I put the Fokker in hard yesterday, bashed the nose in quite a bit. I've begun repairs, hopefully it will be ready to fly again by next weekend.
I know everyone likes crash pictures, so here they are. The final 2 are the progress I've made on repairs.

Wow, that's some carnage, but I'm very happy for you that the wings were spared - they're so much harder to repair and still have look good.
Any idea what caused it? No matter what it was, so many of us can probably relate!

I've flown it 3 times, moderate damage on the 1st flight - 45 second flight ending in a crash, 2nd flight went much better, I hit LVC and had to glide in, just bent up the landing gear a bit. This flight I was near the end of the battery, landed once. I decided it went pretty well so I took off again to do another landing and got mixed up too low to recover.
There is a reason they had cemeteries next to the training fields. This is my 1st alieron plane after learning on a Super Cub. I'm still getting the hang of it, I suck at coordinated turns, I can't keep the throttle steady while using the rudder. Thankfully these Electrifly planes are so much sturdier than the old guillows planes I used to fly control line with my dad as a kid. A guillows plane would be a pile of sticks after a crash like this.
I have found a good way to fix the interplane struts when they break though. I glue them back together, then wrap the broken area tightly with thread and cover the whole wrap with clear dope. I've broken the same strut twice, the second time right next to the 1st repair. In this unscientific test I'd say the repair is at least as strong as the wood is alone.

Oh boy, I sure remember the 1st aileron thing, seems like yesterday. I've only been flying since '07. That whole concept of banking the plane, and then "UN" banking it, well, it was a challenge!
I know some don't like it (feel it's a crutch), but I really enjoy using mixing on my radio. If your radio does mixing, it's a lot of fun to use. I've linked my rudder to the ailerons. It can be turned on and off by a switch. Turns are very "pretty", and it really helps in a jam with these biplanes.
I equate it to learning to drive a car with an auto vs stick. Learn the act of driving first, then learn a stick (again some will dis-agree).
Oh, one more thought. If your radio allows it, you can put more tension on your throttle movement, and less (or keep same) on your rudder movement. (talking at the transmitter). This will keep the throttle from moving as easy when using the rudder.

I've got a DX5e, so no mixing. I took my driving test in a manual, so I guess I'm destined to do things the hard way. I guess it's not really a problem, it's just good I like the building (and repairing) side as much as I like to fly.
I feel like a neck strap might help so I don't have to hold the TX while I control it. I might be able to use the sticks more precisely then.
Thanks for the encouragement!

No big deal really. I knew when I bought it I was going to crash it, but I went agaisnt conventional wisdom and skipped an alieron trainer. I was confident enough in my re-build skills to take the risk. I just have to avoid a real hard hit where it isn't fixable (and then I'll send it to degreen - shiping will be nil, it will fit in a shipping envelope)
It's fun to be a second from disaster the entire flight. Makes the battery seem like it lasts a long time.

I have forgotten how many times I have rebuilt the wings, front of the fuselage, and landing gear on my GP SE5A. I still loose track of which way is up sometimes and that means another rebuild. Send me the DVII, it will no long look like a GP plane when I get done with it.

I have my next foam scratch built almost done. I will post pictures as soon as I get it painted. It has passed test flights. It is a model of a very rare WW1 era flyer that flew out of the dark forest and was thought by both sides to be a secret weapon of the other side. Both side shot them down till there were none left. Only rumers tell that it even exsisted. I found a paper model on the net that I modified into flying model. I will post pictures and tell more on the WW1 thread in a couple of days.

I've seen some of the odd Fokkers, but I really like the look of the D.VI. If you have the money a D.VII and Dr.I kit bash would be sweet. Then you could make triplane with the Dr.I wings and the D.VII fuse to really mix things up...
#215

CJ,just a thought,when I rebuilt my last DV11 I canned the stock battery tray in favor of an angled bottom load. The batt. slipped right into the fuse behind the motor. So I tilted the batt. a bit rearward so the bottom of the batt sat touching the back of the ply the motor is attached to and made a balsa brace the top of the batt. touches.Put some velcro where it makes contact and its much easier to change batts,you dont have to remove the cowel .The biggest thing was when I did the CG over,it needed an ounce and a half less lead to balance.I guess if you were looking at a cutaway view of the fuse from the side,the batt. would lean from the 7:00 to the 1:00 position. Just a thought. B

From the picture it looks like the top of the cowl is good. That is the part of the cowl that has rounded part. I think you can make the rest of the cowl using flat plastic and screen wire.

What motors is everyone using in the DVII? I'm looking for one from hobbyking but all the motors I find have four mounting holes instead of three like the Electrifly recommended Rimfire 400. What are my options here? Which is a good choice from hobbyking?
#219

2830/09 from Heads Up RC, Ive got three of them in my EFly WW1 fleet. I have two of the Rimfire motors also and I dont notice any difference in performance plus at less than 1/2 the price and $2 shipping its a no brainer.Contact Scott at Airland Hobbies and ask him for the motor adaptor,they are cheap and save a bunch of time not having to make one,unless you like to tinker.B
#220

I have a 2410-08 from HK in my GP SE5A. Use a 9X7 prop with 3s and it flys great. Had to make a new mount to hold the motor.
#221

What about this one? It's the same dimension as that Rimfire 400 (28x30) and approx same kv and watts.

I have some motor mounts on the way from airland hobbies to mount a standard 4-hole motor

I was ready early this morning, so I figured I’d take my Fokker out for a flight before work. It was dead calm. I got some good flying in, but then I got too high and lost orientation and before I knew it I was in a spin. I panicked and just mashed the controls. It was a BAD crash. I’m not sure what I’ll do. I may have to buy a new upper wing, it is really smashed into sticks. I’m thinking it will get put away for a little bit until the sting wears off. I took a few pictures of it loaded in the car with my cell phone. There are lots of little pieces in my equipment box next to it.
With so much damage, I may try to make a more scale front end because I'm going to be rebuilding the whole thing anyway. Although, with crashes like this there doesn't seem to be much of a point in that!
