Just taken delivery of an Anthem. I opened the box hoping there would be no damage and I was delighted to find that everything was in perfect condition. Nice sturdy box and the fuselage is well retained using the wing tube hole to firmly fix the fuselage into the box. A wood cross member also helps to prevent the box being squeezed in. The other parts were all nicely packed in bubble wrap and securely taped into the box. Full marks to BJ Craft's box design.
Weights (in grams) for the bare components are:
Weights (in grams) for the bare components are:
Port Wing ............... 316
Stbd Wing ................ 315
Port TP and elevator 88
Stbd TP and elevator 88
Canalyser .............. 102
Fuselage ............... 1044
Rudder ................. 60
Canopy ................ 82
Wing joiner ................65
TP joiner rods ......... 10
I've not included the undercarriage, spats, wheels and other hardware as I might use other stuff. I was very impressed with the wings being within 1 g of each other and the TPs being the same. weight. Well done BJ.

My Feedback: (4)
Able to get 2 six minute flights on my Anthem today. CG somewhere between 280 and 320. Almost no trim changes needed. Slight pull to canopy both in left and right knife edge.
Adverrun contra with Kontronik XL20-55, both props are 22/22. TP 6000 10S. Battery not even warm. Motor very hot - have to think about this…

I took the precaution of checking bolt length
I used the silver bolt to check length and it wasn't quite long enough while the black bolt (supplied) contacted the fuselage as you said. So, I cut 5 mm off both supplied long bolts and all was fine. Thanks for the warning.
What delighted me was that the U/C legs came predrilled and the way they were shaped provided you aligned the front edge to the u/c box the wheels were aligned to run straight ahead. The other astonishing feature was that both predrilled holes in the u/c leg aligned with the slots in the u/c plate! The slots are across the fuselage but there is no real tolerance fore and aft. Well done BJ Craft on some accurate jigging.

BJM - at what stage are you measuring motor temperature? I had an onboard temp monitor on my motor. There was around a 7 deg C rise above ambient when in the air, but as soon as I touched down the temperature would start to rise and by the time I was back in the pits the temp rise above ambient was about 20-25 deg C. I did once take off with the motor temp at 20 deg C above ambient and as soon as I was airborne the temperature started to drop and stabilised at 7 Deg C above ambient.
So, what I learned was either take a temp reading as soon as you have landed or else fit an onboard temp sensor on the motor and monitor it in flight. Checking in the pits is a waste of time as heat soak and lack of cooling air push the temp up much higher than it would be when airborne.
