Since I have no build my Magnum yet. I decide to make breaking to the West 50V1 Engine thats come with the Magnum.
I mount the engine in a 40 size airplane with header and pipe.
The Gap between the Header and the pipe was 1cm
Prop: 10x6 APC
Fuel: Morgan Omega 10%nitro 17% oil
I add some ounces of Klotz 100% synthetic oil to the fuel
Glow Plug K&B HP
I Do 3 10 ounces tanks breaking.
I got 17,000 RPM with this set up
Why I only got 17,000 RPM?????
Do I have to use 15% Nirtro????
Do the Gap between the Header and the pipe has something to do with this?????
The only bad thing I can mention about the engine is that is was LEAKING fuel from the front bearing
I think this is a trade mark of Webra engines because I have 3 Webras 50 GT Speed engines and the 3 has the same fuel leaking problem on the front bearing.
I dont understand why they dont put a sealed bearing on the front??? Do any body has a clue for this?
