There were reports earlier about the canopy conversion changing the traits of the t28. Some thought it was putting more weight higher above the wing and raising the center of gravity vertically.

Mine had the canopy conversion on it when I bought it.

On the maden, I just put a battery in it and flew it. I found it super easy to fly and way more forgiving than a Mustang. I landed and took out all of the expo and dual rates I had put in for the maiden.

The Canopy can't do too much to the flight characteristics, because I can't imagine a low wing 4-channel plane being easier to fly.

Here are some of the pics transformed to be more circular, better centered and remove the prop. I printed between 1.22-1.25" wide depending on how you trim them. They look great.

I do worry about motor getting hot. Does anyone know if it gets hot? Small brushed motors don't last long. I wouldn't think heat would help any. I don't understand why HH doesn't use brushless. A few more bucks would be worth it.

Someone has done a brushless conversion. Hobbycity has a 1S brushless motor and ESC. The AR6400 has an option to connect a brushless ESC to the brushless motor plug. I haven't one the conversion myself but it is mentioned in the UM t-28 thread (the big one). I think the motor and ESC are about $15. Don't know the the weights are.

Would you have the link to the 1s motor? I did a search for what you mention up here, but I don't know enough to know which motor that could be. How do you determine that the kv is adequate?

I knew I should have taken more time on my other post but it was early and I was half asleep. But here they are.

Very cool Glen, thanks for posting the links!

If anyone attempts the brushless conversion, please post pics and procedures for the project!

The users guide for the AR6400L is at:
http://www.horizonhobby.com/ProdInfo...0-L-Manual.pdf

Refer to page 7 (middle of the page) for instructions on connecting a brushless ESC.

There is also an AR6400LBL which is a brushless Rx/ESC/ Servo combination. It costs about $70. Saves the cost and weight of an additional ESC. However this unit requires a 2S LiPo. I would guess this is the unit that goes into the Beast.

Could buy guillows kit for ten bucks at my LHS and not have to wait for it.
Havent flown it yet.It will be my first time with the plane lol I dont think it adds much weight.I think its worth it for the detail.

That is correct. It seems like that the foam could be trimmed to use a 2S. Might be actually feasible to up the whole motor/esc & battery.

About the canopy

The canopy I make for this model is original. I did the tooling directly from the Parkzone fuselage.
That is why it fits as well as it does.

Yes It does add a small amount of weight but is reduced when you remove the foam canopy .
I tried to measure the difference but my scale wouldn't pick it up.

If you use some common sense and don't go overboard with the epoxy and paint you will not notice a difference in the way it flies.

I have no idea how much glue the guys are using That have reported problems but that is the only thing I can think of that would cause it.
I only wish they would have let me know so we could look into it.

My mods are: Removable Canopy(It has Notches and a rubberband to hold it on.), and insulation for battery on bottom. I'm planning on converting it to brushless, and I want to keep it cheap. Would these work?
Motor http://hobbyking.com/hobbyking/store...idProduct=7230
ESC http://hobbyking.com/hobbyking/store...dProduct=10573

EDIT: Most Importantly, I changed the location of the battery to inside the plane, so I can open the canopy to put it in and take it out, so I don't have to insulate the battery place, and so hopefully it will have longer flight times.

The motor might be OK but the ESC is way to big. Refer back in this thread for a better choice of ESC.
