RE: Parkzone NEW BRUSHLESS (YES!!!) P-51 Mustang RTF and BNF
As long as the servos still function properly (i.e. no stripped gears), just center the trim on your radio, and then center the ailerons by adjusting the control arm position and linkage length.

RE: 3S or 4S on a Twin??
I guess if you want to fly larger props, go with the 3S. If you want to maximize power and fly smaller props, go with a 4S. Below is an example of a 3S and a 4S setup from the Power 32 manual. The 3S setup in a twin will give you 960 Watts total, while the 4S setup (in a twin) will give you 1584 Watts total.

RE: Tips - Hat, Sunglasses and Whatelse?
I've never found gloves that are thin enough to use for RC flying, yet thick enough to provide any warmth. I use fingerless gloves or "cutoff" gloves in the wintertime. They keep the main part of my hands warm, and I just fly until my fingertips start to get numb! I'll wear some warm wool or mechanics gloves when I'm not flying & to prep the plane, then switch to the fingerless gloves to fly. I made a transmitter "mitt" that covers my hands and the transmitter, but never did use it much. It needed to be a bit little larger than I originally made it, and it was a pain to get on and off the transmitter. There are a few people that make these TX mitts and sell them on the internet, if you want to give one a try.

RE: motor wants to start backwards
Sensorless brushless ESCs may wiggle the prop a little at startup to figure out the position of the rotor. As long as it finally spins in the correct direction after that, you should be fine. If you are having problems other than this initial wiggle, then you probably have a motor or ESC problem. If your motor or ESC has been running hot, you may have damaged the motor windings or the ESC electronics.

If you are stressing your batteries with an 11x6, a 12x6 will be worse, more loading and more current. If you're going that fast, hopefully you have an APC speed prop. They are more efficient than the slow-fly or the MAS props.

RE: places to fly
To fly at any of those clubs, you'll have to join the AMA. I doubt any of the clubs have free memberships either. Intro Pilots - Each AMA charter club can designate certain members as "Intro Pilots", at a cost of $5 per year per Intro Pilot. Members designated as Intro Pilots can train newbies under the AMA's Intro Pilot Program. That program allows newbies to learn to fly with an Intro Pilot for up to 90 days before they are required to join the AMA. During this period, the Intro Pilot must log all sessions, and they are covered under the AMA liability insurance.

RE: Hot battery/esc
A Wattmeter is one of the best investments you can make if you are getting into electric flight. It lets you change your setup and verify that you aren't going to fry any of your components. They cost about $50, but if it saves you from frying one motor/ESC/battery setup, it will have probably paid for itself!

Sorry to hear about your accident. Glad to see you're healing up well so far! I've seen & heard of enough accidents like this (and much worse) that I've convinced myself never to start a plane AND hold it back at the same time. I either use safety benches, which all of my clubs now have, or if I need to start it on the ground, I use a couple of very long screwdrivers as "stakes" for wing hold-backs.

RE: 2.4 Ghz For Boats
I believe with the DX5e, you can bind multiple receivers to it with no problem (i.e. you don't have to rebind when you switch to a different boat/RX). You may have to retrim or adjust the reverse settings for each model, though, depending on how you set them up.

RE: Rx battery pack questions
I use 2200-2400mAh NiMH A cells in my packs. Usually get them from cheapbatterypacks.com (have them made up under the custom packs menu). I have four cell packs in planes with standard servos, and 5-cell packs in planes with high-torque MG servos. The A cells have higher current draw ratings than AA cells, and are just a little bit larger.

RE: Rx battery pack questions
The other argument is this: It takes the same amount of power to move/hold your control surfaces regardless of whether you have a 4 or 5 cell pack, so the amount of power you use should be the same. Since a 5-cell pack has 25% more Watt-hours than a 4-cell pack of the same capacity, you could actually get longer flight times. However, since the servos move faster with the higher voltage, you'll probably be burning more power for the extra speed, and as mentioned above, if you stall out your servos, you've got more power/torque with the 5-cell pack, and you will burn more power while stalled. So the question is, does the extra Watt-hour capacity of the 5-cell pack make up for the extra power used due to increased speed or stall conditions, or not. From other threads I've read, the concensus seems to be that 5-cell packs last about the same, or just slight less than the 4-cell packs. I've used both, but have never done a comparison. I usually only run my packs down to 40-50% capacity anyway before I recharge.

