I'm OK with the looks of this one. The first attempt reminded me of those 1800s illustrations of what a steam engine powered flying machine will look like someday.
It ended up wider than I would...

I have flown the new 70 incher at the new club field but the main hwy to the west is so close to where the pilots are supposed to stand that I feel too boxed in right now. The club frowns on speed...

I was close to trying the plane today but noticed it didn't have the same amount of elevon travel in the UP mode. The elevons themselves dont have any binds but to check the weak servo meant knifing...

If you build a delta or flying wing with a light enough wing loading and with a well set CG I've never needed any noticeable "reflex". It's easy enough to prove after you get your Diamond Dust or...

Here is the check of the engine alignment and it looks close enough to me. I moved the CG back and increased the elevon travel. I think this is the 3rd swept wing pusher I've built with .049 power....

I think so..more like definitely do not want any DOWN thrust.
I'll take the time to check the thrust closely this time.

I'll bet they have a quick and easy way to build them.

My first toss of the Boomerang did not go well. It went straight in as if it were very nose heavy and if the elevons were reversed. I think...

I use the fuzzy CA hinges .one drop of thin [fresh] CA per each side of the hinge after the gap is exactly where you want it. Just be very careful about slitting the 1/8" balsa. Keep telling yourself...

The HS 55 has the tiniest gear teeth made out of plastic. I guess that all other 9 gram sized servos that look just like HS 55s are built similar. If you have too much vibration feeding back through...
