That looks to be a pretty hot setup. You'll love it!

We need videos!

Nick,

What sort of speed are you getting and on what prop?

I have a NIB kit of the .10 size Shrike that I want to build. I saw a 1/2a size version of this on brushless power during E-week and it was very cool. So, I want to build mine and was wondering what to power it with. I have a spare Eflite 60 amp esc and was looking for something in the 400-600 watt range that will yield 120-130mph with an 8 inch prop on 4S. Have you tried this motor with 4S? Just curious if you could share some numbers with me.

Sarge,
I have been running a 9X6 on 3 cells... That is a bit much.... I think that on 4 cells with an 8X6
or perhaps 7X6 you will see 120 with no problem. Just be sure to use a watt meter to test your set up and remember you will draw more power (25%) or so static than you will in the air. I'm getting better than 100 mph with my 3 cell. This plane is clean.... so start the landing pattern early.

My next SHRIKE will be a little bigger and have eflite electric retracts....

Sarge,

Forgot to mention it but the data on the HeadsUP site is usually very good regarding props and power setups. This motor will produce 500 watts... I think that you will like it.

Hopefully this winter I'll finish my 43" one. Like my 35" one (this build thread) it has E-Flite electric retracts, and they really help slowing it down.

Thanks for the info.

I have an eagle tree data logger that can be used as a real time wattmeter also.

Looking at the data on the website, it looks like an 8x6 might be pushing it on 4S, but a 7x6 might be better. I think I'm going to snag one and get started. I've got a 60 amp E-Flite pro ESC and ZTW 80 amp ESC that aren't in use right now.

I fly a regular Funjet with the 400 watt Himax Funjet Ultra motor and Graupner 6x5.5 prop and it's in the 120mph range and probably similar to the Shrike in terms of power off glide (Funjet takes a while to bleed off speed and settle into a nice glideslope also.)

I just finished up the second micro Shrike over in this thread. Can't wait to fly it!

http://www.rcgroups.com/forums/showt...0#post23000345

I picked up a kit for the 24" one at a meet this summer. The plan is to build it mostly stock. I'll probably start another thread for that one.

So I've finished 4 Shrikes of various sizes and have number 5 (43") sitting on the workbench and plans for #6 this winter. I think I like this plane!

Andy,

You did a great job on the build. Unless I missed it, what is the AUW?

I'm trying to limit what I fly now to the lot by my house. It is just too easy for me to step outside and fly.

My big bird is reserved for Fun flys and those rare (now) trips to my club field.

Thanks,

Frank

80 grams? Like 2.8 ounces? You are pulling my leg.

This is an ultra-micro. Yes, 2.8oz. Same weight as a micro Stryker.

The big one with retracts and all was about 35 ounces IIRC.

Andy

Edit: Just found this over on RCU in the "Shrike Club # 1" thread. To quote myself in post 709:

Quote:
Mine (with retracts) is 2 lb 8oz with 3S, 3 oz more with a 4S.

Great build and you did a wonderful job on it.

This is the 30" Shrike build thread, but I recently added a note for the micro so that's what I thought you were talking about.

The actual micro build thread is in Electric Plane Talk - http://www.rcgroups.com/forums/showthread.php?t=1561429

I have a 24" one I'll be building this winter and will probably put the thread for that one over there too. I suppose I could do one for the 43" version. I have all the photos, just need to post them.
