Thanks!

Hi there! First of all, I’m going to assume you’re using the correct pinion spur combo. The kit includes two for different gear ratios. Assuming that’s ok the next thing I would look at is the shaft that the spur mounts on to. Of the five buggies I’ve built with that gearbox one had a mesh that seemed tight at certain spots as it rotated. The solution I found was to simply undo the screw holding that shaft in place and re tighten it 180° from its initial position. (It’s supposed to be setup so the body pin hole is horizontal). That seemed to solve the problem. Don’t forget the thread lock too. A final possibility is the motor plate has a slight bend in it. Unlikely, but possible. You could also try a different brand of pinion. If the backlash isn’t too far off ideal, I might be tempted to run it. The gears should bed in after a little use. 👍 Hope that helps!

@ thanks so much! I’ll give the shaft spin a try. I appreciate your help! The GO TO Kyosho legends legend 👌

Will try! 👍 Night races at Carnosa are pretty hectic, so not a lot of time to film in the pit.

Thank you! When I began making videos I never imagined this channel would have grown to reach 4,000 subscribers. The amount of support I have received has been truly heartening.

Wow, thank you!! 😊 I had no idea this video would prove to be so useful to so many. As things have moved on and Kyosho continue to add new machines to the Legendary Series, I plan to revisit this topic and produce an updated version. But first I need to get around to building the newer machines including the two '87 Worlds specials and the Optima Pro.

Thank you!! It is heartening to know that my video is bringing a smile to so many viewers faces. ☺️

Thanks for the kind words.☺️ It must have been wonderful to see Masami back in the day! The atmosphere at the track would surely have been amazing. I would have liked to go myself, but Romsey was quite a way from where I grew up in Derby. Eleven year old me probably even considered riding his BMX there. 😂 I'm fortunate that almost 40 years later, not only did I get to meet the Legend, I was able to run alongside him on the track. ☺️

@ A long time ago now. Inspired me to race myself. I still have the program from the day.

Thanks 👍

Thank you for the support! 😊 I did better than I hoped in the races. Your Tomahawk looked great out on the track. Unfortunately my mirrorless camera was having focusing problems, so a lot of the footage was unusable! 😥 I will definitely be attending GFCC 2025. See you then! 😊

Yep, surely! Can’t wait!

Glad you enjoy it! 😊

Thank you for the all the support you've given to me. It is very much appreciated. 😊

Thank you! I had intended to do a more thorough pit walk and speak with some other participants. But just never got the time!

@ sure I understand as it’s busy at a Race meeting especially running 2 classes, just cool to see the Japanese cars/people and builds Keep up the great work 👍🏻🏁

Oh yes! And that wasn't even all of them. Quite a few remained on the pit tables during this shoot.

Yeah, mine seems to be particularly bad. It's all in the setup and technique, both of which I just haven't quite nailed down...yet. Overall, the 870c drove better than my last outing with it. The EXO Design conversion kit and big bore dampers helping tremendously. Undoubtedly my biggest mistake was gearing. I should have dropped a couple of teeth on the pinion to give me the punch needed to clear that double consistently. Nevertheless, the 870c is a wonderful machine. I still can't get over how smooth and quiet it is on the track. Makes every other buggy (except the BBX) seem almost agricultural in comparison. 🤩

Thank you! I had a superb time. I will be returning again next year for sure. 👍

Yes! It was quite the turn out. Having seven classes in all made for a wide variety of machines. Regretfully I didn't have the time to film more of them in detail or speak with the owners.

Thank you! It is a shame that so many RC's will spend their time on the shelf not being used. But people are free to enjoy the hobby however they wish. I'm not really one for shelf queens, but I'd be lying if I said I wouldn't want to fill a hobby room with a collection of pristine buggies...in addition to my runners, of course! 😁

@@KaiCityRC Agreed, they certainly are works of art. The ten year old in me is confused by shelf queens but the 51 year old is selecting which order to line the vintage buggies up in :)

The reason I ask is specifically because I want to design and test new rear suspension ideas on RC first before going full scale, and people on the RC cars subreddit suggested I use the Turbo Scorpion as a platform since the pickup points on the rear trailing arms are similar to what I want to install... TBH I'm still not convinced and think I should either go with a Traxxas chassis or a custom chassis, but with the latter, I have no idea how I'd do the front, TBH.

The double wishbone setup on the Ultima is much better to work with than the trailing arms of the Scorpion chassis. This is especially true on high grip surfaces. I've not run the Scorpion chassis buggies with anything quicker than a 17.5 brushless setup, so can't comment on how well they'd handle higher power setups. Regardless the Ultima would be my choice. The Scorpions have a wonderful old school appeal, but they'd don't really stand up to modern buggies. If you're just looking for some kind of test rig for a full scale development, might it be best to choose an RC buggy with a similar front suspension design to that of the full sized vehicle? I have zero experience with Traxxas, so can't say if it would be a more suitable route.

