Outstanding segue....

Per my earlier post...new P-10 and 40A ESC.

It was about 10-15mph nearly 90-degree (variable) winds at the field this evening. Even the instructors were having to make 4-5 'go arounds' in 5 lbs. Avistars to get back on the ground. There were lots of gusts and weird 'convection lift' (thermals) going on around the grass/cement transition.

There were several slight skids and scuffed wingtips (these are very experienced pilots).

Could I have gotten my 2 lb. "foamy" up and down with my new P-10 and ESC 40A in those conditions? Absolutely! Many times I've done it, though, I had to deal with wing tip/prop 'scuffs' etc.

Stress reduction is the goal (for me).

My refurb'd crate is fresh out of "Bill's A&P shop."

I'll wait till Sat. AM to maiden it...thankyouverymuch! LOL!

Hehe I bet if you flipped the wings on a Radian, you would get a very interesting flight...

Run Time?

I'm using a MAS 10X7 prop. I tested it with the stock 9.5X7.5 prop and it still pulls between 32 and 35 amps at full speed. This is testing it for approximately 10 seconds at full speed to make sure I don't burn the motor out. Can anyone help me with this? I don't know what I would be doing wrong as I'm running 4XHS55 servo's and 2 of the original servos. Thanks.
Like Moosehunt2010, I am going to install a Power 10, 40 amp ESC and I happen to also be using the same Hyperion 2200 35C battery. I will also be adding the Custom R/C motor mount and Maxx Products 5 mm to 8 mm prop adaptor so I can use the stock prop (I have about 6 of them!).

I had to upgrade because after installing some robart strut covers tonight I took the cowl off to tighten the nose wheel gear screw and I saw some cracks in the stock motor. I was suprised because I have only had about 20 flights (no crashes) with only one slow minor nose over while taxiing.

Moosehunt2010, if your still here checking out this thread, or anyone else with the same set up....what run times are you getting with your set up when you use the stock prop? How are the verticals/performance with the stock prop?

Thanks,
Steve

Has anyone ever tried some belly/wing skids to fly off grass? I often fly from a place where the grass is longer then the wheels and the underground is a bit rough with that.
I will either see if i can get my hands on tundra wheels, but as that is not so nice for the scale look i rather go gear less. But without anything i am aftraid that the the prop and engine would get destroyed in no time.

The P10 gives a good mix of power and flying time. You should get ~7 mins in mixed throttle flight from a good 2200.

For an identical T:W ratio (exactly 1.42 for both), ~10 min flying times, and much better flying characteristics the Super Tigre .10 is a less expensive choice at $20 total outlay (can use stock ESC and battery) vs $160 = $60 (engine) + $50 (ESC) + $50 (new battery). The downside is that you have to drill 4 holes and buy a $ or two in hardware to mount the ST motor.

My comparo tests them with a constant battery, which is one way to compare but it doesn't let higher engine efficiency increase overall aircraft performance.

HI Coenraad, just tape the bottom of the plane and the leading edges of the wings, it belly lands great. You will need more props than usual, but if you cut the throttle, it should be ok.

Cheers,

Haha, I have unsubscribed. Nobody seemed to see the humor in my
"what the wings are inverted? Howcome nobody mentioned this yet?" post on the 100th page of just such ranting...

Just glad I didn't buy it lol. The Radian is just freaking sweet though. NO complaints there, but wouldn't want to flip those wings.

Yeah, how can you screw up a powered Glider wings?

Well, both models share a carbon Tube but, the Radian does not have any PAINT on the wings. Too bad about the EXTRA 300 what a freaking mess!!!

I use the same setup myself but with an APC 10x7 E, similar Lipo. I set my TX Timer to 8 Minutes, (I usually do mixed throttle flights) and I land after the beeps and put <1800 mah back in to the pack during charging. The stock prop draws less power, so if you start from 8 minutes you should not over draw your packs. Expiriment with how much you put back in the packs from there and you can adjust your timer accordingly, your flying style will effect how much you draw from the lipo on the average flight.
