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.

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.
