YAK 54 50CC - CG QUESTION
Back in June I received my 50CC Aero Works YAK . Between work and other things I've finally installed 5955's on all control surfaces, a DA 50 with a tuned pipe, Fromeco batteries/regulators (mocked up) , smart fly kill switch, carbon wing tube and carbonspinner, smart fly power box and now I'm ready to balance the machine.
The manual specs call for the CG 4 1/4 inches from the leading edge of the wing measures at the wing tip. With this CG at this location will the model be nuetral in flight or is the CG at this spec a little nose heavy?
Thanks
Chuck

RE: YAK 54 50CC - CG QUESTION
Hi I'm building the aeroworks yak 54 50cc plane with about all this items listed above. DA 50 tuned pipe fromeco battieries/regulators, smartfly and before installing the battieries/regulators and smartfly I usually leave those items out and with everything else installed to check the cg so know where position this stuff without adding any lead weight. Sorry guys but most of the planes I build in the manual it shows the cg at the fusealge so i can set my plane on the cg machine and know where im at. But the 4.25 @ the wing tip and with tapered wings I dont know where the cg needs to be at the fuse. I dont want to screw up anything so does anyone know what the measurement at the fuse would be based on the 4.25 at the wingtip so i can set my rulers on my cg machine and know Im right.
Thanks for any help.

Why not put the wings on a carpet with the wing tube in place. Mark each tip and draw a string to each tip mark. Where the string crosses the wing root rib is where it should balance.

Using a string as bgw45 said is the best way to determine the CG at the root.

Bill:
This is one of the planes that i am considering buying and putting a new ZDZ60 RV in. My first choice would be the DA, but I already have the ZDZ on the shelf in a box and from what I hear this aircraft can easily handle the extra weight up front. This might be a good combination for me to start in IMAC?
What are your thoughts on this?
Jim!
