I had bought a PNP EFlite Mini Ultra Stick almost a year ago (the PNP version now discontinued, while the ARF version remains), and I actually maidened it this past week. I had put off maidening it because it was my first balsa plane and I was leery of crashing it and also because I was missing some nuts for the landing gear and the tail section and couldn't find the low/high rate recommended deflections for the MUS in its manual, which I thought was strange. I did find them here, which in this version strangely has the recommended throws. I just couldn't find them in RC Groups on the MUS threads, and assumed that looking up the PDF wouldn't have them either since mine didn't. I was wrong.

Anyway, I did 3-4 more flights in the second outing after the maiden, after I fixed my tail assembly (it had kept fishtailing, so I had only one flight on the maidening day): at home, I discovered that the tail gear fixture had come loose. I cut out a little of the monocote and wicked in thin CA into the screw hole (not the long tail screw hole, holding together the horizontal stabilizer to the vertical stabilizer, but the second screw hole for the Du Bro tail assembly) and on the bare balsa and attached the plastic tail wheel guide and screwed it into place. Solid now. No fishtailing at all.

The warped wings continue to have trimming problems and it seems to warp a little more this way or that way every outing, though not much between flights. (The pictures below show how much trim...Continue Reading

I flew my PZ UM P-51D for the second time this weekend. I am using my P-51 as an aileron trainer, after having mastered 3-channel flight with my PZ J-3 Cub (switched out with a DSM2 rx for use on my Spektrum DX7). I understood what other people meant when they said that the PZ T-28 is a much more relaxing plane: I can fly the J-3 in some fairly strong wind of about 8 mph without losing control or at least not crashing it (even with some successful sailplaning with the power off at 300 ft). Even though I don't own or have flown a T-28, the UM P-51 as an aileron trainer is very difficult to fly.

I think that the biggest difficulty is not anything to do with the plane itself and its mechanics, but with its size. I flew it very well at about 150 feet in the air learning aileron turning, trimming and such (when it veers/yaws to any one side, its because of the rudder and not the aileron trim being off, but if its rolling a bit first before turning, since the lift alone will turn the plane in a bank attitude, then it's the aileron trim that needs to be adjusted). I kept losing control or kept over sticking it because I couldn't tell what direction or alignment it had in the air. But, to fly it closer to the ground (so that I can see all that) results in lawn darting it into the ground.

I must have crashed at least 30 times that day going through about 5 PZ 150mAh batteries. Not having taped the batteries to the fuselage resulted in ripping the connectors off when it crashed...Continue Reading

Last Sunday, I took out my PZ Vapor and flew it outside. When I had flown it indoors in my complex underground garage three weeks before, I had broken the prop within seconds.

In preparing for the flight, I saw that the wing had indeed come off of the carbon wing frame, as one of the Vapor threads had pointed out. I glued the plastic film to the carbon rib with white glue, as I remembered someone posting that CA glue can melt the carbon tubing.

The wind was almost nothing that day, so I ventured outside to fly the Vapor only a few days after getting my (four) replacement props in the mail. I had four LiPo batteries total, one stock and three ordered with the Vapor from the supplementary listing of accessories. After having flown the PZ J-3 Cub two times so far with not much success, I found the Vapor surprisingly easy to handle and I got used to it very quickly. I bought the BNF version, and I was using my DX7 thoroughly enjoying the idea of using my DX7 tx finally.

I hand launched the first few times, and I had given myself a soccer-field-sized flying area, remembering my confined space before had caused me to break my prop. I did take the Vapor out into wide turns using up most of the width of the soccer field to do so, but I got comfortable enough after my first few minutes to confine the flying to right in front of me in a 20 meter by 20 meter space. Three mistakes high for the Vapor is about two people height: even if it stalled, it only took about a foot of "...Continue Reading

Glad you had a good flight other than the tree and found your hand launch trouble.

(From "Hand Launch J-3 Cub bl help." Thought I should start a new thread so as not to hijack that one, but then thought better of it and took it down from the forums to put up in my blog--didn't know I had one).

I thought that the tree quip was metaphorical, like "the hand of God will swat thee." Not, I learned.

I am a newbie: no flying experience ever, though I had often read about RC planes since my teen years a few dozen years or so ago and had a few hours of FMS sim time recently. (Yes, I know that the HZ SC would have been better, but I wanted a quiet BL that I would upgrade to eventually anyway and that spring throttle, I read about that one, and and and)

I maidened my PZ J-3 Cub BL yesterday (I say the full name in reverence to the J-3 ghosts of mutilated trainers past loitering around and bewitching mine still ). I came prepared after having read and reread the rcgroups posts and the instructions and having two extra 8x6 APC props, that size as recommended in Spackles' review (great review btw), and no less than 8 extra LiPo batteries, charger, 12V field battery.

Let's...Continue Reading
