I really enjoyed this plane. So easy to fly...Probably pushed her more than she wanted me to but accepted it with grace. I would love a larger scale version of this model.

Hi Aros, I had one and put in a CF spar. Did great aerobatics (but not scale although I did see a full size 310 barrel roll once.....) and the wing didn't flex at all. The only thing I wished was for a short nose version (earlier model C310) since I really like that one.....

Now I'm considering building my own but in a UMX size.....

Here I copy my DGC review:

"04/10/17


Very disappointed with the DGC I received

I read many DGC reviews, most of them good, and I am an experienced RC'er and human (64 years old) and I have to write this, although I hate to complain. I was very impressed by the fast free shipping and my good impression continued as I unpacked my airplane. Each component was in its own box within the kit box, and cushioned well with paper packing. My expectations ran high, but when I lit the electronics up for wiring , servo centering and general testing, the problems began. Motors wouldn't spool up. Then they would. Then one would and one wouldn't! I had to fiddle with them for 2 days, and as of now, they seem to be ship shape. But I have no idea what the problem was or how I fixed it. Then the landing gear wasn't right. Seems to be a gremlin in the right main. I flip the switch, the nose and left come down, the right stays up. It isn't hung up on anything. It just sits there! Then I discovered that anytime it doesn't come down (sometimes it does!) if I touch the rudder stick it comes right down! That's not right, but as long as I am pretty sure I can get them all down (BTW, it ALWAYS goes up!), I'm not going to mess with it.
Now, as if that wasn't enough to drive a man crazy, I found the servo arms for the tail (ie: the rudder arm and elevator arm) were mounted on the wrong servos.. OK, easy fix, right? Not so fast! I mounted the arms on the proper servos and found the pushrods to the elevator and rudder were each about 1/4 inch too short to reach their respective control surfaces! Yes, the servos were glued into position with the output shafts closer to the nose, and therein lay the rub! The servos had to be mounted with the output shafts toward the stern or the supplied pushrods were worthless! It was NOT an easy job to dismount those HOT GLUED servos from the foam, and after they were loosened up, they still would not come out until I wedged the fuse open about a half inch (praying I would not hear the crunch of breaking foam!) Finally, tonight, I think I have everything working. The airframe is assembled, the motors seem to be working the way they should, and the gear is working albeit with the aforementioned glitch. I had hoped to maiden it today but such was not to be the case. If it flies half and nice as it looks, I'll be happy, but Motion RC, you should put a 50 dollar credit in my account for the hassles I had! You should also check into the boxes of other DGC's from the batch mine came out of because if they all have the servo problem, people are not going to be happy. Hopefully, mine was a one off.

BTW, one last thing, if you use the supplied tape strip on the nacelles to mount the cowls, and then need to service the motors, you are going to be in for a tough time. I used the decal on the outboard side and some cellophane tape instead. This way, if I ever need to service the motors, a quick slice with a #11 blade and off come the cowls."

After posting the above review, Motion RC reached out and tried to be helpful, but really, what could they do? Ultimately, I was able to address all of the issues, but for me, what should have been a pleasant 2 hour assembly turned into at least 10 hours of hair pulling frustration, and I even tried to hook up the lights, but found only ONE of the three would illuminate.

This was for me a plane that was headache after headache. I had finally gotten it ready to fly back in April, and then when I checked it out I found it had a broken rudder control horn! Disgusted, I put it on a shelf and left it there for a while, until recently when I decided to fix it and try once again. Today was the day I finally got it to the field. And true to form, the problems kept coming! I attached the wings at the field. Before screwing them down, however, I connected all the wires. 1st off, the motors wouldn't spool up! I think I had the wires right. Everything else was responding, even the previously balky landing gear, but I had to fiddle with the motors for 20 minutes before they started working. Finally!! I thought! Put the plane on the ground and tried to taxi it, and found out that the nose gear and rudder which operate off the same servo were reversed, so left rudder on the ground produced a right turn, and vice versa. Talk about frustrated! I walked away from the plane and sat with the guys for about 10 minutes. Then I went back and looked it over. There was no way to fix it at the gear itself, so off came the wing so I could access the servo. The only option I had was to get BOTH pushrods on the same side of the servo. Moving the nose wheel pushrod was impossible, but I was able to move the rudder pushrod over the to wheel side, make a small adjustment at the rudder, and viola!, problem solved. And Hallelujah, after all the grief, the sucker flew great! Did not need much trim. Power was plentiful on a 3 cell 2200 which as others have noted was a very tight fit. Wheels went up and down on command, and the landing drew applause. So I am pleased to be able to say it flies very nicely.

I have read ALL of the reviews on the product page, and noted that there are several which make mention of problems like mine. Yet the overwhelming majority of reviewers state that plane went together quickly and without issue, and flew great. But my experience shows somewhat differently. I hope that hard part is behind me.

I now have 3 or 4 flights under my belt, and I am pleased with the way this model flies and handles. One of my flaps broke free in flight and fluttered down to the runway, and it seemed to make no difference in the flight characteristics. I stuck it back on with some tape, but on my next take off (bumpy grass field) it fell off and I didn't even know it until one of my club mates walked up to me with it in hand while I was still flying! Anyway, I decided to do the flap install. I have plenty of spare servos and a 7 channel computer radio so I didn't need a reversed servo. I used the supplied hinges (they look so cool!) but was scratching my head when I realized the center hinge and the servo were in a line and there was no provision for mounting the control horn. I solved the problem by using the connectors on the servo and the Z bend at the control horn which I mounted along side the center hinge. I did find it necessary to use the outer most hole on the control horn on the flap to avoid the problem with the geometry of the hinges, and I am looking forward to giving them a try next outing.

Hey guys, I was wondering what rates do you have set for the GC? Just curious to see what all you are using.