@@KaiCityRC ​ @KaiCityRC All modern buggies currently use what full-scale offroad vehicles use on the front; DWB. Though to be frank, full-scale versions are better as it seems that RC cars lack _actual_ geometry in order to give them usable camber gain characteristics. Having equal-length arms that are perfectly parallel to each other is seriously bad for cornering, especially on the rear where the caster angle can't make up for it because the rear wheels don't steer and don't have caster. The reason I asked about Traxxas is that they're seemingly cheap with plentiful aftermarket upgrade parts for the little things and other people seem to mod them what with the small plethora of mid-motor bandit builds, custom shock towers and bulkheads etc. out there.

I went with Kyosho weighted silicone diff gear grease.

@ I think I need to try that…oil doesn’t seem to want to stay inside

The Instructions for the Legendary Series buggies aren't bad, they're just not as good (IMHO) as Tamiya (which are very good and aimed at complete beginners). The Kyosho manuals don't have much in the way of explanations, more a series of diagrams. There are a few (minor) errors here and there, but nothing major. And newer batches of kits seem to have revised manuals. The Tomahawk is quite a straightforward build and if you're unsure, help is just a few clicks away. There are a plethora of build videos on here too.

It's quite a mix. G Force Genova is the most popular, followed by the Kyosho Dirt Master. There are a few DT-03's and Yokomo B-MAX2. And then a Kyosho Scorpion, Vintage RC10 and my PR Racing S1 RM. In earlier rounds there were quite a few BBX running too.

@KaiCityRC we're good at spotting dt03s because they look like canoes underneath, just getting into this hobby and we're building one of those next having just completed a plasma edge 2 in time for the UK winter gloom

It was! 😁

The vintage RC10 isn’t mine. I ran the PR Racing. S1 RM. The RC10 ran really well. It came 1st in the previous round and took 2nd in this. 👍 Not bad for a nigh on 40 year old machine. 👍

Despite its lack of performance, the Grasshopper more than makes up for it with character. It’s hard to think of a more fun RC for the price. It remains very popular even to this day. 👍

Thanks! 👍

Agreed. I suppose AE could argue that since the kit didn’t originally come with bearings, they don’t have to/shouldn’t include them in the re-release. But if so, then we should get the original, well written and very detailed manual too! 😁

I'm currently away from home, so unable to check. But pinion size will depend on some many factors - where you run, surface type, motor, battery, runt times etc. I'd start with the kit supplied one (I think it's around 24T or so) and go from there.

@ thank you very much!

Thanks!

Agree totally! I'm not one for shelf queens and try to run everything I have. I really want to use the RC10 for vintage racing, but spares are holding me back!

Thanks!

Glad it was useful Thanks! 😊

Thank! I'm glad the video was helpful. I love my Javelin. One of THE best looking buggies for sure. 👍

If memory serves I used the kit supplied washers as is, only replacing the "flanged metal" as kyosho call it with the optional bearing. But you could use any suitably sized washer. Be careful not to over tighten the screw as it will start to bind.

@KaiCityRC i must be doing something wrong because the standard washer is to large and would therefore tighten down on the outside race to. I had to get 3x5mm Shims to press only on the inners from kyosho. How did you not compress the whole bearing down solid when tightening the 3m screw down? Been trying to understand this because I have the 6x3x 2.5 correct bearings

@@rogergale3297 I checked and can confirm I'm using the supplied washer. Are you using the correct flanged bearing (BRG007F) and it is inserted with the flange at the top? Also it is really important not to tighten the screw down too far. You're just removing the play between the drag link and the bell cranks, nothing more. If you tighten too far the whole thing will bind. Hope that helps!

@KaiCityRC hi there. I do appreciate your reply...thankyou for your theory on this. Perhaps that's like you say...maybe I shouldn't tighten it right down. The way I've done it now so that I do tighten it right down is to place a couple of Shims underneath that are 0.1mm thick but crucially tiny 3x5mm so the inner bearing race underneath sits on these. It works well but I was unaware that the screw originally shouldn't be tightened fully. Much appreciated, and great channel by the way. The flange is at the top and the bearings are correct number. All my other cars have never had this design from schumacher.

Thank you for the sub. I'm glad that my video helped brighten your day. ☺️

That line ALWAYS had me in stitches with laughter! 😂

@@KaiCityRC Me too he delivers it well :D

Wow, thank you for the kind words! ☺️ I got lucky with the timing of this video and arrived at the park when conditions were just right. 😊

Thank you! 😊

Thank you! ☺️ I must admit I am wondering why it took me so long to finally add this iconic buggy to the collection.

Thank you! ☺️
