Here is a list of my current set up

600N Sport Kit
OS Hyper w/ Align pipe
9451's all around
GY611 w/9256
Multigov from Aerospire w/9452
Fuel Magnet
30% CY
2 in 1 regulator with 3400 2S TP pack
440mm flybar w/ stubz
CY tail blades
Align 600 GF blades
Align metal fan
2100 HS
+-14 collective, 9 cyclic

My question is my backplate seems warmer than it should be according to RR posts I've read. About 3-5 secons with light pressure on backplate. However after about 10-12 flights I drop my engine to see if there are any signs of me running it too lean, but it is always looking like new condition. No signs of it being run too lean. So I guess what I am asking is, is it normal to run hotter than the norm without ruining my OS? If I try to richen it a little than it starts to bog at times. My engine seems happy at this temp and like I said previously it shows no signs of running too lean.

Maybe a good candidate for the 3DX metal fan. Need the extra cooling for the type of weather we fly in. And if you do order one, order one for me too.



Why buy?? when you can borrow and no return

The field at which we fly gets pretty dang hot, no matter if its summer or not, night or day. I am trying to find a fan that can keep my OS running cooler than it is right now.

3DX.........Gforce etc.........

I use the G-Force SHO. Works well in the temps here.

What plug are you using?
30%CY requires a very cold plug.
An OS#A5 would be best for your setup.
If the plug is cooler, the ignition is later and you must turn your engine richer to get the right fuel/air mixure.
Richer=more oil=cooler

I run the dual bellwood head on my os 50 and wanted to know if I needed to switch to the os#5 as right now I am using the os#8 plugs. I am not sure if my elivation in CO has anything to do with it. Thanks.

It is not an exact science.
Generally 30% Nitro on a 50 => OS#A5
With less Nitro you can suffice with a hotter plug like A Enya#4 or a OS#8 (Enya#4 is slightly colder).
It also depends on humidity, height etc.....
The only way to know for sure, is to try it.

I run the 3DX fan here in the Az desert. It works fine at 115F during the summer.

If the plug is colder the engine will need a leaner mixture, that is one reason to use a hot plug, you can have a rich mixture and still ignite the fuel mixture at the correct time, which is maximum force around twenty degrees past TDC. The plug will be the same as most of the rest of us use an OS8 or Enya3, the result of a higher elevation will cause less compression in the engine and that will delay the ignition point so a hot plug is in order.

Darn it then, guess I have to buy some #5. I have a whole packet of #8 that I think is a little too hot for the 30%.
I will be installing a Carbsmart as I just ordered it last night. My engine leaned out after some mild 3D.

Thanks for the info.....

Airdodger,

Sorry dude, I did not get to read your post until I posted my last one.

What temps should I be at on the back plate and head?

Airdodger is right in a way.
You need the hottest possible plug possible for your setup.
But this is only correct if the correct ignition timing is there.

Suppose:
Your plug is too hot.
Ignition will be soon.
The amount of air and fuel must be in the correct mixture.
Is the ignition too soon? then less air is in the carb -> less fuel required for optimal mixture.
So if you tune the engine for optimal performance = Hot engine
Tune it for cool engine = no power.

Your plug is too cold.
The only way to get the right mixture to this ignition timing is to set the engine too rich. But then the timing is off.
So if you tune the engine for optimal performance = pre-ignition (metalic rattle)
Tune it for cool enginge = no power, sluggish

Ignition timing the key here.
You need to find the right plug for your setup.
Another way to change ignition timing is using shims....

Basically:
50 size and 30% Nitro = OS#A5 in my experience.

Hope you guys all remembered to factor in that I am at basically sea level and where I fly my avg temperature is around 82-89 degrees.

No, thats why there is no 100% answer.
You have to test different plugs in YOUR conditions to see what's right for YOU !!
It's not an expensive test and it can be very with very pleasing results

I thought 99% used OS8 on their 50s
