Another question guys, If I were to scratch build this plane how many pieces of depron will I need? Looks like it is broken up length wise. Does this mean I can use the 27.5 x 19.5 sheets from Grayson or do I need the full sheets?

A single full sheet is best. Then you can cut out the main body as a single piece by placing it diagonally across the middle,and then fit the other pieces around the edges.

Darrin:
We were only using the 2200mah in the static tests. In flight, we are using 3s 1550mah 30c. However, many folks are using the 2200's in flight. It does appear that this 28" wingspan can handle the extra weight...although the flight characteristics will change at least slightly.

I agree with Harrow. A single full sheet is best. The sheets I am using are ~32x49. If that isn't feasible, you can get away with using smaller pieces by gluing them and reinforcing them with the carbon and epoxy method...but you will end up with a heavier plane.

This plane can be built with a 39x27.5 sheet, and a 39x13 sheet. I cut the main body out in two sections, with a "V" cut from the wing break back towards the motor mount.

I have flown my 100% with both 1350 and 2200 lipos. Performance is about the same with both, but a little more duration on the 2200.

I have the 100% and the 130% version of this plane and they both fly great. I keep hearing about the 66% version. This sounds great for one that I can keep in my jeep. I have searched the thread but can not find a tiled pdf for it. Does it exist? If not could someone post it please. I have not figured out how to resize the orginal pdfs yet.

Can you point me to the 130% version? Would that be a 36" wingspan?

See post 1404 for a link to a build thread with plans for a 66% plane.

1300 or 2200 ?

You do less damage when you crash with a 1300 compared to a 2200.

Now a question to toss out there... have any of you got your raptors to hover, the guys with ailerons probably have - My raptor hovers like a 2m long IMAC plane, with spoilers on.

I want to know if hovering or high alpha is something raptors are unusually good at, or do most deltas possess this ability?

High alpha, definitely. Hovering, not usually...not to my knowledge. Let's see some vid.

Mine does a great extreme high alpha, but I've never been able to hang it. If I get it pointed straight up, it usually winds up flipping over on itself in about .5 seconds.

My F-16XL can just about hover straight up though.

Maybe not a 'complete standing still' hover but I defiantly have had it almost 90 degrees for a few seconds, yeah high alpha seems to come stock in the F-22 package!

... I thought about having a delta that does jet-plane manoeuvres at the same level of 3D planes, capable of extremely low speeds - possibly leading to a Cobra! (the holy grail)


I may just have to get a vid, I'm in the process of re-covering the plane though, so maybe next month.
