I picked up the BP Camel a month or so back. It looks like a well made kit. I only made a a few changes. I made it so a 2000mah pack will stand up against the firewall and moved the servos further forward. I also made a tail skid.
1st maiden was not good. Think it was too tail heavy. I did get some semblance of control then I ran it into a pile of gravel. Wrecked the landing gear and cowl.
I made a new cowl by forming a pop bottle over a foam mold and made new gear and wheels. I added some lead to the nose so I hope the 2nd maiden goes well.

I like the tailskid. Is that the new cowl and landing gear too?

Sorry to hear about your maiden; best of luck on the second.

Yes, That is the new cowl and landing gear. I am still waiting on a good morning to make the test flight. hopefully next weekend will be better

Since you're already into making cowls, I'd just as soon trim a cowl short to look proper scale, even with the motor sticking out a bit. The stock cowl is far too long. Along with the detail you added, you'll have by far the best looking BP Camel. The red cowl allows another cheat, as you can paint the rear of the cowl silver to match the fuse, and give the appearance of the cowl being shorter. If you really want to go all out, then remove the access panel stickers :D and add raised access panels of scale size to the plane. Pardon the scale detail ideas, as I had thought of getting one of these before building my Camel, and had also though of what I would do with the BP Camel.

I would not be afraid to add lots of lead to the forward most area inside the cowl. The Camel has a lot of wing, and the weight is not a problem. The manual CG settings are generally aft, and often non-flyable. My Guillows Camel was lucky to not be destroyed on the maiden. Adding more lead made a beautiful flyer, that is stable in rolls, etc. Straightens itself right out. The CG is something like 10mm from the leading edge of the bottom wing. If I remember correctly, at a mere 5mm back, the plane was unflyable. Looking at the size of your plane and scaling off top of head, I would imagine that somewhere between 15-20mm from the bottom wing is where you want to be. Don't worry about adding a ton of lead to get there, as you have twice the wing area of a monoplane at the same size.

The forward staggered top wing is a trap with CG on WW1 planes. The CG is likely to be a lot closer to the top wing LE on a forward staggered wing then most of us would like to imagine.

Cool pic Bill

thanks for the info. I will re-check the cg before the next flight. If all goes well, then I will make some scale changes such as the cowl and firewall adjustment.

Sence the Camel needs lots of weight forward I fly my Wattage Camel on Nimh batteries mounted in an upside down U over the brushless motor. The Nimh adds more weight than Lipos. I also used mini servos installed just behind the fire wall with pull-pull for the controls saving weight on the tail. I did not have to add any extra weight to get the COG correct.

Same idea here. My flying buddy has my old Wattage Sopwith and just flew it the other day. Servos directly behind the firewall. It uses an EVO 3s-1320 stuffed in the cowl alongside the geared motor, and still has quite a bit of lead in the cowl, along with 7 Williams Brothers radial cylinders glued to the cowl front. Couldn't physically fit 9 of them.:D

I must say, I just got this kit off of ebay for 85 bucks and didnt really expect much but wow was I surprised! It is a real nice kit and looks great! the quality seems great too! Seems to be a bit of an unknown but great value!

So prior to me doing a maiden, has anybody confirmed the CG location when using a stock 1300-1500mah battery? Would hate to crash it first time out.

I finally got to try flying this last weekend and found it to be uncontrolable as setup using the CG as marked and a 1500mah battery. I luckily crashed fairly gently and only had to repair a single strut.

I have since added some weight to the nose but it still seems like it is tail heavy. I am used to balancing out ww2 warbirds, but I am a bit of a newbie on the WW1 planes....

how far back from the lower wing leading edge shoudl the CG balance point be? if you cant use the lower wing to balance, then if I flip the bird on its back to balance off the upper wing, how far back from the leading edge of the top wing should it be?

Your help is appreciated....

My Wattage Camel balances almost at the leading edge of the lower wing. I balance my planes on the upper wing with the plane upright.
