How are you at 3D?? Can do rolling circles yet?? Will bondo fix that hole in the wing?? Did you know that a Nelson venturi & needle will fit right in the hole of a Jett 60LX and max out the rpm scale of the tnc tach pushing a 8.5 X 8 cf apc. wheee May just pull that out of the Avi-Star. ENJOY

Status: offline 		LOL,

Roger, I have a Jett .35 on my Tribute 4d that does the best rolling circles, but I'm not the best 3d flier as I do ALL of my maneuvers at Full Power. I have been known to do rolling circles with a Quickie after a good race

It would take a lot of Bondo to fix that hole, I'll get it cleaned up nicely over the winter. I was not aware of the needle compatability, but you definately won't catch me flying an "avistar"

Status: offline 		rmenke for something the size of a miss ashley you would want a LOT more power to get or surpass nelson performance. My first E-powered pylon project was a wildhare LR1. I used mega's biggest motor the 36/30/3 and a 6S 4200 pack. It pulled about 65 amps on a 7x7 prop. This setup was good to about 138ish on radar doing level passes running a flat circular course. Out of a dive 150+ was easily attainable but I dont' consider that real world performance. I tried to prop up to a 7.4x8 Q40 prop to get some more speed but this pulled 80 amps and at 6S voltage it cooked the Mega motor good in a single run up test. The 36/30/3 is a real big motha too. This thing was really heavy for the wing area and it was a nightmare to land. 36oz/sqft loading.

The next project was a Royal Models Trick. This thing had a crazy fat draggy symetrical wing. I mean hella draggy it was litteraly 1" thick. Big ol Aveox long can 36/30/2, CC125 controller, and Hyperion 6S 3700 batteries. I ran a 7x7 prop on this as well. The first time I ran it up it was a frightning ammount of power. It was insanely loud. It was pulling 100 amps settling to mid 80's at 21 volts. In an honost straight line it was mid 150's despite the very draggy wing. Out of a dive it was doing 170+ easily. For giggles I put the plane on course with a Nelson powered Q500 and they were fairly close in a straight line but I had a lot more exit accleration. So clearly to me 2000 watts is the point where you eclipse nelson power.

Now that Neu makes a low turn high voltage motor (19 series) I want to do a 12S pulling about 60 amps. If I can find an airframe that is pretty sleek compared to the Trick was this should do an easy 180.

None of the built in Controller BEC's are good for high voltage. Castle creations now makes a very good cheap BEC as does UBEC. Just google it and you will find a source for them.

Status: offline 		kAL: Thanks for the info. Will look into the Castle stuff and see what I can find. The Mega motor and 4000mah battery go into a multiplex fun jett. Recent article has the setup in the 130-140's with good stability, just had to try one. Would probably sell my soul to outrun DN and some of the real fast gang with a electric. I will get my local guys with around 140mph if it will grove on a two pylon course. Apparently some of the other guys are getting close to 200 out of this thing with other gear, but have not found anything on line as yet. Think 140-150 is about all I can handle with the small size of this thing and my deteriorating eyesight. If nothing else, will scare um all away. ENJOY Bro 119

Status: offline 		Just ordered one of these things. I really like the concept (bare fuse & wing cores) ....I seldom build anything "straight from the box" anyway. Not going to race it - just go fast. I've flown mostly electric the last 5 years, but our club recently acquired a new field (actually and old private airport) with a paved runway and all the open airspace you could want. Great place to fly fast slimers. It will have either a YS 45 or (if I can find the money in the toy budget) a 60LX . Somebody needs to post some pictures....if my kit arrives soon I'll get some up.

Its going to take you a while to build this bird, so take your time and save coin toward that Jett 60LX. Its well worth the time and effort. Gonna be a beautiful combo, idle like a stort engine and turn up almost to racilng engines rpm, 18-19,000 rpms is not peanuts. Nice part, you dont have to fly around WFO, throttle back when you want and just enjoy. Give us some build pics along the way and a flight repot, you will enjoy the process.

Status: offline 		I am still waiting for mine to arrive. Kevin e-mailed 2 Fridays ago saying he would try to ship it that weekend. Well I was out if town for a week and I do not know if it showed up or not while I was gone. I have no way of knowing weather it has shipped or not, or even how it shipped so I could track it.
I am not in a huge hurry, but it would be nice to know what is happening. I have only sent one e-mail but it has been unanswered. I still plan a build thread when it does arrive.

Status: offline 		Funny, I have been looking at the Zoomer for a year or so. I presume the wing sheeting would be 1/16th and glassed? Don't suppose the wing could stand up to G loads with just Monokote or Ultracote? I have a JETT .46 that needs a home.

Thanks

For pylon planes it is recommended that 3/32" be used on top and 1/16" on the bottom on foam. Glassed in the center. Carbon strips on both sides are a plus. 3/32" on top is for strength in compression in the turns.

Status: offline 		Personally I would route out the wing and goop in a carbon spar. Then vacuum bag the wing in glass or carbon and completely skip the balsa sheeting. Wing should be good to go no matter how hard you yank it at that point.

Status: offline 		Guys:

Remember, keep it light. Light balsa 3/32 wing, glass center section, few paint coats as possible. Mine started life at close to 4 pounds and flew very well. Landing gear blocks added
