Rc Car Gearing

This app need alot of work my traxxas stampede from factory is capable of 65+mph/100+kmph give or take abs this app os telling me that my monster truck is only capable of 56kmph with the highspeed gearing and a 3s lipo yall need to go some research and up date this app

i put in what i had in my rc sc truck and its numbers werent even close to what i actually get

Great app. Easy to use. Needs updating though.

So helpful.

With a 3300kv motor, 50 tooth spur, 28 tooth pinion, and 3 cell lipo it said i had a top speed of 0.02 mph.... Wtf?

Pretty close numbers. Nitro is cool. Hope you don't plan on using nitro racing application though. I have about 500 dollars invested in my electric RC buggy. I have beat every Nitro that's been put against it. And some of these guys have almost 2 grand invested in their cars. While these may be nice nitro cars and all, I haven't found a gas powered RC that will beat a high end brushless RC. My car: Traxxas bandit, 4600 kV Castle kit, with 6400 mah 25c 3s lipo. 121.6 MPH using police radar. Front off ground.

This app allows me to keep all my cars gear ratios in one spot. I can change spur gears or pinions at the touch of a button to see the effect of the overall FDR.

Basic and easy to use interface, maybe some stuff explaining drive ratios but a google and you can find out most of what you need to know. Only thing is the settings menu has missing text in lollipop, not sure if that's a app thing or lollipop thing, but it should be fixed.

It would be nice if u would have gas motors but its nice to know how kinda fast it goes

Could you add 1/18 scale option please ?

simple, does what it says, good app.

Very usefull, but it would be nicer if you had a preset for different trucks, instead of the final drive ratio. That would make things so much easier!

Cool app but include nitro. Who drives electric?

So ez .....

Not everyone uses brushless and lipos

Need option to select pitch

Works great on the Motorola Droid

Great for electric! Thanksgiving

Its awsome

Great app. Simple but convenient

This is a good thang

Nice

Saves the confusion on race day :)

Make one for nitro

Needs nitro setting

it sucks

This is out of date, considering speedies have boost and turbo functions. This app doesn't take these new settings into use and there for the top speed is incorrect. APP NEEDS MORE WORK AND MORE USER INTERFACE TO PERSONALIZE TO CORRECT VEHICLE SPECS.

Great app simple to use for a noob like my self. :)

I think application is the best you can find and,everyone should use it .

Wow simple and easy to use with no requirements I cannot wait to put the figures to the test but I am very hopeful I will pass this around like vd in Europe

Simple and insightful. I like that I can change kv, spur, pinion on the fly. Landscape mode would be nice for my tablet.

To all the people saying they need a nitro version there is not a way of calculating speed because not all nitro motors will run the same speed

I wish there was a help function so you could understand what the diff ratio and the gearbox ratio are and how to figure them out.

BRAVO! The only rc app in my galaxy tab others just a waste of memory.

Really a great tool, when there is no computer or charts at a race. Great job instead results.

Sucks balls...put the specs for my brushless losi with lipo in and it said it would do .01mph lol worthless

Really good app easy to use. Get it right up the nitro racers.

Nice app. But can you please add nitro cars and trucks?

Great app, no need for nitro. Brushless is where its at.

Agreed, needs nitro engines. Otherwise great app.
