How can I get longer run times on micro t

[novarider]

I have a stock micro t and It's fast enough for what I use it for but I want longer run times. What is the best way to get longer run times

[Full Montee]

I do not know of any other batteries that are NiMH that will give you longer run times and keep the Micro-T the same speed.
However if you are all right with it going faster :( and getting longer run times :D try the LOSB0862 - LiPo Charger & Battery: Micro-T

[novarider]

How much longer will the runtime be? Just trying to decide if it's worth $50

[notfastenuff]

bearings, bearings, bearings, the lippo is great but the bearings increase runtime! probobly better get the threaded axles too. that way its easier to get the carpet fuzz out of your bearings!

[novarider]

Beatings really make that much of a difference?

[notfastenuff]

If your not interested in adding speed.....yes. the bearings do add alittle speed as the wheels free up. but this is what makes the runtime longer as well. so to answer your question yes bearings make a difference in runtime. as does making sure the gear mesh is correct and the diff is free. The smallest pinion in the kit will aslo increase runtime at the cost of a little speed.

a lipo is not needed, imo their a waste of money at this scale of rc, their more over kill than anything, ecspecially still running stock electronics since you will have problems with shut down. bearings should be the very first upgrade along with threaded axels. hair, fuz, dust, etc gets stuck around the axels, it will cause the wheels to spin slower and less free. with bearings the wheels will spin alot more free. if your running the stock gearbox, loosin the 3 screws a very tad which will free up the gears in the gearbox alittle and cause them to spin better, your gear mesh you dont want to tight, use the paper method to align it properly. if you have a few bucks to spend, grab a 3racing or thetoyz gearbox which is equipped with bearings. also a higher mah nimah battery pack will mean longer run time's. with what i have said above with just bearings, threaded axels, gear mesh prop set and gearbox loosened some, i could get 15-20 min run times.

also, if your motor gets hot where it feels '"too" hot when touching it, your having a binding problem. normally caused by an over tight gearbox (they come to tight out the box) or the gear mesh is not set properly. Junk around the axels will also cause the motor to get hot and so will a dirty motor. Just something to think about if you have had longer run time's than your currently getting now. ;)

[novarider]

It's brand new but the 5 or so minute run time is really short. I will get some bearings but who makes a higher mah battery and where can I get one at?

[TyHodge07]

oh, in that case, check your gear mesh and loosen the gearbox. when you loosen the motor from the motor place, pull it away from the spur gear. loosen the gearbox until you can spin the back wheels freely. yes its normal for the wheels to spin opposite when spinning just one wheel, lol than reset the gear mesh.

here is a video by horizon/losi one a larger scale, but it is the same concept:

Right now if I spin one wheel the other spins the same way not the opposite and it doesn't spin freely it kindof clicks like the motor is spinning. I have an e-revo and it feels like when I turn that motor over. Your saying the rear wheels should spin freely like the front wheels?

[TyHodge07]

just place urself looking from the drivers side and turn one wheel to the right, than looking at the other wheel, which u would be looking at the inside of the other wheel, it should spin to your left. but really its going to the right like the other, but 1 wheel should go backwards and the other spin forward. when the motor spins the spur gear than spins the rest of the gears in the gearbox the diff catches which causes the wheels to spin the same direction. if you loosin the diff (which at this scale there isnt a screw on the diff itself, but the gearbox screws tightening and loosing it on the outside) it will cause the wheels to spin more free and the opposite direction when spinning just 1 wheel. when you drive it, you should be able to let off the throttle and the car still roll a few feet, if it doesnt than its to tight.

loosin the 2 motor screws or pull the pinion off the motor. loosin the 3 screws on the gearbox, their in a triangle shape location, turn about a 4th turn.. turn one wheel see if other spins the other way.. if not hold one wheel and turn the other, just keep doing that and switching from each side (talking about the rear only). do this until it loosens it up and gets the gears to set better inside the gearbox. you want to get it to where you spin one wheel to the right, than the other spins to the right also, but lookin from the side it appears its going the opposite way.. i think im explaining it right.

[novarider]

I understand. It should act like a differential. How easy should it be to spin? I have been into rc for about 10 years just nothing this small so I don't know how it should feel

[TyHodge07]

yea, i added some more to the post above your last. these little things do have a diff also. but on mine ive gotten them pretty easy to spin, they all have seemed alittle ruff at first, but once set right, and the gearbox loosened just enough etc than over some time of playing with it, it should start to spin more freely. like i said earlier, the gearboxes out of the box come way to tight, ive had to loosin one gearbox almost 2 full turns on each screw to get it to spin more freely. just over time, the gearbox will break itself in and spin better.. i have found adding a inbetween thick/thin grease to the gearbox, not to much but just enough to coat the gears has caused the gears to last longer and spin more smooth.

[novarider]

Mine is deffinatly to tight then. If I'm going full speed and let off the throttle it stops in probably a foot it doesn't roll much at all and I thought that was odd now I know how to fix it thanks a lot. What about a higher mah battery who makes one and where can I get one?

[TyHodge07]

ill search on the battery pack for you.. i think they were at www.cheapbatterypacks.com

[TyHodge07]

if i remember correctly i seen a 180mah on ebay. having the stock T chassis without he extra battery room limits you to only a couple other battery packs.

[novarider]

I could always zip tie a battery on top. I will have to look on ebay

[novarider]

Could two battery packs be wired in parallel to double the run time?

[TyHodge07]

it could, but me personally wouldnt only because it would be like double the weight. once you get the binding and such solved and start getting 15+ minutes of run time's you will be more happy.

[novarider]

I loosened the tranny case and adjusted the gear mesh and the wheels spin opposite now and spin pretty easily. The run time increased a little bit which is better. Will a battery for a micro dt fit the micro t? The toyz has a 300mah battery for the micro dt and I'm wondering if that will fit the micro t

[TyHodge07]

no, its a larger battery pack, the dt's battery compartment is larger because of the extra length. remember wheel bearings will increase your runtimes also.
