CZ T28

[AkumaZeto]

Torn between the v4 FMS and the CZ. Thoughts from fliers out there?

[CZ Flyer]

I have the CZ & love it, but i still want the v4 fms! Landing gear issues with the cz however. Nosegear bends constantly if your landing isnt perfect, plus my right main retract just burnt out, almost burning a hole in the wing. Fortunately Horizon is sending me a new retract for free. That being said, I'd go for fms because the gear is better. Let me know what you decide! Ron

[AkumaZeto]

Yeah the gear is all FMS from what I am understanding. So the strut itself bends like a dynam, huh lol.

What is carbon Z construction? Is there wood in the foam? If so are there cut aways to show it?

Only wood i see is the battery tray. Wing spars are fiberglass & carbon fiber. I guess thats where the "carbon" z name comes from

[AkumaZeto]

I was always under the impression there where slats in the wings like a traditional balsa build up

[AkumaZeto]

figured I could get some real world impressions here from the folks at Motion Rc. They are all at Oshkosh though. I did invite the entire crew to my house though lol. They drive right through my town on way home!

[AkumaZeto]

Can you give more thoughts on the model? Issues you have had and how it flies?

This is my maiden last fall. I've been flying this thing with little incident (except for burnt out AIL servo, which HH replaced) and a wheel cover that keeps breaking off due to the extreme bumpiness of my field). It's a big foamie airplane that flies great. It can fly very slowly (as seen in the video) and can land very slowly (in fact, gotta keep the speed up a bit). It makes great sounds when doing a fly-by. However, it doesn't stand up to hanger rash very well but then, none of my foamies do. My biggest problem with it is transporting it. If it was perhaps 1' to 1.5' smaller wingspan, it would be perfect. I don't take the wings apart so getting it into a little Golf takes a bit of forethought but it does work. When I go to the field with it, I can't take many other planes with me.
PS. The AIL servo quit in mid-flight and yet, the thing just kept on flying. I couldn't figure out why the roll rate was so slow but I flew OK and it landed without problem. Bigger planes seem to fly better and the bigger they are, the better (and more stable and easier) they fly. My CZ Cub was the same way. Both are like big babies in the sky but when asked to, they can tear it up.

Well I want a 5-10mph+ wind flyer. As it stands now all my other birds dont like wind. All my 1400mm FMS birds do OK at best with a slight breeze. My zero...forgot about it that thing is so light. My corsair likes to ride the wind shifts in the air lol and my mustang has barely enough power on a calm day. HOWEVER my Nitro Planes A-RC 1450mm t28 LOVES the wind. It laughs in its face. Maybe it is just the design of the T 28 but I will note its also prob a 6+ lb plane.

Flying in wind is a matter of 2 things:
1. The pilot's flying skill.
2. The plane's power to fly against it.
The CZ T-28 is a big, powerful airplane. Wind doesn't affect it much but then comes the pilot's ability to fly it in the wind. Additionally, if you get the one with the AS3X Rx, a less experienced pilot can handle it. I've flown mine in winds upwards of 25 mph. But then, I fly my UMX Radian in winds over 15 mph.

[AkumaZeto]

I can handle the wind it just becomes more work than fun. I dont like watching the wings flutter and dip all over. I am no expert either dont get me wrong. But to much wind is not much fun for me. Thanks for responding though. Not many people are so that must mean not many owners.

The zero is terrible in anything over 2-3mph. Just all over the place. The corsair as well but I think thats the shape and the lack of power the stock setup offers.

[xviper]

This is not a "cheap" foamie. Perhaps that's why there aren't as many of them out there as other more popular models. Mine came in at over $700.00 CAN. It's a great plane, but it's a lot of money if one were to have a mishap.

[AkumaZeto]

Well for the cost I Am considering the v4 fms and then I have monies left over for the Bearcat too

I was lucky enough to buy the CZT28 when HH offered the 10% rebate, and I am thoroughly pleased with it. As xv2 states, it flies like a docile trainer, or hot, if you pour on the juice. I am using BOLT HVLiPo 5400mah for battery, and get 7-8 minute flights with about 3.8v remaining. There are several postings about the delicate foam hinges on the flaps, so I added flat ca hinges ca'd to the bottom surface of the flaps without cutting the sealed foam hinge apart. This maintains the air seal across the flap span, and with a full flap landing, it touches down lightly at surprisingly slow speed. I fly from a grass field, and the plastic tab on the gear strut which holds the wire closure for the strut door snapped off due to the gear flex on taxi. I was able to ca the tab back in position, then used microfiber filled epoxy to build a fillet around the tabs, which has worked well so far. I think this is a fine design done well, and I'm glad I added it to my collection.

Exact same situation for me. I've glued that tab back on twice now and it just won't hold due to the extreme roughness of the field. I even drilled a hole in the tab and wired it around the strut. It still broke. I was going to just take the door off both sides and leave it. Then I decided one last go and used a tie wrap around the strut, drilled a hole in it to hold the wire end on. So far, it's held. Funny, only one side has done this. The other side seems to be stronger.
BTW, check the gear door at the other end. The repeated bouncing has caused the little frame that the door pegs fit into has started to crack. I removed it and CA'd the crack and put some thin tape on the underside of the crack to help it stay together. Also, one of the door pegs actually sheared off. I replaced it with a CF rod (a bit longer). Those struts really move around a lot on rough ground.

[CZ Flyer]

removed the gear doors completely on mine due to grass, still looks great in the air.

[AkumaZeto]

Are there beffy retracts that can be put in? Eflites with robo struts?

Not sure. I ordered an oleo nose gear for mine but the spring is way too weak even after upgrading to a thicker one. It had enough strength to hold the nose up while stationary, but as soon as I applied full throttle for takeoff it folded under and the plane started cutting grass! Went back to stock for now.

[VOODOO]

The struts on my CZT28 are fine, and hold up well on our grass field. The only problem with the landing gear has been the plastic tabs formed over the wire struts. The fix I described earlier seems to be an easy and effective fix to the broken tabs.
