Yeah, Rat was out of hand.
At 135lbs soaking wet I built engines and pitted. 5-6 lap test flights and then the shut off was about all I felt Ok doing. Heck a slip or trip and I might wind up lost in the next county.
In the 60s George Cleveland tried to get me to fly one as a jr at State Champs one year. Took an entire day to convince him that at lap 6 I was going to hit the shut off.
We would have won as the airplane had about 20mph on the other jrs. I'm chicken.

Here is a pic of some sort of Quicky type Rat built in the 80s by a friend after I quit flying. I think they were using combat engines then.
Strange engine rules for current Quicky Rat.
The K&B 40 is engine of choice from whats legal. As they slowly blow up others will replace it.
Notice external controls. I think this is a requirement.

Sounds like you knew some of the old bunch.
Stub and Buckstaff are 2 that come to mind as they were my main competition and one of us 3 usually had first place.-there were others. Great guys and good times.
Stub and 4-5 of the others still fly combat!!
Buck is gone.
