Building a Guillows P40 . Its getting a bit heavy. With all the rc equipment it might just be shy of 12 ounces. Is this too heavy for a babe bee ? Might have to go with a norvell .061.wings will bee fully sheeted . fuse will not, the antenna is part of the canopy hold down system, Don't know if I like that or not . Any engine suggestions would bee helpful. Thanks Guys

While overall weight is important, I think wing loading is more of a consideration.  I've seen a Gentle Lady fly with a Tee Dee at over 25 ounces, but wing loading is a light 5.4 oz/sq. ft.

If the P-40 has a limited wing area, wing loading will be higher and make for a snappy airplane.  I'm not sure power would make up for high loading. One weight saver would be to set it up as A/E or R/E only.   

The plane in my avatar weighs around 20 or 21 oz. ready to fly and has 252 sq. in. of area -- around 11.5 oz/sq foot.  It flys well, but can be a handful in a spin.

What size and weight servos are you using? Why use 4 when you can use 3? I have used servos as small as 3.7gram successfully on smaller aircraft. They are apps. .75 inch x 1.0 inch x .30 inch. See photo. Can’ t add photo with iPad. Will edit edit entry with MacBook in a minute or two to add photo.

http://www.flyrc.com/wing-load-calculator/   If you can fly fast R/C the Norvel or a TD would work , i think ? You can use the calculator but i don't know hot to figure the amount of thrust you will need? here is a set up for ailerons like you would need to use  Guillows 4 channel RC conversion Ailero10 And the Plane is looking Good !

Thanks for the input Guys HD .. my 4 servos weigh a combined 2 ounces . the main weight is going to be in the battery. Hey Eric , I have flown airplanes in excess of 100 mph. but its been a while, thanks for the drawing , I'm using one servo per aileron with a y connection 1 for rudder 1 for elevator and one for throttle if i have a throttle.

Any updates on your build? I'm starting the FW190 with an electric conversion. I'm also thinking of using a gyro receiver to help with stabilization.

12oz will be on the heavy side, might need an extra strong bee to pull it. What thickness balsa did you use to sheet the wing?

Yeah, there is a lot I’ll do different on the next one, 1/16 is what I used. I’m putting a black Lynx on it. I usually build heavy. It is still a lot liter then most plastic planes and a more powerful engine . Well time will tell.

Some tips to save weight in the next build would be to use 1mm (or 1/32'') sheeting on the wing, and select the lightest balsa you can find. If you're not after a smooth, scale look, you can leave the sheeting off altogether, but if you do use it, you don't need all the ribs and other internal structures. One out of every three ribs would do nicely, in fact, I did a sheeted wing with just three ribs per side. Also, having wing spars is redundant, as the sheeting will take over the load bearing.
This will probably still be alright in terms of flying, but I find my heavier models tend to have poor landing survivability (doesn't apply if you can find some tall grass to nestle into).
