Now with a battery connected the motor will spin up but sort of miss or pulse. The 2 onboard servos refuse to move. the external servo responds normally. So the receiver is fried.
My question is whether to buy the AR6410 replacement or the AR6410L? I can't seem to find this information anywhere. I am leaning toward the long throw and setting the throw in the 6Xi.
Help anyone?
That sounds typical of a shorted brick. RCG member Chimchim has fixed burned bricks for me in the past for $25. You may want to contact him.

The long throw bricks are better. If you don't need the extra throw, you can always move the pushrod out on the control horn. The added throw gives better feel and precision.

I wouldn't pay $60 for a new brick. Used or buy an airplane and take the brick out of (and sell the rest) is cheaper than buying just a brick.

Got more time on my T28 and it just keeps flying. My favorite after I made it 2S brushless.

Heard a rumor from a guy at the LHS who told me that Parkzone was going to stop selling the UM-T28.

With the popularity of this plane I can't see them doing that.

Has any one heard this?

Maybe they are just discontinuing the current model and will have a new model with brushless power and AS3X onboard

That would be nice Kman.

Flew tonight with my 2S brushless T28 and both wings collapsed on a quick tight loop.
I knew this would happen sooner or later. The Trojan tried to tell me.
Rockets don't like tight loops.
I reinforced with a carbon rod and she's good to go.

Flew my 2S brushlessT28 after I used a carbon spar to stiffen and reinforce the wings. The wings collapsed on me on the last flight.

It's such a different plane now. The wing is much flatter remove some of the dihedral.
Rolls and loops are much quicker and cleaner.
The fear of tearing off the wings are gone.
Always was my favorite and love this plane even more.

Any idea how the weight compares to stock? Sounds like a real neat conversion.

Thanks goodhumourmarc for linking to my post.

Flying weight came in at 56 grams.

I converted to. 2s BL in January and must have >+100 flights on this plane.

Man, I haven't posted here in months.

I've been flying the UM T-28 more than any of my other planes - including my much bigger Dynam T-28.
You just can't get a better flying ultra-micro than the T.

I'm done with replacement motors, bigger- fatter props and other enhancements, I just enjoy flying this lil bird all over the sky. And all the guys at the field stop and watch.
They ask all kinds of questions about how fast, how slow and how much does it cost with or w/o a tx, et al.

This plane is #1 in my book.

Hey, Blacksheep!
I like your avatar. Just so happens I'm reading Gregory "Pappy" Boyington's biography "Black Sheep". I'm still reading about his younger years, but he had a rough childhood that was more or less saved by his love of aviation.
Boyington was a true American hero, despite his wild side.

Very nice KC and neat. I've wanted to do what you did and might on my next 2S BL conversion.
Reinforce the wing. A very different plane.

There is no rudder servo?
How does she fly?

A list of components would be appreciated.

Thanks, it's a really good book. You'll like it when it starts taliking about his involvement in the war. I especially enjoyed reading about his time with the AVG (Flying Tigers). I do know what he would say to you calling him a hero though, "Show me a hero and I'll show you a bum". Quite a character.

Thanks. Got everything except for the 2 Turnigy servos.
Did the servos have the right connectors for the OrangeRX?
