just got one! and thanks to the info posted up here rc groups, and brett's blog, I have had a great start to rc dirtbikes! Decided to start out with the qrf400 as Im hanging for the venom to come out! Also my first brushless and lipo experience.

I have made mine a replica of my dirt bike, a husaberg fe450. Just blew up some pictures of my bike and printed out the fairings and gas tank on paper and covered it with contact, came out pretty bad with bubbles and whatnot (by my stds!) but will do until I find some printable decal paper/vinyl at a reasonable price. Hobby king really need to come out with a clear body, would have made life much easier.

Any of these will work nicely:
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6527
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6532
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6534

Depends how fast you want the bike (these are 2600/2900/3200 revolutions per volt - kv).

Keep in mind that these motors come with the round shaft - you will have to machine the groove for pinion yourself - that is easy if you have dremel tool at hand.

Also you will have to solder 3.5mm bullet connectors on the motor.

Don't forget http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8998 pinion too.

Also KD36 motors will work but B36 (the ones in links) are cheaper. KD36 motors have the groove for pinion grub screw.

Have fun!

thanks for the advice Kristaps, I will probably go for the kd36 motor, just got to decide whether 2700 or 3500 (overkil??) as I dont mind spending a few buks more and they bolt straight in without extra soldering. Hopefully the 3000kv is back in stock real soon and then i dont have to decide!


I found some printable waterproof vinyl at a reasonable price here http://cgi.ebay.com.au/A4-Self-adhesive-Inkjet-Vinyl-Outdoor-Waterproof-/110616255969?pt=UK_Computing_Printer_Paper_Accessories_ET&hash=item19c13e1de1

will have better decals for the body soon!

AFAIK from KD36 motors the best would be KD36-60-08L 3000kv - it is a tight fit but works well. If you order other motor from kd36 lineup just make sure the can is 61mm or shorter (B measurement in motor diagram on product page). XL ones would be too long to fit between chassis side plates.

Soldering would still be required because they come with 4mm bullets and if you have turnigy 60a car esc - that has 3.5mm as female counterparts.

well I ended up ordering the 3500kv, couldnt help myself! got a 13t and an 11t on the way as well, I dont really want a 80kmh bike thats why I went for the lower pinion gears.

while im waiting for the motor to turn up, I made a quick wheelie bar to stop some damage to the bike. Just a couple scraps of aluminium and a rubber wheel that is actually a rubber wedge out of a mountainbike mud guard :)

I put an extra oring in the front fork to try and get a bit of dampning, I also added some 30,000 wt diff oil to the forks, but that was too much now it takes about a minute to return to full travel, still thats progress!

oh yeah, now also running 3000wt oil in the rear shock, and it is close to showing some dampning, probably could do with a little heavier oil, 4000?

has anyone ever tried to fit a steering dampner from the duratrax or made their own up?? I think the steering could be vastly improved with one or even a direct linkage and a servo saver, though I think you would need a pretty tough servo to handle that!

Tried the bike on cement the other day, man was it woeful! no rear grip whatso ever, I guess the contact patch of the rear tyre is very very small when on cement cause it was sliding out at the slightest lean or throttle application

I have cut off all the bumps of my rear tire to try it on pavement. Haven't had opportunity yet though. As for the steering linkage - i have put on a servo saver and steering arm assembled from traxxas parts, that made it more responsive.
