The CC HV would solve it all, except for my motor selection as of now.

For now, I dont plan on running over 250 amps, so parallel is definately a necessidy, even if not cresting 250 amps. Remember, I dont need 2 identical packs for parallel, just identical mAH and "OVERALL" C rating for series. The calculator has been getting its buttons worn off and this leaves the doors WAY open for some very "out of the box" thinking.........The MOPAR way !!!

Still no decisions............ (heck, even if I did decide, I just might NOT let anyone know untill I fly and see how things turned out !!)

Key is to tighten with only 2 fingers, then allow the Loctite to set-up before flying. This keeps those pesky tabs from breaking.

There is a motor mount design being worked out now, just about ready for release, but still in R&D phase. Stand by a few more weeks and lets see what we can come up with, till then, even I must stick with those pesky stock mounts !!!

Well I put some nice big washers on my stock mount to help reinforce the screw tabs. I strapped a KDA 2300kv motor on it and gave it a shot. 45 secs. into the flight something went terribly wrong. Im not sure what came loose, but my stryker just took a 90 degree turn and nose dived from about 50 feet.

I got 4 months out of that wing, sucks though because the airframes are backordered.

I was stalking around the part 8 build thread this morning while attempting to not do homework, and I came across some shots of peoples propellor stashes. Mostly notably was gryphons (quite impressive I might add Gryphon!). So this inspired me to capture some images of our "neccessities" and share them.

Of note should be two things
1) No prop was photographed twice
2) ALL props have been balanced to ensure vibration-free running

Doctor Audio has inspired me to incorporate my next build with C/F, so I took a picture of some of our stock as well. It should be enough to cover the stryker a couple times over Anyone want to take target practice, lol

On my next one I will use this stuff on the leading edges.

4.7 oz. 80/20 Carbon Fiber/S-glass Fabric 38" (per Yd.

Then I will wet it with epoxy and squeegee it then lat it on the leading edges. So you have to let it slow cure!
I am sure you know of this technique!
later

Kid,
Stalking around part 8 is a good thing !!!!!
Also good is that NOW I know whom to turn to when I start on my NITRO endeavers !!!!

You 2 (Gryphon and You) are just about at the point where I need to take pictures of all of my props too !!!!


****NICE STASH !!!!!!!!! ****

Doc, you should go with the 22/30/2! 6s and a 6.5x6.5 or better should see you and Shake and Bake to some silly high speeds!


Mopar, you should stick with the E-stuff. Nitro is too messy. Unfortunately for us its like 72 Mhz, at this point we're in too deep to get out (Thats what she said, for those that get the joke).

Although, now that I think about it...A Stryker with a OS.15DF could probably do alright. It should turn a 6x4 at ~32k. That would be good for just over 100, right?

DoctorAudio,

I don't like that motor's overall specs (22/20/3)...even though it is a MEGA.
Edit: It is great compared to many motors from China.

For almost any case you can make, I should be able to point you to a better MEGA motor with minor price difference.

If interested, I can help you in some PMs.


p.s. I do have a 22/30/2 for one of my Strykers.

Hey all finally did the maiden of the Aurora and I have to say I was impressed with the first flight. I didn't use the bungee instead I chose to hand launch and it was almost a bad idea it took quite a bit of arm power to get it up speed before she started to fly.No trimming out was nessarry as the elevons were set up dead true to the inboard and outboard surfaces of the wing and she flew perfectly just like that,launch mood was set at 25% up elevons.I don't want to speculate on how fast she was I think I will be able to get a video of it in the next few days and post it all I will say is it hauls a*# and is rock solid in terms of flight charicteristics and landed at about 20-25mph.

blanik213,

Congratulations my friend......I'm soooooo happy for you.

Your Plane is not only a work of art; it is also full of high tech details, more than anyone knows.

Bravo, you deserve a standing ovation.


I know it'll be a matter of days before you say: "I WANT EVEN MORE POWER"

When you do; YOU ARE MINE


I look forward to your future posts.
