Im running a Hyper on youngblood 30%. Doing sport flying Im getting about 6.5-7 mins. I was running 1750/1850/2000 HS in all three of my modes.

I have made some changes to my HS and pipe. Now running 1800/1900/2100 and changed to a MP5 pipe. Also -11 +11 pitch. I dont know what rich or lean looks like this is my first nitro heli, been flying 600CF lipo / 450's.

The power is good with the previous HS on -10 +10 pitch. I guess I need to find where the sweet spot is as far a power band on this hyper and also find a tuning video online.

When I land the heli I have alot of nitro oil on the landing gear, etc. I can also hold my finger on the bottom of the plate almost forever. I can keep my head below 200 degrees but I expected less oil caked everywhere.

8:30 the timer goes off then a couple minutes of auto's. During the first 8:30 I think I fly it pretty hard. 1950 headspeed, 3000 foot elevation, temps high 90 to low 100's, 30% fuel.

There is a very fine line between "hobby" and "mental illness."

9:00 and I start auto practice. At this point I usually have the header tank full and a few drops in the main tank.

20% nitro, 100ft elevation, 90F here, 2000 rpm headspeed, 12.5 deg pitch and I'm practicing tic tocs (both upright and sideways) so guess what I'm doing all the time?

Main Needle is at 1.25 right now and the idle needle is at 1 o'clock

I started all over again with the needles rather than fight a bad tune.

I changed it back to 1.5 out on the HSN and 12:00 position on the screw. When I start to spool up to hover the engine almost dies. So I then leaned out the screw a couple of degrees. Now it will spool up smooth but not too fast. I flew it like this got about 4.5-5 mins but power was good. (as far as I know). Then I leaned the HSN about 2 clicks at a time for a total of 4 clicks. I can place my finger on the backplate with put having to remove it for about 15-20 seconds. Power os about the same as my 600CF with stock gear and a TP5000 lipo. Maybe a little more.

I guess in order to do a climb out to see if the motor goes lean I would have to INH my ATG from holding the HS at 2100.

What would be a good power band to be in as far as HS with 600N stock gearing for this hyper?

BTW.....I see lots of smoke. Not like a good tune on my old r/c cars. (just a slight smoke stream)

As I'm sure you know, every engine/pipe set-up is different, but I'm running my low needle at almost 2 o'clock and my high needle at 1 click lean of 1.25. and that got my MP5 singing at 2050 HS yesterday.

Hell... I can fix that.

How long to you get on your tank. I was told I should be 9-10 mins sport. 7-8 mins 3d.

How hot is that motor running and how much oil mess do you get all over your heli? My LHS told me to stay around 170-180 degrees at the plug.

I get about 9 min of moderate 3D. I don't know the plug temp, never checked it. but at the bottom fin it's 195 to 200 and the back plate is usually between 135 and 150 depending on how many autos.

As for the oil mess, I'm using the align diverter and it does a pretty good job. But your never gonna keep all of the oil off.

Im not looking to get all the oil off. Im just saying when I take it home to clean it. I can easily use 5-6 paper towels and alchohol. What do you guys use to clean?

At one point I measured the fins at 225degrees. This is when I richend up everything.

@ 225 your gonna be alright. 240 and you need to worry. And if the oil really bothers you that much, then get a long exhaust deflector. Helicopters need the oil content to help in cooling. And, 91% alcohol from walgreens, or any store, works great for removing the oil.

fastest and easiest way to clean your heli....

spray it down with break cleaner. it gets all those wee little areas, great for washing the crap of the rotor head, bearings, clutch dust, ect.

a little pricy though, so i dont do it everytime.

i used to get 25 minute flights of hovering on my old Nexus 30...

i find though that after 10 minutes of 3D im ready for a break

electricdurango

what vital grease from what bearings? most have shields on them to keep dirt out to begin with. unless your shooting it directly at a bearing, it will be fine. other bearings on the rotor head for example in my opinion dont need grease, they simply dont see the loads and speeds some of the other bearings see.

the only bearings i have ever greased in the past 5 years of flying, are main shaft bearings, tail shaft bearings/gears, and the thrust bearings in the blade grips. everything else just gets a little oil.

Its info I remember from my old r/c truck days, Running on the beach or other sand pits, dirt etc....

Dirt sits in the seams of the bearings. If you shoot high compressed air directly toward the bearings it will actualy press the dirt into the bearings via the oil/ grease etc.

Not all the dirt, but some. If you ever do this religiously for all your cleaning sessions and then use a bearing re-greaser. Check out the goop that comes out of the bearing when pressed. Its pretty bad. I understand not all the dirt pressed out is from compressed air cleaning but some of it is. This can be prevented.

On the other hand I partly solved my engine troubles memtioned in the begining of this thread. My stock Align fuel tube had a crack in it. The one in the tank. This fluctuated the amount of fuel going to the carb leading to in consitent tuning. I have now removed all Align fuel tubing and replaced with Great Planes FT.

Damn. I still cant break the solid 6 mins a tank thing.

Running a 1800/1950/2100
OS 50 Hyper
MP5 Pipe
-11 +11

I took it back out today for more play time and tuning. Running CY 30% 23% oil fuel. I now have my screw setting about 2:00 and my HSN around 2 clicks shy of 1.25. Ill fly for about 4-5 mins at 2100 HS and then land. I can hold my finger on the backplate a long time. I can hold it on the head fins for about 5 seconds. When I pinch the line the RPM will increase in about 2.5 seconds.

I dont know for the life on me how people are getting 9+ mins of flight.

This is the whole reason I bought a 600N. I wanted longer flight times for more air time. It sucks that Im having almost the same flight time as my 600CF with a TP 5000 even though I would be lying if I said my 600CF was hitting 2000 HS.

OK. I took my engine out and checked the back bolts and head bolts. The head bolts I got about a 1/4 turn on each of them. I check this because after a flight I was inspecting my heli. I found some oil seepage around the bottom of the crank case and head.

Could this be part of my tuning/ fuel economy problem?

Its got to be something. I mean lot of people getting 9+ mins.
