Question hangar 9 corsair gas to electric

Looking for some recommendations for converting my hangar 9 corsair to electric. Currently it is set up with a Sato 100 that I am going to remove and sell. Trying to decide what motor, speed control and battery setup is best and most affordable. Any help would be appreciated. Thanks.

Good call swimmer. You may want to check out the equvilent of those part, motor, esc, and the battery. $249 for a 5 cell is a little out of my style and I believe it can be found a lot less that that at Hobby King.

Not going to be cheap, I've got an old Goldberg Extra 330 (78 inch wingspan, 16 pounds, 1200 sq in wing) that is being converted to electric power. Bought it brand new out of the box from the local hobby shop for $75 less than they paid for it! It's running a Hacker A60-16M motor, 12S2P A123 2300 cells, which turns a 19X12 APC-E prop at 6700 RPM. That's about 2400 watts. This has the power of a good 30-35 cc Gasoline engine or about a 160 glow engine.

You might look at the Hacker A50-*L motors (Long frame) , or the A60-"Short Frame" motors. These motors have a number of different windings available, to help with your power selection. http://www.aero-model.com/Hacker-Bru...By-Series.aspx

This can be a real guessing game without help. Check out www.motocalc.com for this, its free for 30 days, then its $39.00, and worth every penny. From what I've been able to tell, motocalc gives accurate results using the various Hacker electric motors. Ran into some problems awhile ago with some of the other high powered motors, where their specified motor specifications were not even close to what the motors would actually do.

In particular with www.motocalc.com, look for the predicted motor efficiency, prop air blast speed and rate of climb with your power system and model. Any motor efficiency below perhaps 85% can be a problem when you are getting into the higher powered equipment. Low motor efficiency means bigger batteries for the same performance, and weight can be an issue to watch for the larger models.

If you don't have one all ready, you will need a wattmeter to verify your motor/esc/battery results. One good one is the Astroflight Whattmeter. Many others are available. It is easy to overload these motors/esc/batteries by the wrong prop selection, and if really overloaded, it is easy to let out the magic smoke on your motors. A whattmeter will let you know real quick of you've overloaded your motor, or even underloaded the motor, resulting in poor flight performance.

Perhaps the following threads will be of assistance

How fast do you want to go and how much thrust do you want? Or as my bud's say how stupid can you go?
Here's my Top Flite version, little bigger, running an HTX 63-64 motor 280 kv, Suppo 100 amp esc, and a Flight Max 9S 5800 30C pack (4S/5S series wired), and under $225.00 total.
Spins a 14 X 12.5 X 4 prop or a 16 X 10 X 3.
20 pounds of thrust and right at the century mark for speed in a 13 pound bird.


Or I have a World Models version on the bench now for a rebuild. Victim of a loose prop and the owner was going to toss it. Easy fix, but anyhow it's running a Turnigy
50-55A 400kv motor, $30.00, Suppo 80 amp esc, $67.00, and a pair of 3S3000 Turnigy Flight max packs wired in series for 6S, $34.00 for both. Spins a 14 x 10 APC prop.

Flies really nice, good speed and great thrust, for under $150.00, in a 6 1/2 pound version.

Just to show you don't have to spend big bucks to get good performance.

What's a "Swarm Buy", Gramps and how does one find it on their website?

Thanks... The Bum

Default Electric Set Up

I purchased the H-9 60 size P-47 and making it electric. Using a NUE 1515/2Y 15.5X12 4 blade APC prop and 2 5400mah in series. Still in the build. I used this similar set up on the Thunder Tiger Sea Fury using a custom 5 blade prop from Zinger 16X14. That plane is off the ground in no time and really nice low high speed passes with the coolest sound. I use an aluminum motor mount that I found in the Tower Catalog. I am having trouble getting my pictures on here.

Default My Hangar 9 60 Size Corsair specs.

If you haven't started your conversion yet, you may want to consider what I've done. I have 4 large electrics all flying on the same setup. One of them is the Hangar 9 60 size Corsair.

Motor: Hobbypartz.com Monster Power 160 size motor ($55)
Prop: APC 16 1/2" x 15 E-prop (Cut down from 20"x15 APC E-prop)
ESC: Hobbywing HV 12-cell 100 amp esc from valuehobby.com ($95)
Batteries: XPS 3 & 4 cell 5000mah lipos to get 10 cells, best lipos for the money (extremepowersystems.net)
Servos: Power HD 1501MG servos from valuehobby.com ($13.50 each)
BEC: Castle Creatiions 10amp bec for $20. (I use a 3-cel lipo with it to run my receiver on 6volts and it runs awesome)
Retracts: Hangar 9 stock ones
GoSlow: This will slow down the speed of the retracts. It works awesome with a standard size servo. I use one for each retract.

This setup will give you peak 3000 watts input. The plane will go 120 mph top speed drawing max 85 amps (not a problem with the XPS lipos). I get 5-5:30 flight times flying agressively and put back 3000 - 3500 mah back into the packs during charge. Your choice of TX and RX is yours, but I use Airtronics 2.4ghz on all my large planes and it's great.

If you're looking for speed without breaking the bank, the above setup is perfect. I thought spending big money was required to get good performance, but that's not true for today's technology. I have an E-flite 160 motor, which cost 3x the hobbypartz 160 motor, and it doesn't give me any extra power or speed. I tried different components on a lot of planes to arrive at this setup.
