i know in the manual it says to set thew cg from the wing root leading edge, how many mm's would it be from the wing tips.... BTW its a great lil plane, its so light compared to my other similar sized planes, and built well,....... the only couple of things i didnt like were the wheel pants and some of the hardware, but thats usually the way arf's are anyhow. Im done withe the plane and cant wait to maiden it, i just need to figure out to mount the deans whip antenna ohh yeah i goofed on the engine cut out hole in the cowling before i get flamed

I guess I am sorta old school and still flip a plane like this upside down and balance it on my finger tips near the fusalage. When I first flew the plane I ballanced it at 4.25 inches back from the leading edge. It flew fine and was balanced there for my video. Since then I rebalanced it at 4 inches (closer to the 103 mm the manual calls for (103mm/25.4=4.05 in)). I think it is a little less snappy (read as scary) this way. But it still does the nice spins and tumbles. With the tappered wing, I am not sure what the balance point out at the wing tips would be. Good luck and I look forward to your flight report.

I guess ill have to try your method, and ill try my best for flight report, im not a good journalist, so it probably wont be too much...lol hopefully i can get some one to film

i woke up extra early today, and too windy to maiden, i live some what close to the beach, and it only gets worse as the day goes on ...most of the time

well im back, i decided to go, sorry no video i went alone. It flew great!!! I wasnt how sure the wheels would hold up on the grass runway but they did ok. Its still somewhat nose heavy but even then the landing was kinda floaty. I did have one mishap, I neglected to give it a preflight inspection(didnt think it was neccessary, i finished it lastnight), and about three minutes into the flight i started getting brave and did some tumbles, snaps etc.... and i notice something got out of alignment, it kept wanted to roll to one side, then it went away, but i landed immediately and noticed the servo arm came off. Since it was supposed to be a quickie today, i didnt take any tools other that a pack of allen wrenches for the hatch, glow driver and fuel, in other words i took the bare essentials....... next time im taking the usual goodies, and be prepared for s**+ like this morning.
P.S. knifeegdes great!! if my thumbs remember correctly it pulls slightly toward the canopy......I feel very confident with this plane .... cant wait to take her up again
I noticed there is a servo slot in the fuselage for what could be a rudder servo, has any one put dual elev servos and pull pull on the extra? Its probably overkill, but i like knowing that both control surfaces are moving in sync under high stress maneuvers

has it been too windy? It flies great! Mine only needed a couple of beeps of up elevator, probably cuz its nose heavy.

Hello Everyone,
I purchased the blue one from nitroplanes. I just get it by next week. I have a OS .46FX that I am planning on installing with a Bisson Pitts Mufler. Any suggestions?
I don't plan to do 3D since I am a beginner. This is my second pane after the trainer. I also fly helis so I know that helps. Any recommendations with props (size and brands)?
What is the CG for sport flying?
Thanks!

getting mine in blue this week also!! I'm pretty stoked I plan on running a pumped Webra speed .50 with a bisson muffler, anyone got any weights for us im curious to see where everyone is coming out at for weight with the boat anchors in the front. I'm hoping for around 4.5lbs with mine. Hoping I can get her to 3d like my Extreme Flight Yak-54e or my Extreme Flight Mini 3D.
