IS this a good reliable, strong motor?
One of the best... I got 14 gallons out of my Ws7II before the piston exploded. Rb's are known for long engine life and tons of power
Very good engine. I had a WS7 and it screamed!!

Woah
Eeh nevermind this thread now.....I didn't end up bidding on the engine, and also leisure told me that it was less of a torque motor and more rpm.
Ya know a low end pipe woulda done the trick
That's allright...I think if it doesn't sell, I'm going to pick up a new Axial .28 engine. It fits right in there, nick at leisure busted one out for me to see/fit in there....Looks cool too.
lol...so your going to go with a no name "Axial" instead of a proven S7? lol....The S7 has PLENTY of torque.

If you want to see a S7 in action check out FINN's TTR ST next time your at leisure. Pushes that 9lb UMT around the track with no problems and is very torquey and quick. S7's are awesome motors.
I wish I would have known earlier....It ended for $91 shipped.
oopsss looks like ya blew it again!
I love you Rocco!!!!!!!!
How much are they new? Or do I even want to know...
not too bad like $250-300....lol
if you want a good motor cheap get a Novarossi .21BF for under $200 and almost just as fast as a P5
Dude, I'm going to go die now after missing that deal...






I think, if I get anything, I'll just get the axial. May as well give it a try.
the new S7's are cheaper than the Ws7II X3's but if ur gonna spend 250 on a motor why not spend 300 for an even better one Wink

its "pray" bro LOL sorry i had to sounded too funny the other way hahaha
OOps lol...Yeah it's pray not prey....Hehe yeah you have to eat the motor and trans and then it'll work.
Ok. I was just wondering because I don't know of any tranny gear hop-ups like there are for the maxx's. Maybe it has stronger tranny gears?
