Exclamation *Help* Mad Gear Racing Desert Wolf Baja Upgrades

I am new to this hobby and I just got my first RC car. I was reading a lot about it and the downside about the car I got i that the battery sucks and it lasts only like 15 min or so. My question is I want to add a brushless motor and a lipo battery. And I saw some kits that I think they might work. any input is greatly appreciated.

Specifications:
Scale: 1/10
Drive: Rear Wheel Drive
Battery:? 7.2V 1800mAh NI-MH battery
Motor: RC 540 brushed motor
ESC: 1/10 brushed ESC
Servo: 9kg Standard Servo
Radio: 2CH 2.4Ghz radio system
Charger: USA Charger
Wheelbase: 290mm (11.4")
Ground Glearance: 20mm (.79")
Size: L: 400mm * 260mm * 125mm (15.7 x 10.2 x 4.9in)

ESC and motor Combo

Lipo Battery

P.S. just ad www before the links to see the electronics.

"Only" 15 minutes? From an 1800mAh battery? First, 15 minutes is not at all bad, considering runtime. Second, getting this much runtime out of such a small battery, indicates that the motor and therefore the whole car are not exactly powerful or fast right now. Changing that to a brushless 4-pole 3000kv combo... let's say the difference would be quite... remarkable. However, 4-pole motors are usually used in 4WD Short Course Trucks only, since 2WD (and buggy at that!) cannot really handle all that torque very well. IMO, you'd be far better off, going for a sensored 540 sized motor, probably 17.5T and a sensored ESC for this kind of car. The Gens Ace lipo is ok, if it physically fits the car.

Thanks for the help. I am thinking on this little motor

what is the purpose of the sensor and do I really need it?

Sensorless brushless systems (especially the smaller 1/10 scale, a little less on 1/8) will show an effect called "cogging" on accelerating from zero and on lower RPMs. IMO, on a 2WD buggy you'll want smooth power delivery without cogging (as 2WD is by nature a little harder to drive on acceleratation than a 4WD).

That motor seems ok (although I have never heard of that particular model, but it is the type of motor I was talking about).

Not sure that ESC is sensored - it doesn't look like it...

I see. I really appreciate your help. I will look into an ECS with a sensor then.

you can get a variety of chargers, is there something specific you are wanting the charger to have for features (AC/DC, certain amp rate, lipo capable, etc)

Default Charger/Battery

I would like a lipo battery but I do not know what to get. I do not have a hobby shop close enough to me to go there and ask and I am very new to this. I lost my charger for the battery it comes with but it had broken after using it twice. If I could get a charger for the original battery that would be great, but I would also like a lipo and charger too so I can buy it later.

EDIT: I would just like a safe charger I can use to charge the battery in an hour or two.

This charger will probably give you all the features you need and more:

TowerHobbies.com | Hitec X2 AC Plus 2 Port AC/DC Multi-Charger

charge a lot faster too than what you are seeing now I am thinking.

Using tower hobbies discounts (sign up for membership if you plan to order more stuff from them as discount codes are even better, like getting 15% off) you can get some savings. If you can wait till E-cash comes around again you can get some extra money to spend too.

As for lipos if thats your thing, give SMC a look. I would probably do any of there cheap 5000mah or so battery packs. Just make sure your ESC can handle lipos with proper voltage cut off.

Most good lipo chargers will have a mode in them to store lipos properly. Taking care of lipos really isn't too hard, pretty much make sure you don't go past cutoff (ESC handles this), charge using balance charge setting (regardless of what some yahoo tells you, balance charge your lipos as you gain no benefit to NOT doing this), and storage charge your lipos when you're done with them.

Thank you so much, I haven't gotten to drive this for over a year!

One more thing, does this charger work with the battery it comes with or do I need an adapter?

You would need an adapter or to change the plugs on the battery and the ESC. I would prefer switching them to something more standard like Dean's plug or EC3 plugs
