Well today was the day. After much frustration with the Saito 170R3 (now I remember why I haven't used it for several years), I got some air under the Waco's wings. The 170 has far more power than the model needs, even when it dropped a cylinder, power was more than enough. Even though I'm using a Sonic-Tronic's on-board glow, the engine kept dropping the cylinder that's at the 7 o'clock position (looking at it from the front). I'm using a 4-cell 4500 Nimh and it's not giving out enough amps to keep the plugs hot enough. Does anybody have any suggestions on how to keep all 3 cylinders lit?

Here's some pics.
