I can't make the plane lighter. I need more power to pull this thing around the field. I even had an experienced pilot fly it twice and he agreed it is way under powered. any recommendations on a motor?
What is your AUW? Mine weighs in at 820g currently (due to additional glue after repairs and landing gear) but still flies fine with a 1550 mAh 30C bat, Emax 2220-07 outrunner and APC 11 x 3.8 SF prop. Had to put in the landing gear in a bid to stop the foam ripping with a imperfect landing.

I have commenced a new build, this time with 1.3# foam. Thinking of putting in additional reinforcement on the fuselage. I have ripped it in 2 places (at the wing root) as well as just aft of the nose doublers, the foam anti twist panels were not spared either. It happens when the tail tries to whip around after a hard landing. Anyone experienced this phenomenon ?

Lookin good guys. I've started gluing the horizontal pieces together. I'm still waiting on my harbor freight airbrush to put paint on before I glue verts to horizontals.

My airbrush arrived and my homemade cable to attach to my air compressor seems to work ok. I've got the compressor set to 30 psi. Time to practice with this new toy and get familiar with it, then on to the real paint job.

Slow buzz air brush opens up a whole new meaning to building!!! when I started to airbrush , it opened up another side to plane building than I ever thought. good luck! Don't be afraid to experiment. there are some great you tube instructions. dont be stuck on your 30#PSI remember to move the air pressure around. you will know when the PSI is right.

Thanks twister,
I've been reading the painting tips by adreher (sp?) posted in the scratchbuilt forum. The 30 was just a test of my air line I made. I've got a template of the main horizontal airframe cutout. Now I just need to settle on a scheme to put on it. Question for ya. Did you have the stiffeners glued on before painting or after? I notice I can see the step on the leading edge of the wing and your wedge angles over it. I was thinking of putting Yak 55 in large lettering on the wing, but was not sure how to really go about it with the step. I may just keep it below that raised area to keep it simple for my first airbrush job.

Keep it below. it is a pain to spray over the step. I use that blue painters tape. It works well, sticks good to the foam and removes easier. I printed out yak "55" on my smaller version. then I cut out the letters and had a template. worked great. I also use contact paper/ sticky shelf liner. for templates

Twister,
Good lookin plane. I'll definately go with lettering below the step, so I can use a template.

I removed the motor from the mount, I was right, it was rubbing. I pulled out the dremel and ground more of the mount. hopefully it will rip out of my hand. I hope this solves the problem of lack of power. I hope the weather is ok tomorrow to give her a throw. I will keep you posted
