Hello everyone. I haven't flown a Stryker for about 5 years. I did have a brushless motor, glassed fuse(sandable epoxy anyway), carbon fiber tubes, so on and so on. But given how long it has been I sure could use a little setup help. I am going to build from scratch with my son. Still going to epoxy and carbon reinforce. I think that we are going to use the E-flite six series 2700 Kv unless you can give a better suggestion in that price range. Will the Eflite 40 amp ESC be a good choice? What prop would you recommend? My son is just learning and don't want too much too fast, but still want something fun for me.
Like I said it has been quite a while since I have been in the elec flight game and need your help.

Thanks in advance for any info.


Hi Firstman ............. and welcome !!!

Sorry for not getting to you sooner,

The E-Flite 6 series is a good motor, but you could get better for your $$$
With a 3s2200 (45/90c) battery, the APC E 6x5.5 prop will want to draw about 50 amps
Its tough to reccomend a prop untill I know about how much your AUW will be.
It is easier to launch with a 6.5 or 7 inch prop, but I am not sure if you are comfy doing so.

My favorite setup for fun with the 6 series 2700 (if you already have one) is with a big 3 cell and an APC 6.5 x 5 prop .............. You will need an 80 amp ESC as a minimum though.
If you want something slower with great thrust, an APC 7x4 will be great !!!

Status: offline 		Make sure that you use the dual rate of a radio for initial flight. I'd suggest something like 60% and 25 expo for low rate and not that much faster in high rate. Once you see how predictable the plane is you can always go up on the rates.
Insure that the elevons are nice and neutral for up and down and just a tiny amount of up on the right and down on the left for a starting point. By tiny I mean just noticeable.
Something that I do that helps me on launch is to build in about 20 degrees of UP flaperons into the setup for launch. That way, its automatically giving lift on launch and once both hands are on radio, I just click OFF the UP flaperons to fly as normal.
Once trimmed, you will be amazed at how stable and bullet straight it flys. No surprises. It tracks like its on rails. Careful touch on the levers will prevent any dodge movements.
Make sure you are balanced perfectly on the nubs provided in the launch handle area. Anything other than a perfect balance at that point will cause the plane to fly poorly.
Land with zero throttle, Let it glider in from a couple hundred feet up at a slight downward trajectory. Once its lined up and close to the ground, keep the nose just slightly up....don't try to flare it.....it will and drop like a bowling ball. Just enough up to keep the nose out of the dirt or grass.

You can find them in any Walmart or hardware store.
This is what they look like. Plastic Hooks

It's been along time since I have been on this thread, been flying a hei and that is because I could fly it my yard.
I been laided up with bad back and neck probems and fighting with BWC to get approved for surgery.
So I see the thread is still going strong .
My question is for the guys who are using big lipo packs.
I wanted to run a 5000 4 cell and I have already put weight on it beefing it up and the pack is 542 grams , are you guys still hand launching or do you have to catapult them ??
Thanks Everyone

But, lets say you do: I think a lighter weight pack would allow you to attain a higher speed than the larger weight pack.  4 cell is still 4 cells, 3200 mah or 5000 mah. 
Speaking with absolutely no experience in what your attempting to do.

I know about the weight, I'm just trying to get more flying time as it will be using allot of amps.
I know some guys are using bigger and heavier 5 and 6 cell packs along with heavy airframes, but I don't know if they are hand launching them or not.
I appreciate your input and trying to answer my question.
Thank You
Joe

At the end of about 6 to 7 minutes, I'm ready to land it.  I'm so darn tense from having to pay such close attention to that lil' bugger, I look forward to landing it   Frankly, it scares the hell out of me, but I keep looking forward to flying it.

If I use a 2200 pack in my new setup, I would have to land by the time it would take to get it up high enough to trim it, I will only get 1 minute plus still keep my 25 percent safety charge.
I know how exciting it is when they are moving that fast, I should get at least 100mph if not more with my new setup .
I also keep mine glow orange & glow yellow on the bottom with black trim .

Thought i would pop in to see what's up
Just a refresher I'm one of the "elders" on this thread.....so that said
What have I done in the world of strykers.

Still flying a screaming high kv model

Also enjoy ing a long flight time model
old scorpion motor 22mm
8x6 MAS prop
watt meter with full charge... WOT a big 12 amps
3 cell 3000 ma pack
longest flight 21 minutes
speed 45 -55 mph much like the orginal a model brushed motor and NmHi batterys....those where the days

So how long can YOU fly on 3000 ma 3 cell

Now my flights are with very little throttle management ....so wot most of the time
I'll post pics and vids

You need a good arm, but it is easily done.
However, with back and neck problems - you might wish to keep it as light as possible

Was that you flying the Stryker in the video , it was sure fast.
Was that a 36 size motor in it, and how many cell and mah pack was in it, I see it rolled over after launching it.
That is why I bought the 3 axis plane gyro unit hoping it will keep it level until I can get my hand back on the stick and get full control of it.
Thank You

Hi joe1,
Yup, that was me.
Its a 36mm MEGA 22-70-1 with a 6s5000 (45/90) and an 8x8 Sport prop. They all roll with 8 inch props !!!!!

If you keep it light, all you need is a little toss, allways remembering to hit your leg with the throwing hand as you release your Stryker no matter how big or small a prop you run !

Status: offline 		Hi Moparmyway :
My setup is a 2250 kv motor with a 7x6 apc prop, and a 4 cell 4000 mah pack , so it will be lighter then yours for sure.
I could hear you cut back on the throttle except for your full by pass , but even then you did not get but maybe 1 /1/2 to two minutes of flight correct
As for throwing, I had not thrown one for a couple of years and I got a slow flier that is made of flat foam and it is based on a Stryker.
It uses a 8x6 prop and I forgot that with it, I have to throw and then give throttle, while I was throwing the Stryker with no throttle and kept noseing it into the ground.
So I toke the flat foam one and gave it full throttle and it cut me from the middle of my arm all the way down and got all my fingers real good.
I had the throwing on the two ass backwards :=}} {{ ouch Ouch .
Thank You

the trick is throw it like a football
aim about 20 degres up from level
I use WOT on low power stryker cause it just flys at about stall at launch
On high power about 2/3 throttle
So about 2/3 throttle arm back as to throw football
aim ...throw snap your arm down after release

Now that said I have a bad rep. around club as having a wierd throwing motion ( no NFL for me)
If your uncomfortable then spend 15 bucks or less in a bungee launch system....hobby king usa has them if i remember right.

On my high power plane I usually have my flying buddy throw it...youshould see how far and level he can throw it with not power..he's like human bungee launcher.!!!!!!!!
