Audacity Models Pantera 50 - Tiger 50 > Speeding up Tiger cyclic

I had the Tiger out last night to check some of the changes I have made. The latest changes include the hard dampers, Raptor green paddles on the Raptor 50 flybar instead of white and Pantera seesaw arms. The Pantera arms are a beefier part but without doing some grinding you can only use the outer most hole so it really didnt help. The orginal Tiger part it placed was warped a little so it was worth changing but from a speedup standpoint, it didnt do anything. John is sending me the 3 hole washout arms so I can move father in on those. There should be room for that. Headspeed is something over 1800 now. I dont know for sure 'cause I forgot to ask a clubmember to tach it for me. Anyway, it just keeps getting better. I havent ruined the Tiger's slow speed characteristics and it still hovers quite comfortably but it's getting tighter in loops and faster in flips and rolls.

It was interesting to note how the tail has become disproportionately faster as the headspeed has been increased. The perceived increase in headspeed from maybe 1650 to 1850 has been noticible and predictable but the piro rate seems almost twice as fast. I know, very unscientific but I've been hoping the tail would come alive and it has. Next time there's a club member around I'm going to increase headspeed to about 1900. I'll stop there until I get a governor installed to prevent unloading/overspeeding. The verticle was HUGE last night. The fact that the wind was HOWLING might have had something to do with it. It's been windy in these parts for days. Not great flying weather but at some point you just have to take what you get.

That polished off gallon #9, Wildcat 15% Helimix.

Marty,
Are you using the stock Tiger tail blades?
Remember that Tiger has a faster tail then most. The stock blades work great at higher head speeds.
I do have a pair Radix 92mm blades on my tiger and last week tossed the stock one's back on. I found that the stock blades piro rate was the same and I think my gyro was not working as hard.
I also noticed that moving the holes like you have done does speed things up. I went in another direction. Get wicked fast servos and poor the coals to them with six volts. A bit more spendy then your path but it works great. Your a flying fool my friend. Keep it up.

Yeah, I've been avoiding the faster servos. The Tiger was supposed to be a cheap fool around heli. I didnt want to drop $80 servos in it.I didnt think it would fly as well as it does. It deserves the better servos. I'm running 76in/oz at .17. After the washout arm change and confirming I have the headspeed at 1900 or a little above, if it continues to improve I'll probably pull some 9402's out of something to get the servo speed to .11. My Raptor 60 is getting the first 9452's I've ever tried. They're .11 as well.

Oh, yes I am running the stock tail blades. I like them.

good news flying the stock tail blades. JB did his homework on this one.
My servos are .06 @ 6v Granted the price per servo is a bill a pop.
Yup your right that the Tiger is a fool around ship. Then again when your done messing with basics it's time to go from mild from wild!
My Tiger night ship is flying in the stock mode. I'm a weenie when you can not see the ground untill the neon lights up the landing area.

Do you know HOW to measure CYCLIC pitch?

This make a world of difference too. You say you did not check it in your last thread. It will make the heli roll, and flip MUCH faster if set higher. But you have to be good with collective so you dont bog motor. Even with the servos you have. Once fully deflected, the servo holds in place, pitch makes it roll-flip faster. 7-9 degrees is good.

I said I didnt know what the cyclic was set at because I had torn it all apart when you asked the question. I'm usually in that 9 degree range and I do bog some. It's a balancing act. On this ship I have slow servos and crap blades and am simply trying to make the most of what I am working with. Given what THAT is, I'm pretty happy.

Oh, I forgot to mention, I popped a hyper carb and head on the existing engine and woke it up. I have flown both engines before and never considered the hyper that much more engine than the non-hyper but I couldn't have been more wrong about that. The difference is siginificant. It'll definiately be hyper as a minimum from here forward.

Hyper all the way bud.
Put one in your Pantera and enjoy the fun.
All my ships get a Hyper and a Pro or CY pipe.

I hope everyone found time and weather to get out and fly some this weekend. I managed 7 or 8 flights (3/4 of a gallon of fuel) and had a ball. The Tiger, or Tigre as the decals say continues to fly beyond my expectations.

Blades for 50 heli

I switched from the "sport" version of the Mavrikk G4 blades to the Radix wide cord blades on the Tiger this evening and all I can say is WOW! I won't be going back. I have reached the type of flying where I can see, hear and feel the difference. I wouldn't hesitate to fly the G4's but I definately won't be buying more.
