First off I make sure that the engine is warmed up really well and then I look for around 3000 rpm to start. I may be able to get abit slower but I don't want the idle to be any faster if I can help it or it makes the landings faster than they need to be. Btw, fuel with 10% nitro is a good all around fuel to get as long as it has 18% oil content. I like a mixture of 50% Castor and 50% snynthetic oil. Its called Sport fuel. [8D]
Youhouuuuu!!! I got my problem solved!!!
The engine is back to perfect operation now, and I am less stressing at landing and take off and all manoeuvers
It is just that I trust the engine won't quit on me anymore!!
What I did was simply break the zinger 11x6 propeller after a hard landing, and replace it with a handy APC 11x6. What a difference!! I immediately felt the engine running smoother, and quiter. I did some flights with it and it was so nice, I started cursing the zinger one
Another pilot told me to try an 11x7 and he offered me his master airscew. WOW!! That was even easier on the engine, and btw I love the 7in pitch, the plane handles so nice!!
I am now idling at 2500rpm, and reaching 11000rpm at WOT. This is on 5% nitro, #8 glow plug and 16% castor/synthetic blend.
The idle is so nice, I just need to be a couple of notches higher than idle to land the fourstar and then drop it quickly to idle for taxi. The plane can even stay stationary on the runway if I leave it to idle. I love it this way!!
The engine sound now is very sweet, the exhaust shows a light white stream, and the response is fairly quick. I think it is perfectly in tune now.
