i agree BRI the shubies use a much bigger tail pipe ,closer to 4 " i had to cut the end of the Nacelle off to get the size needed .i put a ply wood ring at the aft of the nacelle and that helps keep the shap back there.Rodrigo very nice looking Falcon ,what mods if any did you do to the airframe?

New retracts for the Falcon120

Hi guys........Just wanted to post a pic of the new electric retracts I just finished the prototype of the mains. Nose gear to follow shortly. They will work on 2 to 3 cell LioPo's and have a gear door servo sequencer that's programable built in. This version has brakes installed for the turbine version of the Falcon. As soon as I get them installed I'll make a video showing there operation. As for cost the starting price is $125 per retract, or $200 with brakes, wheels, and tires. One of the nice features about the retracts, if they are up, you don't need to turn on the receiver or transmitter. Just turn on the power to the retracts, and they come down. I will be providing a switch that provides power to the retracts and the receiver, and a BEC as an option.

Go ahead and test it yourself, if your batteries are large enough and of good quality it will pull a lot of amps on high cellcounts, trust me on this. Take a look at the info on the XPS site and see how much the difference is in the ampdraw between different battery setups on 15S, they have numbers for 3 different setups listed.

A decent clamp on meter is like 25-30$ and is something any serious electric flyer should have in his toolbox anyways so get one, you will not regret it.

Amp Meters

Well I am an electrical contractor and my regret is that my clamp ons are only for AC. Lots more than the 20 or 30 bucks for them.

I have a 3000 X 3 battery - 9000 mAh so it should handle the current, but I was hoping the specifications were fairly accurate. My speed controller is only good for 200 amps so ill invest in the meter.

When I bought the fan I was thinking I was going to get the 24S 250 Amp but have the 16/200 so I am right at the limits and now think I may need to drop down the load again.

I bought this as the 20KW advertised setup and XPS seems to have lost interest in this and I cant get my plans close at this point.

I am hoping Fightercat gets back in the game - but they have also backed away.

I have had this project on the back burner for awhile but guess I need to set up a test stand to see what I actually have here.

???????

Looks great Rodger! I plan to run it against the Schubi in the Velox and compare the results.

Billy, Stu mentioned you shamed the BVM crowd with your Stumax powered jet, is there a story there?

Incredible!! What motor did you use? I'm getting 164mph on my Carf Spark with the 110 on 10S using a Neu 1912-1Y (175mph on 11S) and I would love to upgrade to a 200mph bird.
