just thought to share my experiance with my xrider sagittarius 1/4 scale off road bike . i had dabbled with rc bikes in the early 2000's , had a thunder tiger road bike clone , and a 1/4 scale off road bike from hobbyking [ i think ] . the road bike worked well and i learnt to ride with it , the offroad bike though was never a success , disliked the rear wheel mechanical gyro . it was ''controllable '' up to a point , but forget about accuracy to put it where you wanted it . i now have both the losi promoto , [red one painted yellow] ,and the xrider sagittarius , i have had the losi for a couple of months longer than the xrider .
for my set up i used the reciever that is in the losi , mounted in the same orientation , thinking to have all the features of the losi system , namely the extra stability system [ electronic gyro ] , and the different riding modes in the reciever , along with the incorporated mechanical gyro .[ both have ] . however this system is not compatable with the xrider , as it interfered with the steering input , even with a ferrite ring in circuit , causing loss of steering control . big thank you to dave [ holeshot hobbies] , for the phone discussion concerning this issue and all the advise on my set up, is excellent service . my only thought is that the radio frequency put out by the mechanical gyro was causing the interferance , as the gyro's are different on both models . it might be possible to filter it out , depending on how much one wanted the ''ride'' modes on a switch, instead of your finger .
replaced the reciever with a four channel spectrum surface reciever , which fitted in behind the brake servo's , between the frame side plates and ran the antenna out the rear of the bike . fitted the rear brake disc and servo , diddn't like the bmw blue/white helmet , so painted it black . i also added velcro to the seat and rider , to assist in carrying it by the rider . in case of loosing the seat fuel cap and body clip during a battery change , i cut the bottom off a swivel and glued it to the fuel tank [as to turn ] , and made a small trace wire and attached it to the brake cable , a cable tie is on the rear body clip , so they both stay with the bike , and not in the grass .i also put a s/s mesh screen over the r.h.s. motor gear train to stop possible debris causing a gear jam and are running 8mm nylon rod posts on the rear holder with losi wheels , for my lean bars .battery is a 3 cell , 4300 mah , gens ace shorty pack .
i have upgraded the steering with the dual hydralic damper steering upgrade/bearings , and added 2mm of preload , huge improvement . absolute minimum headshake and very responsive . upgraded the brake servo's to 2, kst X15-1809 V8.0 [18KG@6V ] , bit of trimming to get lead in , and a, savox SC-1251MG [9kg@6v] for the steering , drops straight in ,centres better .for more front brake force i re-routed the cable from the caliper straight to the head/triple, over the handlebars, and straight to the cable/servo mount , miniumum bends/friction , and a lot more force transferred to the caliper , better stopping power . i removed approximatly 75mm of the outer brake cable sheath . the seat assembly keeps the cable down . i have removed all pre-load on the rear shock , she sits better and has improved handelling .
she is now very responsive , slightly quicker than the losi , better top end speed . the slow speed handelling is also superior to the losi , being very close to walking speed . the narrow width of the xrider [ narrower than the losi ], gives it another slight edge over the losi , being the smaller turning circle/radius . the bikes physical behavior is more to scale realism than the losi , she sits and turns a bit more stable , the rear slides more realistically ,i think because having only one gyro , there is not the ''fight off'' that is apparent in the losi front forks shake , when the two gyro's fight each other , same when the front wheel is off the ground .
the xrider seems also quite durable , through the set up process i had many a crash , endo's and tumbles ,including one at half , to three quarter throttle head on into a tree , nothing broke or needed replacing , testament to the quality of the product . i am impressed with this model and find i am taking it out more than the losi . i get between 7 - 10 minutes from a battery . also the xrider is considerably lighter than the losi so is easier to carry around and set up .
