Yonez 180 Posted April 18, 2015 A friend recently got his re-re Boomerang built and is bashing around with it. While building cars is my passion in this hobby, it would be great to get out and bash with friends now and then. I'm not keen to tap into my stock of vintage shelf queens for bashing, and while I have some modern buggies, they're too far ahead spec-wise of the Boomerang. And I think I need to build a car specifically for bashing for it not to end up on the shelf itself. My friend has ball-raced his Boomer and put in a torque tuned motor. Apart from that it's stock. I'm thinking I'll run a silvercan or torque tuned as well. It would be most fun if the car is similarly matched in other areas. I think I can convince him to modernise his tires if needed. So, any recommendations? Share this post Link to post Share on other sites
XV Pilot 1936 Posted April 18, 2015 How about a TL-01B? With its shaft drive and plethora of gears, drivetrain friction would be comparable. Weight is also similar. Share this post Link to post Share on other sites
taliesin 260 Posted April 18, 2015 Maybe a Hotshot II or Super Shot to keep it relatively competitive. I think the next gen 4WD buggies like the Fire Dragon, Thundershot, etc. might run away from a Boomer and the DF-01 generation of buggies would just kill it dead. Just my opinion though, not to disrespect to the aged and venerable Boomer. PS: I realize the Hotshot series isn't modern, but ... I just don't think anything modern would be much of a fair challenge. 2 Share this post Link to post Share on other sites
Mokei Kagaku 2706 Posted April 18, 2015 I very much doubt that the drivetrain friction of the TL-01B is as bad as that of the Boomerang. Similar amount of gears and bearings yes, but certainly with much stiffer gearbox housings, generally smaller gears and much stiffer and better centered propshaft. Also, the closed diffs are much less prone to flex and partially "dislocate" under load. All factors that help keep friction loss down. On the other side, I personally think the Boomerang handles a lot better than the TL-01B, even with oilshocks and 3 degrees rear uprights fitted. I'd suggest getting a DF-02 or TT-02B, both much better designs than the TL-01B, but still not too superior to the Boomerang to allow for fun racing. That said, I really love the TL-01, just not the TL-01B, which I think is a terrible compromise of a buggy. 1 Share this post Link to post Share on other sites
Yonez 180 Posted April 18, 2015 The TL-01B is one I want for the building experience anyway. But since it is discontinued I know it will end up on the shelf. I've always wondered about it since, as you're saying, the gearbox looks as complex as the old 'shot drivetrains. The DF-02 looks interesting. The Aero Avante shell is actually somewhat reminiscent of the Avante shell. TT-02B seems to be something to investigate. Share this post Link to post Share on other sites
WillyChang 1814 Posted April 18, 2015 Get a WildOne. Original or rere, both run well on 540 or slightly hotter... they can outhandle a Boomerang if driven well; plus it's an even older design so the vanquished can't whinge unfair advantage looks great too.

Yonez 180 Posted April 18, 2015 WildOne no go; Too beautiful to drive I'm too infected with shelf-itis. I need something really ratty to be able to de-pristinize it I think I need to get two Aero-avantes; a metallic red for the shelf and a regular for the street. This is already getting hard, I've started to look at hop-ups already, but I must not get any! Share this post Link to post Share on other sites
qatmix 794 Posted April 18, 2015 TT02B buggies, cheap, handle well, parts are cheap and more than anything they are fun. For £100 you will get a car, esc and Torque tuned motor. Bargain. 2 Share this post Link to post Share on other sites

So, TT-02B or DF-02 seem to be the best options. What are the differences and main characteristics of these? I don't care much care for cab-forward buggies, but the Dual Ridge is actually kinda cool.

