Getting everything right before first flight.
The wings were not going in all the way.

I wet sanded the spar with 1500 grit paper.
Cleaned up the front and rear holes in the fuselage where the dowel pins from the wings slide in.
Removed the multiplex connectors from the fuselage as they were pushing in when I put the wings in.
Here is what I found, one multiplex will not connect.

Plan to maiden the Viking 2E this weekend.

It has a Neu 1509/1Y/6.7 with 5S 2200 battery 3+2, RFM 17 x 13 prop.
I have a spare fuselage also, may put in my 1110/1Y/6.7 for a lightweight setup, but let me get this thing in the air first.

I have been flying the Backfire on the 17 x 18 with a 5S battery and it just didn't feel as fast or as much power as ecalc says. Pulled the data log and it isn't. Under 2000 watts. I think my offset twisted spinner isn't twisted.

After stepping on the back of the fuselage I did a repair with some directional carbon. To balance the CG I removed the 1509/1Y motor and put in a 1512/1.5S/6.7
In this video a TP 3850 5S and RFM 17 x 18 prop.

I want to try a 6S soon

Been flying the Mini Corado a while now.
Video was shot with an RFM 15 x 15 wide prop on 4S, about 1550 watts.
I plan to put that prop on a 5 degree twisted spinner.
Mini Corado Hotliner (1 min 3 sec)


Today I flew it with a 16 x 17 prop, over 2000 watts and it showed. Prop speed about 144 but the acceleration was much better, faster than the video above.

Felt like I am close to the limit now, prop clears wing by about 1/8", motor and battery are pretty warm after flight. I just did short bursts today, first time with this setup and it was close to 100 degrees.

I think with longer motor bursts I can get another 500 rpm of prop speed.

Everybody at the field comments on it now. When the launch is just a 3 second burst it is running hard.

I put in a Neu 1110/1Y/6.7 motor in place of the 1105.
A few flights to dial it in then put on a 15 x 16 prop on a 4S it was really fast and roasted the ESC in one flight.

So, I put in a spare Ice Lite 100, 3S, 2600, 55C battery and a 16 x 17 prop.
Just barely clears the wing. Flies really nice, 1150 watts on launch, about 1100 on each motor burst afterwards. Prop speed is about 115 mph.

This is a nice combo, not insane fast but quick enough to be fun. I put a eneloop AAA battery pack behind the wing when I put in this motor. Thought it would be nose heavy but it isn't at all, will need to move the battery pack forward.

What is wrong with Gensaceusa.com

I have bought many Gens Ace batteries. Most have performed well. I have one 3S I bought recently that was DOA, only registers 2 cells. I have submitted multiple tickets to return for exchange or credit.

They have a separate site for customer support, can't get through on the phone.
http://help.rcdiscuss.com

I can log in and see my ticket but can't respond or update to anything they say. I have told them but no response.
The service sucks.

I have about a dozen flight now on my mini corado.
Neu 1105/2.5Y.4.4 with 2200 3S battery.

I started wtih a HobbyKing carbon 13 x 8 prop, great for the first few flights.

Took a RFM 14.5" x 14 and cut it down to 12.8" x 14, 67 amps on the bench. Flew a few times on a small field by work, flew great. Then flew at a larger field on the motor a lot, 15 seconds at a time, nearly burned up the motor. Didn't have my IR gun, data log was unable to parse data. Went down to a 13 x 11 for now.

I have two Sky Lipo 1300 4S batteries coming to run 2600 4S, possibly a 10 x 8 prop. Don't know if I am going the right way or not, just seems the little 1105 with the 4.4 needs to run rpm, trying to make it turn a 13" prop makes lots of heat. Maybe wtih the 10" I can do long motor runs.

Two flybys with some speed, last one slowing it down a bit.

Thank you Miklos and The Tick for all of your help today.

Did the Maiden Flight of the Mini Corado today.
I was really pleased with the way it flew. Launched very well, very little trim needed.

Current setup is about 500-600 watts, weight 30.5 ounces.

The Mini Corado is very docile and easy to fly. At this weight it also can thermal and land at very slow speeds.

I have seen others here with this model with much higher power setups. I can see wanting more power but I wanted something I can fly in a small area and thermal with a broad speed envelope.

This video is a bit rough. I will try to post some better footage.

Almost ready for the maiden flight. This is the carbon version. I tried to make it light, Neu 1105/2.5Y/4.4, 1800 3S battery, 13 x 8 prop, DS09 and D47 servos.
