Rigger engine break in during the last of the 3rd 2oz tank I brought up the rpm some
to see what it would do on the pipe NV was rich but lean enough to get 44,412 rpm!
Should do about 46k+ once closer to the sweet spot will post a running vid soon.
Maiden run will be rich by about 5 clicks off peak.

Outrigger - Picco .85cc /.0519ci / Profi Tuned Pipe 44,412 rpm
Original designed outrigger hydro for Picco P-Zero
On the end of the 3rd tank I was able to lean it out enough
to get a idea of the top end still rich but on the pipe
should do about 46k no load once the needle is set.
30% nitro 18% castor Will post a maiden launch vid
perhaps next weekend.

Here is the running vid of the maiden voyage I had too much prop on
the tail so the engine lost more rpm than I had wished, goal is 37k passes
current best pass 28k. All the same fun 1/2A project and the first posted
vid of a outrigger hydro running on a 1/2A engine in North America. Pumpkin
