pizazz modifications
 

I have decided on a Pizazz for my first 3d plane as they are easily available here in Australia, however they are know as a whizz here. Anyway, just wondering about any mods for this plane, such as elevator servo's in the tail and a rudder pull-pull set up. As well as the does and don'ts of the kit. Has anyone done these mods? If so could you tell me how you did them or post some photo's. I plan to run a os46fx with APC 12x4 prop to start with to see how it goes, then I may step it up to a 60 or a 70 4stroke. Do you think it will hover on the 46 if I keep the weight down?

Thanks [:-]

RE: pizazz modifications
 

i bought a pizazz to replace my ultra stick 40. a thunder tiger pro 46 with a macs pipe would pull the us 40 out of sight. the pizazz is a little lighter. the tt pro 46 w/ pipe and a 11-7 prop on the pizazz would hardly pull any vertical. i guess because of the thicker wing. i tried a 12.25 - 3.75 prop and got better vertical but still not enough. i put a mds 58 in the pizazz and it hovers at 5/8 throttle. i would like to try a saito 72 in it. i would definately use more than a 46, perferably a 60 . i had to add alot of down thrust to the engine. it would climb like crazy at full throttle, 2 washers under the rear mounting holes on the engine cured that problem. that was after i almost crashed it on the first flight when i couldn`t keep the nose down, i don`t know how i got it back down safely? added 1 washer & tried it again & got almost the same effect. now it flys good. even with the 58 in it, it needed nose weight, so rear mounted servos might be a good idea. its a real fun plane to fly, it takes off fast with the 58 in it & it really slows down to land. i put as much throw on the control surfaces as i could get on them , cut them down with dual rates and used the expo. suggested in the manual. the expo. really helps me fly it. i hope this helps you . have fun

I'm using an OS 61FS 2 stroke on mine with a 14x4W APC. Barely hovered with a 12x6 but it's a rocket with the 14x4.

Needs counterbalances...

RE: pizazz modifications
 

There has been a hugh amount of info posted here on the Pizazz and what numerous people have done with them. Do a search on Pizazz and you should be overwelmed with more than you ever wanted to know.

I've powered mine with a TT54FS, Saito 72 and YS 63. The plane comes in at about 5.5 lbs. Unless you take extraordinary measures to take a lot of weight out I don't think a OS46FX will handle it. Maybe with a mousse can. The TT54 sure wasn't enough but both the Saito and YS were

RE: pizazz modifications
 

Mine bit the dust after 500 or so flights when the elevator servo quit. An Irvine 46 would not hover the plane however the 53 did with no effort. Nice since the 53 is the same case as the 46. Most 60's are quite a bit heavier. Change ALL the hardware to ball links and fiber rods. Extra weight will be no problem in the tail as mine needed tail weight to hover well (even with a lighter engine). I would like to see this plane with 3" more fuselage length.

EXCAP232

RE: pizazz modifications
 

no wood dowel pushrods, higher torque servos, I had a TT 61 mounted as close to the firewall as possible and it balanced in the middle of the recommended range with the battery behind the tank, I was moving the cg back and had the pack as far back as the rear of the wing when I lost it on a deadstick. Too low, Too far away. I replaced it with a funtana and the jury is still out on whether that was a good idea, the snow has come after only a handfull of flights :(

Here is what I have done
 

Servos
Throttle - Hitec HS 5475HB Standard Digital
Rudder - HS5975HB Digital
Elevator - HS5245MG X 2 mounted staggered in the fuselage back by the tail
Aileron - Futaba S9001 x 2

Really like the digitals. Fast and accurate.

Engine Saito 72. Would go with YS 63 or Saito 91 if I were you. Definitely go four stroke for swinging a larger prop. Started with 13x6 then 14x6. Too much pitch and too fast - not for me just for the plane. Have someone at the field that has a profile and can't fly very well. All he does is fly full throttle and around in circles. Currently have a 15x5 on it. Great prop slows down wonderfully and really torques for tumbles and flips.

Put TALL aftermarket Ultra Stick gear with H9 3.5 inch lightweight wheels. This is necessary with a 15" prop.

I used ball link ends and a pull pull on the rudder.

My CG is 1/2" back from recomended setting.

Here are tail mounted servos
 

They are staggered so only the top sticks out of the fuselage. I just CA'd a small piece of ply on the inside to screw into.

RE: Here are tail mounted servos
 

Do you have some video of your Pizzaz flying??

