Raman36 1647 Posted August 9, 2014 Before the RC10 the Scorpion and Tomahawk ruled the racing circuit. Heavily modified SRBs (which barely looked like SRB) and ORVs could never come close to catching it. Share this post Link to post Share on other sites
Grastens 2795 Posted August 9, 2014 It may depend on the race scene, though... According to this gentleman, the Frog beat the Scorpion in Germany: http://www.tamiyaclub.com/forum/index.php?showtopic=2586&p=20003 However, the Tomahawk was of course superior to both. I find it interesting that the Scorpion has a similar chassis configuration to the Tamiya Striker. The Scorpion's strength is literally derived from the two aluminum rails beneath the lower body, but the lower radio box and upper bodyshell have me thinking of the ill-fated beginner's car. So, at once they are similar and yet so very dissimilar - the Scorpion has the superior gearbox, front suspension, rear suspension (likely, even though they are actually the same angled semi-trailing arm configuration), tuning options, balancing... We now know why it was re-released first! Share this post Link to post Share on other sites
Raman36 1647 Posted August 9, 2014 I can't speak to racing in Germany.. But here in the states the Scorpion dominated.. ORVs did not come close. In fact initially the Scorpions did well against RC10s because they were still lighter. Hence the Swiss cheese gold pan chassisLater there was an attrition of drivers to RC10, due to its superior tune ability. Share this post Link to post Share on other sites

Mokei Kagaku 2706 Posted August 11, 2014 How do you like the real one? The arrangement with the engine in front of the gearbox, A-arm suspension and (rear) inboard brakes surely must have been pretty unique for a Porsche/VW-powered buggy at that time!

Mokei Kagaku 2706 Posted August 11, 2014 Bob Rodine's UMP buggy has been discussed in many 1:1- and RC-forums over the years, including here at TC, so you guys may know these hi-res scans I just stumbled over at race-dezert.com, but I thought I might just aswell share anyway. I deeply apologise if this is just a repeat for you all. https://scontent-a-cdg.xx.fbcdn.net/hphotos-xpa1/t31.0-8/10542416_10152227071652407_3265700439167394536_o.jpg https://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-xfp1/t31.0-8/10549887_10152227071602407_6253485005244586308_o.jpg https://scontent-b-cdg.xx.fbcdn.net/hphotos-xpf1/t31.0-8/10550050_10152227071637407_8006926709308248554_o.jpg https://scontent-b-cdg.xx.fbcdn.net/hphotos-xap1/t31.0-8/10496105_10152227071617407_2083264624066625198_o.jpg https://scontent-a-cdg.xx.fbcdn.net/hphotos-xpf1/t31.0-8/10403762_10152227071597407_984638622311766939_o.jpg https://scontent-b-cdg.xx.fbcdn.net/hphotos-xpa1/t31.0-8/10483826_10152227071607407_2004698023935483683_o.jpg 2 Share this post Link to post Share on other sites
Mokei Kagaku 2706 Posted August 11, 2014 Actually, nerf bars might be a cool hop-up. CRP made nerf bars for the Scorpion, but appropriate for that time, more purposeful than realistic. Still more realistic than the Kydex nerf wings they also made for it! Share this post Link to post Share on other sites
scootmike 36 Posted August 11, 2014 CRP also had a single bar nerf set, as well as JG Mfg. I have both sets of nerf bars from CRP, and the full cage as seen in the pics, I've not been able to convince myself to drill holes in the cage to mount the 3 point nerfs. Also have 1 of the JG nerfs, the other was missing from the pkg, I don't think it was ever in there, the pkg had no holes or damage, just missing a bar. Plan to make the matching bar out of aluminum stock, made a rolling bender. Need to finish this one someday, the re re kinda took the thrill out of it. http://www.tamiyaclub.com/pictureframe.asp?t=n&id=img985_25032014222904_1.jpg 1 Share this post Link to post Share on other sites

Penzes 7 Posted August 18, 2014 I recently ordered a Scorpion 2014 to build it. I have no recent experience in the RC world and I'm looking for an suitable motor for this baby. I was thinking on the Novak 13.5T Vulcan with the stock controller for this engine. Would it be OK for the Scorpion? Share this post Link to post Share on other sites

mrmtodd 2 Posted August 20, 2014 I'm sure some of you are familiar with Time Tunnel, and the awesome work TanaTwo puts into his clean builds. I love the pics in the link below...gorgeous re-re scorpions out on the track! http://blogs.yahoo.co.jp/tanatwo1970/69200455.html I did a quick google on tqtoshi that is mentioned on tanatwo's blog, and this page below popped up... Erm, make sure your wife or significant other has left the room because there is VIDEO! 2nd vid and the HX-A500 vid (scroll way down the page) are sweet. The 4wd Scorpion Beetle makes an appearance at 4:00 min in the HX-A500 vid. http://sky.ap.teacup.com/applet/tqtoshi/201408/archive Here's some translation of Katakana that may help some google searches スコーピオン = Scorpion トマホーク = Tomahawk スコーピオンミーティング = Scorpion Meeting Jコンのタイヤ = J-concepts tire ラジコン = Raji Con or Radio Control モーター = Motor タイムトンネル = TimeTunnel Cheers, -Matt 1 Share this post Link to post Share on other sites

Or does it come with it ?. ( i didn't get one of the scorpion's ) . But i did get two of these motors .. The re re does not come with a motor, it is listed in the hop ups for the Scorp. I have 1 coming along with the HG shocks, Kyosho sure knew how to get people excited by offering the hop ups. I check everyday for them, they have my interest (HOP UP JUNKY) Shame Tamiya didn't do something similiar with the SS BC, they could have sold a lot of them. 1 Share this post Link to post Share on other sites

pl212 5 Posted August 30, 2014 What's odd to me is exactly how the doggone binding is caused, or fixed, by the various screws holding the metal rods in place. I have been able to fix the problems by following the advice above (pull the arms outwards, tighten the inner screw first) but am trying to understand if the problem is originally caused by: 1) The rod holders turning due to the screws being tightened underneath, or 2) The rod holders being pulled too far down due to the same. Put another way, what exactly does pulling the arms outwards ensure when tightening the screws? Share this post Link to post Share on other sites

Hi they could have used a hair shorter dog bones or cut into the drive cups a little deeper and it would work...pulling the arms out like shown in my photo makes the rear toe in and makes the length longer from drive cup to drive cup and also a little rear toe is a good thing it will make the buggy run better this way.

tillmon 2 Posted August 31, 2014 I've read somewhere that the problem can also be fixed by using the ball diff of the RB5/RB6 instead of the gear diff, the outdrives are supposed to be a little deeper… Share this post Link to post Share on other sites

bjorklo 1620 Posted August 31, 2014 As we all know tamiya club is not a good influence when it comes to sticking to budgets, so i just ordered a scorpion. Not sure if i will build it or keep it NIB, but after seeing some pictures of it on the beach, i might just have to build it :-) 1 Share this post Link to post Share on other sites
Penzes 7 Posted August 31, 2014 You know, the best way to satisfy your self is buy two kits, one for the beach and one for NIB/shelf-queen or in the worst case as a spare part stock. 1 Share this post Link to post Share on other sites
