Dear Paul,

My name is Gerhard Schiffmann, and I've recently completed building a brand
new experimental airplane of my own design (see attached photo).
It is a fiberglass amphibious plane, based off of the Dyke Delta planform,
with the exception that it is a pusher configuration. The powerplant I
selected for my plane is an RX7-20B, non-turbocharged, rotary. Currently,
I'm in the Phase I testing of the aircraft and have successful completed
several high-speed taxi runs, including a sustained lift-off of a few feet
(for about the distance of the Wright Brothers first flight haha).

I've currently been struggling to program and master the accompanying engine
control module supplied by Traci Crook at Real World Solutions.
In this endeavor, I've been trying to contact Traci, but have been unable to
do so. Therefore, I was hoping to reach out to other Rotary engine users, in
attempt to receive some assistance, insight, and/or tips on programming
these amazing, yet misunderstood, engines.
Obviously, I have the engine up and running, but it's just the final tuning
of the engine for various throttle positions that I need some assistance
with.

Any help or recommendations that you would be gracious enough to provide,
would greatly appreciated.

Sincerely,
Gary  Schiffmann

Gerhard/Gary-
Wow, that is quite an interesting design. A bit like a small version of the
Russian Be-103 amphib, I always thought all we need to do is make a carbon
fiber bottomed version of it scaled down with a couple REBTT rotary
engines.....would be lighter and the cat's meow! I even rode in one of them.
Built like a tank.

Keep us posted on your progress. I have a Traci 20B unit, do you have the
instructions that came with it? I can dig them out if you don't have them.
Maybe some of the BE-103 design features might help out your water
maneuvering.
Send me/post your email and I can scan them for you.
