Default new flyer from Alberta Canada

Hi there my name is iain, just purchased a PZ UM spitfire because I've always wanted to
get into the rc game. So far only flown once ( broken the landing gear off, which is ok they
glued back on). Finding a place to fly is challenging, last night I flew
at a local skating rink in -26c so if all I broke was some taped on landing
Gear I think im doing ok. Just thought I'd introduce myself I am very excited to
become a member of this forum and meet all you fine chaps!

Cheers!

Im too poor for a computer so im going trial by fire, mostly t akeoffs,
short flights and landings right now, when I get a decent handle on it ill
post videos. Spent all nice taxiing it through an obstacle course in my
basement last night to get a feeling for throttle response. This is
much more difficult, but much more fun then an rc car :-)

bigmac,

If you're were flying on ice they would call you a "hoser" Just kidding.

Welcome to WF ! There's lots of help available here, from a cadre of experts ( my not included) free for the asking. No question goes unanswered so don't be shy in asking.

The UM's would not have been my first choice as an entry level plane , especially, a Spitty , with it elliptical wing. But it seems like you've gained some early success. Does it have the gyro ? Normally, we start with a high wing trainer like an Apprentice or even a HZ Super Cub. But, whatever floats your boat.

Best of luck !

Hawk

A Sim like real flight or Phoenix is a good idea as is buddy boxing with an experienced pilot.

Yes I did some research that advised against it, but it has the as3x system
onboard, and the up wing Cessna models just dont make me smile
like a spitfire. its definetly challenging, been reading up lots on it.
first few flights I used very little aileron and it went ok.
Im sure I will crash it but at 77$ and its small size you cant go wrong!
Before this plane I almost bought an eflite 540qq, glad I didnt get that one...
spit is hard enough! Thanks for the warm welcome!

The ice had a couple inches on it, seemed ok the boards around the rink were the real
issue!

I am happy to report my first real maiden flight in an open area went very well!
Launched off the roof of my truck with a board, even managed multiple
barrelrolls and a hammerhead, I think my experience with video games
may have helped me control it, amazingly responsive and agile
perfect speed, trims were great out of box and not a single un intentional
stall, I think im in love :-)

Update, the plane was crashed, replaced a wing and a new prop.
the old prop was 4 grams! New one is less then a gram, tried my hand at
clay balance! Is there a chance installing a lighter proper could be detrimental
to engine performance? I wouldn't think so, but my first flight after
Installation the plane kept hitting lvc very early across 3 different fully charged
Lipo. Changed all batteries, labelled them and charging them now.
going to go try again soon with a flight timer.
could less than perfect batteries in the transmitter cause early LVC?
Manual states LVC is for flight battery only. .

LVC is all about the flight battery. As for a lighter prop, being that much lighter makes me wonder ifit flexes and possibly flattens under load. Another consideration, is the new prop the same diameter and pitch as the old one? It can be drawing a little more amps than your old prop, or it may even cause the motor to pull more amps than the esc or perhaps the battery can deliver in worst case scenario.

If you crashed and damaged the prop, what else did you damage that you may not know about. Is it possible the motor or the spinner are rubbing against the body of the plane? This would cause extra drag and drive up the power draw. This could cause voltage to drop below LVC.

Is it possible you bent the motor shaft? This would cause the prop to spin unevenly which would put tremendous pressure on the bearings. This would cause heat build up which would swell the bearings, binding the shaft and causing a voltage drop that would kick in LVC.

Check the motor, the motor mount and be sure nothing is rubbing or wobbling. Finally make sure the new prop is not bent. Also make sure it is the same width and pitch as the old prop.

I actually just re glued the motor in place, it was a bit loose but nothing was rubbing.
Took it for a flight yesterday with a new flight battery, no LVC.
I guess the service life for those little lipos is about 20 flights.
thanks for all the help guys!

If you are not over discharging them and not over charging them they should be good for at least 100 cycles and as much as 500 cycles.

Went from a 4 blade to a 2, when I get home ill measure them up.
its definitely wider across, I figured that would be ok do the fact of
2 less props, I believe the new one is slightly less angle.
Ill post it when im off work. Thanks again!
