looks like the eagle 1 using crankcase pressure on an r/c engine causes proplems in the idle and midrange,that fitting was probably used for a smoke tank.the carb adjust differently than anything used these days,do you have the instructions for this engine.this is a loop scavanged engine .

goirish

Don't know what loop scavanged engine means. Nope no gottem instruction sheet.

Use muffler pressure on the tank and cap off the other fitting.

goirish

AH!!! now I know what a loope scavanged engine is. That is the new thing I have learned for the day. RCU for increasing my vocabulary.

goirish,
your eagle 1 was setup for fuels up to 25% nitro ,all the other eagles were set up fopr 0-5% nitro.so your present fuel with the additional oil should be fine.set the low speed mixture first after cleaning the carb and all parts,pipe cleaners work good on the passages.the other alternative is a perry carb.the eagle 1 will swing a larger prop than the other eagles.

boy am I glad to hear that I don't have to buy special fuel for just on motor. Is the castor oil just regular castor or do I need to get it from the LHS. In my case not to local. 1-1/2 hrs away. Thanks for the manual info.

aerowoof

it needs to be degummed the stuff you get at the drug store will not work.lhs or mail order

goirish

Thanks, probably will purchase on-line--cost of gas for a 3hr trip has to be more than the shipping.

Great minds think alike--I just pulled up that at TH. Also went to [b] The R/C Aircrat Proving Grounds-Mixing Fuel. WWW.geistware.com/rcmodeling/mixing_fuel.htm

by those numbers 4 oz of castor added to your 18 % oil fuel will give just over 21 % oil.

If you have a local motor cycle shop you can get caster there And Duke told every on that Missile Mist was the best 25% Nitro

It is VERY likely that you are not setting the carb properly. As stated in a previous post you MUST set the low speed mixture first, unlike modern engines. This is because the low speed jet is always open, the high speed jet just adds to the total fuel mixture. If the low side is lean you will NEVER get the high side set, even with the high speed needle completely removed.

These are great engines, however many were ruined through improper carb adjustments before they really were broken in. This engine is very light and weighs as much as todays .46 engines but will really turn the lumber. It is indeed a screamer, especially on 25% nitro! You MUST add castor as previously stated. Mine is plenty strong on 10% Nitro. Use an 11 x 7 prop for break in then you can try a 12 x 6.

Be patient, this engine will take 2 gallons or so before it starts to break in. You may have to land a time or 2 during a flight to richen the high speed mixture to keep it from going lean as you burn off fuel. This will pass as the engine breaks in. I love Fox engines and every time I get a new one I become impatient and just about the time I'm ready to toss it in the junk box it starts to come alive. From that point on every flight is a little better than the last.

The good news is, it will likely last the rest of you life if run on the correct fuel.

Hello Goirish,

Your Fox needs to run with at least 15% Caster. From there you can use Synthetic added to that mixture of15% Caster, around 8oz per gallon. Brings you to about 21%. Here is the deal: Synthetic oil has only a heat range of about 150 degress F, Caster has a heat range of about 400 degrees, so if your carbarator is not adjusted just right, the engine will not stay cool enough or last much longer. Only 5% nitro. I repeat only 5% nitro, fuels are different then the where years ago, here is a link that can help you: [link=http://www3.telus.net/fliteline/fuelprops.html]Fuel[/link]

Once you make or purchase this fuel it will good for your Bushing Engines(ie OS FP) it will make them last almost forever.

Also there is a modification you can do to the carb to prevent leanout in the 3/4 range of the throttle - a common problem with Eagle 1's. 2fast is right about the carbruator adjustments...low first. Why the synthetic oil then...it keeps the engine parts clean, otherwise with just staight caster you will have to clean it inside and out once and awhile.

Here is a link about the throttle: [link=http://www3.telus.net/fliteline/carbs.html]Throttle[/link]

Anyway...happy flying.

Remember to keep your Fox clean! Thanks again Duke!
