Hi Dar,

I bought the silicone hose, original length 2.5", the new one 4.5", the original distance between the elbow and the silencer was 1.25", the new distance is 3", I increased the distance 1.5" between the header and the silencer, do you think is it correct? I haven't started the engine I'll do on sunday, so I don't know if with this new length do I have to tune again the engine I mean, would I see any change in the behavior of the engine? or this cahnge just avoid the burnt of the glow plug, does the transition will continue working properly? I know, there are a lot of questions, so I'm so sorry if I bother you.

Finally, if everything goes well, If I change the propeller 11x6 to 12x4 as you said before, could I hang the airplane from the engine, I mean can I do a hover?

A friend told me that I could fix the transition problem if I increase the diameter of the carburator hole in 3mm, the actual diameter is 7mm that is 10mm after the change, is it true?

Finally, thank you very much for your help and information, it has been very useful to me.

Regards,

Ricardo
