    Im looking to purchase a new giant scale 1/5th but want to talk to some people first.
    Currently I own a Traxxas rustler with a 3.3 which is a nitro engine.
    My little Rustler will run about 60 or 70 MPH easy and from a stand still will burn the tires down.
    Even starts to wheelie at 50 plus MPH.

    Im currently looking into buying a 1/5 scale 36cc Rovan or a Redcat dune runner only because of the reliability of the large two stroke motor.

    Only problem I have seen so far is that the Large cc 1/5th scale cars and buggies look slow compared to my little 300 Dollar 3.3 Rustler.

    Every video I have ever seen of a 1/5th scale gas buggy or truck they all barley start out from a standstill. The large 1/5th scale buggies just do not seem to have the takeoff power that a less expensive nitro car has.
    Not sure why so many large scale rc cars have wheelie bars.

    My little Rustler will burn the tires off from a stand still and will pull the front end up all day long from the power to weight ratio but I just don't see that kind of power from the 1/5th scale cars and buggies.

    Anyone have any input on that subject?

    Seems like the large 1/5th scale cars are asking a lot of the gears with all of that weight and the big cc motors.

    Id love to get a large scale 1/5th scale but don't want something that just gets around. For 700 U.S. Dollars Im thinking it better burn the tires off. At least thats what my little 300 dollar Nitro Rustler does all day long.

    Depends on how how deep your pockets are bud.. Just sheer size and sound of 1/5th scale is a hundred times funner than 1/8th scale..By no means are they slow. Newbie 1/5th scalers are generally intimidated by the size and sound.They sound like a dirtbike with tuned exhaust and some weigh 40 pounds!! This is what im currently building..

    imo it gets to a point were it gets pointless with these big ass engines as u cant really rag it around left/right/left/right pinned as all it can do is go fast in a straight line on 2 wheels......which...imo gets old real quik..(but this is jus my opinion...each to there own as we say;)).....as with any rc what likes to live on its rear wheels...the novelty soon weares off...:rolleyes:...i like to beable to keep it pinned and make quik sudden turns ...slide it about with out fear of it rolling and wrecking its self once all that weight comes to a stop...or u hit sumin ..:(.. ....

    Im sold

    I want to get a 36cc Rovan. All parts are HPI compatible.
    They are around 569 U.S. dollars.

    Ive watched several reviews on the Rovans and they are not bad at all.
    They are price brand new with the big 30cc motors for as little as $449 U.S. Dollars RTR and go up with options.


    Wifey told me not a good idea to purchase a 600 Dollar RC car but she agreed only if I can sell something to cover the cost.
    Sweet
    Ive got my Chopper forsale for $8200 U.S. Dollars, So if anyone wants a chopper. LOL hehehehe

    I cant wait.
    Anyway im kiind of surprised that these Giant scale 1/5th cars are not 4 stroke. Lately I have been seeing all of the weed eaters at the local hardware store coming brand new with little 4 stroke motors. They sound all thumpy.
    I was looking at a weedeater the other day that had a 4 stroke and it looked like it has the same bolt pattern as the 2 stroke.
    That would be the shisel to have a 4 stroke thumper in a 1/5th scale.

    Building a twin because there just badass, Got a Mtxl for bashing love it, got a erevo brushless for even harder basher, got losi 22 4.0 buggy for track racing, got a bully rock crawler for the rocks, got a cyberstorm 32inch on 6s for the water, got a Goblin 700 heli for 3d,got a Yak 54 30% gasser airplane for 3d.. I got pretty much everything covered.. So having a twin is not really overkill or boring when you got pretty much all angles covered..LOL

    Yee Haw

    Proud new owner of a 36cc Hot Rod screamer.

    Spent about 2 hours just letting the little guy idle and cool down then idle and cool down. Did that for nearly 2hours to get a good break in.
    Ive been using tru Fuel which is ethanol free petrol aka gasoline with a non synthetic 2 stroke oil. Now that the motor is broken in properly I ve switched over to a synthetic 2 stroke oil.

    This thing is a tire spinng wheelie popping Hot Rod.

    Im seriously impressed.

    Seriously fun.

    Rovans are the shissel.

    Very first start up was nothing, only one pull with choke on and it popped off, I immediately turned the choke off and it started up right away on the 2nd or 3rd pull.

    Cleans up really easy after each use with some air.

    Serious Thumbs up for Rovan.

    Thanks
    I appreciate it.

    I actually spent about 3 hours just looking over all of the nutts and bolts and looking at how everything was put together.
    Now Im just trying to validate that the motor is in fact a 36cc besides some stickers saying so.

    Does anyone else use compressed air to blow out the cooling fins and blow off all the dirt after each run?

    Harbor freight has a nice little High flow nozzle that fits down under the case of the motor and literally blows all of the dirt off everywhere.
    Makes the little guy look brand new again in no time.
    Its great.

    If you don't have access to a compressor I would think a computer duster Air can could do the same thing.

    I sure do..Air compressor comes in very handy. I actually consider an air compressor a must have.I see guys that wash them off with water.. I don't think thats good..I keep mine clean looking just blowing it off..

    Yes
    compressed air does wonders on a dusty dirty 1/5th scale.

    Thumbs up.

    I would never take a water hose to my little Rovan. Prob would not hurt it but Im not gonna do it. :)

    For me, keeping the motor up and running is all about keeping a fresh well mixed ratio of fuel in her and keeping those cooling fins free of dirt and debis.
    Recently picked up a little Pull start Cover to help filter out those cooling ports on the pull start.
    Those must remain clear of debis in order to keep the air flowing across those fins.

    Seriously important.

    I found the crank case filter to be a needed item as well, if you run at all in grass.

    I have hosed my trucks off with the garden hose a couple times but I pull the engine and electronics off first, we've had a few muddy days at the track and the air hose just wasn't getting the job done.

    I don't even start my motors new, until I have outerwears on crankcase and pullstart. The crankcase outerwear is much more important because debris will get in there for sure easily. That will cause flywheel damage!
