5mm alza ones i was using, the carbon weighs half as much. I am going to fabricate a 7075 aluminium skidplate for the underneath of the truck because im worried about stones causing the carbon to delaminate. I probably need to epoxy the cut edges to help with that too.
And this is a better look at the battery tray. Those two straps and my standoffs will hold the battery firmly. Im excited to finish this truck, i also have a brand new ford f150 bodyshell ready to paint up for it when the weather isnt so bad. There is much to do, a few things to 3d print and fabricate but its getting there. I probably need to stop modifying this truck and drive it more. Id say it is my favourite rc.
