Ive just gone by the plane being physically level to the ground. Im not positive on what actual physical parts should be level though.

I think the batteries are physically the same size, it just seems that the original has a foam wrapping under the heat shrink, and the Blue Lipos are just bare cells.

Ill weigh them later tonight and let you guys know whats up.

Mine got its maiden flight this evening in calm winds and 30 degree temps. It felt a bit tail-heavy, so I'll move the foam lipo 'shims' to the rear of the pack to shift the COG forward for the next time. The flaps worked GREAT where I set them, and they still have lots more addional throw. I took off and landed twice, about 5-6 minutes total flight time. I was impressed. This is my first larger plane, and so far I'm happy with my choice.

Earlier today I cleaned up the slop where the quick-connects meet the control horns. The holes are slightly over-sized, leaving some play in the horns. I hardened some CA in the hole, then re-drilled it for a better fit. I also did the "cracked CA" method on the flap horns with everything already assembled, and was able to remove a lot of slop there as well.

Dynam Cessna 182 Plug-and-play airframe with motor and servos: $120
Spektrum AR6200 receiver: $80
'Blue' 2200mah 20c lipo: $20
two cheap micro servos for flaps: $0 (harvested from Walkera helicopter)

In my case, it's basically a $200 plane. (plus a few bucks of tidbits like wiring and flap quick-connects.) Heck of a good deal for anyone else starting out. I'm excited about this season.

It had a tendency to climb and stall easily with the elevator surface adjusted straight and neutral.

I used +12% down elevator with flaps "down." Seemed to work OK.

I'm really disappointed with this plane. I've worked with it quite a while; changed motors, adjusted control surface throws, experminted with different CG settings - and still it's just not a very good flyer. It's not stable in flight, requires constant changes in trim, and still feels sluggish.

I've had several other Cessnas by Art-Tech, ST Models, Airfield and Hobbico. All of them fly better than this plane. Each has some strong and weak points but overall any one of them is more pleasant and fun to fly.

I really wanted to like this Dynam as I have 5 other Dynam planes that all fly nicely.

To all of you who are using this as a trainer, I would say that other models will be easier and much more fun to fly.

That's strange. It can't really drift out of trim unless the battery is shifting or the wings are warping during flight. I'll have to pay closer attention on the next flight...

Planes can easily require different trims at different power levels and with different wind conditions. But it's more pronounced with this Cessna than others.

Even if the prop thrust angle is shummed/adjusted?

(sorry, I'm somewhat new to this)

AC adaptor is included.

I got several more flights on this one today, now have logged 24 - it's an OK flyer but I still think others fly a little better. It does look very nice and handles a little wind with no problem. It represents pretty good value for $139 RTF.

I came up with an improvement for the poorly-supported nose wheel,

I already added a thick spring on the metal shaft to make it stiffer so it won't bottom out as easily. Yesterday, I added support where the nose LG comes through the body between fuse and cowl. I found a thick plastic sleeve, drilled it out to the correct ID, then sliced it into halves with a razor blade, placed the halves on the strut, and carefully glued them back together. Then I Gollilla Glued the re-assembled sleeve into the hole in the EPP. Now it's super stiff, doesn't wobble around, and doesn't stress the attachment point inside as much.

Very similar to the solution I used and described in post #31. I just used the back half of the sleeve and glued it to the fuse.

My solution is easier but your's is probably stronger!

do you guys think this is a good first plane for a beginner who's been flying in the sim for about 3 months?

I don't see why not. I got started flying Parkzone Ultra Micros, and this plane seems much easier and more stable.

dbc, I see your post about the half-sleeve now. Your solution allows for easier cowl removal without cutting. I managed to eliminate nearly ALL of the play in the wheel this way-- hopefully I don't need to get at the motor anytime soon...
