Agreed! I put 2 1/2 ounces of lead in the vyper nose to get the battery moved back. I really need to move that rudder servo.

My Yak seems to lack power. I have the Omega 130 and Castle Ice Lite 50 with a Zoar 13x7 using 3s Thunder Power 25c 2100 battery. Just watt metered it and it settled 360 watts and like 35 amps. Is this normal? I have a Zoar 14x7 I can try. Will that make much difference? Should i change the timing? Motrolfly it?

Did you do the Fixed Endpoints Throttle Setup for the ICE?

Also, I ran 130's on High Timing, Fast Acceleration.

Should be seeing like 420-500 Watts, 40-50A depending on prop and settings.

Use the 14x7. More prop will pull more watts from the motor.

I only run a Xoar 13x6.5, has plenty of speed and power, on a Motrolfly. But flew it on a 130g also.

For me, proper setup first, then play with props for the feel you want.

How well do your packs hold voltage under load? Low "C" packs or older packs won't hold high voltages under wide-open throttle, resulting in lower wattage......on a fully charged pack, under full throttle after 5 seconds, what is your voltage? Amps? Watts?

With full power from the ESC, on good batts, I'd expect more wattage?

Where are you located? What altitude?

Got it working better! Didnt watt meter it but I threw on a 14x7 and hooked the castle link back up. I didnt see the save settings button in the corner when switched it to high acceleration the first time. Now she will climb straight outta sight in no time at all! Rollers are smooth as glass with this plane! I was able to fix the leg on the landing gear too. I used some ca hinge material that came in a sheet and wrapped it tight while tacking and soaking it with ca then hit it with a black sharpie. It even held up to a bounce! Funny the other side never cracked.

if the packs are holding ok can always prop up if amps and heat doesnt rise too high..
Never,ever can go wrong by motrolfly'ing it either.