Thanks!!

RE: Here are tail mounted servos
 

This really isnt the best airplane for 3D.

RE: Here are tail mounted servos
 

you're right, this is a fun fly airplane!!

RE: Here are tail mounted servos
 

Don't have any video, sorry. I get to the field with my 2 and 5 yr old boys and it's all I can do to concentrate on flying. Got in an hour straight this afternoon. Hi 60's and no one at the field. Landed just enough to fuel up and go (4Xs). 12 oz on Siato 72 just enough to squeeze 15 minutes. Need some more right and down thrust - even more so with 15x5. Goes left and just a bit up on vertical.

If I can master knife edge on this I will be set. Short coupling makes the slightest movement a bit of a scare.

It will slow down to a crawl. With 15x5 it will literally stop and not stall.

Full travel on elevator makes it want to snap at anything above say 5 mph. Gentle but not comfortable.

Really don't know what full throws gain in this bird. At the slightest speed it moves way too fast to manipulate a tumble, lomcevak, etc. About half ailerons and elevator with full rudder throw seem about right. Beyond that it is just a blur, even post stall.

It's a reall catch 22. Have to keep it in close to keep visibility up. But in close only gives one less than a second to recover from a tumble, flip, etc when the exit is unexpected. Came close a few times today.

Have a SPAD that hovers like a baby. It has two stroke on it. If it falls to the gound it gets picked up and flown again. I know this wouldn't happen with Pizzaz.

Reinforce the landing gear area with some coarse fiberglass. It comes apart easily. I had a dead stick and came down in a stall from about 4 inches and off came the gear and the lower hatch. Easy repair but nonethe less PITA.

If anyone has come up with some good spins or tumbles with this plane please let me know. It will take all the full throttle ups and downs I can give it. I do not have any stock control linkages though. I will say full throttle and some guts gets it to some interesting things. The more repetitive you can do rolls or snaps or tumbles the more violent and faster they become.

I think a 4 Stroke and a 15" prop (1/3 wingspan) is coming close to what a real Sukhoi can do in repetitive rolls, spins etc. I like the idea of the 1/3 Sukhoi but without a huge pro being gear driven I think the whole perspective is lost. That is the only claim to fame the Sukhoi has is the huge lower pitch prop the gear driven drive train the plane can handle. But no one yet even begins to understand the advantage of the big prop and the torque it can throw around.

I have heard that mixed arguments about RC vs Real. RC - engines can't swing a big enough prop to get enought torque to: Lomcevak and get real torque rolls (BS). RC can outperform real in a weight to power (true).

What real plane does anyone know that could swing a prop 1/3 of the wingspan. Not even the Sukhoi which is easily twice the weight of an Extra, Pitts or anything else I can think of. So we can throw a prop larger than a real plane at much less weight than a real plan.

Now everyone lok at Sean Tucker, The Bulldog Pitts. Goiulian, Chambliss (you can drink and fly) etc. We should be able to flip and get some climbing tumbles etc that really kick but.
Any ideas?

RE: pizazz modifications
 

have pizazz with os 46fx piped....will hover but no 3d [:o]


I also changed the stock hardware out, went with 4-40 stuff but still used the dowels......what a b**ch


I can sometimes get it to harrier with wind and by not trying to use all the elev throw.


will do walls, and I can get it into a powered flat spin, but it looks really stupid if you ask me.


Running a 11x4 prop, I use mine to hover with, this plane is even hard to hover, but it is good practice for my 33 and 35 %

Want a true 3D .40 size plane? Get a funtana


just got mine.......recovering right now, very ugly stock

RE: pizazz modifications
 

oh


BTW, the funtana is getting a satio 100, not sure if a .40 would do this one

RE: Here is what I have done
 

MAN!! You do not mess around, .......the $1000 fun fly LOL!

RE: Here is what I have done
 

Thanks guys, I think I will still use the 46 to start with, and see how it goes. Then if needed I'll step it up. Have heared a lot of people say a good 46 matched with the right prop is enough power. But we'll see in time. :D I can't really afford all digital servo's! Will the hitec HS425bb be good enough for moderate 3d? (i.e. Hover, torque roll, waterfalls, harriers, elevators) Also is a 5 cell Rx batt pack a good idea?

RE: Here is what I have done
 

I am running 4 cell 1100 mah. Get 4 15 minute flights off full charge. 5 cell would add even more weight - I wouldn't do it.

