Eric,

Any updates on how the new Quest came out???
I've been thinking about putting together another one so I'd hava a spare.

No updates, I'm just waiting for the snow to go!

I apologize for not posting the weights again. I can't find the scrap of paper that I used as a notepad. To weigh them again requires a bunch of bench clearing etc. I'll do it as soon as I get a another spare moment. The Mk-2 was ligfhter than the Mk-1

Eric.

My Quest -2 flew today. It is powered by an old YS 91 so I had worked on keeping it light. It all paid off. The 91 using a 13 x 10 APC pulled the new Quest-2 with total authority.

The plane performs much like its precessor. The snaps are much better and the spins work well with rudder and elevator only.

On my first Knife-edge test I was on low rudder rate and when I 1/4 rolled and applied the rudder it performed a 1/2 loop in the KE attitude. The low rate rudder is now my high rate and I am only using about 1" each way on the pattern setting.

It was a bit breezy, (it's March!), cross-runway and bumpy, but so far the KE looks like it needs no rudder mixing with aileron or elevator. High-Alpha KE's were easy at not much above high idle. Slow rolls were very easy to do and the loops were right on all the way round. The strong rudder allowed for very good wind correction.

Landings could be slowed down to a walk and very gentle.

What else can I say, "It's a Quest that is better than before".

Regards,

Eric.

Some in flight pics. Thank to Gerry Geyster for the camera work.

That's a very slow KE in th first picture. You can see that very little rudder is required. In fact I used more rudder for the last picture to do a very slow side slip for the camera.

Although I write this up as a pattern choice for a practice/competition/entry pattern plane, it also has major 3-D capabilities. I just let the young bucks do all of that stuff as my reflexes slow down (BG)


It will do some very good High-Alpha on high pattern high rates. I think that they took some "boring" video while I was in the air. You might keep an eye out for that on the ultra-RC site when they get it loaded.

Regards,

Eric.

YS 91 needs some cool air. New muffler with steel retainer rring from Dave Schadel.

Four more flights today once I fixed a completely stuck closed check valve. (Had a few do this and and I can't see why yet)

Still no KE mixes needed yet. The rolls can be as slow and as long as you like with this plane.

Regards,

Eric.

Yes, that is Temptation landing gear! It was already made up and a couple of oz's lighter. Probably should have gone with the kit supplied gear to keep the weight better distributed.

The CG in the "manual" is right on for pattern, rolls, snaps, spins and the like.

I now carry a tad of up trim but it doesn't seem to affect the up amnd down lines etc.

Eric.

Thanks to a rainy-day(3/20/2005) I was able to shuffle the planes around the garage and do the weighing again.

Quest-1
Fuselage 7lb 3.5 oz
Wing and belly pan 2 lb 3.5 ox
Total. 9 lb 7 oz. This is with a YS 14.0L, CD header, Hatori pipe and 9411 SA's in the wings. Bolly gear. Hyde 1.40 "A" mount.

Quest-2
Fuselage 6 lb 7.0 oz
Wing and pan 2lb 7.9 0z
Total 8 lb 14.9 oz. This is with YS 91, Perf Prod bend and muffler, 8321's in wings, Temptation gear, Hyde 1.10 "A" mount.

Both planes will go "vertical!" at these weights with these engines.

I think that a 1.20 FZ would give great perfromance and a perfect CG with QUEST-2.

Regards,

Eric.

P.S. A tip for you YS 110 users is to screw the transition screw in all of the way and set the idle with the regulator, just like to old FS's etc. This really helps the lean condidtion that some 1.10's experience. Good luck.

So, do you think a Saito 100 would be ok for this. I am looking for a home for my saito 100 and love the way this plane looks. I am concerned about the weight of the saito. I am not sure that it's heavy enough and I don't want to have to add weight just to get it to bal. Any suggestions would be appreciated.

I am not a pattern flyer, just typ. sport flyer. However, I do want to have a very nice flying airplane that could also do a few tricks (I also fly a funtana 90). I am wondering if It would bal. if I put the servos up front more.

What is the weight of a Saito 100?

Regards,

Eric.

Saito 100: 19.2 oz less muffler, 20.9 total.

The YS 110 is 27.4 oz without muffler.

If you used a big old Dubro iso-mount, which weigh in at around 8 oz, and be sure to mount the engine as far forward as the cowl is supposed to go, you should be in good shape.

Regards,

Eric.

So if just using the satio and reg. mount, could I mount battery pack up front in the firewall area and have it still bal. out. What about placing servos up as far foward as possible?

CG's are usually about a 2.5 : 1 ratio between the tail moment and the nose.

So if you move a 2 oz servo from the tail you roughly gain 5 oz in the nose. Or said another way it's like adding 5 oz to the nose.

Of course you have to add a pushrod to the back so you would get about 4 oz in tail weight relief. With all of the stuff (battery etc) forward you would probably balance. I can't promise you that because each plane is different.

I have seen many Quests running with lighter 2-c 91's and tuned pipes, or not. They all balanced. I can't guess much more than this.

Regards,

Eric.

Thanks Eric. I know you state how well this plane flys. However, how do you think it will also fly minor 3d stuff descent? Will it do flat spins? I had a Sensation one time and I could only get it to do inverted flat spins. Upright had to be done under power and where marginal at best. I appreciate your help on this.

The full name of ths plane is a 3-D Quest. I use pretty conservative throws for pattern flying. Other pilots jack up the elevator throws and do a bunch of full 3-D flying. There will be a video coming out of how it does both. I have seen it do all of the 3-D stuff, hovering, blenders etc. Not quite my cup-of-tea, but pretty impressive. I believe that they move the CG back a bit for the really wild stuff.

Regards,

Eric.

does the engine have to, be mountied inverted

You can mount the engine sideways if you want to.

Regards,

Eric.

What pipe and header set up is being used with the ST90 on this plane? Thinking of buying this thing but, want to use what motor and radio gear I have.

I think there was one of the older Quest flying at our field with a OS120 and it had tremendous power. Just had all that pink on it. Could have been a different plane though.

The mark-2 is red, thankfully....

So Eric, you still enjoying this airplane? Anything new to report? Thanks

I flew them both on Sunday. The older MK-1 with the YS 1.40 and the new MK-2 with the YS 91.

I like the lighter new one with the 91. It is a blast to fly a bit wild and then very satisfying to fly as a pattern plane. The shorter wing makes it snap better. I have to change rates on the old one to do a snap. The new one feels like it is tightly connected to the sticks in my radio.

Hard to beat this much fun from a $250 ARF.

I did complain about the pipe-tunnel/pan being pre-cut for ventillation. If you use a YS perf muffler then you don't need the cut-outs. I covered the center join with white Ultracote so that you don't see glass-cloth and wing-wood through the slots..

Also I have been using upgraded YS muffler that has a steel ring around the neck near the elbo. It is solid and shows no signs of leaking or comming loose.

Eric.

Thanks for the update. What size prop are you running on the ys91? Does the 91 provide unlimited verticle? I am just trying to make a decision if I want to use my saito 100 or purchase a YS 1.10.

Thanks

Yes to the vertical.

APC 13 x 10.

The 1.10 version I had would turn a 14 x 12 or 11 or 10 etc.

I would run the YS 110 period. Just screw the YS 1.10 transition screw in all the way and it should run great after that. (Stops prop-kicking)

Eric.
