(0003596) Kartaviy (viewer) 2016-01-12 17:44	Разговаривал с бывшим танкистом, он управлял Т72 и Т90. Говорит что максимальная скорость езды задом 15-20 км/ч

(0003597) reyhard (administrator) 2016-01-12 17:56	we need more intel than that. I hope you understand since otherwise everyone could tell their info from "trusted" sources.

Besides I have contact with US soldiers that served on these vehicles, among them one of the renoved author of articles for ARMOR magazine, James Warford, I can ask him about such data concerning M1 and M2 series. T tanks reverse speed as stated in manuals is very slow. Kartaviy your source just lie to you... just as these "articles" you use as a source. ;) PS vehicle mobility and speed forward or reverse do not depends on vehicle weight per se, but also on engine power, it's torque and transmission type used. T tanks use mechanical transmission (planetary gearboxes) that were never designed to provide greater speeds at reverse gears, as there was no such requirement, doctrine of Soviet and then Russian army at that time was not requiring high speed for reverse gears. The only T tanks that have high reverse speeds are T-90AM/SM, T-14, T-84BM "Oplot" and some modifications of T-72 tanks made outside Russia, like Polish PT-91Ex and PT-91M.

(0003601) Damian (reporter) 2016-01-12 23:48	As I said, vehicles with hydrokinetic transmissions can drive as quickly as 30-40 km/h on reverse gears, tanks with old planetary mechanical gearboxes drive reverse very slow. https://www.youtube.com/watch?v=f5XUQ2beGfM [^] https://www.youtube.com/watch?v=lEdO93OLSh4 [^] This is a tank with hydrokinetic transmission. A tank with planetary mechanical gearboxes can't do that, neither drive quickly on reverse gears, neither pivot (neutral stear). These are facts.

(0003609) Kartaviy (viewer) 2016-01-13 10:19	I believe, but the problem lies elsewhere. Why he climbs the mountain faster backwards? Is Weight should not be taken into account?

(0003612) reyhard (administrator) 2016-01-13 10:42	it's because of usage simplified gearbox - it's supposed to reduce number of physx quirks. GearboxRatios[] = {"R1",-2.0,"N",0,"D1",1.0}; changing ratio of first gear will change also max speed. maybe adding another gear would improve that thing a little.

(0003616) Damian (reporter) 2016-01-13 11:40	There is also another issue, right now not all of our Abrams tanks have correct weight. Because due to time scope, USF will have only the most modern ones, it means all of them should have the same weight. M1A1SA, M1A1FEP and M1A2SEPv1/v2 all weight 63,5 metric tons empty, and 65,5 metric tons combat loaded (full fuel and ammo load). The current differences are because initially mod had older models, but these were changed to the newer ones better fitting mods time scope and real world situation, tough weight of the models stayed the same. At some point this probably gonna be changed.

About reverse speed RHS team is right. All T-72/T-90 canoot reverse fast - its their big disadvantage. Just like those tank was made to rush forward only :D About driving uphill there comes problem that are mentioned - weight are almost not calculated by game engine i guess - i have done very various things with Merkava and T-100, and they act like Lamborghini. Its not big problem i saw only 2 times abrams on reverse gear climbing on the hill - and i was wondering what this guys was doing :D
