The usual "Thanks very much" goes out to our friends and suppliers at Aires for providing us this marvelous exhaust nozzle; you have made quite a niche in the market, and IPMS USA is pleased to review your products!
This is an upgrade to the existing kit exhaust nozzle. As it is, there are only two parts to the Kinetic kit afterburner/reheat section; with a bit of paint and drybrush, an acceptable exhaust can be obtained.
With the Aires upgrade, not only do you get a much more detailed hot section and fairing, you get a photo etch flameholder, a detailed augmenter tube, and a super-detailed exhaust nozzle and external aerodynamic fairing petals. The only difficulty I had was attaching the exhaust nozzle assembly to the augmenter tube, but a bit of light grinding of the augmenter tube fixed that problem…it all fit well once I did that.
