Hello Ron,

Well what about the weight I can tell I measured it a while ago without the smoke system builded in, it was within the maximum weight defined on the specs. I don't remember the count but it was in any way acceptable. The smoke system adds some 300 gram on the CG. But that's should not be noticed in flight.

Anyway about last Saturday. I was scared ****-less because I started building the plane about 5 months ago, relaxed in evening times. Spend some money here and there. At the end spended a lot of money on the plane. I practiced and practiced on Real-Flight G2 for about 3 months on a row, trying to land and fly 4 point rolls, knife edges and all other stuff. I practiced a lot at stall speed landings and found out it steers best at stall speed with rudder.
I've read alot about landing start taking off bi-planes and I can tell you I, last Saturday was scary. BUT I was a pro landing the plane in the simulator, so why not in real.
Last weekend was special, because it was to be the first time I give an new airplane airborne for the first time. Normally I give the transmitter to a known-to-be-good pilot and give him a try. I decided this time to do it on my own. I rather give myself the blame than somebody else.
This is my second big scale plane, the other is a midwest extra300s so I'm aware of flying the big ones and know there differences compared to there smaller counterparts.

At the field 15 people stared at me while building the eagle up and asked some advise from a guy (Rene Boerlage) about landings. He said: Just keep the speed up when you land, that's it.
Okay engine running, doing some final test and up to the strip. Added some power and a very little bit of rudder than, oops she's airborne already at half gas. Wow so easy! Giving here some altitude and noticed to much up so I trimmed here down. Leveled out an flew some ovals. Pointed here nose into the wind at high altitude and tried to lower the airspeed. Well I could not let here stall because the speed was that absurd slow so made a mental note; that speed at 1/3 gas and still stable. I mean the speed was almost a guy could pick here running out of the sky, amazing slow.
Tried some loopings and rolls, absolutely cool!!
Then it was time to land, lower the altitude knowing to give the plane power at turning the plane into the wind at low speed, about 1/2 gas. Coming in, playing with the gas and just when you think you can pull back the power, just wait 2 seconds longer, you'll see it yourself. If you pull back to soon, you'll run out of elevator and may stall it or fall out of the sky. That doesn't matter when you approach at low altitude and stay there, it will land just sooner.
Slowly applied some elevator and a little more while pulling back the gas and there she was.

Conclusion:
--------------
A very easy flying airplane to me. It slows down very, very quickly but it's not a monster to land, just remember to fly it to the ground.
I've not well tested the zenoah G45 on this plane, I've noticed a 20x10 will probably do much better than currently turning a 20x8. It was pulling the plane across the sky very strong.

I'll post some pictures of the engine combined with a bison smoke muffler I bought in America and shipped with FedEx to Holland.
