pscartozzi,
Your SU-100 looks awesome, and I'm jealous as it is moving along at a clip much faster than mine. Unfortunately my SU-85 has taken a backseat to some other more pressing and time sensative (non RC) projects.

The Trumpeter static kits are amazing with incredible detail. You do need to be very selective in what you use, as many of the detail parts are fragile and simply won't stand up to the abuse of running these tanks on a real battlefield.

I'm planning on keeping the lower WSN hull as well as using the more stout stock suspension parts. Then combine the back half of the WSN roadwheels and sprockets with the more detailed Trumpeter outside half as they have crisper and more refined detail. Likewise I'll be mating the Trumpeter upper hull which has much better cast metal texture and details, to the WSN lower. All of the engine louvers are operable, as well as the hatched and a multitude of detail parts. The fuel can tie downs and rear engine deck screening are photo-etched brass affairs...........very nice. You end only using about 15-20% of the Trumpeter kit, but the results are well worth it. Because they are made by the same company and share some parts most things can be crossed between the two with only a little adjusting and tweaking.

The retail on all three versions that Trumpeter puts out is about $140-150, but you can usually find them on e-bay for about $80. Which is pretty good considering they come with complete interiors, and complete engine and transmissions. It's actually kind of a shame most of those parts will go to waste. Of course the tracks are too fragile to run but look great for the "extra " track hung on the hull (come with ice cleats as well) and all of the pioneering tools are nicely done.

Ethan, the co-founder of our club DAK has already done this WSN/Trumpeter kitbash twice, once for his T-34/76, and again for his SU-122, both with great results. He and I started out as "small scale" modelers with the intent of building RC tanks that could actually run and battle (Tamiya Full Option) while being accurate and clean enough to pick up off of the battlefield and win awards on the contest table. So far so good, Ethan's T-34 took a Silver medal at the last show, right behind my Gold winning Tiger (Sorry had to toot my own horn, LOL)
