This is what the manual shows. I suspect mine is slightly tail heavy with a 1300mAh 3s 20C Loong Max in the front compartment, and the ESC in the rear compartment.

I guess if you're nervous about it, add some nose weight to get it to the 1/2" forward of the bolt position, then reduce it after you've flown it a bit. Do change the prop before you fly though. It's a struggle to fly with the stock prop. I find a 10x7 much better. Others prefer a 10x8 but I haven't tried that. A 10x7 will give a longer flight time than a 10x8, but a bit less performance.

Just saw this on my YouTube feed. I am very intrigued too bad the supplier is BH. I still might have to get one if it is really 3D capable.

That is just like a scaled up version of the sttip !!!! Gotta love it !
I have no space for it, but I'm guessing this will be sold for years and years, and YES sooner or later this will be in my hangar !!!

Judging from the video, there doesn't seem to be any doubt about IT'S capabilities! Man! - that thing is HUGE! And just like the sttiP, it floats when power is down.

Yeah.... this could be fun. Hopefully by the time they get it, BH will have had an epiphany and discovered how REAL customer service enhances their standing with the R/C world.

I wonder what size lipo a thing like that needs, and how much it would cost to buy half a dozen, which is my usual number to take flying. It's just curiosity though. I've got nowhere to keep something that size.

If you are just looking to seal the decals Pledge pure acrylic floor shine works great. It is water based. Apply with a foam brush. To remove you can use a solution of ammonia. Train guys have been using it for years. I use it to put a gloss on flat or dull paint jobs.

Cool. I'll look out for that. I think we still get Pledge products in the UK. I'm not very domesticated so I don't normally buy that sort of thing, but I'll look next time I go shopping.

It's a model 12 Pitts, totally redesigned from the old S2 we call the sttiP with new wings, tail feathers, and an M14P radial putting out between 360-450HP.
"The Beast" is a popular M12 Pitts...
Runs on 3300 6S lipos, looks like it's a foamie, and best of all it's a 63" wingspan qualifying it as a giant scale biplane

Thanks for the info! I do not mean to say the plane is not 3D capable but BH does like to say one thing and the plane really does not stand up to it. Pete is an excellent pilot and makes almost all of their planes look amazing but in reality they are not. That is why I said what I said. Until a member of the public gets a hold of one and tells us different I am going to be skeptical (even though I just want to buy it right now!!!).

Someone already started a thread on this new Bipe and yes Pete has responded! Here is a link to the new thread if anyone is interested.

Andy...

The aircraft in this picture is the ART-TECH Pitts. It very close to the HK Pitts Special (Blue and White checkered pattern on the under wings). Is the CG at the same position for both models. There are subtle differences between them that might change the CG.

I have a new 10x8 SF paddle prop that I plan to use.

Saiddad.....

The Art Tech Pitts and the HK AT Pitts are the exact same plane. Other than the decals, there are zero differences - zero. Note that HK identifies it as the AT Pitts, and that is because it IS the Art Tech.

ANY information or detail derived from the Art Tech manual is directly applicable to the HK. Including CG location.

Sometimes I seem to get a bit of torque roll if I'm too clumsy with the throttle...