i noticed on my losi when i was working on the front brake , [ have a few upgrades on the losi ],that the outer brake cable would ''shrink'' at full brake . you can see it , look at the distance between the brake cable and the handelbar , apply full brake and watch the cable get closer to the handelbar. this does not happen on the xrider , why , because the losi outer cable sheath is plastic tube , and it compresses under load , thus stealing force from the caliper , the xrider has metal in the brake outer sheath [ saw it when i cut ], like a real brake cable , and does not compress , just little things that shine .once again quality . i replaced my losi cable outer with a inner core from a aircraft flexable push rod , and made a big difference to the stopping power . sure the xrider takes a bit more work to set up , but isn't that what seperates the avid modellor from the hobbyist . for the quality and performance of the xrider sagittarius , one will not be dissapointed .
yes i was, a bit dissapointed with the xrider's , first runs , compaired to the - whack a battery in in and jump over houses , go through brick wall , ?, l.o.l , with the losi . though now ,a completely different bike , been through the learning curve , and in my opinion the xrider sagittarius is on par with the losi . the ''goods and bads '' of each, cancell each other out , if you are after ''tricks'' , [wheelstand], and extreme conditions , prefer the losi . if you are after a fast , responsive mx track racer , then prefer the xrider . for stay on the ground performance, i think the xrider wins ,depends on eveyone's style . only thing i do know is - MY XRIDER IS A BLAST
hi tom , sorry for the late reply . glad you enjoyed the video , yes was a bit of work , but it did work . unfortunatly the result was a bit of a anti - climax ?, as when running the bike , the steering does not move far enough to really notice the drivers head turning , unless at slow speed and sharp turn. mate your video link is fantastic , way to go for realism . quite a while ago i had a cheap plastic 1/10 scale bike that had the moving rider , no head movement though , it handelled great and looked like the real mckoy ? . me being me i opertated on it and converted it into a brushless set up , went really well , untill the plastic gears melted ? , l.o.l. .my wheelie module has turned up , will get into fitting it soon , did you have any problems fitting yours ?. and yes i use my losi in the super rough area's as i feel it is a little stronger against possible damage . i agree with the ''dont let the buggy mates thrash it , or throw it into some extreeme conditions , is too good a bike to mis-treat like that .hope both of our weather starts to settle down a bit . the crs took a little ''calming down '', in the riding style , compaired to the losi , to have a nice flowing circuit .more finesse required then nice and smooth . the losi would not dissapoint , they are tough as , but a big increase in model weight , and a couple of tricks in the start up proceedure .will be interesting to see how the 3000 kv motor goes , should be a blast . keep us informed . and with the xr8 pro , it should blast off into space , l.o.l. , definitly keep one informed .still working on a video , bit going on this end , but will add more , as i can ,
Your thoughts about the learning curve to CRS from the Losi, and that you´d prefer the Losi in extrem conditions, made me think that the CRS is in Fakt perfect for me, but not for letting my Buggy-Club Friends try it out, nor to run it in real bad Weather, what we have her the next view month. As I´m hoping to motivate a view Guys to go for a RC-Bike and race together in future, I couldn´t resist, as I saw a 500.-€ Offer for a new Red Losi at Amazone. It´s 629.-€ regular here, and the first who jumps in, can have it, little used for 500.-😁
hi tom , good to hear you got your rear cable installed . and with the goods coming tommorrow , ya hoo . with the rider ''falling off '' . i was concerned that his hands would come off the handlebars , and drag the rider off , so i got two small plastic washers and screwed them onto the ends of the handlebars . and his hands don't come off . still pivots to fit battery . his feet are a good tight fit on the footpegs , and with the bit of velcro on the seat , if needed can pick up bike by the rider . were you riding when he fell off , or was it at home , fell onto the floor ?.
the weather ?, the cold , we australians don't really know cold ,its 34* c here . made me remember when i had 16 months in paris . 12 in london ,at that low temperature the plastic would be very stiff and brittle , and a lot of other things ?, bugger mate , l.o.l.. like your repair , i possibly would have done something similar . i like the way you cannot see your repair , well done .
