dp ultimate 40
 

:eek:Have dp ult. 40 and it has been flown several times. Had to add about 4-5 clicks of up elevator to fly and glide level. Balance ok according to instructions. Anyone else have this problem?

Sounds like your incidence is off.

Hey, I am ordering one of those planes. What engine do you have. How does it fly. Is there any building tricks that i need to take note of before i start this plane. Im going to use a OS.46fx. Also where did you order your plane from. Any other info would be great.

I didn't know they where still around to buy!!

I bought mine in the fall of 2002 from Cheif Aircraft...but they no longer sell DP products (hmmmm I wonder why [:@] Anyhow I've just put a handful of flights on it since I got it....The YS 63FZ I've had on it has been very unreliable (first 5 where deadsticks) and fickle.... It would run flawlessly at my house....but in the air it would always die....Anyhow, I've finally got it to work reliably, and I too notice a couple clicks of up with it balanced by the book... Next time I fly it I'll move the battery a little further back as I can tell it's nose heavy....I want those flat spins flatter, and better torque rolls...But damn it's a fantastic aerobatic plane.....It's by far the best knife-edge flyer I've ever had! It's a quick little plane that keep you on your toes when ya fly it!!

As for things to do when you build it, Deffinatly make a hatch and plate to mount the elevator servo under the cockpit (much better pull-pull geometry). I'd also reccomend instaling the engine inverted (something I wish I did, but next to no chance of getting another cowl I'm having to live with it mounted on its side. Inverted will give you better engine cooling and better balance from wing tip to tip) Here's the link tho the RCU review on it: http://www.rcuniverse.com/magazine/a...?article_id=49

Mine has a couple clicks of up especially after the plane was disassebled and reassembled last year to replace a servo. My guess is that the incidence is off and you would need to adjust it to flatten out the elevator. I never bothered to fix mine yet though as it doesn't bother me other than looking at the elevator being a bit up when in "neutral" on the ground.

Definitely check out the review in the RCU Magazine I did on it. I had a Saito 72 GK in it which I felt was a good match. A YS 63 is also a good match when you get it running right.
