Yes, definitely at that joint. It's possible that the gluing process isn't really great, the starboard wing wasn't really damaged, I just reglued it but added a CF spar. Of course the port wing will take a bit more repairing.

I would recommend reinforcing the joint but that's not really possible without removing the covering film.

It does fly nicely but it is defiantly limited to a 3s 2200, it can't really handle any extra weight.

UK finally got a break in the weather and I managed to get the first flights of the Dragonfly in. Despite what was said in earlier posts the thrust from the NTM 2836 on a 10x6 was more than ample for the climb out, why would you want it climb faster than mine did today. It needed a lot of aileron trim to fly straight, the original twist in the fuselage may not have been totally cured. It flies OK, need to see what it is like in a thermal. I must admit that I have had better experiences with a new model. To be honest the fact that Hobbyking supplied the model with a twisted fuselage has not helped. Then they have compounded the problem by ignoring my request for assistance with the problem and then finally doing absolutely nothing about solving the problem. OK Hobbyking's prices may be low but no customer support when you need it is not good.

I also flew my trusted Valbella which I have just converted from brushed 600 to a brushless Turnigy Gliderdrive 3850 3.5 960kv. A good day.

Actually,the problem tail is a beautiful trouble
I am still assembling my model,correcting and improving the various errors!
Certainly not recommend it as a first modelview also the bad after-sales service....
Have you checked the incidence of motor 2-3DX and pitch?

Got another good break in the UK weather and got 20C in London. Wind a bit gusty but Dragonfly flew nicely with a couple of clicks of down trim for the wind.
Once again it climbed strongly on the NXT 2836 and 10x6 combination. The model feels very light at launch and in the air so hoping that it will thermal well, it can certainly turn tight.
Nice to be getting something back from it after the troubles it has had.

Have you been flying Andy?
My Dragonfly is coming back together nicely, wings and fuse are pretty much together now, just a bit more strengthening then I'll cover the wings and place the motor. I'm looking forward to getting her back in the air, I'm hoping the extra strengthening will help. I also plan to use a smaller 1600 3s battery, I hope to shave a bit of weight off the 1000g I had.

I do not think to repair,the fuselage is cracked and the wings would to reinforce
and repair. Too bad because I had set really well!!
You should redo the wings from zero,they are too weak.It happened in a steep turn,which I considered a normal curve

No problem with keeping the wings together but you may have a lot of problems keeping the wings straight, they have a tendency to fold on this model. Fly it gently, no aerobatics or hard turns!
