a little laugh i got

[brushlessboy16]

just like the guy i was talking to on rcu, trying to claim that his MM 7700 has lasted 2 years running on 5s.....hes telling me that hes turning 87k rpm and wont take no for an answer.... ugh n00bs..

[Takedown]

Kids these days... I mean look at how he types. Would you feel confortable buying from him. He doesnt even have any pics of it either.......

rcuniverse.

[Arct1k]

Actually I think someone here has been using a 7700 on 5/6s for short bursts for drag racing and was having no issues...

lol im glad i added so much hillarity to the board, and about maxamps, i agree are overpriced/underrated. some say that true rc are the same cells, but seems like trc are so much better, but i just picked up an evo 25 4900 4s pack off ebay for 81$ im hoping its still good lol, i got it for a steal

[TexasSP]

I love his answer to linc! Geared to the max.....

I so wished I lived in maryland right now!

this thing is geared to the max.. it has a jato 54 tooth spur/and emaxx 22 tooth pinion... and if this e revo dosent do what i say ill give ur money back and u keep the truck..... i live in maryland u can come here with any 1/8 scale monster truck with any motor u like and ill whip ur ass and still sell u the truck..... and no trades this is custume made by me.. if any one on this site thinks they can beat this truck we can race for money before i sell thanks///// also if any one would like any mod work done or gas to eletric let me know..ill give u the best set ups availible thanks...any questions call 4435216193 no low balls

heres a laugh


RCU NOOB-im doing about 84,000 rpms with temps at 270f esc gets real hot tho. but never solder melting off the board so i think im ok. i watch my temps close i no im not susposed to but its fun, if i ever have probs i can gear down upto 5 teeth on my pinion and a bunch on my spur also it rips im happy it runs good that dune set-up is wild




Brushlessboy16-
That proves that your lying... NO motor can handle 84,000rpm.. it just doesnt happen!

even Neu's only are rated to 60k,

not only would your bearings self destruct but the rotor isnt balanced to that high of an rpm

If its getting that hot it would de-magnetize the rotor and render it useless.

N00bcake-
well whats 7700 times 11.1? 3s lipo? It runs very very fast, i run my 2s most of the time but for being faster sakes i can drop a 3s cant i?

Brushlessboy16-
yeah not taking into consideration driveline drag, wind resistance, and the Loaded KV value of the motor.... still ur not turning any where near 80k



Mind you at this point about 4 other people joind in trying to prove this guy wrong... Myself, Takedown, and Trev8913....

he pm's me saying that someone on THE TRAXXAS FORUMS said it would be fine and could run 3s all day..

Just annoys the crap out of me when people soak up wrong info

[lincpimp]

I hit him up with a reply, hope no one buys it...

[What's_nitro?]

I might take him up on that "money back guarantee".

I'll buy it, make a video of it not going anywhere near 60mph, and get my money back! And keep the truck!

[hoovhartid]

"i need this gone asap,,,, so this thig has a mamba max esc and a fegio 1500kv motor..this thing will beat all gas trucks including the big mgt 8.0.. it has been clocked at 61 with 3cell 4500 lipo..it is rtr asking 500 obo. need the money .. so hurry and get this truck"-MD DRIVER

I must apologise to MD Driver...

i didn't realise his thig had a fegio motor. I thought it was a fiegao...my bad. I didn't realise the mgt 8.0 was a gas truck. And when he said "clocked at 61" I assumed he meant miles per hour, not parsecs in neverneverland. Maybe he means 61 in its own scale?



"i need this gone asap,,,,"
ok then click your heels together three times and say "theres no place like home"





I'll give him 500 schrute bucks for it...(watch the office)

they have the same ratio as unicorns to leprechauns

by the way... thanks Big Greg, I needed a laugh

[lincpimp]

I guess I rattled his cage a bit, here is a PM I got from him. Good luck deciphering it...

"i made a mistake by saying it was the fegio motor///its 2 the velineon with the maba max esc that did 60...and ill say this again the stock spur gear for the revo is a 38..but like i said im using a 54 tooth jato spur with a 22tooth 32p pinnon .. just because you have done many convertions dosent mean what i have wont kick ur ass............mycam is not really clear but i have a camera phone until i buy a new cam friday... my shit is fast foreal.. come to maryland and ill race any thing u bring that is 1/8 scale and ill garante that ill beat u by 10 trucks..ps bring ur wallet.. do all the math u want4435216193 call for any ass whipins"

Heres the calc info with the 3500kv velineon motor:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 2.111111111111111
Other Ratio: 1
Spur Tooth Count: 54
Pinion Tooth Count: 22
Total Voltage: 11.1
Motor KV: 3500
Tire Diameter (inches): 5.75
Tire Ballooning (inches): 0.5
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 2.45 : 1
Total Ratio: 14.74825 : 1
Tire Circumference (inches): 21.21 inches (538.63 mm)
Total Motor Speed: 38850 RPM
Vehicle Speed: 52.9 mph (84.97 km/h)
Estimated Adjusted Speed: 49 mph (79 km/h) - 7% loss
Effective KV Value: 3500


Thats a bit closer to the 61mph, and I figured the wide ratio 2nd gear. He may have taller tires... but they would have to be about 7.5inches tall to get over 60. And I really do not see the velineon pulling that kind of weight.

[lincpimp]

This guy is 29 according to his profile on rctech

[Arct1k]

You should send him back a few pics of rides here - thought the MT record was 80+

How about the maxxx with a 1527!!!!

[bl-is-future]

some people.

[TexasSP]

I don't think a single velineon could pull 52 and not choke or kill the controller.
