5s A123 2300mah bat pack

First test, I had 6x4 sport prop and amps went up over 50 , changed to 5.5x4.5 and results were more reasonable. This sucker is gonna rock. Rite on...
Just remember it will unload in the air and amps will go down. Also the closer you come to matching the prop size in pitch (or go beyond it, over square) the less it will unload (ie 5.25x6.25) One of the best ways to test is with an (Eagle Tree) onboard system... hobbycity has the best prices on them...I'm going to get one soon myself!

Current Hobbycity.com prices (you need to be logged on for best prices)...
MicroPower V3 E-Logger $49.53
Watt's up meter: $37.46

Thanks Ken, I live by the Watt meter but the data logger looks interesting.

It depends on the motor and batts you have in mind. Was there two main spar choices? Which one did you use? A general rule for me is to butt the rear end of the motor up to the spar.

If its a 6cell setup you want the motor further back.

Nice video klique..

The last 747 in that video was landing at Kai Tak in Hong Kong, they have since shut it down due to the horrible X-winds in there..

I'm not sure but I'd say he's more like 25' off the bay..

Well, my wife said a box showed up today... Couple feet long, pretty stinkin' thin... I wonder if it's a TL50?

Sounds like your going lite, so yes, make sure the rear end of the motor is rite up on the spar. Push the servos as far forward as possible. A single layer of glass behind the cg and 2-3 layers ahead of the cg.

40" Demon maiden

Finally had a couple of days of good flying weather here in the heartland allowing me to maiden my new Demon. First, I went back over everything to make sure nothing was overlooked, high rate throws at 60% and low rates at 40%, neutral is flat from top of wing. Auw came in at 46.4oz , a little heavier than I had hoped but balanced at 7.5" without lead, though 3.5 oz of that weight is from a 6v hump pack used to power rx, since the A123's drop to nothing suddenly, a good rx power supply is important.
First flight was my tl50 to calm my nerves. The more I fly the 50 the better I like it, very smoothe and stable. After 8 mins of mixed flying, scrub off some speed and let glide back in. Finally getting the hang of putting it down where I want and not having to walk 50 yards to retrieve it Now, the moment of truth. There I stand, in the middle of a soccer complex, all by myself holding this bright new airplne in one hand, radio in the other, analyzing everything, is wind ok, no more excuses just throw the plane already. Throttle up, three steps and overhand throw...slight dip and up it goes, fast, very fast. Very steep climb from neutral control settings. I get it leveled out at about 50' and trim. needs a lot ot down elev to keep the nose down. Needs some thrust adjust. This thing is fast, cannot take my eye off it for a second as it covers a lot of ground and it sounds sweet. Controls are very touchy at speed, could be me or just need some tweaking but it goes where it is directed and vertical till I can barely see it. Now time to bring it down. I think Ritewings are harder to land than to launch, they go up easily but don't want to slow down enough to come in. Abut 4 laps around field scrubbing off speed, I leveled out and watched it descend and was a bit surprised as it was a very smoothe and stable approach and a nice sliding touchdown Life is good and the Demon is Rite.
A little fine tuning and this will be an awsome flying wing. Thanks Chris and all you RWA that have helped me cross over to the dark side.
