Nice video!

I will do my best never to complain about lack of good flying spaces in my area again. Hats off to you!

It looks like its feasible. Dont go too big on the prop

hehe, yep I have definitely had to adjust my concept of "close quarters" since moving to the city. All the light poles, buildings, etc, almost gave me a heart attack the first couple of times I flew down there, but now I just have fun .


Oh, did you see the helicopter at 2:22?

See and avoid!!!

It should be OK but will be noticably slower than stock (910kV vs 980kV). You should consider upping the prop to a 10x8 to get comparible performance. I tried a Turnigy 35-36 910kV (SK) in my T28 and was a little disappointed... but should have tried a bigger prop (I didn't think about the numbers back then).

Bargin priced, give it a whirl.

You could probably use the 1020kV if you want more speed. http://www.hobbypartz.com/alpha-480-...ess-motor.html

wow. sure makes me appreciate Dallas. We have lots of open space here.

Drove around for two hours looking for a place to maiden. Almost gave up but, decided to give it a try. I was on a dead end road near Port Costa Ca. Takeoff was easy enough, flying was interesting. The plane seemed to work well, much more responsive than the stock SC. The wind was 5-?, very sketchy, as there was a hill on one side and the Carquinez Straight on the other. I eased her in and landed on all three wheels. The only problem was I pogoed about a foot. Great plane. I will have fun with this. Going to reinforce the nose wheel area. Thanks.

Anyone know the max pitch and size of prop you can put on the T-28 w/ the stock setup?

Someone mentioned 11x7 as the max on stock gear.
I run a MAS 10x8 Beechwood on my T-28 and it does very well.
Haven't tested amp usage though.

There are very few official stats out for the stock motor. People have calculated / estimated the max watts is ~330W to 350W.

With the stock prop, my motor pulls 220W, so there some room for more power. 11x7 or even the 10x10 will probably work, be careful of the 10x10, it draws 505W on my 1100kV motor.

Don't forget to ensure you don't over-load the ESC and battery. Also cutting some of the cowling open to increase ventilation will help.

Flight times will drop too, so start conservatively.

Cool video man. The weight shouldn't be to bad, just keep the nose down, speed up and make a longer roll out. Actually a little easier IMO to, the plane stays further away from stall speed.

Yeah, it handles the weight nicely. I've even flown it with a big 3000mah Lipo, AND the camera! She will drop the nose more in turns, so it helps to coordinate with rudder. When I can afford another Hobby King order, I am definitely going back to 3536c...

As for the rollout, it's going to be hard to increase that by very much. I took the gear off to save weight (and because I'm missing the nose gear...).

Ahh, that's why it skidded sideways. I noticed the hand launch.

Also with that much camera, check the COG with the camera on. Cool area!

Yes, I wasn't just getting overzealous with the Parkzone brake technique!

She is definitely a bit nose heavy, but the battery is back as far as possible without sitting on top of control rods, so I'm ok with that. I would like to try some different camera locations though. I noticed a few folks using "crappier" cameras get clearer shots with less vibration, and more of the ground in the frame. I think when I get new nose gear I will try mounting the camera on the bottom facing rearward.

And then it's movie watching time!

Here are the pixs of my T-28 external flaps made from a 1# salad mix container lid. Pretty simple and works great. later, Ed
