Has anyone electrified the GP "COMBAT" P-51 or Corsair?

Greg Covey

A power system like that used in my [link=http://www.gregcovey.com/wipa_firecat.htm]Wipa Firecat[/link] would provide excellent performance in the [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGJY9&P=ML]GP Combat P-51[/link]. Use a newer Lithium power solution like the [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLPD5&P=ML]Cellpro Kokam 3s 3200 pack[/link] and soon to be released [link=http://www.fmadirect.com/new_applications/comingsoon/index.htm]Cellpro 4s balancing charger and DPM[/link].

[ul][*] AXI 2820/10 motor[*] Jeti 40-amp ESC w/BEC[*] APC 11x7 prop or 3-blade 10x8 prop[*] Cellpro Kokam 3-cell 3200mAh pack
[/ul]

Good luck!

I have great planes P51 with an OS surpass .70 4 cycle, how would the electric convert compare? I've been out of the hobby for awhile now, when I was flying all the electric stuff was way too wussy for me. I want at least 120 MPH...

Greg, have you ever had any cooling issues with that combination? I'm in the process of determining the power plant for my GP Combat Corsair, trying to decide first whether to go outrunner or geared. The newer generation of outrunner (Axi 2820, E-Flite Power 25) seem to have overcome the "small prop needed" issues the older generation had - so I'm not sure I _want_ to go geared (2025-4100/4:1 was my best choice I think)

MotoCalc seems to think the combination you have in your Firecat will run hot - but then MotoCalc is notorious for being inaccurate with outrunners.

1/12 F4U should have an 11-12" prop to be scale - I'd like that.

Hi guys, was looking into going electric with the corsair.

Kinda stuck picking the right motor/battery combo, can anyone help?

I was going to do this until I realized that an O.S. 32 schnurle ABC would fit in where the .25 was sopposed to go.. I did this + added a rudder servo.. This thing is a real HOOT.. awsomly fast and will knife edge all day... I don't have a radar speed on it but people tend to move behind the fence line and the club stand when ever I fly it. I also fitted a 6 oz tank so I can get over 10 mins.. I don't think electric performance could ever match the .32. I like it so much I ordered a spare .32 just in case.....

lulubelle

look at the eflight .60 electric motors. with the right battery, you could do better than a .32

I'll stick with the .32 for now, if this thing gets any faster, the wings will fold!!!!!!!!!!!!!!!!!!!!!!!!!!

So i went with the AXI 2820/10 and Kokam 3-cell 3200mAh.

The AXI might be alittle over powered this frame, but having the extra power is SWEET!

SO how much flight time do you get with that setup? THANKS

loki_2525

Been keeping my flight times around 9-12 mins at 60-70% power with AXI setup.

Also converted the p-51 to electric with a Hacker A30-16m and kokam 3s1p 2000mah (15c) . The p51 doesnt track half as nice as the corsair does, going to try a hacker A30-28s with the 30 amp speed controler. This should shave another 1.9 oz off the AIW.

Hey,

Thanks guys for starting this thread. I have airplanes coming out of my kazoo and the last thing I needed was more ARF kits. However, I do have a few too many Axi 2820 motors and by reading this thread I now have ordered a combat Corsair. I had to have someone tape up my hands to prevent me from ordering the P51 also.

Please call Hobby Lobby and claim your commission, because I spend lot there and you guys talked me into spending more. LOL

Since you guys talked me into this, how about posting some flight reports with videos. LOL
