RE: Richmodel "Quickie-40" from AK-models.com
 

Hi There,:D
Your experience was very similar to mine. After moving the CG back (it could be even more then what Rube G. suggests) and using the entire runway I got it flying. I made my first turn and came back just in those few moments I must admit it looked cool. Then I made another turn to bring it back again and that’s when I lost the elevator, and that was it.
Rube G. had a very good idea…use standard landing gear. There is actual a full size plane similar to the Quickie with standard gear I think it’s called the Dragonfly. See RG’s last post.
I really don’t think it’s an engine problem I used an OS 46 and it moved like a bandit...it could fly with 40. My opinion, for what it’s worth, is it’s in the CG and in the elevator. If I was going to build another, which I am not I have other fish to fly :D I would rework the wing and enlarge the elevator (at least a 1/4 inch, either ad to it or make a new one) to give it more surface area and try to get the maximum throw.
There is one other thing to consider which I don't have much experience with and that’s the incidence of the wings. The reason I say that is I met a guy at the Jan. 07 AMA show who has built several Quickies and won second place in the building completion. From what he said he had changed the incidence. Sorry I don’t remember exactly what he said. I just spoke with him a few moments and got a couple of pictures of his ¼ scale Quickie.
I know reworking the elevator is a lot of work but as I said my opinion is that the elevator lacks adequate surface area and throw. Also make sure all the gaps in the ailerons, elevator and rudder are either filled or as close a possible to avoid control issues. Soldering the control connection to the elevator is a very good idea too.
Good Luck and Happy Flying!

PS...Rube G. not "Ruby" [sm=spinnyeyes.gif] has some very good suggestions in his posts. He seems to have the most experience with this model that I could find.

"So I am going to order another, because the brief moments it was in the air, were great."

Hey now! That's the spirit!

Still flying mine and everything is fine. I've been tempted to pick up one of the little electric versions of the Quickie, but for the same money I wound up purchasing one of the Herr Engineering/Sig "Little Extra"s and converted it to electric with an E-Flite Power 10 motor. Unlimited vertical and just a blast to fly. The downside is I've modified the firewall with a large hole and added a rear facing scoop on the bottom of the fuselage below the battery to cool things down, and it's still not cooling very well.

Since it will probably be about 102F AGAIN today here in Mississippi[:@], I might just leave that one at home and go fly the Quickie today.[&:]

RE: Richmodel "Quickie-40" from AK-models.com
 

I've got a Quickie that I've had in my stash for about 18 months. I figure I should let them breathe before they cra....er FLY! After reading this thread my thoughts go to stripping the covering off the bottom of the wing (not too crazy about the scheme anyway) and perhaps glassing some carbon fiber across the bottom for reinforcement. Does anyone see any problem that this may cause possibly to the an-hedral? Also, one trick I've been using on a lot of kits I've had is to glue triangle stock to the leading edge of the surface, sand flush to fit and recover. This gives me a deflection of 45 degrees in either direction with no flutter when the surfaces are tight. Anyone?

Thanks!

talk to rube, he is the man with this plane

RE: Richmodel "Quickie-40" from AK-models.com
 

I think you are going to be really frustrated when trying to remove the covering. The stuff will seperate with a clear layer on the outside, leaving you with the colored layer still stuck to the wood and getting that stuff off is kind of like dealing with old fabric and Balsarite. Scrape and sand!
I'd give the canard the "rebound test" before trying to improve on the structure. When it is installed on the plane, if you can push down on the top of the fuselage over the canard (somwhat lightly!) and then let go and the canard has a nice "rebound" effect then it's probably alright. Seems the "weak spot" where the canard will fail is the joint just outboard of the edges of the fuselage. So if you were going to install some carbon fiber, I'd center it on the canard with a length of about 3 inches past that joint, i.e. the length of the carbon fiber would be the width of the fuselage at the canard + 6".
Of course you could modify the landing gear to that like the Dragonfly and then the initial landings wouldn't be so critical.
I've flown mine several times since the initial problems with the canard, and it hasn't had any issues since. Good luck and have fun with it!:D

RE: Richmodel "Quickie-40" from AK-models.com
 

Covering is not a big issue. The next time you come across that type of covering try dipping a small section of scotchbrite pad into alcohol or acetone and rubbing the left over film off. The acetone might be a little harsh but if the alcohol fails then there's always something a little stronger.
On the carbon fiber, I'm not talking about the rod stock. What I'm looking at is Carbon fiber matting. You can get it in various sizes and thicknesses. Lone Star Balsa carries it in stock. I usually take a trip down there every couple of months to stock up on more wood. I've been doing a little scratch building here and there.
Back to the question though, which is if I apply the matt to the bottom across the points of the an-hedral(s) and like you said probably around 3 inches beyond, do you think that the force of a hard landing might cause the two spars to crush into each other given the shear web is grained in the wrong direction? Just trying to figure out if I could go in and operate before flight. I'm not too crazy about discovering the problem in mid-flight. I like the Dragonfly concept but I was thinking about looking at the amount of work I would have to do to keep the original design before I went on to that modification.

