CC, Wholly Moley. Great piloting skills getting her back safely, Sir. Best, LB

Thanks. Unfortunately, the airplane is unfixable. They sell a replacement motor mount, but I see no way to put it in without splitting the fuselage in two to remove the old and insert the new.

Here's a weird one. I put in the upgrade KV650 motor and ESC and flew it a few dozen times. Yesterday shortly after takeoff it started making a nasty sound, and before I could get it landed the motor separated from fuselage. I managed to deadstick the motor-less airplane to a safe emergency landing.

The motor mount shows the motor appeared to overheat so hot it melted the mounting bracket and the screws pulled out. At least that's what it looks like. Immediately after landing I could touch the ESC. It wasn't hot. Just warm.

The motor came off a couple hundred yards away over some scrubby area. We searched and couldn't find it.

I have recently purchased the V8 redtail but I am experiencing issues with the rear retracts not working. They don't cycle either up or down with the main landing gear. What i am looking for is a picture of the FMS multi connector board showing me what leads go where as the schematic diagram in the manual is very poor. Im not sure that I have the connector in the correct position. Any assistance would be appreciated many thanks.

Yep. I ordered some extra prop blades and a spinner last night. With 5 Mustangs, you can't have too many spare props... LOL

Hey, now that's a good idea, I'll have to check in my stock of old landing gear and see if there is something with the same diameter. Unfortunately, this might be a hint of things to come. Try finding gear doors and such. We may be seeing the end of out favorite airplanes.

[Hardway]

RC Castle has these too, but for just the pins...…. I came up empty too. IDK if they are 4mm, but whatever the diameter, use some old nitro wire landing gear or music wire and cut your own with a Dremel and file the flat spots with the abrasive wheel.... Sorry Bro!! I tried!!

[Grossman56]

Anyone know of a source for the retract pins? I've sourced out Motion, FMS and Horizon, but none to be found.

Check into the aluminum retract sides from Smallparts CNC. They're awesome.

You'll break a wing before a retract side

Also, I replaced the aileron and elevator servos with metal geared servos.

My P-51B lawn darted earlier this season, but I rebuilt her and she's flying again. From this...



Back to this

Yep, it can be done!!

Very nice repair job. Like to see the modelers that come out after a crash! I do have the CNC retract plates already, almost forgot about them.

Everything cycles correctly but lights. Got me stomped

Followed all instructions to hook up. New plane. Did not try anything out of normal until no results. Wing lights and landing lights not working.

The only thing I can think of is the polarity of the LED plugs. If those were inserted correctly (red wire to positive, other wire to neg.), then I can't see anything wrong unless the LEDs are duds but they can't ALL be duds. Do AIL, gear and flaps work like they're supposed to? One of those supplies power to the lights through that white box.

I hope mine are still flying after 4 years. I have Snoops Sniper, Dallas Darling, & Big Beautiful Doll. Bought a couple spare props, spinners and retracts along with the aluminum spinner back plate. Should be good for a while I think/hope!

My BBD is also 4 years old and still flying really well. In this video, the plane was about a year old and had just gotten the higher kv motor transplant. It currently runs the 6 cell drivetrain from the P-47.

Anyone having problems with lights on Freezing P-51 Old Crow Mustang? Can't make mine work either using the year sequencer or direct to receiver using Aux channel. Tried a second new lighting module, still no luck. Wired per I installation video from Motion RC. Need help

Did they ever work? Some of these LED lights don't work well if hooked up directly to a RX or to a servo tester. Too much juice. If you did that first, they may have burnt out right away. Also, if you hook them up with the wrong polarity, they can burn out without showing any light. Then, if you put them on a light module, they may already be burnt out.
