I bought the led light at My local hobby shop. However these are the same as Mine.

Hobby king are 3 feet long and there are different colors available.

They run on 11 volts (3 cell lipo) very well and 7.2 volts (2 cell) so so. I wired them together and to a female jst plug. I had a cheap esc so I wired 2 jst plugs to the esc and run the leds off the primary battery. ou can also make an adapter with a male battery plug and 2 female plugs if you don't want to cut your esc wires. If you look at the plane you can see a jst plug visible on the top of the plane. I plug it together for the light and unplug it if I don't want lights.

Battery recamendation

2712-17 1700 kv motor here.

I got the motor listed here and for an ESC i got a Castle Creations Thunderbird 18.
I have not learned how to figure the watts and such so i dont know which battery to go with. I want something that will give me some speed and verticle.
Thanks guys!

You can run the gws 7-3.5 prop on three cells for 15 oz of thrust at 7.5 amps and about 80W.

You need a battery than can supply at least 10 amps. To find the amps a battery can supply you take the capacity of the battery and mutiply by the battery's C rating. Also to make a 11 ounce stryker balance you need a battery between 45 and 80 grams in weight.

Here are just some examples That would work.

600 ma at a 20C rating (.6 amps x 20 = 12), this battery can handle 12 amps.
51 Grams in weight.

This battery would make the plane floatier but have a shorter run time at full throttle.

This battery would also work

800 ma at a 20C rating (.8 amps X 20 = 16) this battery can handle 16 amps of current.

71 grams in weight.

This battery would make the plane less floaty (I can tell the difference) but could handle the wind a little better and would run longer at full throttle.

I run similar batteries in mine. The little battery for slow and floaty and the big battery for long full throttle windly days. You need to place the batteries in different places in the nose so you can get the correct center of gravity. If you keep the overall weight below or at 12 ounce you should have verticle with either battery.

Here is my stryker flying in a single full court basketball gym. I might try to get a full throttle video soon to show the max performance.

I use mine with a 10 amp esc. that motor pulls about 9 AMPS with a 8X4 prop. You can use the 10 amp esc but I would use the 18 if you plan to run full throttle most of the time. remember to keep the build around 12 ounces with battery to have good performance.

To be honest that 1300 battery is a little heavy to balance well with that motor. You would have trouble keeping the plane around 12 ounces as well. If I were you I would go with this motor with a gws 8x4 or apc 7x5 for more speed. I would use the 18 amp esc. Those prop pull approx 12 amps witha 3 cell.

That price includes shipping. I have uses these guys before and they are good. Be aware they are closed btween feb 4-23.

I used this mount with a home made stick that fit.

I most local hobby stores carry this mount.

The slightly heavier motor would balance that battery better and with fan fold or depron fin you should still be able to get it easily around 14 ounces.

You will lose some floatiness but not much. The wing loading would go from 4.6 oz/sqfoot to 5.6 oz/spare foot.

so that motor with a 18amp esc and hxt900 servos and 3s zippy 1300 will work good, thanks cause i have 4 of these lipos and was looking for something to use it on, build the stryker with stock airframe, elevons and fins correct..

the stock elevons weight approx 1 ounce for both, and the stock fins are about 1 ounce each. I can make both fins and elevons for under and ounce. You could use the stock fins ans elevons but you would have a hard time getting the weight below 16 ounces. I would urge you to make you own from fan fold or depron, or 6 mm cell 88 ect. the shape of the fins are not critical and the originals are somewhat oversize.

Here is mine, ugly, quick and sloppy build but I don't care..... I may not even cover the electronics.

Why did you move the servos to that location? What did you use for the motor mount?? WHICH motor did you use? ESC? Battery?

Getting ready to start my StrykerLight.

A fool in a field.
I used old micro servos and the servos leads are to short. I just used a EPP block from a Superfly packaging and glued it and the motor on with goop, i'm talking sloppy here!.
EMax 2805 2800kv with a 5x5 prop from Headsup RC, Generic 18 amp ESC 1300Mah for power. Balsa Elevons and scrap EPP for fins.

Just got back from the maiden, flew just great!. Hard to tell since I have not flown my stock Styker this year but it seemed about as fast?, but far more nimble and will slow to a crawl.

Great simple project, I'm going to keep it as is. Leave the gear exposed, keep it ugly and have fun.

Stryker - How light can you go?

Greetings Ssteven1,

Nice modifcations! I'm going to put my Stryker on a diet and see how much I can slow it down. Thanks for the posting.

I built another one. These are quick to build, cheap and fun. This one weighs 13 ounces with a 2808 1450 kv motor.
