Default Thunder tiger mirage - anyone have one? I need motor/mounts/clutch dimensions.

As the title states, I need an engine, engine mounts, and a clutch.

The problem is I don't have the old stuff to measure. Are the .21 (or larger - I've seen some .28 engines from horizon) engines still relatively standard as far as case/mounting hole dimensions? I know the mounts aren't too critical as long as there's enough adjustment to get proper gear mesh.

Also, anyone have an instruction manual they could scan/point me towards? Or at the very least the engine requirements page(s)?

Any help here would be greatly appreciated.

The mounting holes on the engine are standard(big block) where you may run into issues is finding mounts that line up with the holes in the chassis. I have countless engines, and a sizeable tub of mounts. Give me some measurements of the chassis mounting holes, centered front to back and centered side to side, and I can tell you if I personally have mounts, or tell you which mount you can buy that fits. I believe it came with a 14t clutch bell. A manual can be found on manualslib.

Here's the dimensions for the motor mounting holes on the mirage. (Apologies for quality, knew software install and don't have the presets punched in yet.)

Looks like the TT EB4 s1/2 mounts are the same as well, but different part numberss. Does your motor have the pull start? That's something I need as well.

How much are you looking to get for the parts?

Sounds more than reasonable! What condition are the engines in? I know they can be rebuilt, but haven't seen any parts to actually do so. This would be a basher but I'd still like to get something that has decent life remaining.

Crap, forgot to ask, these are rear exhaust correct? I'm also in the market for a manifold & tuned pipe if you happen to have those laying around as well.

It's in really good condition, if average lifespan was 10 it's no more than 4. They are rear exhaust, big block car/truck engines pretty much all are. As far as exhaust, I can throw in a basic setup(2-piece pipe and manifold with coupler and spring) for another $10.

Well sheet!!
I guess I should be asking about what you don't have!! Happen to have a radio box cover, fuel tank, and wing? Oh, and screws/washers for motor mount to chassis (I've found 3 in my parts box)? Also found the large poster sized assembly diagram for the mirage. Only documentation I have left.

Plus whatever else you may have? Apologies for nickle-n-dimeing on the parts requests, I had the chassis handy but just went through all of my part bins.

I see some new EB4 fuel tanks but they look to use a lower mounting position. If the hole pattern is the same I'd just need shorter standoffs. The EB4's look almost identical to the mirage, but I know they made a few upgrades just from looking at the parts. Question is whether the chassis & all the hole patterns line up. I suppose I could drill & countersink a couple holes though.

It doesn't look like it, but did TT ever offer a shaft start on their pro21r engines? I fell in love with E-Start on my Traxxas 4-tec so that's something I've been looking at. But your deal for what amounts to a drop-in solution seems pretty good. I might be able machine some flats on the pull start shaft though.

Don't know what you're running, but would you be interested in swapping a brand new, unpainted, still has the overspray film, mirage body for a beat up one? (I such at painting)

Ok, last request. Could you post a few pics of the items discussed so far?

I was actually planning to bring up the shaft starting option, the 21r equipped associated mgt came with the dual start system for pull or shaft starting. I was going to ask which starter you preferred, pull, roto, or combo pull/shaft. I planned on keeping the aftermarket cooling heads, letting you choose the red(stock mgt) or purple(stock Schumacher Menace- this one is shaped like the original mirage cooling head)
wing shouldn't be a problem, but radio box cover I won't have. Although I have a few complete radio boxes and one might fit. Same with fuel tank, I'll have to get a look at the original to see which one of these will fit best on the chassis.

WOW!!!!!! 😮
You've got a regular "pick-a-part" for RC cars there!!
That associated with the combo start looks really clean. Head matters not to me. I suppose stock looking would be best, but even one from the bottom of the pile would be fine. It'll probably get some road rash anyway. I'm not building a show piece, I intend to beat on this thing. It ceased racing the first time my brother plowed it into a curb. But it's so much more durable than my Traxxas stuff. I just put it into a vise & bent the chassis back, same with the front dog bones. I look at the 4-tec funny and something breaks lol.



Here's what I have left of my Mirage. You can barely see the standoffs for the fuel tank. About 4 inches apart center to center. I can take other measurements as well.


Here's the body I have. I did most of the trimming but never got further than that. Small hole started in the windshield. So if you'd rather hoard a \"fresh" body it's up for trade. Otherwise I'll just hit it with a two tone from spray cans. I was never good at painting bodies.

I don't have any shaft start vehicles, would I be able to just buy the correct shaft & use a drill? Really don't want to spend $80 for a starter. Plus those are tougher to find with electrics killing off nitro.

Oh, and did associated use thunder tiger engines a lot? TT used to be huge in the nitro market, now they've all but disappeared. I see the motor mounts on their site but it scares me to death just thinking about ordering something from them. If you want a copy of that large poster with the exploded views I'm still working on stitching it together & cleaning it up. Should be a gem when I finish it.

