I haven't attempted to estimate final weight yet, but going by the overall size, I'm hoping my OS Engines 55AX will provide enough power.  I'm going nitro as opposed to electric primarily for duration, but I think electric might be a little costly at this size as well.

Paul, last April you sent me links to the files.  Are those links still pointing at the latest versions?

Very nice progress, so far.  Not sure if this got lost in our communications, but I have a 12X20" laser cutter if you need any work done.  It's a hobby thing, so I charge very little for it's service.

Hi John,

I just updated the Pioneer.zip file with the latest design files.  I made one change during construction that is not reflected in the plans (although it's shown in the "VisiblePioneer" file.  I moved the firewall one inch forward to get it out of the fuselage curve.  I realized that curving the fuselage sides in that area would weaken the structure--not a good idea at the firewall!  I'll put all of the curve in the tail cone.  I'll have to extend the motor mount to compensate if I want to stay to scale, but I found that putting the motor that far back allows a standard muffler to fit.  There are two other changes I would make, but it's too late for me.  I went with the heavy gauge aluminum for both the landing gear and tail boom tubes.  It was overkill.  The lighter gauge in both cases would have been fine.

Let me know if you need the download links again.

Thanks,
Paul

Hi Paul.

The UAV that you have been working on looks absoloutely amazing.

I was wondering if we could have a chat, has I would like to talk with more experienced people about a certain amount of topics, and from the work you have developed, I see you as an ideal mentor.

Best Regards

Hi Paul,

I just found this forum and love your UAV. Have you flown your RQ-2 yet?

Could send me the links to your drawing? I would love to try and build one.

@Dinis -- Somehow I missed the notice of your comment.  My sincere apologies for the long delay in responding.  I will send a friend request, although my now you might have received the help you need.

@Kray -- Thank you for your comments as well.  I will also send a friend request to you.

Paul

Hi Paul,

I just saw the forum and also your drawings. I am a graduate student and studying for my thesis project. I really need the detailed dimensions of Pioneer RQ2 since I trying to find aerodynamic coefficients of it. I have been searching for a week but unfortunately there is no information anywhere. Did you use the real dimensions of it (is it just a scaled version with %42) while drawing? And Could you send me your drawings and if it is possible, could you send me the detailed dimensions (the dimensions about its CG, wing, body )of the UAV?

@Ilden -- Thank you for your note.  My Pioneer design is based on data from the real Pioneer including all dimensions and airfoils.  I'll send a friend request so that I can provide additional detail.

Thanks,

Paul

Hi Paul,

I am interested on your project and I would like to build my one as well. Could send me the links to your drawing?
