For airbrushing you can use either one for your Tamiya acrylics. The lacquer thinner was developed later primarily to make their acrylics spray more like lacquers. It will also help gloss acrylics dry somewhat faster. If you ever decant Tamiya spray cans for use in the airbrush, use the lacquer thinner to thin it a bit more.
Nice job, I've built 4 of those rotten Fujimi short tail F1's including the LM...seriously flawed kits, but looks like I made the right choice building them since it seems Aoshima gave up after the odd longtail they did.
That was Academy, who are owned by the same folks as Italeri, I believe. The kits aren't knockoffs, they're just marketed to the Korean market as generic to get around Ferrari licensing which is a monster pain in the backside for just about any company outside of Tamiya and Fujimi. Notice how Revell doesn't have a single Ferrari anymore?
No tooling ended up in China, they're simply poor knockoff copies of a Tamiya original. They are lousy kits by comparison, and $10 isn't a deal, unless you like ragged mold lines, poorly printed stickers instead of metal transfers, etc. I've seen some of these kits up close, and having built and bought the Tamiya versions, I can tell a lousy copy from the original with ease. I can find Tamiya originals for about $15, no question of value by comparison. The closeup of the engine intake? Horrible quality! The Tamiya engines in these are magnificent, they are so well molded they practically hold themselves together w/just the pins & receivers, and surface quality is perfect. Not on that lousy copy!! There are a few Tamiya kits copied, but it's been many years ago and isn't even close to a common occurence.
That used to bug me too. Not any more; I realize the RHD models I have built never "call attention" to their driving position. I also see many Japanese-market cars at our local car shows now that the 25 year rule is in effect, allowing importation of cars never seen here before. It's pretty cool. I have no problem w/the Civic being RHD, but if you study the actual dash design, it won't be that hard to convert...if the aftermarket doesn't accommodate.
