Ive got a midwest cap 80, with bme 50, pcm fm reciever. Works/flies nicely. It has 1.5# of lead in the nose to balance at the midrange point...

I have read most every thread here on rf interference and pose this question. Is there any way to mount the battery close to the ignition?????

I mean, can I wrap it in foil, metal tape, lead , kryptonite, choke it, shorten /extend/twist/the leads, pray over it, perform an exorcism, any special dances, prostate checks, or other, so that I can remove the lead????

There just has to be a way...The previous owner had a US engine on it, with the battery mounted right next to it (magneto engine) with no prtoblems......

Am I asking for too much?

The ignition battery next to the ignition is a very good idea, keeps all the noise togather. The radio battery next to the ignition is a very BAD idea.
See if you can lengthen the mtr mount and move the engine futher ahead, maybe needs new cowl. Or maybe move the wings back.
This is the down side of the very light BME engines, the only way around is advanced planing when selecting the plane.

I am in the same boat that you are. I picked up a Giant Stinger from a buddy that had a US41 in it. I am replacing it with a Sachs 51cc conversion. It takes 1.5lbs of lead to balance on the money. I ended up replacing the aluminum standoffs on my engine with longer ones made of Brass. It added the needed weight while shifting the weight of the engine farther forward. I ended up adding about .75lbs instead of the origional 1.5lbs it took.
