Default My Parkzone micro t-28



I've been playing with this one again with the new indoor season being here. It was my first micro single cell plane, and flew so well I bought 3 more. I was very suprised something this small could fly this precisely and look so scale like in the air. I did some minor modifying which enhanced its flight abilities and looks in the air. Heres some pics: parkzone t-28. I hope you all like them.

You were able to adjust the aileron throw? I opened mine up and didnt see any other servo linkage openings. I did change the rudder and elevator though

Iwas able to change the linkage. Inside the fuselage, the aileron servo connects to a bellcrank, then out to each wing. That bellcrank has two holes. Use the inner one. It helps to kink the linkage a bit to prevent binding.

Tape, funny name.

Mine is called Wreck, it hit the ground and trees so many times that it looks like one, but still flies!

I'd have to say yes. Its stable and gentle on response and can take a suprising amount of abuse needing little more than tape and glue to get it flying again.

Dean's right, IF you fly her over only soft grass and soft bushes the T-28 is forgiving and surviving. And keep her up, about a hundred feet or so, so you've room for error. Even though she can fly slowly, for beginning I started with something even slower without ailerons, the Ember 2. She's a good trainer for calm evenings and mornings.So is the Champ, which like the Ember is a three channel (rudder, elevator, throttle) and a little less complicated (see Champ thread here in MIcro/indoor and there's one under Parkflyers, too. The Champ has a HUGE following, like the Supercub which is also a great big-bird trainer). Any one of these birds would be great. Just don't wreck her on rough surfaces, and you can always come back to her if you get something different.

Just got back from the ball field with the "aileron servo" mod, it tested fine on the ground, so a flew it.. It definitively rolled better.....then....lost control and luckily got her down in a semi-nice weird crash landing. Noticed that the ailerons were stuck full open. Unplugged battery and re-plugged it in and they straightened out again, tested it and eventually it locked up again.

Brought it home, took the canopy off, connected the battery, and servo would get stuck and would only release with a push on the linkage with a screwdriver. Tried kinking the linkage several times to get it to work without getting stuck, but unfortunately I had no luck. It appears to me that the servo linkage angle in my T-28 is off with this mod. I think I would need to unglue the servo to line it up correctly, then try it again.

I ended up putting it back to stock, tested it, and everything is good again. Feel lucky that I was flying it near and landed on the grass...had I had it further....who knows how bad I would have wrecked. I had maybe 20% control as it spiraled to the ground with the ailerons stuck full open.

The linear servos (our short-throw ones, anyway) are touchy that way, S-Dog. When they are at the top or bottom of their range that seems to be where they can stick. I think it's in the little linear slot where it sticks, and not the actual motor. Here on the Gulf Coast everything rusts and I've taken to putting a drop-one drop-of LPS-2 inside the little rail.Haven't had a problem since butthis may be the mechanical weak link. They really are amazingly smooth, and not a problem even whenriddento the top or bottom of the rail.
