Just make sure you have your ailerons, and flap leads hooked up before using the glue.

VELCRO!
I was having the same wing problem..Tape worked for a while and today after adding flaps I glued the sucker on...Hope everything is hooked up right!
Going to try it out late this afternoon...Dart

Receiver Layout & Tips?

Hello All. I've recently purchased a T-28 PNP along with the necessary peripherals (AR6200 and 2200mAh Zippys). I'm taking today to put it together and was hoping for a little advice.

First, where do you all put the receiver? Do you tape/velcro it down? What about the antenna? I'm assuming the battery sticks right up the middle...and I did plan on velcroing that down.

Lastly, I've taped the leading edges...but should I put some elsewhere? Do I need to "strengthen" the hinge points for the rudder/aileron?

Any help is appreciated...thanks!

Welcome to the wonderful world of the T28!
Here is a previous post with alot of good info in it. I too would be interested in seeing the inside of some planes and how people fasten down their batteries, RX etc...

Sorry for the double post, ment to post here, but posted in the Gen Park forum, so here I am in the right place....



New T-28 flyer here. Did the maiden today and did fine except for landing. I fly behind my house, perfect place, about 20 acres, except for landing, got tall cedar trees on one end of my LS and a fence on the other end.


So, I'm haveing a problem there coming in too hot.

So, I think I would like to have flaps to help out in landings.

I got a stock PNP and a stock DX6i. There are extra servos in the box with the DX, Willl they work for flap servos??

And can I use the stock ESC and the stock 6100 RX??

If not what do I need??

Dagwood,
I would recommend practicing your landings more to get them spot on, exactly where you want them. The flaps will help, but you can learn to put the T-28 down in a small, select area, and I think its worth it to learn how.

As far as those spektrum servos and the stock esc, I would hope to hear from someone who has tried it. Adding two servos might max out the internal BEC on the stock ESC. Worst case scenario, you add an external BEC (battery eliminator circuit, which supplies regulated juice to the radio).

When I installed my receiver I couldn't put it in the little area reserved for it. The wire from the esc wasn't long enough. So I velcroed it just in front of the little box area where it normally would go.

Try flapperons first. Don't need to put in any servos or cut any foam - just take out the y-harness and program your TX.

I've read that this will cause an undesirable effect and ill mannered handling. A simple search will provide with more than enough previous experience.

If you really want flaps, wait for a few days of bad weather and cut real flaps out of the wings. Its an easy mod with plenty of info on how to here.

IMO though, the T-28 flies wonderfully stock

just my .2

not claiming to be expert at this at all, but I just thought I would upload a vid of landing my hotrodded Trojan in a relatively tight space with no flaps. Fastforward to the end for the landing. It's all about keeping some power on and avoiding the stall. You can hear me cut the power 1-2 second before shut down.

I had been landing right on the snow a few days before, but it warmed up and lost the crusty top layer.

its easy to land the t28. No need for flapperons, flaps, spoilerons, or any thing else. Its flies nicely stock. It pretty much floats in to where ever you want it to. Practice makes perfect!

I love my flaps. Yes I learned to land it just fine without the flaps and flew it like that for a long time, but I like it with the flaps.

Guys

I want to discharge my Lipo's for storage till the weather improves and I can take out the T-28D again.....

My balance charger can discharge the batteries but at what rate should I discharge them at? 1amp?

That batteries range from: 1800mAh to 2200mAh

Is a 1amp discharge rate safe enough?

Thx

If you are adding flaps, you will need a separate BEC. The stock BEC on the controller is only good for 4 servos. I used the Castle Creations BEC that costs $21. The t-28 does not need flaps but they add anther element that is fun. Someone recommended the following flap settings and after trying several different amounts, i agree with his recommendation:

Flap position 1 for takeoff: 10 degrees and Flap position 2 for landing: 20 degrees.

Hope this helps.

Rick

Sounds like they dialed in too much. Didn't have any problems with mine unless I was landing into a good wind - in which case you don't need them anyway.

Yes. 1a discharge on 1800-2200mAh batteries is perfectly safe. That is a VERY low discharge rate. Anything at or below about 1/2 the rated continuous discharge rate should be safe although most chargers wont discharge a battery anywhere near that.