Backlash 481 Posted April 18, 2015 Buy an RC10, be that an original, or re-re classic or worlds.. Fantastic cars to drive, will easily out handle the Boomer, and will allow you to do some vintage racing as well if you so desire... Not being a Tamiya, you may have more tendency to drive it rather than just have it sit on a shelf.. Share this post Link to post Share on other sites
Grastens 2795 Posted April 18, 2015 But easily out-handle the Boomerang? He doesn't want to kill the other guy; he just wants to make it competitive (I think)! Getting trashed every week is a quick way to lose interest...A Dual Ridge would look cool fighting alongside a Boomerang, but a Neo Scorcher or Aero Avante would echo the classic heritage that the Boomerang represents while being based on the same chassis as the Dual Ridge. Am I correct in guessing that a DF-03 would be overkill? Share this post Link to post Share on other sites
Sandster 285 Posted April 18, 2015 How about the obvious? A Boomerang? Should be pretty evenly matched to your friends car. 2 Share this post Link to post Share on other sites
Wez-li 1790 Posted April 18, 2015 +1 A boomerang, in black Share this post Link to post Share on other sites
Yonez 180 Posted April 18, 2015 A boomerang is the obvious choice of course, but apart from the shelf tendency, I just feel it would be fun to find a modern match for it. We're just going to be bashing, so performance doesn't have to be that close. Still it's a neat idea. I've gone for the Aero Avante with some cheap noname ball bearings. Apart from that I'll run it stock. It is amazing how cheap spares are for the DF-02, looking forward to some bashing. Share this post Link to post Share on other sites

kontemax 1725 Posted April 21, 2015 I don't agree about this line. If you tune up the Boomerang it is a very fast model. Think about it, same number of gears, same module of gears. But you must to work on it a lot. Max Maybe a Hotshot II or Super Shot to keep it relatively competitive.

kontemax 1725 Posted April 21, 2015 Small gears are less efficients than bigger gears. If you have the same ratio but different gears... For example 20:10 vs 40:20 ... the bigger gears are more efficients. Max I very much doubt that the drivetrain friction of the TL-01B is as bad as that of the Boomerang.

kontemax 1725 Posted April 21, 2015 There's not a modern buggy that can match the Boomerang series that are many generations behind. The right choice to make your races interestingin my opinion is to buy a same generation model, so Boomerang, Super Sabre, Hot Shot 2, Bigwig and Super Shot (I didn't forgot to mention the Hot Shot 1 but the Boomerang suspension set up will overkill it). A second choice could be the following Thinder Shot generation but the chassis is so improoved that will overpass the Boomerang, not concerning the speed but the handling maybe.

For example 20:10 vs 40:20 ... the bigger gears are more efficients. Max I'd say that's a major oversimplification! If you mean two gears with the same physical dimensions but different amount of teeth, yes, then I'll of course agree that the gear with the highest "tooth-count" (smallest module) will be the most efficient, but only when all other factors remain unconsidered. However, what I meant in my original post was that the TL01 benefits from the smaller gears because it allows for a more compact gearbox housing. The smaller and stiffer housing means less flexing of the housing under load, allowing for more constant meshing of the gears, thus higher efficiency / less loss. Also, unless running at constant rpm, large gears will cause more loss as a result of the higher torque of inertia than small gears do. Share this post Link to post Share on other sites

kontemax 1725 Posted April 21, 2015 Sorry, I intended gears with the same module but different diameters. Double the diameter, half the rolling resistance.

kontemax 1725 Posted April 21, 2015 The Boomerang can be competitive with many newer models (concerning speed and acceleration) but obviously nor with all new models. A well tuned Boomerang is faster than a DF-01 basic chassis (Manta Ray for example) but obviously is not faster than a Top Force Evolution. For sure is fast like the Thunder Shot series. For example my Boomerang has CVD all arounds, double ball diff, hard main shaft and steel pinion gear. It could have the front one way but I was not interested in it. Anyway my Boomerang is fast, believe me. I also cutted away some weight with titanium screws and aluminum nuts. The car is fast. Max vs. So, what is the conclusion?
