Thanks for all the input guys. This will be extremely helpful when it comes time to release the V4(kraken?)

Sounds like a personal problem, muthafukkkkkahs!
I'll see if I can make time to fix the h-stab on my Evo540 for some abuse at BeaverBro… They're all different birds, but I'm interested to compare an EvoEdge to a GoofyEdge and maybe a RadYak in the mix too…

I freaking love mine it just couldn't get any better. It's a true 50' slab. I would buy another right now.

I dont have much stick time with the EVO Cap, but the original MadCap did inspire me! Thanks Ian :rockon:

Its amazing just how different the goofy edge is to the EVO edge. I flew them both over the weekend and it was surprising just how different the performance was. I love the goofy edge but what a different machine!

I flew both too... Radically different! The Goofy Edge kept its ailerons in place and utilizes composite laminate building materials! WAY different from an Evo540 in my hands! ;-)

So in other words when crashed onto a wingtip you have to replace bits of aileron with cardboard instead of gluing in new hinges...

:P :twisted:

Incidentally does this mean that your new standard of testing is a cartwheel dork on cement? I may have to rethink letting you test out my planes :D

Them flat rate boxes ain't no joke, got me thinking if one could build a slab with minimal balsa and a tube and the rest cardboard, if one where so inclined. Not sure how the weight penalty would be though.

Pretty bad. I've done some testing for weight of non-conventional materials thinking that cardboard could be an interesting building material but balsa trumps it for volume/weight.

With first hand experience I have to say this is my honest opinion

No slabs were harmed in the making of this video.

I flew mine about a month ago. CG was about 7.5" back from the leading edge, but I tried it anyway. My setup uses standard size servos, Hacker motor, Talon 90 ESC and 6S 2600 mah packs. It had good power, but was very pitch sensitive. The flight ended after about 3 minutes when the elevator servo died and caused the plane to lawn dart. Fortunately the ground was soft. The only damage was broken prop and crunched LE between the last two ribs. This must have been from fuselage flex. The plane was nearly vertical when it stuck in the ground.

I wanted to change the CG prior to flying again. I moved the motor forward about 3/4", moved the rudder & elevator servos forward about 4" (they just miss the ailerons now) and installed a little heavier wheels. These changes only moved the CG forward about 1/2" but this made a world of difference in the way it flies. I flew it 4 times today and complained when my "fun timer" went off. I have a little tweaking to do, but overall I am very pleased with it.

Flying weight is 4 lb 14oz.

The wing design on the cap is fairly sensitive to CG changes and it sounds like that bit you. I hear people say all the time that "aft CG is fine for 3D" and it makes me cringe. Dial that sucker in to a nice neutral balance and she'll treat you well!

Just curious, why does that make you cringe? When flying 3d we are mostly off the wing for the most part. Most 3d maneuvers have a nose up attitude (since the prop is keeping us in the air) a little on the tail heavy side just helps maintain this and the added tail authority is a benefit. No?

CG on my Cap is 6.5 and that is neutral upright or inverted. Cap seems to have plenty of tail authority in my opinion :tu:

No.

An aft cg does not increase tail authority it increases tail control sensitivity. A cg that is aft of optimum, creates an unstable condition. An unstable aircraft is unpredictable, wanders and causes the pilot to constantly chase it with the sticks. Some skilled pilots with fast reflexes might enjoy the challenge of doing this but most want an aircraft that goes/stays where it is wanted.

An aircraft is never truly "off the wing" even in a hover the wing is needed to stabilize the aircraft. Try flying a plane with a really short wingspan and see how well it works.

Interesting info. Im not expert for sure, authority/sensitivity, sounds very similar to me. I agree that it can create an unstable condition (tail sensitivity/authority). I agree a plane is never off the wing, but there is a big difference between flying around straight and level, and 3D (at least that was the point I was making). It comes down to personal preference I guess. IME I dont care for planes that point at the ground often. A CG towards the aft range usually helps this (for me).

Everyone has their preference. And just to clarify, this has nothing to do with Ian's edge :drink:

Mo actually encouraged me to fly his EVO Cap at BeaverBro :clap: First impression was the entire slab is hella stable, as far as no flex anywhere, huge flight envelope, will do anything you ask, and performs amazing walls :drunk:
Mo is a bit of a perfectionist, neutrally balanced, strong swervos with a piped OS 75AX on the nose :banana:
Wicked combo, thanks Mo :drink:

I agree. When I first started 3d I liked my planes tail heavy. It was mainly to help learn HA maneuvers and hovering. Now that I've gotten a little better (not much) I really like my CG's at neutral. I just seem to have better control over the plane.