Thanks!
John

RE: Richmodel "Quickie-40" from AK-models.com
 

My thoughts were that IF the canard passes the "rebound test" outlined above, then I'd fly it as is. Then if you had a not so smooth landing and did damage to the canard, that would be the time to go in and fix things.
I think the carbon fiber matte on the bottom of wing would hold fine....to the sheeting.....as it would be in tension. You could even put the matte on the top of the canard in hopes of reinforcing the sheeting which would be in compression. That might require work to the canard saddle of the fuselage, depending on how thick the mod is. In the end, I think you would only be reinforcing the sheeting of the wing, and not the internal structure. A rough landing might still cause damage like you say to the spars getting compressed together at the joint where the center part of spars meet the swept back spars.

It'd be kind of like dropping a turtle off a second story building.[:'(]

Lesson #1 I learned from Rube Sr. Structural PE was that "if it doesn't bend, it WILL break!"

I got my Quickie last week I plan to start tonight I'm putting an O.S sx 50 in it with futaba 3010 servos. If the wether is good I hope to fly it at our new years fly in.

RE: Richmodel "Quickie-40" from AK-models.com
 

Hey all, I ordered one of these quickies last week because I just love the design. It looks like there is a lot of issue with the CG of this plane. So I went online looking for the formula to calculate the CG of the plane. I found this listed by a gentleman named DanSavage on RC groups. Since I don't have my plane yet, I can't do the calculations but if anyone else is interested here is the information.

Hi,
Does anyone know who is selling the Quickie-40now?

try ebay or ak models

RE: Richmodel "Quickie-40" from AK-models.com
 

Shubbova I sent you a PM, if anyone else is interested I have one NIB I'll sell for $150 shipped to lower 48 states. Let me know. I ordered it, put it in the closet and never got around to it, I never even opened the package.

RE: Richmodel "Quickie-40" from AK-models.com
 

I just picked up one of these at a swap meet. I've been reading the posts, and was wondering if any of you guys had tried adding another servo to the ailerons, and using flaperons or spoilerons? Seems that using spoilerons might help the flairing and the nose-over problems. Wouldn't spoilerons (both ailerons up) bring the tail down?

RE: Richmodel "Quickie-40" from AK-models.com
 

....or maybe program an elevator/flap mix, so that the ailerons go up as up elevator is applied?? I've installed another servo, and have programmed the mix. All that's left is to get up high and see what happens....[X(]

RE: Richmodel "Quickie-40" from AK-models.com
 

As far as the mixing the elevator/flap I don’t really know. It seems to be a risky thing to do.
If I were you I would check the elevator movement first and then the CG. I believe on a canard the elevator moves in the opposite direction. As we all know in a conventional plane when the elevator moves up the plane goes up and down for down but in a canard when the elevator moves down the plane goes up, it’s reverse. When I first tried to fly the Quickie I couldn’t get the thing off the ground, it would nose down even when I moved the CG back. Someone mentioned to me that the elevator is reversed in a canard. After I reversed the movement of the elevator it took off using a lot of runway. I think the only reason it crashed it is the CG was to still too much forward to maintain flight. You could contact someone at the websites that have shown below. I never fixed it or bought another one so I’m not sure were the CG actually is. That is one of the problems with this plane; the location of the CG is farther back that they recommend.

You should consider using standard landing gear; it seems that the wing is not strong enough to take the shock of a hard landing.
Rube G. seems to have the best to offer on tips for this plane, but read all the posts carefully and make your own decision.

The reasons I bought the Quickie was I thought it looked cool and it did for the 1/2 minute it flew. I also like unusual things and it did have my curiously, I’m still trying to understand how different planes fly. So far I’ve owned trainers, intermediates mid and low wing, aerobatic, military and biplanes. And the Quickie by for was the most unusual. Every time someone writes in on this thread I kind of light up and want to buy another one, maybe one day. What did you pay for yours?

In one of my previous post I mentioned this as a bit of trivia. I saw a scratch built Quickie at the AMA show in Ontario, Ca a couple of years ago. It was ¼ scale and it was realistic down to the nuts and bolts. He only flew in the desert were he had a lot of area. He said it was build it using modified full scale drawings. I will include pictures in this post. They are kind of fussy, I used my cell phone.

