Status: offline 		jaejw1 i was running the hpi mini star wheels an radial tires at that time. i made the mistake of making too many changes at one time. i run latemodel dirt oval indoors on a damp sticky track and made all these changes at one time- new syle body and added a side air dam, changed to brushless(mamba 6800 at that time) hpi mini star wheels and tires, added 3mm ofset total to the front and rear wheels all these changes made the car drive totally different. i really know better but i guess a brain fart happened. seeing how the car responds with the detta stock tires, i dont think i would have enough torque to pull out of the turns with the ae cars if i change to the m inferno wheels and cf tires. i would for sure need to drop a tooth on pinion.


below are after changing to ammo motor
at the end of my last race night in the main i made several changes and one was changing back to the stock buggy tires.
i practiced some after the races were over and 21/41 does seem to work well. im going racing on another track friday 13th i'll see how it does on a track that is more oval and less paper clip shaped.

i dont have a set up sheet but i run 50wt ae oil in all 4 shocks now, shocks in at bottom out at top and about 1/4 "of clips in rear shocks and about 3/16 clips in front. 80% steering travel L&R

Status: offline 		sparkedflyer i would recomend the aluminum knuckles if you buy the buggy and especially if you run open wheel bodys or off road. the truggy is sweet man it has long arms and pivot ball front knuckles cool lp tires and looks awsome. if i didnt have so much in my buggy i would build one. by the way a bone stock detta truggy with a 1200 6 cell pack put down 39 laps last week at the track where the bl guys best is 42 . ouch ouch

does anybody know if the detta truggy spedo will stand 7 cells?

Status: offline 		we run 4 min quals and 4 min mains. just over 6 sec per lap. i may have made the truggy sound a little better than for real. in that race there were only 3 vehicles. latley in our races there will be 7or 8 vehicles and traffic slows us down some.sometimes a lot. i dont run lipos so i cant say but i guess since it has a higher votlage it would be faster. if all goes well friday and i feel the need for more speed i may go to 3 cell lipo but must get educated first. dont know the terms and do's and dont's yet and will need a charger up grade too. oh and i forgot to mention the truggy has long shocks too and i like the body mounts. i am just a little worried about the plastic axle shafts being so long probably gona need upgraded right away since they are so long.

mAh is mAh whether it comes from NICD, NIMH, or LIPO. You can find higher mAh lipos that are the same dimension as NIMH and thus get more run time. The lipo shield will work and if you plan on running lipo with the stock ESC I would get one, unless you are timing your runs and know when to stop.


Typically people see longer run times from BL motors because they are more efficient.

Status: offline 		Hey, thanks for that good bit of info about the batteries. Now that i think about it, that makes sense. I still am not clear on what pinions and/or spurs to change or use if I change to something like the Ammo motor? I know its a thicker shaft than the stock VR3 so what pinion am i supposed to buy for it? Do I have to change out something else (spur?) or what?

You'll need to get some robinson racing pinions, 48P metric. They also make a 48P non-metric, but you need the 48P metric. The lower the number the more torque, but less top speed. So what size pinion is dependant upon what you want out of the vehicle. The spur is the larger gear and you can also change that to tweak your gear ratio for more torque or higher top speed. Spurs work opposite of pinions in that a lower number gives you more top end. It's kind of a PITA to change out a spur so I would just stick to changing pinions if you want to adjust your gear ratio.

for the detta ST.. i would gear it at 19/41 and if you need more top speed.. then 21 or 22/41,, just watch for motor heat

and probably 22/41 for the buggy with stock wheels..

im planing on buying a bunch of pinions to check which is best for the stock ST wheels.. so far i like the squirt of the 19/41 but top end is lacking (for my taste) but i may switch to a 21/41 and see wha that does to the motor .. the torque and the top end..

Status: offline 		How exactly do you change the gear ratio? Is that just a matter of changing pinions and/or spurs? I ordered a 16 tooth pinion along with the 13 tooth that comes stock. What kind of ratios can i get with those and how do i adjust that. Also does advancing the timing risk the motor burning out? How do iknow which way to turn to slow or speed it up? Thanks!!

Status: offline 		I just ordered a 41 tooth in addition to a 45 tooth and I have a 13 and 16 tooth pinion so I can play around with the ratios. How do i advance timing on the motor? Which way do I turn the can?

Status: offline 		sparkedflyer i guess i didnt understand the question. to do more than 39 laps in four minutes one doesnt really need more mah but more speed or better driving as long as the battery you are using is still providing most of its power at the end of 4 min. since the lipos are higher voltage i would guess the speed should be increased and the lap count would be higher. i think that makes sence doesnt it?
this may help with the timing on vr3.

Status: offline 		Thanks to all for the info. I also found some great resources on Castle's site, whcih talks about gearing and motor/battery combos. Great stuff. One more thing. I found the Permax, Ammo, and GH 4700 motors, but they're all $60 or higher. Has anyone seen them cheaper anywhere? Looked on e-bay and no one has them.

Status: offline 		they are that price because they are bigger and more powerful.. it is worth the money..
i say the gh4700 for the beginner bl user that wants to race their vendetta. and then once you graduate and want more.. then go for broke and get the permax..

the gh4700 is a great motor.. i ALMOST won a big race with the gh4700... had it not been for a bad battery ... something told me prior to the main.. dont run this battery,, i did and i pid for it..
