HK can be a great resource if you approach buying things from them fully aware of how to do it.

Pointers:

- EMS, yes it costs a lot, but normally you'll save the expense on the first item you buy... so buy several things at once.

- ALWAYS buy things that show as "IN-Stock". If you want something that is backordered, set an e-mail reminder for that item.

- Always limit your purchases to things that are unlikely to be returned for any reason.

- Weight your box when you get it, before you open it. Check the contents IMMEDIATELY.

- If anything is missing or in error, take individual digital pictures of everything and the box... also a picture of everything in one shot.

- If you e-mail their order support people, it can take a week before you see a response. Check your Anti-spam message filters.

- If you need to converse back and forth by e-mail, each exchange can take a week, so always start with your order number and a copy of your receipt to avoid questions. If you are missing something, include the photos and weights, which will save you two weeks of back and forth!

- If something is missing from your order, e-mail them and offer that they can include the missing item in your next order, or better yet have them issue you a points credit useful for your next purchase.

- Certain combos and weights will flag attention and delays at customs.

e.g. 4 heavy packs sail through... but my order for 12 such packs was delayed for a week more. Maybe someone thought it was a bomb?

I've ordered glow engines, gas engines, servos, 100 some LiPo packs ( some of those LiPo's are GREAT BTW!!! The Nano-techs are especially good. ), mounts, electric motors, ESC's, EDF's, etc.

All have been great.

Note that I find their specs on the gas engines to be highly inflated... Expect about 60%-80% of the stated power output levels.

Check the specs... read what others write on the review pages... these are QUITE helpful to avoid problems.