Associated mgt


Thunder tiger mta4
They were/are sister brands, as you can see the associated mgt and the thunder tiger mta4 are the same vehicle. The pro 21r and pro 28 engines come with either the (ae) or (tt) logo, the radios and servos are the same with the thunder tiger ones branded "ace" instead of associated. The only difference with the engines are the logos and the color of the heads(the thunder tiger mta4 came with a red head and the associated mgt came with a blue head(21) or black head(28)
A drill works fine, as long as it's modern and preferably lipo powered. An old 12 volt job won't spin fast enough. I make my shafts out of long L-shaped 6mm ball end hex keys($1.50 on ebay vs. $10 for a replacement starting shaft) and I just cut the ends off.

Wow those things are identical! Do you remember when they became sister brands? I used to race RC10's competitively when they were still using aluminum tub chassis. During that time Associated came out with the game changing RC10 GT, which basically started the 1/10th nitro trophy truck class. Shortly thereafter racing just became too expensive for me/my family, so I picked up the Mirage. At the time it was a competitive option since the track I ran at had a class with an engine rule which eliminated the need to spend a fortune on something like Nova's just to think about being competitive. I raced the Mirage here & there but I got it b/c it was a tank.

Damn air filter came off and it pulled 2 grains of sand in which destroyed the piston/sleeve & sized the motor. Otherwise I'd still be running it.

This sounds perfect. Exactly what I was planning to do. I'm a mechatronics engineer so I was also thinking of making a starting box/shaft drive combo out of a lipo, spare heli motor, esc, and some creative electronics & a spare heli main gear. That would give me 0-3k RPM out of the 0-30k RPM from the motor & ton of torque. But that's another project so I'll use the drill in the meantime.

So it looks like we're at a shaft/pull motor w/mirage mounts (or something that would work), whatever head you want to put on it(I really don't care so whichever one you want the least is fine), clutch & 14t bell, whatever you want to include for a manifold & pipe, & hopefully a gas tank (4" center to center with the holes on a slight angle towards the front center of the car when the tank is squared up in the car is the most important dimension & I can measure the offset of the holes to nail the dimensions down if needed, with the height of the holes not being a big deal as I can just make new standoffs), a wing, and finally, a body if you'd like to trade for my unpainted copy, for ~$90 plus what you want for the fuek tank/wing.

And take your time digging around, just keep chatting I really enjoy talking about this stuff. I've been running my old Traxxas nitro 4tec around but handling sucks & I've been trying to get the "pro" ball diffs adjusted to help it out but i just plowed it into a curb at ~40+ MPH. Bent the chassis slightly but destroyed the differential carrier which is NLA from Traxxas. I might just sell it after rebuilding it with the parts floating around the net. It's un-raceable even with all the hop-ups, the 2-speed sucks & just getting it to run in a straight line under power & braking has become too much of a hassle. Or maybe I'll turn it into a race project when I have access to a machine shop.

What are the diffs like on the "newer" nitro cars? The Mirage has a straight planetary setup but everything I see now is running cross pins and bevel gears. Are there any ramps on the case/pins for torque vectoring or are they just a different design that are still tuned completely with different weight oil/grease? I see fiorini torsen type diffs that need rebuilding constantly for $200 a pop & that just seems completely insane!

Thunder Tiger EK4-S2

I enjoy talking rc shop as well, it's not like my old lady wants to hear about all the different nitro engines made by SH. And truth be told I also enjoy showing off some of my collection to someone who appreciates vintage(90s-00s) nitro RCs. I have been collecting for quite some time and I'm very proud of it. Here are some hard to find new in box vehicles:
The Cen GST is more modern, there might even be a few still hanging around in hobby shops. The Cen Mitsubishi Pajero is a bit older, I think early 2000s. The megatech dark thunder is easily in my top 5 favorites. The absolute best looking rtr top fuel dragster sold. Then we come to something quite rare nib, the EK4-S2 by our friends at Thunder Tiger. A very unique vehicle powered by the largest engine(.70/11.5cc) ever put in an rtr car/truck.
I've had a few 4tecs, and as much as I don't like them they sell like hotcakes. I've always got rs4s and nitro tc3s for sale, but the 4tecs come and go. I understand that Traxxas has superior local parts availability/brand recognition, and I too like tearing ass in a straight line, but when you actually want to turn laps the rs4 is better and the tc3 puts it to shame. Differentials are an aspect that I haven't explored beyond the superficial. I tune mine in the generally recommended range, but plan on doing some experimenting soon. I have been a "basher" since I was 10 and got my red arrow from radio shack, but have only been racing on a track for about a year. I have many hours thrashing savage/tmaxxes under my belt, but the dark art of turning fast laps is still new to me. I learned that you need to spend money on your servos, and I have a fair grasp of tire selection and shock tuning. Differentials will come in time. I can say that from what I've read the torsens do work well and I believe the losi "smart" diff is similar.
