I can definitely make a model and print it myself! The link to thingiverse is definitely a different plane, but thanks for reminding me that I already have this skill…duh

I added a cannon to my collection of Spitfire parts:

Flying today and the grass was very wet and soft. Unfortunately my Spit tipped on its nose at full power and I think the bearings have gone in the motor because there is a slight wobble on the prop shaft and a knocking noise at high power.
Can the bearings (or whatever it is) be replaced or is it a new motor 😫😫😫

I'd suspect a bent shaft, but hard to know without seeing it.

oK thanks, are they easy enough to take to bits.
I see there’s a split pin at the back of the motor, does that allow the shaft to be removed?
sorry, I mean clip not split pin

[Evan D]

Yes remove the clip, check for thin washers. And pull the halves apart.

My Spit nosed over during take off when the grass was too wet and soggy. Since then it’s been making this knocking noise at high power settings. I thought the bearings must have gone in the motor, but I’ve tried it with another club member’s motor and it ‘knocks’ with that motor too. So I’m now wondering about the ESC, would the ESC cause the motor to make a knocking noise ?

I wouldn't think so. Did you check the prop balance after the prop strike?

Thanks for the reply. A friend of mine has a Hobbywing ESC programmer and when he connected my ESC and motor to it, it showed the timing set to Low. He changed it to Medium and the knocking and hunting at high revs has gone, so hopefully it’s now sorted.

[paladin]

you sure you don't have a loose magnet in the motor?

[xviper]

But it was set to LOW before the prop strike and it didn't do the "knock" before. Changing the timing to something else may just be masking what is really wrong. I'm guessing a damaged prop/prop assembly, or damaged motor mount.

I’ve put a new motor in it and it was still doing it with the new motor and that’s when I decided to have a look at the timings and suspect it was the ESC. The motor as well as knocking was slightly hunting at high revs. That’s all gone away since I changed it from Low to High

If anyone knows where I can buy one or more of the plastic 20mm cannons for this plane, I’m in the market. I just discovered that MotionRC is out of stock. I lost one this season. If you have an extra, I’d be happy to pay.

I've got a set sitting around, PM me and I'll send them to you if you live in the USA, if not, I'll need money for postage.

Kallend, thank you sharing your Spitfire STL Files. Those are great designs and the most needed parts. Best, LB

[paladin]

my spit has picked up a tail wagg. when holding the wing the bottom facing me i can move the empennage left and right pretty easily. i take the wing off and it still moves pretty easy but no cracks or anything out of place. any one seen this before i glue the wing to the fuse in that area?

Sent. Thanks.

The grass was wet and ground very soft. During take off the wheels dug in and the Spit dug in its prop at high power.
Next flight the Spit motor made a high pitched whine and a knocking noise at high power. It was also so underpowered I nearly stalled it on take off.
I bought a new motor because I thought it must have damaged it, but still the same problem. I never thought it could be the ESC but after 2 weeks of head scratching I decided to change it. Now it’s as good as new and back to full power. So lesson learnt, tipping over on to the prop can damage your ESC.

Merry Xmas to me!!!! Starting new winter project in days!! I will see what mods I will do on that Spitfire.

[Simon Bee]

👍 Mine looked so gorgeous after I’d built it, I didn’t want to spoil it by flying it.

PK, a dog, you lucky guy, I asked for one, too. Merry Christmas, my friend. Best, LB

Just checked the Spitfire. Nicely packed as usually we see at FL kits. I expected, that Spitfire comes with decals on extra sheet same as B-24. What a shame, that all decals are placed on. I will have to remove them. Not sure if it will peel of paints. I will replaced some parts such as exhaust stacks, trim rods, probably 20mm Hispano cannons...
