# Rocksim 7

Hey guys. I'm looking forward to getting a copy of Rocksim 7, but $95 is just so steep. It's out of my reach for a while. I was wondering if any of you knew another retailer that sold the software for any less? Every few dollors helps. Thanks for your input! - strudle #### HeadHunter ##### Well-Known Member Im going to jump up on a stump here, but dont worry its a little one. If we do not support those in the industry who have, despite the insinuation that they support terrorists, gone through the effort of licensing, background searches and general harassment to provide us product for our hobby then that hobby will die. I really understand what you say about the$95.00 because I have been there done that. Nevertheless, I did manage to find the cash for my Ellis Mountain H48-8 and the other engines I bought for Mudrock11. I got my certification there. Had I bought the program before I went (have since bought it) I would not be reattaching the fins on my PML Callisto that flew my certification flight on because I would not have put an AT F62T-10 in the rocket.

Without sounding like a cheerleader for Apogee, I have learned more about rocketry in the last two weeks than I have since I started lurking around here. This group is the best in rocketry. They will provide you with any answer you need, but your own education is well worth the investment.

Alrightyhow do I get down off this stump with out breaking my neck?

Thats a good question. I believe your post would have been better suited to a thread discussing the support of these great companies, or perhaps if I asked someone to give it to me. To clarify, I was looking for a cheaper retailer. In this hobby, there's usually someone who sells what you want cheaper than the manufacturer. A prime example would be PML. Everyone's got their favorite store for PML kits, and it's never directly from PML. I'm simply asking this forum if there's another retailer who sells this product cheaper than what I've found so far.

I understand your stump, what it's stands for and why your speaking from on top of it, and I admire that. But I think your message missed its mark.

I don't think there are any sources other than Apogee.

That's unfortunate. I just installed Winroc, which is free. This should keep me satisfied until the $95 can be saved up. Out of curiosity, has anyone here used Winroc? What are your feelings toward it, and compared to Rocksim? #### HeadHunter ##### Well-Known Member . But I think your message missed its mark. Sorry didn't mean to offend...did sound a little cranky didn't I. Even made a typo on the engine that deployed 40 feet AGL. I think it was the F62T. I'll track down the paperwork if I can get my foot out of my mouth. As to winroc, it's ok but it does not have the depth of Rocksim. It made me want rocksim that much more #### shrox ##### Well-Known Member Originally posted by rstaff3 I don't think there are any sources other than Apogee.

I used Winroc to determine the CP and CG of my Bullpup and it worked pretty well. It's not *as* detailed as Rocksim, but it has enough information for you to keep you happy until you have the extra for Rocksim.
