I have run some un-scientific checks on the maximum speeds of my HL tanks.

mergen

WOW!

Pah co chu puk

A+ for math.

Some highschool teachers from the early 1970's (if they are still with us) would be shocked

I was surprised by the stock HL Panther and Stug speeds coming out close to the historical values; I always thought the stock HL's were too fast, at lease these varients don't seem to be.

The 3:1's have been great additon to my Tiger I., I think the stock HL Tiger might be too fast but I am not putting the stock gear boxes back in to test it

As I recall, the Panther, Tiger, Panzer III/IV all ran within a couple of mph of each other...right around 25 mph.  But, that was top speed on the road and generally wasn't sustained because of the wear and tear on the tanks.  Your Tiger's speed is more correct for the upper end of the sustained road speeds in a road march.

Glen B

Yeah, that's true.My test was to determine top speed, like road speed, as with the originals, I don't generally run mine full speed on grass so with a reasonably close top road (basement floor) speed and reduced speed outdoors, I think the stock Stug and Panther/Jagdpanthers are pretty close, which surprised me.My Tiger with the stock running gear but with 3:1's surprised me with just how well it drove and handled outdoors.

My Feedback: (1)

I failed math, but I think my KV is at about 10mph at max setting.

Joe,
Pull out the sledge hammer and shift into second!

or just take the real speed of a tank divide that by 16 and you'll get the top scale speed of the model which represents the real tanks top speed

I've seen two different specs for the real tiger's speed one of them being 23mph

So at 23 mph divided by 16 gives you: 1.4375.  This would be the top speed of your 1/16th tiger in scale speed.

This tank speed chart might be helpful as well: http://www.rcacn.org/ It is found under "Rules for Engagement" Along with tank speed listings & times.

If your tank is too fast you can always try a smaller pinion gear as opposed to a new gear box. It is cheaper alternative and easier most of the time. Slight modifications may be required to move the motor closer to the first gear. Here is a hint: Use a strip of paper inserted between these two gears to set the proper clearance.
Good luck, Bob

Interesting hint...do you smash the paper between the two gears where they mesh?

thecommander

Take a strip of quality paper (like from a shredder), Do not use newspaper or cheap thin magazine paper. Insert it between the pinion gear and the first gear and feed it in a 1/4 turn of the first gear. Tighten the set screws and remove the paper strip. Bench test the TU & motors and then break them in. It works well for me. Bob

Off road speeds are usually more a result of the local AO than true 'what it will do in the mud' speeds. Remember, tanks, especially buttoned up for combat, are essentially blind. The driver can often not see that nasty 3 m deep gulch until he is on it. If the commander also doesn't see it, then someone's ride is going to the body and fender shop asap if the tanque is bucketing across the veldt at a more than prudent speed. Good recon was also a must when possible without getting your tail feathers shot off.

Glen B

Yeah, sure, post that AFTER I do the math

That's a good resource and it agrees with my figures when I correct them for the 25 ft test run, because I used 20 feet

I printed the chart for future reference, I'll just have to clear another 5 feet of "test track".

Thanks for posting that.

my tiger 1 run right at about 25 kph scale. i just put it on the treadmill and used that speed reading and figured scale speed from that.

Pah co chu puk

Did you get any video of the tank on the treadmill?

Shabbernigdo

nah no video. dident think it was somthing any one would really wanna watch : )
also its how i adjust the esc to make the tank run in a straight line.

Agree whole heartedly, The M-41 pioneered the new larger persicopes, so the driver didn't have that 1 x 6 inch prism stuck nearly on his nose. But in spite of all, cross country was a slow process and totally guesswork over some terrain. This was complicated more by "new" IR periscopes which made it impossible for judging distance in any way. Many teeth were lost and nose injuries were caused by speeding over a field.

Speed was generally far below max, particularly on German tanks. They were notoriously weak and prone to breaking. Not all spares were there for added armor...they were needed. American design tracks are the best.

Glen B

Update, for general interest.

A new HL Tiger I with the original metal (not 3:1's) ran the 20 foot distance in 9 seconds, indicating a scale 24 MPH.

This is going to be the new "project", it will be gettting 3:1's to address the speed and improove driveability, and have an SLU installed.

candycab

Did this when I got my Panzer III with Nylon gears and it came out to 23MPH

I was surprised to say the least.

Haven't done my Pershing yet, it has Max400 Motors in it & factory metal boxes.

I couldn't believe how much the DBC slowed it down. It doesn't really matter much, it was just more than I thought it would be.

I used this guys calculator since Mathematics and myself are like oil & water.

I'm one of those calculator dependent people
