Mansnake Posted September 16, 2015 Share Posted September 16, 2015 Was there not a motor spacer included in the kit for spacing the pinny before installing the can?? Drop of blue threadlock on the grub screw and leave to cure for 24 hours....could be the grub has lost its bite from spinning on the shaft so pop a new one in. If you have a dremmel, a small notch on the motor shaft where the grub sits will aid grip too....shouldn't really be required on a Lunchy, every little helps though Looks like iv'e sorted it. I think the original issue was caused by my attempt at some poor man's wheel inserts which I made with foam from work. I'm thinking it unbalanced the wheels which at speed probably caused enough shaking to shake the grub screw loose. Once I removed the foam from the wheels I was trying it on a nearly flat battery which obviously made it look like it was still not right. Once I recharged the battery, it now runs fine again. Thanks for all your suggestions and input........if in doubt charge the battery! Quote Link to comment Share on other sites More sharing options...

Eek, I'd planned to make some like that for my clod, after struggling to find any to buy. I guess I'll still go ahead as I've bought the foam, but I'll be watchful for this.

I didn't fill the wheels fully and they were probably filled with different amounts as I didn't measure them so would have been unbalanced. it was my first run out on my 2s so didn't think about it. I think i'll buy some proper ones next time Quote Link to comment Share on other sites More sharing options...
TurboFurball Posted October 21, 2015 Share Posted October 21, 2015 Welp, I've been generously given a broken Lunchbox as an early xmas pressie - it's payday on Friday so will be ordering all the needed bits then After a year of driving my friend's one it'll be very cool to have my own ... I'm a bit excited! I'll report back with photos in a couple of weeks once it's all together ... Quote Link to comment Share on other sites More sharing options...
Nismo75 Posted October 22, 2015 Share Posted October 22, 2015 The last couple of times I've taken my Lunchbox out the steering is always failing. After a couple of occasions tightening the servo saver the screw is just constantly turning and not tightening up. Any recommendations for a new servo saver? Is the tamiya one any good? Cheers Brian Quote Link to comment Share on other sites More sharing options...
AndySeven Posted October 22, 2015 Share Posted October 22, 2015 Well for starters I don't like the Tamiya servo saver and use the KIMBROUGH servo savers, also make sure you use the correct horn for your servo. Quote Link to comment Share on other sites More sharing options...
TurboFurball Posted October 22, 2015 Share Posted October 22, 2015 I'm going with a Turnigy 17kg servo (metal splines are worthwhile) and an Integy alloy servo saver ... that will probably mean I bend steering rods, but I figure that's a better sacrificial part than the servo saver Quote Link to comment Share on other sites More sharing options...
Popular Post StrokerBoy Posted November 4, 2015 Popular Post Share Posted November 4, 2015 So, 26 years after I first built a Pumpkin (which I've still got), I've finally got a Lunchbox. Well, it's a Unimog CW-01 kit, but for now it's wearing a Lunchbox shell. I built this 'Fuzzbox' yesterday. Bearings all round, SportTuned motor, Fastrak oil-damped shocks and ProLine tyre foams. 12 LED's plus the roof bar. 5th shock and FX-10 mods still to come, plus remote light switching via Ch.3. 9 Quote Link to comment Share on other sites More sharing options...

TurboFurball Posted November 18, 2015 Share Posted November 18, 2015 I appear to have overpowered my Lunchbox - the combination of a 2s lipo and a 15 turn motor gives nice things like being able to pull a wheelie while already rolling at a good speed, but it's a bit more than the package feels comfortable with. I'm going to swap in a fresh 25 turn sport tuned motor from my parts bin instead, to try and ease it up a bit. Which begs the question, where do you think the sweet spot is?

PraetoR Posted November 18, 2015 Share Posted November 18, 2015 I found that with a lipo -even with a higher turn motor- the increased "kick" of power and the lack of weight in the battery compartment makes the car just a bit too much of a handful. With the ni-mh, you had a lot more weight very low-down, which is now all but gone. I plan on putting some lead wheel weights low down on/in the chassis, to try and bring-back some of that lower COG. Might be with pursuing, yourself? 1 Quote Link to comment Share on other sites More sharing options...

caleebra Posted January 11, 2016 Share Posted January 11, 2016 New member of the LB club here I got a standard yellow with ESC for my birthday, bit of retro fun for this big kid. I remember this was on my Santa list for years in the late 80s early 90s! I see the LB as a fun and quick access alternative to my Savage X4.6 - so a bit of garden bashing. Looking forward to getting stuck into the build - have already ordered up an HPI SF-10 servo (same as Savvy throttle/brake) and in the interest of spares/compatibility I hope to run the TF40/RF40 radio kit. Anyone else got this set up? Do I need a BEC somewhere? Quote Link to comment Share on other sites More sharing options...
Noj Posted January 11, 2016 Share Posted January 11, 2016 Shouldn't require an external BEC for an LB running that servo.... What ESC and motor is fitted, stock Tamiya?? Bearings installed yet? Fifth shock mod done?? Oh, and welcome Quote Link to comment Share on other sites More sharing options...
caleebra Posted January 12, 2016 Share Posted January 12, 2016 Nothing is installed yet it's all in the box! But bearing kit is on order! 5th shock etc can wait til I experience the stock comedy! Need to pick up some glue and paint. The reason for my BEC question was an assumption that my kit contained a TEU101BK but it's actually a TBLE02S which has a 6V 1.5A receiver output, so good to go...

mond Posted January 13, 2016 Share Posted January 13, 2016 I've entered the club and bought a lunchbox, the version with the ESC and Motor. Been reading up on what I should be doing with it, so also will order The aluminium body mounts, rubber sealed bearing kit and a pair of Tamiya 50520 CVA Short Shock Unit Set II kits (I wanted to keep it as Tamiya as possible!). Will do the chassis support mod with some spare turnbuckles but will look into that 5th shock. Couple of questions - I want to replace the ESC and Motor with a waterproof, ideally brushless system which includes a BEC. Don't want to go bonkers but what is a good set up to use? Is there a stainless steel hex screw kit available? Quote Link to comment Share on other sites More sharing options...
caleebra Posted January 20, 2016 Share Posted January 20, 2016 Finished my LB chassis and electrics, all working nicely. Now for the stressful part... painting the body! Are there any cheap lexan shells out there that will fit for bashing duties? Would be a shame to destroy the fantastically detailed styrene original.

johninderby Posted January 20, 2016 Share Posted January 20, 2016 (edited) Parma does a lexan Lunchbox body but seems to be out of stock everywhere in the UK at the minute. Some US dealers are showing as in stock though. John Edited January 20, 2016 by johninderby Quote Link to comment Share on other sites More sharing options...
Noj Posted January 20, 2016 Share Posted January 20, 2016 Not come across a specific screw kit for the LB....all be standard M3 lengths. 15t brushed is as crazy as mine gets, really doesn't need a BL set up IMO.... If you want cheap, drop in a Trackstar set up and pray it's a good one Quote Link to comment Share on other sites More sharing options...

caleebra Posted January 27, 2016 Share Posted January 27, 2016 I am going to paint my body this week.. stressful!! At first I thought I'd just wap a bit of paint on and get outside and bash it... but I find myself getting a bit fussy over the wee thing - the Tamiya body detailing is a thing of beauty.
