RE: Extreme Flight Vanquish 2m Build Thread
[quote]ORIGINAL: Si-F3a Just curious if anyone else has had this issue with the Vanquish. Am asking as I have just spent a couple of hours on the same issue? I have an earlier vanquish and had no problems at all. The set screws on that (with loc tite) move easier that those in the 2 stabs I have been working on tonight. Result is I have 1 stab with screws in that wont move any more and the other one has both sides Naged up so bad I cannot get the dammed things in. have already sent a mail into EF and am awaiting their reply, Simon [/quote] My screws were so tight I used a bolt to clear the thread. It was like there was a layer of glue in the threads. I had to resort to using a bolt with an angle cut to clear it before using the set screws.

Is anyone using the brake setting in the ESC of the castle HV80? Does the plane require the brake setting for the down lines?

[quote]ORIGINAL: jonlowe Stock hardware is fine. The only thing I replaced were the wheel axles, which I substituted with Central Hobbies aluminum axles for weight. If you want to use pin hinges, the ones supplied are not good. Replace them with genuine Robarts, or cut slots for CA hinges, which is what I did on my second Vanquish. The first shipment of Vanquishes used CA hinges. The stock pin hinges are soft, and will develop slop over time. [/quote] My Vanquish has the stock pin hinge. I was thinking of replacing it with SIG easy hinges. But I will have a look for some of the Robarts.

RE: Castle ESC screaching during brake-to-throttle transition
[quote]ORIGINAL: DaveL322 Brake strength is how much the ESC is shorting the motor. To compare to the brake in a car, it is how far you are pushing the brake pedal. Foot off the gas and coasting is 0% brake, and 50% is halfway to the floor, and 100% is mashing the floorboard. If you complete inflight logging with an Eagletree, you will see reverse current flow going back into the battery when the brake is engaged. On 10S pattern setups, I've seen spikes of 10 amps when the brake is engaged, but generally peaks are around 6-8 amps, with nothing more than 3-4 sustained (with Castle ESCs). The way the Castle ESC is setup (and I believe most other brands are similar), the brake % is relative to full amount of braking available, which varies depending on the prop RPM when the brake is engaged. Engaging the brake at the start of a downline may generate 4-5 amps of reverse current....while engaging the brake at the end of a long downline (after the plane has accelerated some amount) will generate more than 4-5 amps. Engaging the brake on landing approach is only going to generate 1-2 amps. In general, the higher the brake strength, the slower the downline. How effective the brake is depends a lot on prop selection and airframe - ie, a very draggy airframe with a relatively small diameter high pitch prop is not going to benefit much from a brake as most of the drag is from the airframe itself. Keep in mind the brake is not a governor, but a preset amount of ''drag'' the ESC puts on the motor to limit the amount of RPM increase in a downline. It is not uncommon for pattern setups to reach 4000 - 5000 RPM in a downline without the brake engaged. [/quote] Would you be able to post an image of a graph with the negative spikes?

[quote]ORIGINAL: hezik Besides wanting to fly on 10s, I don't see any reason why not to use the Hacker A50-16L. The Scorpion is obviously an engine with quality issues, i have seen one spit out it's magnets in real life, and in this thread there are like 3 users that had rings or magnets come out. I fail to see why people insist on wanting this engine, basically it's a crap engine, to put it harshly. The A50-16L is not perfect either, but at least it doesn't fall apart. Most other alternatives don't fit, or you need to do some work on the nose. If you don't like the Hacker A50, then go for the inrunner Hacker. [/quote] I have been using the A50-16L with a cut down 19x12W APC on 8s for 180 flights without a problem so far. That includes one contest where the wind was between 50-70km/hr, I was very glad I was using a 12in pitch prop that day. However I only use the plane for pattern practice and comps.

RE: CC Phoenix 85HV brake settings for AXI 5325 or 5330?
[quote]ORIGINAL: F3A Unlimited This is probably the most difficult scenario for a controller to handle without losing sync with the motor. The more braking you have, the harder it is to do. My understanding is that the braking holds current across the motor to try and keep it from freewheeling so more braking = more current across the motor to try and hold it. Then you advance the throttle quickly and it must instantly transition from holding the motor to a rush of fwd current while maintaining it's sync with the motor. Usually a slower transition or a weaker brake setting will fix the problem. I have seen it happen with controllers more than 2X the price of the Castle so I don't see it as a defect although a tweaked firmware may help by giving you a slow transition no matter how quickly you advance the throttle stick. [/quote] I had a similar problem with a hacker and a HV 80. I now have a brake setting about 90%, but i still get the sound one every 30 flights. Try increasing the brake.

[quote]ORIGINAL: hezik If you're flying at P11/F11 level, it does indeed need a brake. Also you might try to find a suitable wideblade prop for your engine, or a threeblade prop. [/quote] I have to agree totally. I flew it three times without a brake and thought I had a problem with my brake setting. Without the brake on it is like a rocket in downlines. The best setup i have found was suggested by hezik. Cut down an APC 19x12 wide blade electric to under 17' and have the brake set in the ESC. I have my CC brake set to 90% and .4 sec delay.

RE: Sebart Wind 110
[quote]ORIGINAL: hezik Glowpower simply won't fit, the nose is to small to fit a normal glowpower engine in. RCV makes engines that might fit, but please, why would you.. spare yourself the time, pour a few litres of oil over the airframe and break it in several places, then you'll have the same effect, without all the hassle. You don't need 4 sets of batteries, or 2 charges.. that's nonsense thought up by glowpower-fans. I only have one charger and 2 packs, and have made about 900 flights in 1 year. If i go to the field at, say, 12:00 and fly up until 18:00 then I can fly about 12 flights. That's more than you should want to, if you're really into F3A flying, 3 or 4 wel concentrated flights is about the max. It's something all the glow-power people say, 'you need a lot of packs and 2 chargers and can't fly as much'.. in realyity, with only 2 packs and 1 charger, I have flown more than any glowpowered-flyer at our club. Besides that, think of the costs. I switched from glow about 1.5 year ago, and cost-wise I'm now flying for free, for just the cost of the fuel I would have had to spend to fly as much as I did, I can buy the complete airplane, including everyting, charger, 2 packs, and transmitter.. and then there's still money to spare. Again, this just for what the fuel would have cost. This might be different in other locations, but we pay something like 25 euro for a gallon of fuel (=roughly 31 dollar). About the Scorpion engines.. there are now 2 people in this thread that have had the same defect, and recently another scorpion engine (other type) at our field had exactly the same problem. I would say it's not an incidental problem. [/quote] Are you charging at 2C? Do you take a big car batter as the source?

RE: Castle Creations HV80 ESC
[quote]ORIGINAL: F3A Unlimited Use either ''outrunner'' pwm or the lowest fixed value and ''low'' timing for big outrunners. The logging can be turned off too but I have only seen that give a slight knocking sound at full power instead of a loss of sync during acceleration but I can't hurt to turn it off and try. Also make sure you are using good connectors between the motor and esc. The esc needs to clearly ''see'' the motor and bad connections can lead to loss of sync. Some of the real cheapie bullets are more like ''gold tone'' than ''gold plated''. [/quote] I tried it in outrunner mode and it was worse. I was using medium timing but i will try low timing and 8KHz PWM. I am using 4mm bullet connectors between the ESC and motor.
