RE: FUNJET

Good stuff Gryphon:

Here is the bird at hit 135mph in a 20 degree dive. I have had it for a year and a half and only recently crashed it into the door of a car (no damage to the car) but plane...

RE: FUNJET

Great vid and story about the smoke trail! I once smoked a lipo in a 5S crash. Lots of smoke in the snow. Guess you don't have to worry about ice and snow out at Pearl Harbor. . .

I set-up a...

Nice video. Super high quality stuff. You are brave to fly all that kit over the water like that but it makes for great images.

I used to fly with video goggles. I used an Easystar as the...

There is a guy on another forum who lost his entire Funjet due to a bad AR6100. I encouraged him to phone Horizon and he did. They admitted that they had bad "firmware" on the pre-1.2 version of...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

Good point about powering the receiver. I am pretty sure that my in air shut downs (reboots) were due to voltage ripple. It happened when I was running a high amp set-up, which Medusa's site says...

Gryphon or anybody else with Motocalc:

Can you run the following motor through with different apc(e) props on 4S 2200 mah 25C-30C to see how it could be propped for about 900 watts?

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

That flying wing is cool.

I think part of the reason I may have lost the link with the AR6000 is I did not have the ants at a 90 degree angle. They were at 180 degrees from each other - could...

How far was the plane from you? I lost control last week-end at about 1000 feet away over some trees at maybe only 100 feet up. I thought it was a bad battery connection but perhaps it was the...

Any users of the FMA Co-Pilot out there? If so, what do you think of it? Will it work over a snow covered field?

I just ordered one of these babies and can not wait to get it. Hoping it...

Thanks for the wind turbine link. Seems interesting. I will check it out.

Well, I don't know about 120 mph on a Stryker with that set-up. I think you might need another couple of hunrdred...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

About the 16/25/2, I can only recommend it if you are willing to run a high amp set-up. You will need good batts. and at least a 70 amp esc for 4S flight in order to run a decent sized prop. I...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

If you want a motor that is similar but will last way longer and can be pushed to death, then Mega 16/15/4 is the ticket. 29 amps on 3S with 6x5.5 apc(e). Your stock 25 amp e-flight will be fine. ...

I was unable to find any reference to the burst rating of the ESC. It is the Jeti 70 amp Opto from Hobby Lobby. Had I to do it over again, I would have gone for the CC 85 HV so I...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

Thanks for the encouragement but remember that my testbed is the Funjet, which is slightly smaller, lighter and more aerodynamic than the Stryker.

When I say 1200-1300 watts to get to 150mph,...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

I will get a tach to see.

Based on power equation, I need 1200-1300 watts to get to 150 mph. There is no way I can get to 1200 watts with my 4S because even if the batt. could handle it, the...

The 921 watts in-flight versus the 800 watts in my house had me scratching my head. Why is this set-up drawing another 121 watts on the exaxt same system in flight? Then it...

Aero:

S is the number of cells. 2S, 3S, 4S, etc. C rating is the output rating in amps. 20C means that batt can put out 20 times the size in mah. So, 2200 mah is 2.2 amps. Thus, 20 times...

RE: F27 STRYKER -Way Past the Limits Part 6 -Go deeper in to the Dark Side...

The real satisfying part is that the power/speed equation for a given airframe almost perfectly predicts the extra power needed to move from 109 to 135 mph.

The 109 mph bird was powered by...

Here is the flight from this morning with 16/25/2 on 4S 2200mah 25c-30c with Graupner 5.5x5.5 prop. Top end was 135 mph. This motor combo is now the fastest I have flown this plane. You guys were...
