FINALLY made it to the pond to do some test & tune with my jae .21. i ran it at our d-12 race in greensboro 2 weeks ago for the first time. literally finished assembling the boat at the pond friday afternoon. set it up exactly to zippkits instructions. i had never even started the engine, picked up the prop from jimmy johnson that morning on the way down to the race. fired it up, threw it in with a fat needle, the boat took right off, hit the pipe & ran straight & true as an arrow!! i built the boat right by the instructions, using all zippkits hardware. i am running a cmb LS evo2 ( black case) engine set up by jimmy johnson. he asked me what i wanted & i replied that i want a fast, driveable engine, NOT an off & on switch type of powerplant. he also did a 1450 prop for me. weight comes in at 4 lbs. 1 oz. complete, less fuel. i ran 6 laps to check fuel consumption friday, i am running the sullivan ss 8 tank & had about 2 oz. left after the 6 laps. i was happy enough with the results that i put it up until saturday for the races. last year i ran a sundowner ob rigger with a cmb .21 TT/gold head set up by rod geraghty. that boat ran low 60's, but was very inconsistent, due to having to be set up on the ragged edge to be competitive (short pipe, big prop & engine/lower way high). i did not want to have that type set up again. all i can say is the whole jae team has hit a home run!! this in a very inexpensive, easy boat to build & end up with a rigger that will compete with the best out there, imho. so far, it has exhibited NO bad habits. never fails to launch, turns on a dime & hands back .07 cents change. takes some left turn without waving the sponson at you & just plain hauls the mail. if my sundowner ran low 60's, this boat seems like it's close to 70. no radar or timing to prove it, but it is MUCH faster than last years boat, without the reliability factor. all of this is, in no small part due to jimmy's fantastic engine & prop work. the boat will come all the way off plane, & get right back up with no issues at all. i am running an andy brown billet pipe & 65/18 wildcat fuel. i started with the pipe at 8 1/4" & a very rich needle to get going. saturday evening after the day's racing, i cut the header & pulled the pipe in the 8" & went a little leaner. still had a shiny plug, just barely starting to pull the element. today i cut some more & am at 7 7/8", went a little leaner yet. it will still throttle all the way off plane & get back up, & seems (to me at least) to be faster still. pulling the last 2 coils out just past the face of the plug, just starting to lose the shine & show some slight hazing, but not frosted or dull. i wish i had more time today, i think i can get the pipe down to 7 3/4" B) . still pulls jimmy's 1450 easily, the prop is 48 mm diameter, 3.6 (if i remember right) cup. i can say nothing but good things about this boat & engine/prop combo, & haven't really scratched the surface in tuning yet. still have some other pipes & props to test. i would like to thank all the folks that worked on designing, testing & producing the jae riggers, & especially jimmy johnson/rcracer158 for his excellent engine & prop work. all of you have made this way easier & more enjoyable than i ever imagined it would be. i have a feeling it's gonna be a fun season h34r: . like mikey said, jae .21, fun, fun, fun.
