re: Life of one YETI - Tom Frajer's Axial Yeti build log Here is short video of steering response of my Yeti - full yupgraded steering to Vanquish aluminium parts and Holmes Hobbies BLS HV500 servo. I'm pretty satisfied with this "thumbsup" <iframe width="560" height="315" src="https://www.youtube.com/embed/Z2GeTj-Ou7Q" frameborder="0" allowfullscreen></iframe> |

After this, I will move on to painting my Baja bug body that I already have on shelf to give some personality to my build. Then i will do some lights and maybe sound module. I'm looking for some racing in future but right now this is just a fun thing 8) There are not any U4 race events in Czech Republic. Some are in Hungary and I hope this will change in future. I will show this rig to some folks and hope I will motivate them to do something simillar. I can attend to some Short Course events here in CZ, so Im also planning to build some nice Trophy Truck body for this rig - will update this thread so stay tuned :) |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Skidplate installed. Ready to make some scrathes tommorow. I also swapped MIP to correct position - now, it slipped just right into transmission output shaft without any problems. When dissasembling MIP, I stripped set screw on it - had some hard times to get it out, but it gave up after using blow torch... http://uploads.tapatalk-cdn.com/2016...8cd0c2ff18.jpg YETI :) What I really like on this skidplate is the low weight it adds. 238 grams. Now I shuld run 3S with this rig to keep up with the weight of upgrades... http://uploads.tapatalk-cdn.com/2016...2f79433859.jpg Centered pumpkin axle by Vanquish - so sweeeet! http://uploads.tapatalk-cdn.com/2016...d67720e7f5.jpg Ready for destruction? http://uploads.tapatalk-cdn.com/2016...cc1342dab9.jpg |
re: Life of one YETI - Tom Frajer's Axial Yeti build log I didn't notice you lived in CZ till I read your reply. Two my favorite rifles come from over your way I love my CZ 452 .22LR and 453 17HMR. Do you live close to where CZ builds these sweet little squirrel hunting guns? |

Česká Zbrojovka (CZ) have factory 200 miles fom my city (https://goo.gl/maps/vKSpBySoUK22). It is almost on the other side of our small country :) I'm glad you like CZ guns. They also make something bigger for bear hunting: CZ 805 BREN A1/A2 - Assault rifle - Products Or famous CZ SCORPION: CZ SKORPION 61 S CZ SCORPION EVO 3 A1 |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Here comes the destruction! Traxxas Jato rod end on rear titanium link proved to be the weakest part of whole setup. Had rollover on high grip surface (asphalt) in full speed and it broke. Today's runtime approx. 15 minutes :) Any ideas on more robust rod ends than Traxxas TRA5525 ??? But still better to break this than someting more expensive... http://uploads.tapatalk-cdn.com/2016...695d67ce54.jpg |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Mounted stock rear shocks into dual shock configuration. Filled them with 30 wt oil too. I also swapped springs on front suspension. Now I have red ones (hardest) there... http://uploads.tapatalk-cdn.com/2016...cc658aaeec.jpg http://uploads.tapatalk-cdn.com/2016...a7935cf476.jpg http://uploads.tapatalk-cdn.com/2016...ec18e54b4b.jpg |

UPDATE: No it was not overheated motor, I just finished battery :-D Still noob :-D http://uploads.tapatalk-cdn.com/2016...b31b829c39.jpg |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Grrrrr, again! :-D Hope I will not run out of traxxas rods until RPM ones arrive... http://uploads.tapatalk-cdn.com/2016...9e10ca89b1.jpg |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Rear end is little bumpy when passing obstacles (such as holes in the road). Any suggestions? Lighter shock oil? Or thicker one? UPDATE: Found this. I will study little bit: http://home.scarlet.be/~be067749/58/bug/print.htm |

