Lil Squeaky

Whilst i was out yesterday I decided that today i would take the Wraith the same route up Roznik to do a fresh comparison of the two trucks

Here it is :

– the Wraith needs to slow down , right now its too fast and maybe i’ve been spoiled by the low end of the new 35t ,but i feel it needs a bit more low end grunt , ill try the smallest pinion i have first.

– the difference of the wide stance makes a big difference on climbing

– i still manage to make some flips over the rears, so a set of overdrive gear might be in order

– the steering circle in tight spaces is still tight.

– whilst i got up some of the obstacles the scx-10 has had issues , the wraith got hung up on some the scx-10 had no problems, especially on the narrow parts.

– the front tires need more weight,as the fronts seem to light .

– speaking of tires , they also need better foams

– i forgot how strong the Savox servo is .

– there is some squeaking going on when the links flex , might also be the cvds that need a shot of WD40, also on closer inspection the front upper links are bent a bit, that needs replacing too.

– a rebuild of the drive train is in order as the rear diff sometimes clicks.

– as on the scx-10 i need to finalize the wiring and move the esc to the back to make space for a servo winch.

– the hood needs some more magnets as it opened once on a particularly heavy rollover

– after an hour i believe the LVC kicked in, it must be the combo of the bigger tires, faster (25t) motor and the heavier weight.  I forgot to bring a spare 😀

– i was thinking that if i had to recommend a vehicle for someone to get into scaling it would still be the Wraith over a SCX10 , its a bit more forgiving and easier to transit from a faster vehicle.

Rewired

The other day i’ve installed a 35t motor into the SCX10 , its this one , it comes from the same factory as the King Bolt, Ansmann and RC4WD and it was a bit cheaper than the Tamiya CR35 (cheap enough shipped for no customs 🙂 ) . Before the installation it went trough a break in procedure of 5 min at 3v and 5min at 5v. The top speed is a bit lower than the stock 27t axial , but the low end control and the torque is visibly better, also it still has plenty of wheel speed to clear the tires .

since i had the truck electronics opened i did a bit of cable management . The LED and Servo Wires went into a spiral hose to protect them, also i somehow managed to break one of the white LEDs so i replaced the simple axial light controller with a GT Power one , this one makes the front and rear lights be at 50 % when not moving and they light up more when you give it some speed/brake. I have to fiddle around with it some more when install the light buckets to the body . Also i’ve shoe gooed the light bucket covers which my dad painted with his steady hand to keep them from falling of  as per usual.

The old bent steering link was always turning down and getting caught on everything, i made a new one and added the aluminium tube as to the lower links and bent it a bit to clear the pumpkin, also i’ve made a new drag link and moved it to the other side so its now longer and it should be better on the steering. With with the aluminium tubing the links looks so much better now. Notice on the upper picture that the wheels are a bit toe out , this should help with the turning circle a bit more as well.

Things i still need to do is make a servo wire extension so i can move  the Castle BEC next to the motor . Also i need to make some kind of a bracket for cable routing , and get a project box to put the light controller and the receiver into it as the axial one is a bit tight on space.  Oh and get better two sided tape .

This was a  summary of the work done since last time and now to todays trail report.

notice the nice new steering link

The 2 hour classic route on Roznik was a shakedown after all the new improvements : CVDS, 35t motor, new lower and steering links.

The ground was a bit softer than usual as it was raining for the last week, that allowed to test the wheel speed of the new 35t on loose ground. Im loving the new motors low end control and more torque.

more control

more control

The new made links slider much better , ill probably make some bent ones when i get a proper bender to see if that reduces the high centering , especially the rear could use a bit more clearance , if that does not help ill get a bit taller tire , but thats not really something i would like to do as it would take the truck into class 2 .

turns better

All the improvements to the turning circles are paying of , the lines i can take are tighter and turning around is easier , but im not there yet, some high steer knuckles and the accompanying aluminium c hubs are the final step.

taller tires maybe ?

a bit of flex

The second part of route i spend bouncing up and down ledges. I made a little ad hoc video about it . Enjoy!
