Herr 30" span Pitts Special Conversion

Hey guys,
I'm going to attempt to convert a 30" pitts special to electric. I have not started this project as yet. I know it has been done before. I can't seem to find a thread that deals with the conversion of this model from start to finish, so i will start my own.
Anyone who has ever built one of these is welcome to post pics or comments. Please do not put any info in this thread about the smaller rubber powered Herr Pitts.

my camera is a bit low on batteries right now, so I only have one pic of the kit contents as show below (I know I got impatient and started cutting one of the wheelpants free before I took the first pic)

If your pitts or the one you are interested in does not match these specs please post elsewhere. I'm really trying to help minimize the confusion that I noticed already exists about this plane.

**engine: .061 - .074
span: 30"
area: 300 sq"
wing load: 12.9oz/sq"
**weight: 27oz

** I mean to change these specs as we go along.

Hi Steve,
are u sure?
I mean I was all happy to find that someone had done all my work for me...but i went to the warren jones thread and was disappointed...

What I found was a scaled up version of the Micro Pitts by Chris3d, and the link to the page where he starts is here:

one difference is....this one is expected to weigh about 6-10 times what warren's micro pitts weighs

Trampling out the vintage
Here's a link to an electric conversion.

Model Airplane News did a review of the model build for glo a few months back.

Warren has two sizes of pitts in that thread. I believe his avatar has the herr pitts.

hey guys thanx for replying....
that link was just what I was looking did I ever miss it before?

I will try a few different power plants including brushed and brushless and perhaps try to determine the so called "hot ticket" either way.

I will also try to bring that 27oz weight down...I am sure it can be done.

Yeah I noticed he had a pic of a blue and white pitts that looks like a herr pitts, but its that kind of confusion that I'm trying to avoid, I'm really hoping this can be the definitive herr 30" pitts conversion thread.

A buddy of mine has done it with a miniac 1215/16 and a 6:1 gear box.
I think the lightest batteries he has tried was a 3s2p (11.1 V) 1200mah etecs (the pack is 2400mah)
It flies decently but I'm not too crazy about its performance.
I'm looking for an awesome display of power that will just blow people away.
(and I'm not trying to go broke doing it)

Sweet! I have the same kit and had planned to make the same type of thread. I have been distracted lately and have not begun building the Herr yet.

I planned on powering it with the Razor 2500 and the Thunder 3s1p 11.1v. I have all equipment for the build - just haven't found the time or motivation to get on it.

I will be watching your thread with great interest.

Herr Pitts

I built and converted this model as well.
The most fun I have had in a long time.
If you do a search "Herr Pitts" you will find a specific thread I authored on it in a casual sort of way.
Either way the model comes out a tad on the heavy side without compromising it`s structure. If powered right it`s a bullet and will do anything you ask it. At least mine did anyway.

Another Pic

She flew on;

Mega 22/20/3E
9x7 APC
8 Cell 1300`s or 1700`s

An aileron mod is mandatory on this bird. Like one on each wing in scale fashion.

One more

Here she is after several successful flights.

" Let there be no mistake, there are aeroplanes and then there are Pitt Specials, lets not confuse the two."

You will find out why when you fly one,.......if you live long enough.

all i can say is WOW!
the power from that 22/20/3 must be incredible....

I looked and found a thread by you called "my hot rod pitts"

cool if only i can build mine as nice as that...

I know that trying to lighten it up might affect the strength, but I'll still try to lighten it up a bit.....I'm also thinking of doing the aileron on top wing mod.

To guyaneze

I did lighten up mine as well, but it didn`t make alot of difference like I thought it would.

herr pitts plans 1 of 3

these next three pics should give you some idea of the work involved and show you the quality of plans in a herr kit.

herr pitts plans 2 of 3

this is the 2nd of three large plan sheets that come rolled up in the kit. The first was the fuse, this one is just the wings.
the top is flat and swept back, the bottom is straight but has some dihedral.
the plans only show ailerons in the bottom wing.
