P-39 Airacobra A Short History

P-39 Airacobra A Short History
The P-39 Airacobra is a unique fighter aircraft from World War 2. Designed by the Bell Aircraft Company, the P-39 had the engine mounted behind the pilot, tricycle landing gear and a 37mm cannon that fired through the propellor driveshaft. All unique attributes to this aircraft.
About 9,500 P-39s were built over the course of the war. 4,800 were sent to Russia under Lend Lease, where they proved effective in the low level air warfare of that theater. Due to a lack of a turbocharger, the P-39 could not be used at altitudes above 15,000 feet.
The P-39 model shown is from the FMS model airplane company. The model is essentially ready to fly with just the controls needing to be connected. For a full review of this kit:

Nice, I always like to see the connection between the hobby and real planes.

Thanks for checking in! Tim

Great presentation on the P-39. My father flew both the P-39, and P-63, during WWII but didn't have much good to say about them. He said both cockpits were cramped and small, even for a 5'10" pilot, and he was fortunate to never have to bail out of one because of the door.

[@TimMcKay56]

Thanks! Agree, bailing out would be a nightmare. 😳🙈 Tim

Good overview. Having the engine near the CG brought the center of mass closer to the CG which helped with maneuverability. But, the P-39 had a tendency to become tail-heavy when the 37mm ammo was used up and they would snaproll unexpectedly. The P-39 Airacobra and the P-40 Warhawk were the best fighters we had before WWII started. I've been wanting a P-39 ever since the P-63 collided with the B-17 at Dallas. I wish I could find an NIB E-flite P-39. It was a little larger than the FMS version.

Great points, good luck with your search! Tim

beautiful design!

Great video. I was aware of the p39, but did not know much about it. Hope you do more historical aircraft videos particularly in the WWII scale area.

[@TimMcKay56]

I will certainly add to my list! Tim

[@RebelByNature]

@@TimMcKay56 You know what else is super cool imho, is the FPV RC plane stuff using goggles, presumably a spotter, with head tracking so you can look around (camera in the cockpit moves in two axis based on your head movement). Curious what it takes to do that, equipment, cost etc. Just an idea.

Nice history of rc plane, Brother

Thanks! Tim

Respectfully disagree with our turbocharger statement. Only some American planes had turbochargers (P-38, P-47, B-17, B-24 and B-29). All the other combatants in WWII had single stage engines and were able to get adequate high altitude performance. The British and Americans did have two stage supercharging which used a second stage mechanical supercharger instead of a second stage turbocharger for superior high altitude performance. The main problem with the P-39 was excessive weight which was easily corrected. Remove the .30 caliber wing guns and some of the excessive armor plate and P-39 performance was on par with the Me109 and Fw190 at all altitudes.

Hi there, Tim. I need help with my bnf umx, for some reason earlier it would bind, but then the control surfaces would freeze and a red led would begin blinking, i restarted it several times, then it stopped binding completely.

[@TimMcKay56]

I think if the light is blinking, receiver is looking for a transmitter signal to bind with. Ensure you do this correctly. On the DX6, you hold the TX bind button as you turn on the transmitter. We sure to point the TX antenna away from the receiver, this seems to help. Tim

[@alexherrera3918]

Nice review. Do you prefer spektrum SAFE or FMS reflex?

[@TimMcKay56]

Thanks! I do not use SAFE or Reflex, cannot offer an opinion. Tim

[@txkflier]

The FMS Reflex works very much like Spektrum's AS3X/SAFE, but the Reflex software will only let you configure them for FMS planes. It's almost impossible to put a Reflex gyro in a non-FMS plane. On a 3-position switch, the Reflex gyro has Off, "AS3X", and "SAFE". FMS doesn't use those names, but that's how it works.
