3d,

Here are some SX static RPM #s...

I've noticed that the performance of SP & SX motors improve after 20~30 break-in flights.

ps. I now have an excellent source for nano 2-pin connectors that should be arriving today or tomorrow.
Ready-To-Run SX motor orders will no longer require old stock motors to be sent to me for parts.

This is fantastic news, as my P-51 poo-ed itself but needs a new RCBABBEL SX Motor! Planning a few other mods, as well, such as 4-blade prop and no more undercambered wings

I got the Spit a couple of days ago. Today was my first chance to fly her,albit a bit windy! All I can say is well done Parkzone. The AS3x is a great bit of kit! Now I need to get more batteries.

Yes this plane made me buy new batteries as well..... the calm evenings where I can zip it around a foot off the deck are amazing. I had it so low the other day I scraped a wingtip!

Ok, after almost 4 months of nonsense trying to get a defective Spitfire replaced, it finally came last night and it works!!

I don't have time right now to read this whole thread, so could someone kindly summarize what y'all think are good mods for this little critter?

Is it common for the spitfire to run tail heavy?

Weather has only allowed 1 flight on mine so far. With landing gear and stock lipo, it felt like it was dragging its tail a little in turns so would indicate tail heaviness. However, it was still easily flyable probably thanks to AS3X.

Spitfire airframes tend to have problem with balancing seeing how close to the nose the wing sits compared to other planes. With many models, you'll see lipo and most electronics shoved to the front as much as possible.

When your spit was dragging its tail in turns, were you using rudder to turn as well? Could just be some adverse yaw you were seeing and not so much heaviness. The best test I've found is from straight and level flight, cut the throttle. If the nose drops slightly, you're ok, if the nose pitches up, you're tail heavy.

Majority of my planes are aileron & elevator only so I then to not use rudder. Balanced right, my other planes would track thru turns and drop nose if nose heavy and opposite otherwise. That said, good point with adverse yaw as I'm used to 2 bladed props. I was also doing left turns in pattern which may magnified that. I'll have to try right hand turns next time and see how it looks.

I always rudder through turns and it never looks droopy to me. Adverse yaw would come about from the ailerons, I don't know how much a propeller would affect it. However, I have to say, I did minimal adjustments to the u-bends for elevator and rudder and mine flies very, very well.

I'm thinking adverse torque as opposed to adverse yaw with more mass (blades) from this prop.

Like I say, majority of my planes don't have rudders and when balanced well, they track very nice. Certain planes limit me in c.g. adjustments so nose dropping or tail dropping is usually seen.

I'm one of the slightly unfortunate ones where mine didn't fly perfectly right out of the box. Needs very large left roll and slight pitch up trimmed out. I'm a seasoned flyer so it didn't mess me up but I can see noobs potentially crashing theirs. Don't know if I would blame PZ for poor manufacturing quality since mine could have been damaged in transit due to heavy handed delivery dudes.

This plane is only the first of my eventual many AS3X, but next one I buy will most likely need to have brushless as stock.

Mine needed the elevator adjusted out of the box. If you take your time (talking to newbies here, not yourself) and visually align all of the control surfaces by adjusting the u-bends on the control rods the best you can, then your chances of a successful maiden go waaaay up. I promise you just by mechanically trimming my Spitfire, it tracks nearly straight as an arrow hands off the sticks, with zero tx trim or subtrim. What an incredible plane