There is another version of the Quickie called the Dragonfly it has standard landing gear. Here are a couple of interesting websites. You may want to check with these guys about the direction of the elevator movement.

RE: Richmodel "Quickie-40" from AK-models.com
 

I've been reading the posts, and am aware of the CG issue, and that the elevator should move opposite from a normal plane. I have the cg at 3 1/2" behind the trailing edge. I have my elevator throws set as far as possible, and I have re-inforced under the canopy, in case it does nose over. I have the elevator/flap mix on a switch, so that I can disable it if I need to. I paid $150 for the Quickie, with servos and an OS .40 with a pitts muffler. Seller said it had never been flown, and it looks like it.

RE: Richmodel "Quickie-40" from AK-models.com
 

Well Scott,
Looks like you have it all covered. $150 with engine and servos is a good deal! Let us know how she flies.
I just might start looking for another one myself.
Something else I just thought about. I don't remember how hard the tires are but you may want to consider a softer tire for softer landings.
Good Luck,
Shubova

RE: Richmodel "Quickie-40" from AK-models.com
 

Thanks for your help. I'll let you know how it goes. I hope to fly it tomorrow, weather permitting....should be interesting, to say the least:D

RE: Richmodel "Quickie-40" from AK-models.com
 

Well, I flew the Quickie today. Didn't get 3 feet away before it nosed over. Needless to say, up elevator (or down, in this case) does nothing to help. Finally got it in the air, and it flew great. I've got my cg at 3.5" behind the trailing edge of the canard. Brought it in for a nice soft landing. I've got an elevator/flap (actually spoiler) mix, so that both ailerons go up as up elevator is applied. It flairs nicely with this setup.....anyway, it rolled out about 4 or 5 feet, and nosed over hard, cracking both wheel pants. I took it home to lick my wounds, and to wonder why I bought this thing, and I came up with a simple solution. I found the front gear from an old trainer, and mounted it to the firewall, making sure to secure it so that it wouldn't turn. Took it back to the field to try again, and it worked great! I could't make it noseover, no matter what i did....NOW I'M HAPPY :D:D Brought it in for a landing...nice flair...nice, smooth touchdown.....perfect!!! The Quickie has gone from being a pain, to being a joy to fly. I thought some you Quickie owners might find this info usefull......

RE: Richmodel "Quickie-40" from AK-models.com
 

Question for you Quickie owners...do the instructions call for up-thrust? Since I bought mine used, I don't have any instructions, and mine looks to have some up-thrust.

RE: Richmodel "Quickie-40" from AK-models.com
 

Scott,
I didn't find any information on up thrust. The manual is very poorly written...just basic assembly.
If you want a copy of the manual, I send you a private e-mail through RCU. I don't how to post is via this format.
One more thing as I remember when I spoke to the guy who built the one I saw at the AMA show. He said don't try to do any fancy aerobatics with this plane. It was built as an experiment by Burt Ratan and it only will do basic flight. You will be lucky to get a loop out of it. It's an interesting plane isn't it? I wish I knew more about aerodynamics, them maybe I could understand the concept better.
Good Luck,
Shubova

RE: Richmodel "Quickie-40" from AK-models.com
 

I'm having a ball with mine, now that I've conquered the noseovers. I wonder how well it will loop with the elevator/spoileron mix? I might have to give it a try:) I sent you an e-mail before I read your post. If there isn't any info on up-thrust, there's not much need for the manual. I appreciate your help, though.

RE: Richmodel "Quickie-40" from AK-models.com
 

Well I if you ever want the manual let me know?
Have Fun...that's what it's all about!

RE: Richmodel "Quickie-40" from AK-models.com
 

I had the RichModels Quickie. 3 flights and into the trash....

CG in maual was very wrong! climb out very sluggish & would not flare to land...wreck #1
Move GC back 10 mm would not flare to land...wreck #2
Move GC back 5 mm more MAX elevator throw... would not flare to land...wreck 3 canards split.

I have the Keith Sterner RCM Plans should have checked his CG first.
He also put and aluminum brace in the canard which was a 3 piece foam cored wing.
Some where I have a box with foam cores, balsa wood sheeting, machined wood formers, cowl and canopy.
All of these parts came from Cressline models. One day I will build it from the plans.

The rights to make a kit were sold to St. Croix models. Who then sold them to Cressline.
Cressline produced the Quickie, Long EZ, and two versions of a "CanardStik".
Cressline later became Flighteck.
Flighteck focused on building ducted fan kits. And then closed their doors.
