My Champ and the Champ of a friend both lose power occasionally for no apparent reason. My UM J3 which uses the same transmitter has never lost power.
The power loss can last for a few seconds and return on its own for also no apparent reason or sometimes reducing throttle and reapplying will resume power - that is a sign of a brownout but the brown out may not be due to the transmitter.
Personally, I believe the Champ has a defective "brick".

It could be a bad solder joint in the power wire or motor plug, too.

I've had over 30 HH micros and have seen this many times. The Rate of bad RTF TX's is pretty high, too. Probably higher than "mystery" intermitant problems with bricks.

It could also be from a high resistance solder joint that triggers a LVC at higher amps, but is OK at lower amps (on the board or at the motor plug).

Replacing the motor helped most, but a few needed the board resoldered.

The Cox skycruiser is a toy with a toy TX. The Champ is a real airplane you can fly with a real TX that has components you can scratch build your own micro planes.

I have flown almost all of the micro planes and the Champ is one of the best flying planes ever built.

I've handed the Champ TX to 8 year olds and they have flown it fine and move the pushrods in on the control horns and its a ton of fun for an experienced pilot.

Who flies around the goal posts, anyway? Can't they see their is 300+ X 100 ft of clear field right next to the goal posts?

The champ also teachs you how to land and take off. I'm not sure a sky cruiser is capable of that.

I picked up my Champ on March 2 and the stock Horizon battery is already not taking a charge. It's been used maybe 10 times. Looks a little puffed compared to the new 150 eflite I got Friday. Is this normal? Not the puffy part, but the ten flights and there done part. I normally leave the lipos uncharged for storage, but maybe I drained this one too much.

unless its a new 25C battery, its likely over a year old (even though you bought it March 2)

Yeah, I thought so. But how many cycles will the new batteries last? On my bigger planes that use 1350-2200mah the batteries are a year old and cycled probably 50 times. Should I be worried? I have a pretty decent Common Sense charger for those. I read that even these little battery chargers charge at too high a rate.

I had no idea you could hot rod a Champ that much! He has good flying skills too. I just can't believe the wings don't come off.

I buy store return planes from hobb-e-mart and have acquired many of the E-flite 150's. None of them has ever worked. They are crap.

Hopefully the 25C ones are much better.

Just buy 6 - 10 160 nanotechs from HK every 6 months. They are great batteries and if you kill one, its less than $1.50, so its no big deal.

Yes, it is normal. Some older or newer cells fail sometimes.
I have had all makes come up defective early.
If you land at the first sign of pulse or power loss, you are probably ok..
If one runs the battery low, then forgets to unplug, I think it could really run down the cell and damage it.

I never had a pulse or brownout with the plane so I will assume that the batteries are crap. Probably the reason Horizon discontinued them. Flew the Champ on the new batteries with 25c, but I was way more conservative on the flight time. ten minutes mix throttle. Old battery was like 15.

David, I fly at the Rosebowl and the Champ will probably nose over in any grass that is over an inch tall. It flies so dainty like that it won't really hurt it though.
