You had me worried there for a moment since I hadnt tested that obvious aspect. Pheeew! fits no problem. Even if not I could have assembled it in the nose without too much trouble. Eventually I will make a clip in box for various payloads like Thunderbirds #2

Ha! Yeh, it's only now I'm a little older that I wonder how DID Thunderbirds 2 ever fly with those wings!

I was just thinking the same. Im also thinking the box tail wing is what the X8 needs. I have been doing some reading on how efficient it is.

I would say cut back to the first partition and create a collar. The collar would be a circular receiver for the "pods". The pod could have a standard connector of some sort to just plug and play that would handle things like
Power
Video audio, pan and tilt per camera in the nose.
Voltage, ground and signal connections that the user could configure for whatever.

The collar connected to the payload by whatever method, a Velcro collar about 4 cm wide (2cm for body and 2cm for payload) going all the way around seems simple and easy to install.

Also it would mean that your investment is protected, after all most incidents that result in damage are to the nose as aircraft vaery rarely reverse into hills hehe.

I am waiting for my airframe to arrive but as soon as it does I will put some sketches up for discussion.

This way rather than have multiple x8s you could have one that is multi mission.

I am investing a lot in my base airframe with retracts autopilot etc etc so I want to be able to leverage that investment for the most fun

SO much effort!
Hope you sell some for all that time mate.. Just hurry up and get building!...

Prop

All,

I went through the "Beginners Guide to Motor and Prop Selection" - http://www.rcgroups.com/forums/showthread.php?t=1136470

It and WebOCalc tell me to use large props with almost every motor I try. Most say 18x10 or so.

But I don't see anyone using props that large. I have been reading a lot, but I still don't understand why people are not using larger props and what the difference will be.

Anyone help?

Thanks in advance!

Most use around a 13" prop with great results, I`m using a 16" to try get longer flight times on lower Kv.

So far the weight is too much for a 16" to launch by hand and keep amps down if full loaded, a larger prop would be a bit naughty on your fingers for hand launching IMO.

Thanks, I feel more comfortable about gluing the body together now. It looks like you are only correcting for roll with your camera mount. I'm guessing that is probably all that is needed.
Would you mind sharing what you are using to control the autolevel? I was planning to use the APM2 but I thought I read somewhere this capability wasn't available yet.

What is your flying weight?

Are you carrying a lot of gear?
