Will do. We'll definitely get some good photos and videos using our friends great equipment. RudyD54 started texting me at 7 AM that MRC just made his "Holy Grail" a reality. No doubt one of the first to pull the trigger. That's why I "love" him, he's my "New Release Guinea Pig". With that said, he's always right on the mark! He's already talking about setting up variable thrust so I'm always learning something new from him as well.

The 2210kv setup was introduced in the F35 in 2019 and has become the power system for HP versions of all the single 70mm EDFs (minus the Yak130.)
The 2100kv counter-rotating setup was introduced last year when they started putting it in the Me262. This has become the standard, it seems, in their twin 70mm lineup and replaced the older 2150kv outrunner setup. The SU35, Me262, and the Airliner have all been upgraded to this setup, and the PJ50 and this B-2 were both released with it.

It seems twin 4000s (either in parallel or each to own edf) would fit this bird perfectly and not kill a single lipo. My SU30 is a lipo killer. I haven't configured the 2x lipo yet. Todays twin 70mm are too hard on single lipo. Of course, if you fly it like a B2, this shouldn't be an issue. I see this bird just cruising around in late afternoons... admiring the slow relaxing fly-bys. For me, a great way to end the flying day.

I don’t see folks hot rodding the B-2 like this. This potentially translates into nice long leisurely flights enjoying the visuals without stressing the LiPo.
Ordered one…sweet addition to the line-up. WTG Alpha, FW, MRC. Congrats!

I Fly at high altitudes with air density in the summer at times over 9000ft. Twin 70s with this wing loading should provide for some excellent scale flights with plenty reserve to get out of trouble.
I so tired of the attitude that some have over there.

Originally posted by xviper View PostLike EvanD said. No flaps. It should have read "flaperons/elevons". A flying wing with down flaps will dive, with UP flaps will climb. If you had the inner control surfaces go down as flaps do, the outer control surfaces would have to go UP to compensate. Then, you'd have the equivalent of "crow" or speed brakes. Most times you have a gyro, the TX is set to "normal" wing. The mixing for elevon takes place in the gyro. The neat thing about this gyro is that it incorporates a "steering" gyro, like what one would have when putting on an Assan steering gyro. Makes for very steady, straight line ground handling. A plane like this with such short wheelbase, tends to wander all over the runway. The steering gyro should eliminate that.

Originally posted by rifleman_btx View PostI bet it would be able to float around nicely power off too. I bet one could fly it like a powered glider and keep it in the air for a very good flight time, thermal hunting and all especially with the span.

Thanks, Gravy. After the PJ50, we thought the "no promo launch method" was ideal for the B2. Especially fitting, for a stealth aircraft. A bit of"Shock and Awe" to keep us all on our toes. One never truly knows what's coming next from Motion RC.
OPSEC matters!
This was April of last year shortly after the maiden flights on both jets.
