I was running my Webra today in my Raptor an it was running at 235 degree's. The motor is still only in the break in period and really runs rich with very little power. I richened up the High end needle and the temps came down a bit but I had to lean the lower end to get the heli to spool up. I am running 10% CoolPower and a regular TT upgrade muffler. I was told by more than a few people that these engines really don't show their power until after a few gallons but I am more worried about the temps. So far this engine really seems gutless but I heard these engines have more than enough power after the break in period! Any thoughts on this?

Well I am running a OS #8 in it right now and there is nobody locally here that sells 5% nitro. 10% is the lowest anybody sells in Coolpower.

YES, this is true........My best advise will be doing a bench breaking.

Webras engine are designed to use low nitro.............

You can lower the nitro by adding some ounces of Klotz KL-200 Original Techniplate oil to your glow fuel. This will also help you to give you more lubrication during the breaking period.

Also you can put a Shim in the head so you can use 10% Nitro.

Good Luck.

Isaac thanks for the advice. I thought 10%nitro was low nitro? It is hard to beleive that they say this engine will produce more power than a OS when running such a low nitro content! I have and always will add Klotz to my heli fuel just to be safe. Actually I have done this on all my Nitro fuels for years and luckily I have never had a engine go bad on me. I think I will just run it a bit richer on the top end and just keep running it and will have to see when the power starts to come on!

In Europe the Nitro is expensive. It is for that reason that the UK makers of RC engines design them so that they surrender the biggest power with 0 or 5% Nitro.
In fact the Webra are hi comprecion engines . The hi nitro also contributes to preignicion and this goes up the temperature in the motor.
You can put a shim in the head and this will lower the compresion so you can use 10% nitro.

Why dont you try with other cold or hot plugs maybe you take yourself a surprise. Try some Enya 3 or 4.

Why dont you make a bench breaking???. I know is Pain in the ass to take out the motor.
Because maybe this over heating can damage the conecting rod or the engine.

Bottom Line is that Webra engines are a pain to pass breaking like a
1 1/2 gallon. But them they have a incredible power.

You dont tell in your post if you have a 35 0r 52 Webra. If you have a 35 Red head Webra this one is a competition engine and it
HI HI compresion engine.

Yeah thats the engine but mine has the newer black head on it. I think I will order the shim since getting 5 or 0% nitro isn't going to happen here. I will also try a colder plug to see how it runs!

I am not sure about the liner. I was told it is just a newer version but who knows for sure. Webra claims it to be their most powerfull 30 class engine.

Here is a link to it

I check the specs on the Speed .35 Black head Heli Competition

and they say it can use 15%-30% nitro heli fuel........Maybe this engines have alredy shimed to US Spec.

Can you get Omega 5% nitro fuel??? The Omega is Castor Synthetic blend. And Castor oil use to help to lower the temperature.
Also you can use other Castor Synthetic blen fuel like Byron, etc

If you use Castor Synthetic blen fuel, You can add some ounces of Klotz KL-100 Super Tecniplate Oil
the KL 100 is 80% Synthetic and 20% Castor oil.

The KL 200 is 100% Synthetic

I have 3 Webras 50GT Aero Speed in diferent planes and I am using
Omega Castor Synthetic blend fuel. with good results.

The only negative thing I can say about it is it leave some varnish in the engine.

Also if you want you can order a Back Plate cooling for you Webra.

The engine you see in the picture is a Webra 35 Modified by Weston UK.
I thing you can get the Back Plate Cooling in USA from
http://www.modellbau-usa.com/

I recently order from modellbau-usa a West 50 (Webra 50) . It has 2.8BHP at 23,000RPM with tune pipe.

Man I never looked at the specs on this engine! Surely running 10% which also has a smaller amount of oil in it is most likely the reason for the high temps and the lack of power even though its not broken in yet. I had a feeling that this heli engine was a bit different than the older red head which used lower % nitro but I just went by what everybody said about them and used the lower nitro content. I will bet my heli that if I ran coolpower 30% it will run cool as can be and have a ton of power! I will try 15% first and then maybe move to 30% later once I start some 3D. Thanks for pointing out the specs!

Isaac, Just a little update. Went to the field today with some coolpower 15% and ran the heli. Still hot...235 ish. Then I decided to try something, I took my fuel filter off and blew through it and guess what it leaked like crazy! I threw it out and installed a T fitting and capped of the open end. As soon as I started the heli it was running different. It was a bit rich with little power like the other day except one major difference, the engine was running at 175 degrees instead of 235. I am going to do some more flying tomorrow and I will let you know if it stays cool when I lean it out a small bit for a little more power.

Son of a gun! Does filter sooner or later they always give problems.

Since long time I dont use filter in my helis. They only has give me trouble.

Also dont be in such a hurry for lean the engine...... Take your time with this baby

Always use a filter to the pressure line and don't use any filter to the fueling line. I filter the fuel by using 4 filters in a row during the refueling process. I faced similar filter problems in the past and IMO is the best solution.

Just a update on the Speed 35. With a little over 2 gallons of coolpower 15 the engine had more power than I need at this point. It just woke up one day and has been running stronger and stronger ever since. I say with another gallon of fuel it will surpass the OS in power all together! I have my pitch setup at -9.5 to +9.5 and the engine has no problems with either. The only bad thing I have noticed so far is that the headspeed has been a bit high, over 2100 to be exact, but if I richen up the main needle it will bring the speed under 2000. I wonder if the Raptor 50 gearing would work with this engine or not?? This is by far the best running heli engine that I have run, the idle is great, power is good and it is very consistant.

Try getting a real muffler and itll REALLY wake up, buy a 50 size hatori. Or whoever's brand you like best.

Buzz, I am a little confused.......Why would I run a 50 size muffler on my speed 35? Am I missing something? I use the Raptor upgrade muffler right now.

Most 30 size mufflers dont leave enough "breathing" room for the engine, and getting a muffler that is a bit larger is better. If you do it, you will see. If you buy a pipe, and you get a 30 size pipe, it will be small and will give you troubles. I find that the 46/50 size pipes and mufflers run the 30 size engines alot better than the 30 size mufflers and pipes. I had my nexus with a standard muffler on it, then i got a hatori knockoff that was for a 46 engine. And the engine had so much more power, I had to knock back the throttle 10% to get the same headspeed. I was running my 46 today, and i used a 50 size muffler and it had more power than my 46 PIPE, then when i got someones 60 muffler, it had more power then both of them. Im telling you, you have to take the muffler size with a grain of salt.