also just for fun and for playing around with the models , i made my losi handlebars / arms / head, all move with the steering . is on youtube , search ,, losipromoto - richard davis ,, L.O.L. . tried to put a video post up , but my video is too long , will have to look into it . keep it up mate
hi tom , glad they helped . looking forward to the wheelie mocule , yes lets get onto some fideo's
hi tom ,bummer about your esc . she is, a tight fit , being so narrow . similar to a rc glider , minimum room to mount the equipment . would have been good to see how it operated ?. am glad to hear [ after the steering , l.o.l. ] , that she is easy and precise . mine is , sparks and all , ya hoo , good stuff . the clip on the scratch bar is good idea . i have found no noticable difference in general running between my crs , and my losi . i run on open parks/dirt , have not had either at a rc track , to try there jumps . i have had the crs 30 - 40 cm off the ground , no problem . more with the losi . also i think the helmet colors fit better with your blue one . the wheelie bar has saved me on many occasions too .
yes a very good lean angle , and impressive slow speed handeling , excellent turning circle ,yes , plenty of power , supprising . throws a good rooster tail in the dirt . i havent tried mine on two cell . would need a very good transmitter to play around with the brake balance i have a spectrum dx5
yes the rear brake cable had me going for a while as well , i also have a four channel reviever . i used a ''y'' , lead , or a ''splitter'' . the one channel feeds two servo's , so will apply both front and rear at the same time . only problem then , is any individual adjustment to the brakes front/rear needs to be done physically /mechanically [ loosen rear a little to let front come on first ?] . am still playing with my mixes , to see a way around this , or get a five channel reciever , but is working ok for now . yours is looking good, well done .
between the motor and the frame sideplates , there is a small gap . i ran my rear cable from the swingarm , up and through this gap , on top of the motor .
then i went across on top of the motor , to the other side.
brought it out through the same frame/motor gap on the other side .
then out and to the servo/cable mount .
hope that helps . might have to shorten the outer cable sheath . [ love my dremmel ] .i have thought about shortening the scatch bars , still experimenting with mine , let me know if you do , and how it went , i like not having to go and pick them up . a hobby shop might have some spring steel rods of correct size , for experimentation . plenty of power for offroad , is a blast . can't help but put a smile on your face .how do you do the weightbalance thing ?.have fun with it mate and let us know how it goes , i am trying to make a short video , and will post . have just ordered the wheelie module , for fun .
when the scratch bars fit and the grub screws hold , remove and where the scratch marks from the grub screws have marked the scratch bars , file or grind a flat spot at these marks , the grub screw will sit a lot better on the bar with a bigger contact area , and hold better . blue locktite for security . or finger nail polish .
on the front , is the exhaust pipe push in ?, i tried to get mine off , but it seemed to stop , and i was not game to pull harder .
hi tom , top hole mate . i like building as well , very rewarding . looks like she is coming along well , and yes you can't rush these things . the gyro in the crs is fantastic . varying the flywheel./ gyro speed is a interesting thought. would lowering the speed reduce the effect ?. to try lower , check if it will run on 2 cell voltage and use a volt regulator from the battery to its plug?. or in the gyro channel on the transmitter ,try reducing the travell end point to 50% , theroretically [?] , it should give 50% of gyro speed ?. if that worked you could have a trim on the gyro channel to a slider or knob on the transmitter , that could adjust while riding ?. the steering dampers look good hey ?. flywheel connection should have a small plug coming from the speed controller , the plug of the flywheel plugs together . the white/black servo lead wire goes into you reciever gyro channel port .
Hello from Bavaria and thanks for the detailed review.
I´m Tom and my Kit is comming tomorrow. 😁
....had big fun today with my "Streetfighter" CSF411 and the amazing XRider Wheelie Module. Comming from this "non Gyro"- bike, I think the CSR is the better choice for me. Would be nice to share some Thoughts, Pics and Tips here in the Forum. Hope my "bavarian"-English is not to bad.
Thanks for such a detailed and comprehensive review of your experiences with the 2 bikes. We could not agree more 👌🏻👍🏻