RE: Here is what I have done
 

I doesn't matter if you have jumbo servos in this plane, it will NOT 3D. standards are ok, I have a hitorq on my rudder.


Hover - yes but difficult due to short tail
Torque roll - a little with a 46. hard to keep rolling
Waterfalls - absolutely out of the question, will not stall, just chases tail in a fast circle
Harriers- way too much wing rock, may get a partial harrier in wind, plane does not like high alpha
Elevators - again, out of the question, the wing rock is terrible

I have tried spoilerons, and flaperons to resolve, still no 3d


this is not a 3D plane, just a cool looking fun fly, H9 3D .40 size plane is the Funtanta.


You might want to also look into the Morris hobbies profile 3D planes, or the GP ucand3d .46


I bought my Pizazzz with the hopes of 3d, but it is not in the cards, it is not a lot of money, but there are other planes out there that perform better......much better

RE: Here is what I have done
 

Agree 100%!!!
:D

RE: Here is what I have done
 

I would have to disagree.

If you keep it very light and the CD way back, it will do anything you want, and much slower.

Use a small AAA NiMh pack, not nicds.
Drill the gear or use something lighter.
Use Ultra light tires.
Use a mini or micro on throttle.
Use HT mini's on the ails.
Use P/P on rud and a carbon or glass rod on ele.
Use a wood prop, not a heavy APC.
No spinner, pilot, canopy or anything not necessary.
With a .46 on a light pipe (Macs) it will come out just over 4 lbs. and easily pull from a hover with an 11x6, so it'll be fast enough to do something other than hover.

Now, move the CG (batt pack) back until the tail starts to sag at low speed when the tank is low.
This plane is very forgiving tail heavy, most aren't.

A 4 lb. Pizzaz is night and day from a 5.5 lb. one.

RE: Here is what I have done
 

I have heard that micro or mini servos burn out or srtip gears on 3d and funfly aircraft very quickly due to the amount of work they have to do. Is that true? If the pizazz doesn't 3d what can it do? Also I thought a wood prop would be heavier than a glass/nylon prop.

Servos and weight
 

Digitals - had the rudder laying around from a burnt up Sig - smooth and fast for rudder. The tail servos just seemed to fit. Wanted to try a digital on throttle to see about a real accurate idle - definitely worked.

Minis anywhere would be way slow but light. Used to always use mini on throttle but an ultra low idle with the accuracy of a digital makes it slow on a dime. Won't use any more slow servos.

Lighter battery pack would be awesome.

Keep it light yes.

Lightest wheels Kavan. I have H9 light wheels but Kavan at least an ounce lighter.

Still push for 4 stroke. A world of difference between a 14x6 to a 15x5. Started with a 13x6. Too much pitch and your back in the 80's with an Ugly Stick on a 60 with a pipe.

Bigger the prop more right thrust and you will need some down.

This plane gains nothing with speed.

I am 1/2" back from recommended rear and it could go much further back. I can literally stop in the air nose up with no stall.

I was hoping for more out of this plane. But it does keep you focused when you ring it out.

RE: Here is what I have done
 

Kirk


that is great that you have this plane at 4 lbs, and I am sure it flies nice...........but will it 3D ????



This also seems like a lot of work as compared to to a UCD3D .46, funtana .46 or profile that will fly 3D stock out of the box.


The days of the pizazz are over, look on horizons web stite.......it is gone.


Not saying that it is a bad plane, it is a cool plane that looks cool in the air and out of a hover.......but for 3D there are MUCH better solutions out there.


IN MY OPINION




To answer the question "if not 3D what will it do?"


Rolls fast or as fast as any plane I have ever flown

lands at walking speed or less

Cool snap roll to hover, snap roll to hover, snap roll to hover........

Very fast plane for such a thick wing, even with a 4 pitch prop

Chase the tail loops


basically 2 year old fun fly stuff, not up to the new age of fun fly 3D

RE: Here is what I have done
 

Still sounds like an mad plane to own!!! I will still get one.... Will it do knife edge loops? Has anyone made it fly backwards? Always thought that is one of the coolest tricks a plane can do!! I'm not after an all out 3d machine as I am new to 3d flying. Spent most of my time doing sport aerobatics. Is a pull-pull setup on the rudder a good idea or should I run the standard setup? Never used a pull-pull setup before! Is it hard to do? :D:D:D
