Default RC Tank F.A.Q.

Q: How long should I charge my battery pack with the supplied wall charger?

A: Add 15% to the battery pack's rated capacity, then divide the sum by the charger's output amperage to get charge time. For example, if you have a 2000mAh battery pack and a 400mAh charger, then the charge time is (2000 + 0.15*2000)/400 = 5.75 hours or 5 hours 45 minutes. If your charger's output is 500mAh, then the charge time is 4.6 hours or 4 hours 36 minutes. However, you can charge the battery pack for 5 hours initially.

Q: How do I remove a track connecting pin?

A: Push the pin out from one end with a small push pin. Note that most connecting pins have serrated end and can only be pushed out one way.

Q: How do I remove the road wheels from an HL Tiger I?

A: Insert a wide flat blade screwdriver between the suspension arm and the back of the road wheel. Then twist the screwdriver to pry out the road wheel. Once the wheel axle is loose, hold the suspension arm with the fingers on one hand while pulling the wheel straight out with the other hand. It is important not to exert any pulling force on the suspension arm because it might break. You can also use a small pair of bent nose pliers to pry the wheel out from the back.

Not all battery packs will fit Heng Long battery compartment. The stock battery pack is around 5 1/8" or 130mm long, so when looking for a replacement, look for one that has a similar length.

Q: How do I remove the rear idler wheels from a Heng Long Tiger or Panther tank?

A: Use a sharp, flat blade screwdriver or a paint scraper to split the idler wheel, then pry out the wheel axle. If you don't plan to keep the plastic idler wheels, such as when upgrading to metal ones, then you can use an electric hot knife to melt the glue holding the two halves together. You can also use a saw to cut through the glue.

Heng Long Tiger/Panther smoke & sound board wiring. Apparently, it's OK not to connect the wire from the power switch to the receiver board, shown in the middle picture below, as reported by some people.

Q: Is it possible to convert the left stick on a Spektrum 2.4Ghz transmitter to self centering for RC tank use?

A: Yes, it is possible to replace the rachet on the left stick of the Spektrum transmitter with a return spring. Print and fill out Horizon Service & Repair Center Checklist found here:

Q: Should I get a Smoke and Sound Heng Long tank or is the regular one just as good?

A: The Smoke and Sound ( called S&S on the forum ) tanks come with more than just Smoke and Sound, it has different electronics that allows approx. 10 proportional speeds as opposed to 2 speeds in the non-smoke type and It also has better range, In short, pay the extra $10 for the S&S.

Those road wheels are pretty tough to split apart. They are not just butt glued together. One half of each road wheel is inserted into the other half, which resulted in more surface area for the glue to grab. I'm still looking for a way to split the road wheel without damaging it.

M26 Pershing not controlling problems..... possible fix

Hi If you find your M26 not controlling properly I found out that where they screw the antenna wire on the holder inside the body it was actually going through the tape they had over it and hitting shorting out to the motor can causing all the problems...take it apart and put electrical or duct tape over it then give it a try.
This worked for me

Richard,

I thought, after reading lots here, the wire from the switch to the receiver board is usually not re-attached. Please correct me if I am wrong.

Yes, some folks do not re-attach the wire from the switch to the receiver board. I usually re-attach mine just for completeness.

Default RE: RC Tank F.A.Q.

hello,

Does anyone have ANY idea how to ADD the wheels to a HL Panther? I am upgrading to metal everything and got her all stripped down, but it seems I have to bang the wheel pin in and I am afraid of busting the plastic shaft the metal idler arm connects to...

Any ideas?

Q: How do I prevent the track connecting pins from sliding out?

A: Here is a quick and easy way. For plastic tracks, get a can of spray primer designed for both plastic and metal. For metal tracks, get a can of spray automotive or self etching primer for metal. I use Krylon red brown primer for plastic tracks and Krylon Rust Tough red oxide enamel primer for metal tracks. Apply a coat of primer, followed by a coat of color of your choice. The primer will adhere to the exposed side of each metal connecting pin, preventing it from working its way out. Note that paint by itself does not stick well to the smooth metal connecting pins.

Default RE: RC Tank F.A.Q.

Q: How do I break in the metal gears in my Heng Long tank?

A: There are two ways to break in the metal gears. I will go over the quick and lazy way first:

1) Charge the battery pack and put fresh batteries into the transmitter.
2) Remove the tracks from the tank to lessen the load on the motors. I would also remove the drive sprockets.
3) Put the tank on a level surface.
4) Turn on both the tank and the transmitter.
5) If you have the smoke & sound transmitter, slide the throttle trim up. If you have the 2-speed transmitter, use a rubber band to hold the throttle stick up.
6) Let the tank run at low speed for an hour. Then shut it down and let things cool for 10 minutes.
7) Turn both the tank and the transmitter back on and run the motors in reverse at low speed for an hour. Then turn off the tank and let things cool for 10 minutes.
8) Turn both the tank and the transmitter back on and run the motors forward at low speed for an hour.
9) This concludes the lazy break in process.

Note that this is not the best way to break in the metal gears. The factory applied grease in the gears will prevent them from being fully broken in in this relatively short amount of time.

Default RE: RC Tank F.A.Q.

Q: What is the best way to break in the metal gears in my Heng Long tank?

A: Here is the method I use:

1) Remove the gearboxes from the tank. It's not necessary to desolder the motors from the board.
2) Spray strong commercial cleaner/degreaser onto the gears.
3) Use a brush to clean off grease and cleaner.
4) Rinse and dry.
5) Obtain a can of medium grit lapping and grinding compound. If you can't find one, then use a good non-gel, tartar control toothpaste. However, the toothpaste will take longer and won't do as good of a job as the grinding compound.
6) Apply the grinding compound or toothpaste to all gear teeth.
7) Screw a 3mm allen bolt into the drive shaft for the drill chuck to grab onto.
8) Insert the allen bolt/drive shaft into an electric drill and run the drill at low to medium speed. Be sure to wear eye and mouth protection.
9) Grinding compound and metal shavings will spray everywhere, so be prepared. After an hour or so, use a degreaser to clean the gears. Then rinse and dry. Give the drive shaft a quick spin with your fingers. The gears should continue to spin freely and smoothly for at least two seconds. If not, repeat from step #6 above.
10) Repack the gear teeth with grease suitable for gears, such as molybdenum, and reinstall the gearboxes back into the tank.
