Ah, ok.. so do you use a smaller pinion when running 4s?

Actually more cells (and same mAh per cell) ‘should’ give longer duration. At least if all else remains the same. Assuming that the heli uses the same power to fly as an identical heli on 3s, then according to Ohm’s law increasing voltage means current (Amps) will reduce (Amps = watts/volts)...

The Trex 500 Pro looks great, just needs some red tail blades to complete the look:wink:. I used to have the same (though less red) but sold it to Neil (Holtneil) a while back. They are nice flying helis.

A while ago i picked up a second hand Chase 360. The original owner had built it but realised he's bitten off more than he could chew so sold it on before it even turned a blade. His loss was my gain because I picked it up at a great price:wink: I found a few issues with the build that didn't...

Nice flying site there Heliman!.. Nice trailer too, so is it towed by hand? The weather is stopping play here too, 50mph+ winds constantly for the last three days along with rain of biblical proportions. Lots of flooding and the fields that aren't under water are like bogs. It's set to continue...

Hi Heliman, It's Grunpy here, under new user name (long story) Good that you got it all sorted out. Have you also got the rescue and/or stability functions working using negative gyro gain? That can take some setting up in the Tx to get right. The bank switching option is also useful if you...

Neil, has your 630 got the newer main gear with the alloy centre body? Mine is the original all plastic gear which i think SAB have now gone away from due to it flexing under high load. Probably more an issue on the 700 and 770 than the 630 but still nice to have the latest stuff. I feel a...

3 blade heads are a little less efficient so you generally lose flight time with a three blade head. The extra call probably offsets that so you end up with the same flight time as the two blade on 3s. You should be able to reduce headspeed a bit compared to the two blade head which might...

Yeah, the geometry of the Align DFC heads doesn't suit many FBL controllers. It's often impossible to get the servo travel within it's optimal optimal range. KDE make longer pitch control arms for the bigger Align helis to address the problem. Here are the ones for the 550/600 DFC head, they...

Yeah, you are way over propped. According to the specs I've got for that motor on 3s the max prop size is 5x5.. I'd assume a 6x3 would be ok too but your 8x6 is far FAR too big.

Here's the link to the Extreme Flight page with their electric planes: Electric Airplanes I have the red white and blue Edge 540 and also the red Laser 200 Here's the Edge being put through it's paces (wish i could fly like this!)

Tony, The Trex 700 doesn't have any shims on the vertical or horizontal gears. You could of course add them if the mesh was unacceptably loose but by design it's not meant to have any and normally it's fine without them. The TT gears are pretty strong on the 700, it's the 600 that is usually the...

It's not intended as a tray radio, FrSky have another new model to cover that base (the X9E).. They havent released dimension as far as I know, but the story is that the case is quite closely modelled on the Jeti DS16. Possibly it appears larger than it is, it's hard to say without something in...

On the subject of the TT gears stripping.. Check the screws that hold the dual arm tail control yoke to the pitch slider. If these screws are a fraction too long then they nip the bush preventing it turning with the shaft. To test spin the tail by hand and make sure that the slider bush rotates...

Sorry, my misunderstanding of the request. I didn't realise it was just a loan being requested. I have one which I've no problem with loaning but two way international postage would probably come close to the cost of a new one, so not really cost effective.

It's not a cable you need as such, you need a Castle USB link dongle. Any regular micro USB cable plugs into the dongle. These USB Links retail for $20-$30 so unlikely that many folk would want to give a working one away. As already noted, if you buy a Castle ESC in the full retail package you...

For some reason you dont see a lot of onboard videaos from helis. I thought that maybe vibes would be a problem but it turns out video works pretty well, here's a couple of my efforts: Trex 600 tail boom mounted camera: Compass 7HV belly mounted camera: So has anyone else tried...

I didnt see another thread on this new Tx so thought it might be worth starting one. The X12S Horus is FRSky's new top of the range offering that looks like an awesome package. Apparently initial evaluation transmitters have just been released to dealers so full production should be running...

I've got the DC only version of the 300W Reaktor as a lightweight charger to take to the field, it's a great little unit. The AC/DC version is basically the same charger with an AC power supply built in. Personally I prefer a DC charger and separate power supply but i know many like the all in...

There are a lot of choices out there, the Turnigy Reaktors are hard to beat for bang for buck: At 300W this is about the most powerful AC/DC charger around: Turnigy Reaktor 300W 20A AC/DC Synchronous Balance Charger / Discharger (US Plug)
