Hi Jeremy,
I haven't flown R/C in years, so I needed something to get me thru the learning curve that would be fun to fly. Slow is boring. I saw one of your wings and just had to have one, so I ordered the sledgehammer a few days ago. It said beginner and I would assume that is dependent on the power setup. If I'm left to choose the power system on my own, I figure it will end up in Toledo before I figure it's time to turn it around LOL So, can you give me your recommeded power setup for a newbie, to get me thru the learning curve of electric r/c? Please be specific as to make, model etc. Did I mention I'm learning Greek, as most of the posts are greek to me.

Seahag721 , you are correct when you mentioned beginner and setups. We include in the instructions a variety of design ideas as well as giving the builder suggestions to help with future upgrades without buy another wing or major mods.The Sledgehammer can be built as low as 25oz and as high as my current one 60 oz. Both are hard to land because of the high lift aspect of the airfoil. You will have to practice landing because it doesnt want to,lol

Servos-I use full size Hitec HD's with the karbonite gears. Even at about 150mph they are very responsive and durable.

Receiver- I use a hitec super slim 7. I just recommend any that has horizontal plugs and full range. Most use electron 6's from hitec . If you have something other than those mentioned and havent had problems use it. Please do not use Gws micro types or even Berg micros. They seem to have issues in most wing setups due to equipment locations in close placement to the receiver.

Esc- we always under rate our esc by about 25% to allow a safe margin. I use a 70amp in my 6s setup but have used a castle 25 as well as a Great planes silver series 35amp with no issues. These are based just off of the motors and batts used.

Motors, For 3s setups for 2100mah up to 5000mah batts you can use a HET 3 turn on a 6x4 apc sport prop.(can be run on 4s as well on a apc 5.5x4.5)
(3s -90-110mph 30- 38 amps)
(4s - 110 - 135+mph and 45-50amps?)

Het 4 turn on 4s 2100-5000mah and the same props. ( about 38amps Wot-and 115-118mph)

Het 3w-25 on 5-6s 4000-5000 20-25c and a 6x5.5 apc and 60-68 amps wot.
(about 148-152mph) 54oz - 60oz AUW (2 - 3s packs series)
battery eliminator required on and over 4s setups.

Feel free to contact me once you have a general idea of what you are going to use. I can help with the equipment layout or with equipment selection. Keep it cheap where you can. Warbirds -rc haqs the Het motors for about $50 shipped and great customer service. If you already have a motor I can run the specifics thru my program to give you an idea,
Jeremy

Hi Jeremy:-) Got my bird in the mail today. Thanks! My girlfriend is stoked. I think I upset the local hobbyshop guy though. He is an older gentleman and I don't think he understands the "need for speed" Yaaaaaaaaaaaaaaaaa! Sorry, lost myself for a second. But you've got to understand, they fly the same stuff every weekend. (Boring) Crashed a few too. If I'm going to crash, it's going to be flaming!!! Although I'm aging, 21 for the 30th time, I'm not quite as old as he is. He's trying to talk me into a slow flyer. No way! These boys need some excitement here is south Texas.... Anyways, I'm getting things together and I'll post a few pics on the progress :-)
