Default Eflite Fokker DVII 250 build

I started my Eflite Fokker DVII this week-end and was wondering if anyone else has built this one yet? I am close to the point in the instructions were it says to add the thread through the cabanes and struts. The wings feel plenty strong. I made sure the re-inforce them with extra CA and it feels much stronger than the Nieuport 17 does. The wing's foam looks to be cut a bit thicker as well. I'm not sure what the thread does for this plane as in the N17 where you had to add dihedral; this one isn't like that.

Update: After watching the Eflite preview video again, I guess the thread does provide a little uplift to the wings for a bit of dihedral.

I do not have the Eflite DVII yet. But if I were doing it I would not put brace wires on the plane. The real plane did not have them. I would run a CF rod on the under side of the wings just behind the leading edge to keep the wings stiff. My Eflite 17 had a crushed wing(I bought one with shipping damage) and I put a CF rod on the wing. The wing is really stiff now.

Hey thanks Degreen, you know, the wings on this one feel a whole lot stiffer than the N17. Wish someone else would be the "guinea pig". Hehe...

I still haven't had a chance to fly this one but I pulled out the GP CG Machine to check it since I didn't trust my fingertip method. It was still tail heavy at 2" from LE, so I had to add 3/4oz of lead to the front even after putting the 2S battery as far forward as I could get it.

Looking good! Hope you have less wind than we do here - get it out and in the air if you can.

It was windy here too, but died right at sunset... I didn't try it yet as it's supposed to be nicer tomorrow. I hope it flies better than the Eflite N17. I thought I had it balanced right but it still flew squirrely like it was tail heavy.

I put 2 of the Eflite N17 together and both flew great. I can fly them around about head high and just float them in for landing. I used pull-pull for control and mounted the servos behind the firewall. The balance was perfect without adding any weight. The one I made into the Flying Fish is probably the plane I fly the most. I did add a bamboo skewer to the bottom wing to keep it from bending between the fuselage and the wing strut. CF would be even better.

Well, I went out around 8:30 this morning and finally maidened the DVII. It flies so much better than the Eflite N17 that I have. I am really happy! Two great flights and landings. It will even loop while in level flight with a bit of throttle-up. I ended up having 1/4 oz of lead in the nose and pushing the battery as far forward as I could to get the 2" COG.

I hope to get a video soon but unfortunately it will take another week to get the chance to try again since it's dark when I get home from work now.

Great plane! Looks like she will really fly slow. Good camera job too!

Excellent Indy! I have both the N17 and the DVII on my wish list. I'm more inclined to get the DVII now over the N17. Thanks for the video. Nice job on the landing BTW. marty

I have the Jenny and the Nieuport 17 flying. Both are great floaters. I am working on the SE5A. Want to get the DVII. When I get the DVII I will not use wing brace wires but plan on using CF arrow shaft split into 4 pieces to keep the wings from bending.
