They state on your invoice to contact and tell them if your order takes longer than the time they quote for shipping. Which is ridiculous in how it is quoted to begin with. Shipping options from their site depend on what item you are ordering (not just batteries either), I logged in and put a single motor in my cart, these are the mailing Options; Option 1 is 8-16 days for $5.50 for a single 1106 Micro Brush-less motor 3400KV (Shipping weight is. 135 Kg). Option 2 is 3 - 4 days for $21.49 (LOL). I have ordered several times from this company, shipping is ALWAYS painfully slow. My orders always seem to be delivered on the last day of the week - month range stated by Helipal or the day after the last day in the range. They rarely (almost never) provide a tracking number. The shipping options they provide are inconsistent. I am waiting on an order that was shipped on the 19th of June according to my invoice. Today is the 2nd of July. 12 days. The item was to be delivered 7-15 BUSINESS days, non-work days don't count, (FIRST GOTCHA). It's been 12 days but only 9 business days. If it arrives in 15 business days it will actually have been 22 days (that's a whole extra week they are covering their $#*! with). If you need a part and its not on E-bay, not available in any other country or from any other supplier or the manufacturer, and you cant cobble it together with sticks and glue, but Helipal has it then either you pay extra for express shipping (which is also always late by the way) or you wait for the slow boat.
I'm done with them. I have lost weeks of flying cause they cant seem to find the DHL truck or a reliable shipping process.
