Default RE: BUSA Fokker DVII

Asked a bunch of guys questions and got lots of good answers. Thanks guys. About ready to maiden next weekend. Hey,, I had to add 3 1/2 pounds of lead to the nose to get my C/G correct. The total weight of this plane is 23 1/2 pounds. Sound about right? And Thanks again for all the help and great information I got from this thread.

23.5 lbs should not be a problem,that's about what mine weighs.Proctor DVIIs have been flown at up to 28lbs.

Good luck on the maiden.

The maiden went very well this morning. These fly fantastic! I didn't add the 3 degrees of positive to the elevator and needed to add some down trim to fly it level. Not enough to remove the tail feathers or anything like that. It flew great just like it is. Here are a couple shots from this morning. Ron showed up a 6:15 AM with the skulls. One of the skulls would not come off of its backing paper,,,one was better than none, he will make another one today and bring it over here or to the field in the morning.

The skull is called a Totenkopf.

The plane looks awesome, congradulations and many happy flights to you.

I used the AX 5330/24 on 10 cells,8000 mah lipolys from TP. Swinging a 24/10 prop and using(the first attempt) a Jetti 77 amp
ESC. The bench test showed about 68 amps so I figured the 77 amp ESC would be fine as I did not intend to do much full throtal flying anyway. As you can see in this clip I did not account for the Fokker D7 having more drag than I had figured on. Causing more of an amp draw that I had thought. After about 4 mins as you can see in this clip I had a dead stick on my hands. No damage but it sure looked bad. I guess you never stop learning about your hobbies. Oh, I now have well over 6 flights on her and no more problems as I now us the 99 amp ESC.

I asked them (Balsa USA) the same question almost a year ago, and they said it was a fact. I guess I can send them an e-mail and ask how it's coming along...

Bladerunner. Liked your video, and the plane is great too! Sorry to see you had an incident so early in the test flying . I had a rough landing due to some overly long grass, and a slightly nose heavy condition.. But I survived as well.. Hope you get as much fun from flying it as it appears you did from the nice build!

Had a brief chat with D Johnson at Scale Masters Nats in Sarasota and he confirmed that BUSA was working on kit development of his Albatros design. There apparently are some hurdles to jump getting this into marketable kit form, but keep fingers crossed...........John

How is the best way to go about getting the plastic chin to fit well? Or is it better to toss it out and build something myself?

Jeff, if I was going to do it all over i would build the chin very solidly with wood, because you will almost definately need some lead up there,and that would be the best place to put it. If you are like me you will need more lead than you had even considered. Any weight in the chin part itself won't hurt so make it strong enough to take a nose over...

Nose overs.......I guess a plastic chin would not be the best thing to have if that happens. I guess I will start chopping a wood part. Thanks.

There is a fiberglass version available from fiberglass specialties. Also, I have nosed mine over many times. The item that takes the pounding is the top portion of the cowl. Not the ABS chin section. Actually I built mine stock but fiberglassed the inside and have not had much trouble with it.
If you want a modification that will save you from nose overs, Get yourself some 1\4" music wire and use that as your main axel. The wire that comes stock bends and flexes too much. All of my landings have been perfect since I did this mod. This includes a perfect "10" score on landing at a scale masters qualifier last summer.

Thanks for the information. I will look them up. I have looked at your DVII many times in the building of mine. Yours is a true thing of beauty. I think you mentioned in a diferent post about the 1/4 inch landing gear. So I have already put that up-grade into my plane. I also replaced the wire tail skid. I just shook my head at that thing that came with the kit. Do you think it flies as good as others have said? I sure hope so. Again, thanks for the help and another picture of your nice birds.

Yes, the DVII flies wonderfully. To be perfectly honest, I would put a bigger engine in mine if I were starting a new one. I have a G-38 and I am running the stock muffler. It is just enough to fly it at my altitude (5,000'). After entering mine in scale competition, I would like to have it overpowered to help with executing some of the manuevers. I would go after a DL 50 honestly. You can always throttle back.
A couple of things on set up, have as much aileron travel as you can get and do not use differential. I had mine set up exactly as stated in the manual and there was not enough to execute a roll. With all of the differential they ask ed for, it killed the overall effectiveness of the ailerons. I have not experience any large amounts of adverse yaw and I like the way it flies without the differential.
Have some toe-in set in your gear and you will have uneventful ground handling. You will be very pleased with your plane and try not to be nervous about the maiden. It is a very smooth stable flying plane. Couple of more pics

That is a real beauty! Do you know how many hours you have in it? I could only dream of getting half that detail. It's all I can do to build straight!

Oh.. the how many hours question! Honestly, I only keep track of hours when I am getting paid. Since this is my hobby I really do not pay much attention. Lets just say it took a solid year. I have gone back and added a great deal of detail, mainly as I decided to compete with her. I am now really fascinated with competition scale and have my next project lined up. A 114" TA 152 German fighter. All I can say though is my Fokker DVII would not be anywhere near what it is, without all of the great help I have recieved from this website. Almost everyone in here is great and I am truly greatful for all of the help.

I'm just curious how I can get toe-in on a WWI model with single axle, particularly if that axle travels up and down on a bungee.

On mine, I have music wire running the width of the gear in front and back of the axel. This was to support the axel wing and bungee supports. Then in the middle of the axel, I pulled it back and lashed it with wire and soldered it to the rear piece of wire. I am sure I am not describing this well so I will try to post a pic. These pics are from my triplane. I have mentioned several times, I started out with bungee gear but have since made them solid and upgraded the axel to 1\4". All is well now. I did not like shocked gear on my WW1 stuff. Too much weight above the vertical CG.