re: Life of one YETI - Tom Frajer's Axial Yeti build log I was wondering how much faster Yeti is on 3S compared to 2S. Found some guys measuring top speed using GPS. Result was 17.4 mph (28 kmh) on 2S and 26.7 mph (43 kmh). Pretty impressive. |
re: Life of one YETI - Tom Frajer's Axial Yeti build log Oops. Told ya! What a mess. :p As for your broken rod ends, you need the longer "Currie length" upper links with that axle. Then you can use the shorter "revo" rod ends which are much stronger. Had the same issue when I switched my rear truss. Oh, and if youre thinking of going 3s... Do it! Just drop a couple teeth on the pinion. Then start breaking even MORE parts. :lol: |
re: Life of one YETI - Tom Frajer's Axial Yeti build log 20 minutes hard bashig in the dusty environement. Finished with broken rod end on servo horn link. Rear stock bevel gear stripped and probably bent currie axle shaft. Oooops :) Those plastic rod ends are really weak spots in whole setup. Hope RPM rod ends will hold up better. UPDATE: bevel gear and pinion is OK. Cause of the rear drive malfunction is unknown! I taken it apart, cleaned and everything seems working. http://uploads.tapatalk-cdn.com/2016...7fe47d98c7.jpg http://uploads.tapatalk-cdn.com/2016...6f4be57a7f.jpg http://uploads.tapatalk-cdn.com/2016...db474dde1d.jpg http://uploads.tapatalk-cdn.com/2016...b948ec7ab2.jpg http://uploads.tapatalk-cdn.com/2016...bbb737be88.jpg http://uploads.tapatalk-cdn.com/2016...526682d0d3.jpg http://uploads.tapatalk-cdn.com/2016...207078c0c8.jpg http://uploads.tapatalk-cdn.com/2016...257eae13b7.jpg |
Re: Life of one YETI - Tom Frajer's Axial Yeti build log Breaking apart rear end to investigate and to swap to heavy duty gears... This is what left from silicone grease [emoji13] This grease is too thin and gets runny under the heavy load. Next time I will try only little bit of very thick teflon grease (another experiment). http://uploads.tapatalk-cdn.com/2016...dceeb17738.jpg First signs of use on the Currie axle [emoji2] It is amazing how rocks and small particles are accelerated by front wheels brushing surface of the rear axle. This is POWER. On 2S LiPo! http://uploads.tapatalk-cdn.com/2016...0b1fdfd3a1.jpg Yeah Racing bearings. Not good. Did not stayed the abuse. Tried to rotate them and all I heard was cracking of the sand. I will buy Fast Eddy bearings... http://uploads.tapatalk-cdn.com/2016...2351e8b843.jpg Wohooo, Vanquish Currie axle shafts bent - no jumping. I did not expected this at all! Will ask for replacement and also buy another set to have some spares. I will try to straighten these up and we will see... http://uploads.tapatalk-cdn.com/2016...f57c12ffcb.jpg Stock RTR gears. There is some wear, but they are not stripped as I thought. Pretty impressive. Now that is the question - why the hell rear axle was not turning under the throttle? I thought gears were stripped, but apparently that was not the case. I was running on front 2WD for awhile. Rear center drive line (MIP) was spinning under throttle and set screw was fastened to pinion. Maybe it was hexes loosening and sliping out of pins? http://uploads.tapatalk-cdn.com/2016...7be282543c.jpg The GASKET! Now I see it, hehe [emoji13] I was unable to install Incision locker because of it! http://uploads.tapatalk-cdn.com/2016...d5f665ef50.jpg Rear is taken apart... http://uploads.tapatalk-cdn.com/2016...02d8458afd.jpg New heavy duty bevel gears. On the left is Boom racing, on the right is Axial racing. Will instal Axial to the rear as it looks more solid and is overdriven. http://uploads.tapatalk-cdn.com/2016...4afd1f38a9.jpg And now the front... http://uploads.tapatalk-cdn.com/2016...1f4ec66aac.jpg Broken servo rod. This was GPM racing rod that I instaled on place of stock axial part. http://uploads.tapatalk-cdn.com/2016...f990517e18.jpg Going back to stock for now and hope it will hold up... http://uploads.tapatalk-cdn.com/2016...dba96893d8.jpg Finished for today. I will put everything back together later. Hope I will be able to straighten Currie axle shafts. Any advice on that? Vinch and rubber hammer? http://uploads.tapatalk-cdn.com/2016...e4d659cc9c.jpg |
Re: Life of one YETI - Tom Frajer's Axial Yeti build log I had the stock rod ends pull out on the steering servo link the first day I had mine out. The kit had some longer rod ends so I put those on and they are holding up well. Just an FYI if you encounter the same problem with your servo link. |
