Selling my Wind 110
I'm selling my Wind 110. I'm offering it over at RCG but I know a lot of pattern guys frequent this site. I just have a well established trader rating over there and for that reason I thought it made more sense to list it there. Here is the link. Thanks for looking. Mike

RE: Props for Hacker A50-16L 10S
Downline breaking with the 17" prop should be better. It's a little slower on the top end as you might imagine. Current is still very reasonable. This is why I keep saying 12S would fly so much nicer on the 2M ships. It gets that current level down and everything runs so much cooler.

Warning: MotoCalc was unable to determine a throttle setting for hands-off cruise airspeed, so the best lift-to-drag ratio airspeed and throttle setting will be used instead. Inability to determine a throttle setting for an airspeed usually means the model is not capable of reaching the required speed with the given power system, or the airfoil information has not been specified correctly. Power System Notes: The full-throttle motor current at the best lift-to-drag ratio airspeed (50.2A) falls approximately between the motor's maximum efficiency current (44.4A) and its current at theoretical maximum output (580.6A), thus making effective use of the motor. The voltage (35.8V) exceeds 12V. Be sure the speed control is rated for at least the number of cells specified above. Possible Aerodynamic Problems: The diameter (17.0in) to pitch (8.0in) ratio is greater than 2:1, which will result in reduced propeller efficiency at flying speeds. An appropriate smaller diameter, higher pitched propeller would improve this. Aerodynamic Notes: The static pitch speed (67mph) is within the range of approximately 2.5 to 3 times the model's stall speed (23mph), which is considered ideal for good performance. With a wing loading of 18.6oz/sq.ft, a model of this size will have trainer-like flying characteristics. It would make an ideal trainer, for use in calm to light wind conditions. The static thrust (289.2oz) to weight (116oz) ratio is 2.49:1, which will result in extremely short take-off runs, no difficulty taking off from grass surfaces (assuming sufficiently large wheels), and vertical climb-outs. This model will probably be able to perform a hover or torque roll. At the best lift-to-drag ratio airspeed, the excess-thrust (176.4oz) to weight (116oz) ratio is 1.52:1, which will give very steep climbs and incredible acceleration. This model can easily do consecutive loops, and has sufficient in-flight thrust for any aerobatic maneuver. General Notes: This analysis is based on calculations that take motor heating effects into account. These calculations are based on mathematical models that may not account for all limitations of the components used. Always consult the power system component manufacturers to ensure that no limits (current, rpm, etc.) are being exceeded.

RE: 18x18 - 20x20 prop 10,000 rpm
Are you sure about being able to tailor the gearbox? There was a time when most gear box equiped motors were offered in a handfull of gear ratios. Last I checked 6.7:1 was all that was available. I do know at one time Neu and Hacker both offered 5.2:1 because I owned that ratio from both MFGs. The most flexable gearbox out there is no longer made. It was from MEC and they offered a wide range of pinions and 3 or 4 different spur gears. They were loud but they made your motors very flexable from one plane to the next..... These days motors are basically one trick ponies.... give or take a cell. [quote]ORIGINAL: 2Sunny A Plettenberg 30-9 on 12S would put you in that range: 3.7 volts nominal x 12S = 44v 44v x 235 kv = 10340 RPM theoretical subtract 10% for estimated actual and you have 9500 RPM more or less and then I would say based on a 20x13 using 90 amp I'd ballpark a 20x20 at 120 amps which puts you over 5000 watts output. I'd bet the Pletty can handle that for a burst, but that'd be a heck of a load if it was constant. On the flip side a Neu F3A would do the same and you could tailor a gearbox to your exact specifications. Both motors are available at [link=http://www.f3aunlimited.com/webstore/index.php?main_page=index&cPath=9&zenid=h4n8u6qvi9lcfu2up6edpgcn41]F3AUnlimited.com[/link] Joe [/quote]

I just noticed something in my calcs above. I typed in the ready to fly weight, which means the plane I have shown above (Wind 110) is way too heavy. Motocalc wants the weight input sans the power system and then it adds the power system weight into the calcs itself.

RE: Props for Hacker A50-16L 10S
I'd try both of of those two above and check your current draw and watch your motor temps closely. I might also consider cutting a 17x10 down to 15.5x10 and see how that does. Motocalc predicted 8 pitch props it to be below 70 mph. I don't think you want to fly it that slow. APC doesn't make a 9 pitch prop.... at least they didn't last I checked.

To me the ideal E-motor is one that is very efficient and has good bearings and good cooling. Offer it in several winds for 8S and 10S so that the 110 size planes as well as the 2M ships can use it and people can play with props. Make it easy to mount bolted to the front of a firewall or to the back of a nose ring. Make it an outrunner too. Weight isn't so important to me as long as it's not outrageously heavy.
