I know I'm looking at 2100-2200 3-cell LiPo battery and have been told I need at least a 15C.

I'm very new here so chime in with all kinds of recommendations.

I currently have a Himax 4100 setup with a Phenix 25 ESC and a 1200mah 11.1 LiPo -- my foamy flying set.

What do I need to give me Ultra Stick performance from my E-Flite Mini Ultra Stick? Give me alternatives. I know virtually nothing about outrunners and virtually nothing about what I even have.

When I first got mine I used the receommonded eflite 450 motor with a 20 amp ESC and a 2100mah 11.1v battery. I wasnt very happy with this as I felt it was a little sluggish I could go vertical for about 50 feet then it would roll off to one side. I recently up graded to a eflite 480 35 ESC and a 11x3.5 prop same battery. NOW I can go vertical until it goes out of sight at half throttle. I LOVE this set up. HIGHLY HIGHLY RECOMMONDED setup.

I concur with fireplug. I have the Park 480/910 outrunner and APC 11x7E prop. Boatloads of power

I'm running the Hacker A30-28s, X-30 ESC. 9-5 APCE. TP2100mah 3s lipo. Take off run is about 8 feet and then straight up as far as I can see. Waiting for the next size up to come out. Ken

Your take off is 8 feet. you mean 8 inches right..... I can get off the ground in less than a foot. Full up elevator and the full throttle and wham its airbourne in 8 inches.

That's right ! Now if they just come out with a .40 size

For those of you who are flying the Ultra Stik-E, I have a question. This is my first electric airplane with a brushless/Lipo set up. This is what I have put together:
E-Flight Park 480 910Kv
E-Flight 40 amp brushless ESC
E-Flight/Thunder Power 11.1v 2100 mah lipo batteries (EFLB1035)
APC 11x5.5E prop
JR R610M RX
(4) JR NES-241 servos

My question is about the servos. The instructions for the speed control indicate that you can use 4 servos with a 3 cell lipo, BUT if the servos are economy class servos you need to reduce that number to 3 ??? Is the JR NES-241 considered an economy class servo?
A good friend of mine had the exact same setup as mine, except that he used Hitec HS-81 servos and suffered a loss of control twice. The first time was repairable, the second time destroyed the airplane. I was wondering if the current draw from the servos may have caused the problem?
Been flying R/C for over 35 years so I am not a novice, just new to the brushless/Lipo technology. These new electric power combinations look to be great power plants for some of the older vintage designs.

I dont think his crashes were from the servos. Im using HS-81s in the wings and two mini gws servos for the rudder and elevator. Im not sure what servos the JR ones are however if they are mini servos they will work. I'm using a standard size Futaba 7 channel rx as I have had problems with micro receivers. If you use the set up your talking about it should fly great. Servos work on a voltage in the area of 4.8 volts and the bettery is 11.1 volts the ESC will drop your voltage down to the 4.8 volt area.

I did a little page for the Mini Ultra Stick on my website. Tells which motor, battery, and prop. It's a real performer with this set-up. You can see it here. http://www.toddsmodels.com/Reviews/M...ultrastick.htm

Excellent tutorial Todd. I found just after I completed my MUS. Coulda used at least one of your tips from it.

I hadn't thought about putting the speed control outside to help with cooling, good idea. I still have my brain programed to deal with exhaust residue[sm=stupid.gif].
