I just got done building this sweet little aircraft , I've been practicing flat spins on my G3 simulator , do you think this lazy tiger will do a flat spin ?

Un likely but you never will know for sure until you try it.

Enjoy,

Ok , maybe i'll give it a shot on my Funtana .40 tomorrow

OH another question ..

Anyone know why my .46 wants to stall when I try the hover mode in my funtana ? could it be to rich / lean ? I checked all the fuel lines and so on , they are perfect ...Running a PITTS muffler .. .46 FX

The .46 is probably too lean. On the ground hold the nose up at full throttle. If you hear a change in rpm richen it some. Keep doing that until there is no change in rpm.

Ummm, slight clarification, if the change is a reduction in RPM, it's too lean. I usually aim for a slight increase in RPMs when I point the nose up, because the engine will lean out a bit as the tank empties. If there is a significant increase in RPMs then the engine is too rich.

Citation, Your getting good advice but I have one more suggestion and that is to do your fine tuning with the tank a little less than half full/half empty. That has made a difference in tuning some of my planes.

as for the lazy Tiger... Great airplane...very fun... but no flat spins... I have tried and tried and tried.

How about adding a Saito FS 30 4 stroke to this plane !!! Just picked one up today,

What other plane would a .30 4 stroke be good in ??

I hope it will work ! Thanks for the input

You can flat spin it.

Any plane can be flat spun.

All you need to do is move the CG back, increase the elevator throw, and increase the rudder throw. The CG is the most critical. Move it back, back, WAAAAY back. And it WILL flat spin. Oh, adding a little ballast seems to help as well.

I have a trainer (Hobico Airvista) that will do wonderful flat spins. In fact, it spins better than my Funtana, which really doesn't want to flat spin due to the freakish airfoil it has. The trainer wouldn't spin until I added about 2oz of lead to the tail, moved the battery back, and increased the elevator throw.

Also, with trainers, the spin entry is a bit harder than most planes, since the light wingloading and airfoil design is such that the wing doesn't stall for long, if there is any apparently forward speed, the wing just won't stall. So, to spin the trainer, I'd pull in to a 45degree climb, pull the power back, and hold the nose up in the climb until the plane *STOPS*, then hold full up elevator, full left rudder and NO aileron. A quick blip of power will help the yaw on some planes, and enter the spin faster. Then I slowly feed in right aileron.

The exact technique varies with the plane a bit. On my trainer, the downthrust built in was such that too much power resulted in no spin, becaue the engine pulled the nose down and out of the stall. But it spun beter a couple of clicks above idle. So full-power flat spins were not possible. If I removed the downthrust, that would probably change.

Good info , I might try that !

What do you think about a .30 Siato on this aircraft ?

Got a Saito 30 in my Lazy Tiger. Nice flyer, loops from level flight, & resonable speed with 11x5 MAS prop, on 15% nitro. Beautiful sound!!!! Unfortunately, very limited verticle; a Saito 40 would probably be a better choice. Only about 1&1/2 oz more weight, & a load more power. ...... Bought a Combat Mustang to put another Saito .30 in, but looks like the rocker arm covers will be hanging out below the cowl. With no landing gear, I'm hessitant. ........ George K.
