Some progress. The rudder will have more authority, also ailerons, it was a 3D kind of modification.

Built the cowl from the three parts. Fit it to the plane with the engine. Then get some medium weight fibreglass cloth and ZPoxy finishing resin. Roughen the inside of the cowl with sandpaper and put two layers of cloth in convenient pieces covering the complete inside of the cowl.

It's a fun project and has worked well for me. If you bust up that cowl in a crash you can replace it with a fibreglass one.

Status: offline 		HI all, I have built 6 CG 300's and I'm just about ready to cover my newest back up plane. I love flying my 300 with a Saito 180 turning a 16/10 prop. I feel their is no need to enlarge the rudder, just add more throw and use a 100 oz servo, I can knife edge all around the field , that really impressess the other flyers I use a 16 oz tank for fuel and pce the tank pretty close to the CG. I use 2 servos in the tail for the elevator and a 1400 mah battery and everything balances.
I also place some carbon fiber on the weakes place on the plane, I"ve had it snap in half on a not so hard landing.

Status: offline 		Here's Mine all finished... picking up some wheel pants in Toledo next friday. Has a Tupertigre .91 and JR radio. Used a 13 ounce graupner tank in it. What prop should I use on it ? Suggestions ? I just tossed on a prop for the pics so it would look ok. Need to run a tank or 2 thru the motor and give it a shot here soon !

RC Pete,

Do you have a picture of your tail elevator servos? I need to mount mine in the tail. I am anxiously looking forward to this plane.

Status: offline 		I maidened my Extra yesterday, and put three more flights on it today. It is really a great flying plane. I ordered the Graupner tank from Hobby Lobby. I am using an MDS 1.48 (17x8 apc) for power. This gives me unlimited vertical.

Does anyone have a good suggestion for some landing gear to keep this plane from nosing over?

Status: offline 		Hi Guys,
I've just brought my self a damaged CG Extra 60, which I'm rebuilding, one question though, who covers, and who paints.

The original model was covered then painted, its just that I've always covered my models in solar film.

Pros and cons of both??


Thanks for any help

Antony.

Status: offline 		Question about engine installation. I am going to install a YS 120 with a pitts style muffler. I was planning on installing it inverted but looking at some of the pics with engine installations, they are all at a 90. Will there be a problem mounting inverted?