RE: Rookie U-Can-Do 3D FlightFlex EP Dilemma
I've found that brushed motors work in slow-fly type planes OK, but for aerobatic or 3D planes, you need a really need a brushless motor. Every plane I've flown with brushed motors had marginal power:weight ratio. When I pushed the power up a little for better performance, the brushed motors ran very hot and didn't last very long. I've got one of those U-Can-Do foamies myself, but haven't gotten it RTF yet (too many other planes to fly and projects to do). I've got a Himax BL outrunner for it. I wouldn't even consider using the brushed motor/gearbox that came with it. As cheap as BL motors and controllers are getting (especially with HobbyKings prices), it's just not worth messing with brushed motor systems, IMO.

RE: Quality Prop adaptors where or who has them?
Sounds like you have the set-screw type adapter. Unless you have a flat spot on the shaft, those are hard to keep tight enough to keep them from slipping. A collet type type adapter would be better. If it's an outrunner, you can use the prop adapters that bolt on to the rotating housing of the motor. You can either grind a flat spot in your motor shaft to accept the set screw (if you don't have one already), or use some blue loctite on the set screw AND the adapter/shaft to help keep it from slipping. If you already have a flat spot on the shaft for the set screw, and it's still coming loose, then some blue loctite on the set screw is all you need. In general, set screws like that on motor shafts or drive shafts in any type of RC vehicle need loctite (cars, boats, planes, etc.). Motor vibration will work them loose otherwise.

[quote]ORIGINAL: Rodney 2.4GHz antenna are not just a wire. They are coax cables with the last 1/4 wavelength of the inner conductor exposed... [/quote] That depends on the receiver. Many of the Spektrum receivers just have short wire antennas sticking out of the housing. Some of the newer Spektrum receivers have longer coax antennas with just the last inch or so of antenna wire exposed. See the photos below. The short wires sticking out are just wires, not coax, the longer ones are coax with the actual wire antenna sticking out of the end. But as Rodney said, the antenna length is critical, so don't mess with it!

If it's an unregulated supply and you are seeing ripple voltage on the output at high currents, then an additional cap will help. However, at 25A, you'll need a pretty big cap to make much of a difference. I've got a 24V 20A unregulated supply that has a filter cap the size of a soda can! Is this a switching supply, or a transformer-rectifier-filter type supply? How are you measuring the output voltage, & seeing it vary from 13.8 to 16.6V? Are you looking at it on an oscilloscope?

RE: on board glow/backup rx battery?
The Sullivan on-board glow driver he is using runs off of 1.2 - 12V, so he can use a 4-5 cell receiver pack for it. The idea behind using this on-board driver unit is that you do NOT have to use a second glow driver battery, it can just run off of the receiver pack. IMO, it's best to have a separate glow battery, since that is high current draw. If it turns on for extended periods of time, it will run your receiver battery down pretty quickly. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXRYK2&P=ML I've seen guys just make up their own single cell on-board glow systems. They put a single sub-C cell in the plane, with two switches, one turns on at low throttle (idle), and the other is just an on/off switch on the side of the plane for starting. That let's you turn it on to start it, then the low throttle switch (wired in parallel with the starting switch) turns it on when the throttle servo is at the low throttle/idle position. It's a little more work, but it will save you $53 over buying the Sullivan unit.

RE: on board glow/backup rx battery?
The idea behind having a separate on-board glow driver battery is to be sure the glow driver doesn't run down your receiver battery. If you connect the two in parallel, the glow driver can run them both down. Kind of defeats the purpose of having a separate glow driver battery.

RE: Spektrum AR6110 Parkflyer Rx
The 6110 is just a new version of the 6100. It's a little smaller and has the antennas at right angles to each other. Don't expect any more range from a 6110 than the 6100 receivers. It will work fine in park flyers, but if you have a plane that you plan to fly out at extreme distances, get a the AR500 or better full range receiver. I have AR6100's in a pair of Strykers, and I fly them out pretty far, but ParkZone puts the AR500 in the Radian (sailplane) and the new BNF BL Mustangs (39" wingspan park flyer).
