johninderby Posted June 27, 2017 Share Posted June 27, 2017 (edited) Bought a brand new boxed Axial Yeti Jr off a mate at proper mates rates. Too good a bargain to pass up. Axial's mini Yeti looks a lot like it's bigger brothers at first glance but being only 1/18th there are a lot of differences under that body. The little 380 motor is probably adequate for now but may go brushless in the future depending on how it performs. The man weakness the Jr has is the servo. Barely up to the job and tends to fail very quickly if a 2s LiPo is used. Savox servo already purchased and will be fitted immediately. The stock ESC/RX unit will be replaced with a Tekin ESC and a Flysky RX and the 1300mah NiMh battery replaced with a 2s LiPo.. Fortunately all from the spare parts box. Axial's Blurb: Chassis: Molded plastic Drive: Four wheel shaft Rear Axle: AR18 solid rear axle, two-piece design, captured pinion gear, three link rear suspension Radio: Tactic TTX200 SLT 2-channel pistol grip, steering and throttle trim and reverse, and end point adjustment Steering Servo: Tactic TSX106 high speed micro servo rated at 26.5oz/in of torque provides smooth and precise movement of the metal gear train Electronic Speed Control: Tactic RE20 2.4GHz receiver/ESC combo auto-bind with LED indicator, 2S LiPo capable with voltage cut-off, and adjustable drag brake Motor: 380 size 40 turn brush equipped Pinion Gear: 48P 15T metal Suspension: IFS (independent front suspension), floating solid 8mm rear axle with 12mm hex adapter and open diff Shocks: Oil-filled, 3mm shafts Battery: Duratrax Onyx 7.2V 1300mAh NiMH with mini connector Battery Charger: Duratrax Onyx USB NiMH Battery Tray: Length and height adjustable, accomodates 6-cell NiMH or 2S LiPos Motor Mount: Adjustable Wheels: Method Race beadlock style, black in color, 12mm hex Tires: BF Goodrich Krawler Ball Bearings: Full set of sealed ball bearings included SPECIFICATIONS Length: 11.6" (295mm) Width: 6.9" (175mm) Height: 5.0" (128mm) Wheelbase: 8.1" (206mm) Ground Clearance: 1.1" (27mm) Weight: 1.75lbs (0.80kg) RTR with included battery Body; Length: 10.5" (267mm) Width: 4.25" (108mm) UNBOXING Remove two front body clips and the shell lifts up out of the way. 380 Motor and combined ESC / Receiver 1.55" wheels and are attached with a screw rather than a nut.

.AJ. Posted June 27, 2017 Share Posted June 27, 2017 Nice, I nearly bought one last week, but the plastic drive cups put me off Quote Link to comment Share on other sites More sharing options...
sunny Posted June 27, 2017 Share Posted June 27, 2017 Someone will surely make metal ones soon if they haven't already Quote Link to comment Share on other sites More sharing options...
.AJ. Posted June 27, 2017 Share Posted June 27, 2017 Probably, not a great selling point tho Quote Link to comment Share on other sites More sharing options...
johninderby Posted June 27, 2017 Author Share Posted June 27, 2017 It's only the front inner drive cups that are plastic but they aren't plain plastic. Look more like delrin. Outer drive cups are metal. Quote Link to comment Share on other sites More sharing options...
johninderby Posted June 27, 2017 Author Share Posted June 27, 2017 (edited) GPM make a lot of metal replacement parts including front CVD shafts but keep the plastic inner drive cups. No one seems to be breaking the drive cups either. https://www.gpmparts.com/axial-racing-yeti-jr-c-1532_3722_4397.html Edited June 27, 2017 by johninderby Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 27, 2017 Author Share Posted June 27, 2017 There have been plenty of brushless conversions without causing any problems with the drive cups. Must be tougher than they look. Quote Link to comment Share on other sites More sharing options...
capri-boy Posted June 27, 2017 Share Posted June 27, 2017 One of these would sit very nicely with my other micro's... alas the high retail price means it isn't going to happen. I really need to scratch this solid rear axle itch. 1 Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 27, 2017 Author Share Posted June 27, 2017 Turnigy Nanotech 2s 2200mah LiPo is a perfect fit in the stock battery tray. Slightly bigger than the stock 1300mah NiMh. John Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 28, 2017 Author Share Posted June 28, 2017 Want to put the new ESC RX and servo in first. Judging by today's weather a submarine would be more suitable outside anyway. John 1 Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 28, 2017 Author Share Posted June 28, 2017 Has stopped raining for a bit but the new lawn needs mowing I think. Not bad considering it was bare earth two weeks ago though. John Quote Link to comment Share on other sites More sharing options...

johninderby Posted July 2, 2017 Author Share Posted July 2, 2017 Fitted the new servo and the RX and ESC. Very plasticky chassis that could do with a few alloy bits. Undo two screws and the chassis folds in half so the stock ESC and servo can be removed. Couple of screws underneath and a few on top and the ESC housing and servo can be removed. Savox 255 servo. The stock ESC housing has the servo mounting on the bottom of it. Stock ESC/RX. Small enough to be useful in something else. Stock 380 motor And yes the ESC housing does sit at a slight angle. Motor mount is adjustable so easy to fit other pinions.. Tekin FXR ESC and Acoms RX which just fit on top of the stock ESC housing. Ran out of XT60 connectors so used the stock Tamiya type for now. 3 Quote Link to comment Share on other sites More sharing options...

Gaz! Posted July 6, 2017 Share Posted July 6, 2017 I think I'll have to get one of these after the traxxas trx4 beasty thing has landed. as always, nice work john Quote Link to comment Share on other sites More sharing options...
johninderby Posted July 6, 2017 Author Share Posted July 6, 2017 (edited) Quick tun around the patio and it is very manoeuvrable indeed. Turns incredibly tightly although will roll if going too fast. Decent turn of speed as well. Certainly fast enough for the back garden.Tyres are very, very soft with more grip than expected. Initial thoughts are very, very plastic but being so light weight may hold up reasonably well. Not sure about the rear driveshaft though being plastic. Chassis is bendy but being flexible probably won't break if you run into something. Lots of upgrade parts coming out though. Think I'll get the ramp out and see how it jumps Vid to follow.

johninderby Posted July 6, 2017 Author Share Posted July 6, 2017 Quick jump test of the Yeti JR with 2s LipPo. Yes it jumps OK but needs a lot more power for proper jumps. BTW new lawn so being left long for a few weeks while it roots properly. John 1 Quote Link to comment Share on other sites More sharing options...
