Which Engine On Baby Ringmaster

Hi all. Hoping to get to put up my Baby Ringmaster this weekend, just that I have to pick a powerplant for it. I have a couple of options.
1. Babe Bee with head modified for standard short plug. Runs, but not 100%. Keeps the Man-Win Trainer #1 out on 35 foot lines ok. Picture taken before being finished and flown.


2. Babe Bee with hole in tank for remote fuel tank, currently living on Man-Win Trainer #2. When this thing runs, it is scary at how she revs. But man does she go. Pulls its ship around on 35 foot heavy lines (unknown type string).


3. Product engine/Sure Start. Currently residing on a 1/2a Circlemaster. Runs well. Had some problems with it earlier in the year while bench running it, but that was corrected in an earlier topic. Just needs a new fuel line and tank is rebuilt. Same tank as that on Man-Win Trainer #2.


The only Ringmaster I have flown in the past is a Beginner Ringmaster with Black Widow. It was fast, and am not looking for that now. This model will only be flown by myself and nobody else. That is why I have the Man-Wins. And they are a hit. Many have tried and a few have been able to fly out a tank. It is always fun to watch someone else fly it. Anyways, just looking for your suggestions and opinions. Thank you.
