RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Thanks man.

Love the smoke on the video. I think I've pretty much talked myself into adding a smoke system. Based on reading up on the RCG engine you mentioned using, I think I'm only about...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

I must be balancing my plane wrong, I can't figure out how people are flying these happily at 5.5 inches back. I like 'ECM tail heavy and this was simply no good at that cg.

Thanks guys.

Interesting that you changed wing incidence popphil, one of my initial thoughts during the first flight when the plane kept ballooning was whether the wing incidence was too...

BTW, as balanced, I'm at 11lbs 2oz rtf. With the Saito 180 up front on 30% heli fuel, it *should* have unlimited vertical.

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Still afraid to fly mine as balanced, it's slightly tail heavy at 135mm back from center of top wing. I still have room to move the Throttle servo and battery up front (4-5oz) but I'm holding off...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Plane is programmed and nearly ready for maiden.

I'm significantly concerned about the CG on this plate, measuring 135mm back from LE of the top wing (even though the instructions say 110),...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Finally got to make a few updates, (wow twins are a lot of work!). I got the aileron servos and pushrods done and got most of the radio equipment in. I did a weight check and I'm at 11lbs 2oz. The...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Given the plane is probably 75% done and is mostly assembled, I decided to do a weight check. Currently we are at 10 lbs 12 oz on a postal scale.

I still need to add:
Aileron servos and...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

More progress over the weekend and some notes and tips:

I didn't about the full size pushrod so thanks for getting me educated Mav.

I've no clue why the bipes in general aren't more popular, maybe people think they are too complex? I definitely have...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Yes, as configured, the kit actually is built to use two servos for the elevator. If you look at the radio mounting tray, there is a rectangle cutout that will fit 3 servos side by side. The middle...

RE: Nitroplanes Pitts Special 120 aka Pitts M-12-120

Lower wing measures 57.5" (give or take an 8th), upper wing measure over 60" edge to edge. This should qualify as you can add a dashboard and pilot pretty easily as well.

That said, as it's...

Yes and actually that whole area is open when the canopy setup is removed (which is held in by pegs and two screws into blind nuts).
