Hey guy's the Slick is finished but I need some feedback regarding the balancing. Using the method of hanging it by the spar tube the nose dips about as much as it shows in the manual (gas tank filled). Because it was coming out nose heavy you can see how I put everything towards the back. However when I try double checking by suspending it 4-5" back on the wing tips it appears tail heavy. Which method should I trust?!

(BTW, a shout out to Cry for giving me a bunch of the braided wire cover, it's excellent at protecting the wires from chafing!)

I thought I'd stop by to ask this question... might be a longshot considering the location, but a friend of mine has a son in the Nevato, CA, area who flew years ago (he's probably in his mid-40's now), then got into racing cars (full scale), and how has a young family and is looking to get back into flying. He's interested in the 50cc - 120cc size 3D/extreme aerobatic airplanes and I'm trying to help him find a club that's 3D-friendly in northern California. I'd appreciate any help you can give me.

Second, I finally got around to getting the Javascript done for the PropEngine, so it's back up and has a new home: http://rcwebclub.com/PropEngine.aspx

Considering there is a whole state + (~800 miles) between us here in Seattle and Novato, CA, I'm not sure you're going to find any assistance from this group.

Good luck though.

Yeah, I thought it would be a longshot, but if anyone knows of guys coming up your way, like for IMAC competitions, Huckfests... I think a few guys come up from as far south as San Diego for events... so maybe someone from the Bay area, or Sacremento, knows of a club. Thanks, anyway.

i would start by putting the canopy on. that would make a difference. and ive always measured from the wing tips. not sure if it makes a difference

That's what's confusing. The manual says it shouldn't be different but it is. I'll put the canopy on and use the wing tips. Thanks!

The Slick looks Beautiful Joe.

I don't fly gas but I have always had the best luck measuring CG balance with the plane set up to fly. As Harv indicated canopy on, in my case measuring at the wing cord at the fuselage root using a cg machine/tool. I then separately measure left / right balance using a piece of string attached to the freely rotating nose cone & and looped around the tail section behind the canopy.

Then the real work begins when I start flying as I then dial in the CG, setup & trim based on my flying style, following a specific flight test protocol. Here is a link to a great examplehttp://trabucorcflyers.com/uploads/T..._RC_Flight.pdf

Throughout last year as I pushed myself into new & unfamiliar 3D territory, I zeroed my trims & sub-trims. re-measured cg & repeated the flight test sequence to dial it in again and again. I wanted to start to feel & see the subtle setup differences. In my opinion Kody is one of the best in the Mob at the CG & trim setup art. I always quietly have my eye on him, watching & listening to learn something new.

Joe, nose heavy is not a bad thing! Tail heavy is much scarier for a maiden.

Andrew has a quote in the manual: "I prefer the forward rudder servo location with a DA-100 or DA-120 and in-cowl mufflers, this gives me the CG I want, which results in zero pitch coupling in knife-edge flight. I do not rear-mount the rudder servos unless I am running canister exhaust.”

I would move the rudder servos to the rear of the airplane like Andrew is suggests. That will give you the CG you are after. Then the rest of the gear can go in the normal locations and you should have a sweet flying airplane.

I have plenty more if you need to finish off your plane with it.

at the top of the RCG page above, click "MAPS"
type in Novato and you will see one club just north of Novato near Petaluma, and several just south of Novato

That's makes me feel better, that's why I had to mount everything rear of the carbon spar tube to get it to hang right. I'm going to relocate the tank in front of the tube so it's sure to favor nose heavy and give it a whirl

Thanks, Cry... I sent him the link. His father was an F-16 instructor in the AF and there also seems to be a club at Beale. Maybe that would be a good place to start -- even though the link is broken. He also writes the Rotorspeed heli section for MAN so I'm sure there will be some heli's involved eventually. Thanks, again.

Jim
