Hi,

A year ago I was experimenting with a 6" F-18 Hornet, but I abandoned that project because I had some range problems with my IR setup. Now that I've been enhancing my IR setup, I took up that project again and made a new 6" F18 Hornet with some lessons learned from my previous experiments.

Here are some specs:

• Koichi IR rx (diff. thrust)
• selitac wings
• durabatics vertical stabs
• 5mm wallfoam core fuse and 2mm wallfoam side panels
• PiccoZ props
• 4mm 18 Ohm pagers
• 50mAh LiPo
• acryl paint
• Tissue with yellow color from inkjet
• 5.5 grams
• 6" wingspan

I tested it at dusk - because there was almost no wind - and it seems to fly. I can steer left and right and it keeps aloft at a bit more then 1/2 throttle. I have to steer it very gently though, as it can easily get into a spiral. However, I have the impression that it is rather stable in flight. Real tests will be conducted once the indoor season starts again in October ;-)

For trimming I put both motors at the same distance from the fuse. Both motors induce a drift to the right. So I let the prop at the right point down and the prop at the left point up. This will cause a upward thrust vector at the right side and a vertical downward thrust at the left side. This seems to be sufficient to compensate for the motor torque...

Some pictures below.

Johan

Nice work Johan! Only 2 more months till october! Can't wait!

Why did you choose the 18 ohm motors? Do they provide more thrust than the 10 ohm motors?

yrn1: Long time to wait ;-)

Village_idiot: That is what I had lying in my drawers... I would guess that the 'hotter' 10 Ohm wind would give more power...

Good, that is what I was hoping when I ordered them the other night.

BTW, I ordered some upgraded tail props for the ITC Micro Mosquito, they look very much like the PiccooZ props, but you can actually buy them as a part (not cheap though). Once they get in and I have a chance to try them, a review will show up in here https://www.rcgroups.com/forums/showthread.php?t=728851 or in a separate thread.

Dude, nice work! Try this one in that scale.
F-4, 10 in long, 7 in wing span. AUW 14.6 g. Differental thrust.
