Alrighty!

well, my Savage Flux, that was bought as a roller, is running a cheap 2800kv motor, and cheap 150amp ESC, two 5000mah, 25c, 4s lipos in parallel, has done 68.4km/hr off road!

it had more in it, but with tyre ballooning I was struggling to keep the front end down.

I have no doubts it would do 90+km/hr on road, and at least 75km/hr off road. :)

the poor truck weighs in at a fairly fat 6.5kgs :p

Pipedup is a member here, he got 52.9 mph out of his Modified Picco .28

someone posted this about a year ago and i save it
hope it helps give you a better idea of how fast you are going

Typical Savage Speed Examples
This table shows some typical Savage gearing setups and the speeds you could potentially achieve, assuming a couple things. First, we're using a 6" tall tire. The original Savage tires were about 6-5/16" tall, but Dirt Bonz are more like 5-5/8" tall, so we're using 6" as an average height. Also, we're using stock diffs and 30,000rpm as the max engine speed. Some engines will go higher, but no-load speeds are much higher than what an engine can spin while pushing a heavy truck down the road. Use these numbers for comparison purposes and for theory, not as a guarantee of a certain speed. If you swap to CEN ring and pinion gears with no other changes, your speed will increase by 14.5%. So find your gearing combo and transmission type to get your 30,000rpm speed, and if you have CEN diffs, multiply that speed by 1.145.
Note Spur Bell Ratio 2-Speed Top Speed* 3-Speed Top Speed* HS 3-Speed Top Speed**
- 52 12 4.33 24.3 MPH 24.4 MPH 27.9 MPH
- 52 13 4.00 26.3 MPH 26.4 MPH 30.2 MPH
- 52 14 3.71 28.4 MPH 28.4 MPH 32.5 MPH

- 52 16 3.25 32.4 MPH 32.5 MPH 37.2 MPH
A 52 17 3.06 34.4 MPH 34.5 MPH 39.5 MPH
A 52 18 2.89 36.5 MPH 36.6 MPH 41.8 MPH
A 52 19 2.74 38.5 MPH 38.6 MPH 44.1 MPH
A 52 20 2.60 40.5 MPH 40.6 MPH 46.5 MPH

- 47 18 2.61 40.3 MPH 40.5 MPH 46.3 MPH
- 47 19 2.47 42.6 MPH 42.7 MPH 48.8 MPH
- 47 20 2.35 42.6 MPH 42.7 MPH 48.8 MPH


NOTES:
A - Likely will not fit Savage without mods (gear combo is too large)
B - Likely will not fit Savage without mods (gear combo is too small)
* - "Top Speed" is controlled by many things, as stated above, thus these speeds are intended for comparison purposes to help with clutch bell and spur gear changes, and also to compare the potential top speed difference between the available Savage transmissions.

I used to post these numbers myself BBB.

http://www.rccoh.com/IMG/land/off-road/ ... .speed.gif

But we all know a Flux will easily exceed these numbers, so I stopped posting it.

All I can say about my Tekin powered converted Savage is that it's too fast!  lol

I am not going to come down on nitro, it's still cooler.  :)  (And I know you have some bad azz mills too)

But if I am doing speed runs or drag races, it's 6s or nothing.

And I don't run Flux oem gear either.. (hee-hee)   :)

I am not the author either.  I just meant to agree with you that they are great numbers.
No worries man.

I dont know how fast my savage goes, but the ercm modified picco 28 is dam fast for the 50 mitre straights on any given off road track if you have your gearing set right thats for sure, i will leave the speed runs to the guys that are slow off the line

my original Savage picco .26 with 16/47 and high speed 3rd gear-------46.8 mph

my buddies savage xl 16/49, untouched xl tranny and LRP .30-------51.7 mph

Both of these trucks were ran on a flat parking lot with a Garmin Nuvi GPS strapped to them!

I am hoping the picco .28 that I am buying will outrun the LRP!

Firestorm is getting there!

the aim is 100km/hr.

current setup runs warm, but not hot at all, motor is about 65, esc is 45 degrees Celsius.

these were on road tests, running road rage tyres  8)

Image

Image

maybe I should aim for 60mph?

I'm up to 59.4652231 mph...

only 0.5347769 mph to go!!
