Not yet. But having seen Rich's Tempest flying the other weekend I'm very tempted to build a Tempest

I have a tame metal worker who can make me up the teetering head

PS: Electronics projects are still underway, and a little bit of video work as well. See the second video on this page: http://www.tnmoc.org/videos-elliott.aspx

Hi Bill,
I'd say you will be ok without cutting holes in the forward top section(Just my opinion). That top section provides a great deal of strength in the design. I have actually needed to add a bit of ballast(In the nose) to my RPG to suit my flying. I'm using a B.E.C with 3000 mah 3 cells, so I don't have the weight of a reciever battery. Your build looks great! Keep up the good work.

Regards,
-Mike

Hey....when is the maiden flight Rich? Did he say?

imsofaman · Jul 10, 2009, 11:17 PM

OK....got some RPG info for you guys.

With 4 cell A123 cells the weight is 4 lbs even.
Still using the BP motor
Changed over to 12x8 APC
Thrust = 3 lbs 8 oz.

Almost 1:1 weight to thrust ratio.

I may try the 12x10 next.

Sounds like that thing is going to work well Dave........

Here is a photo taken today of my RPG flying with its 3 bladed Aerobalsa blades fitted that I mentioned id been testing in my Thread.

Looks awesome Richie.

I just got back from flying. Again....fighting the high grass. Many runns and not working out, I moved to the other half of the field where only clover was growing and it was so much better!!! But....not much battery left with a short flight. A123s drop off FAST as you will see from my landing!!! LOL!

I thought I was going to have to shove the batteries way up front...but actually I moved them back an inch.

I am enjoying trying different things with the RPG. Such a fun little gyro!!
