Pizazz with a .61?
 
I've been wanting to try my hand with 3D and the Pizazz looks just right. THE engine of choice seems to be the Saito .72 four stroke. But before I spend $$, I have a couple of new .61 two strokes that I would like to try. Does anyone have any comments on how this would affect prop clearance and or CG. Thanks in advance. Warhwk

I'm not sure on the specs but you may want to check the weight of the 61's versus the Saito .72. I think you'll find that the .72 is considerably lighter than the 61. Example: I had a Webra .50 in my Top Cap. I changed it over to a Saito .72 and it didnt change the CG at all. I think a 60 two stroke would have made it nose heavy.
If you want to 3D the key is to be light. If you put a 61 in it and have to add tailweight to balance it you are just adding dead weight.
I know they are pretty expensive but my .72 is a GREAT running light engine. For plane like the Pizazz and Su-Do-Khois, Top Cap's Etc. you cant beat them.

Just my .02

You're right wgeffon!
 
Wow! I cant believe the Saito .72 is so light. Lighter than some .40 two strokes. But the price :confused: I already have a couple of two strokes. Now I'm wondering if the 5 extra ounces in the nose is going to affect my chances of learning to 3D. Does the Pizazz tend to come out tail heavy?

I dont know howlight the pizzaz is supposed to be but, I know my sudukhoi came out to 4.2 lbs and with a 46fx and 30% coolpower i hover at quarter throttle. It is light and powerful. you shouldnt need more than that and they are cheap. I have 2 and one starts easy and runs ok. the other is a little hard to start but turns rpm like i never saw on an os. Just hope you got a good one.

I think the Pizzaz is about a pound heavier that the SuDoKhoi..... Which would make the os 46 performance a little weak.... I've seen a few at our field with the Irvine 53. Great performance with that engine for around $100..... Hard to pass up that Saito though at only 16 oz.... wow... I be the torque rolls would be fanominal....

But the Irvine 53 is a definate option.

My first Pizazz (RIP) had a TT pro 46 with an APC 12.25X 3.75 prop, and it had plenty of power. I used two HiTec 81 MGs mounted to the bottom of the horizontal for the elevators because I didn't like that long forked push rod. I used a HiTec 425 on the rudder with Kevlor pull pull. A Hitec 81 MG on each airleron and A HS 80 on throttle. I used an 8oz Great planes fuel tank and a 700 mil 6V nicad that ended up in the fuel compartment with the tank. My all up weight was 4 lbs. 8 oz. This thing flew wonderful. I am going to my LHS on Satuday to get my second one. Fortunately I have all the raido gaer and engine ready for it:D

to say my point that the os would be enough, I had a TT46 on my sudukhoi and it hovered at 3/4 throttle. with no change in fuel or prop but i changed to the o.s. 46fx it hovers at 1/4 throttle. it has alot of power for it.

Ron,

Bummer about the crash, but you didn't tell us how it happened. Was it radio failure or what?

Thanks,

-Snaggs

DUMB THUMB, I had just completed a nice spin. I corrected for the spin and thought "that was too easy" so I corrected agiain. That second correction was one too many. I then ran out of airspeed, altitude and ideas all at the same time.
