The Magnum 52 will fly it, but not like the PRO46. Sorry i don't remember the prop size we used. On the PRO46, definitely 12.25X 3.75.

Cool so a .46fx would fly it well? I just bought one today for $10 at action. A little dammage from a hard landing but nothing 10-12 drops of CA won't fix.

prophanger,

I run an O.S. 50sx and a zinger 12x4 on mine. It has unlimited vertical and is real tricky! I am fixing to place a high torque servo for the elevator and a 4-40 pushrod on it. When I'm pulling some serious g's, the elevator rod bends and the servo seems to fail. I can hold the elevator while its on the ground and with a little preasure, the rod bends and the servo strains. Here are some pics of it.. You will really enjoy this plane!

hi got the book .


elevator high rate.7/8 up and down . low rate 1/2 up and down.


rudder high rate 1.3/4 both ways. low rate same as high rate.



ailerons high rate 1 up and down. low rate 5/8 up and down.


CG IS 3.3/8 FROM LEADING EDGE. IT SAYS YOU CAN TRY 1/4 INCH EACH WAY AFTER YOU GET USED TO IT.

Ok guys, thanx very much! I look forward to flying the wings off this "beater" plane. Any of you guys have pics of the push rods? This plane was compleatly stripped down when I got it. However I have repared the dammage.

first thing you need to do is check out the knife edge loop it is about a 10 foot circle.

Any body had issues getting the CG correct on the Fun 51? I have it set to the manual spec, but was very surprised when I mounted my old, made in Italy, ST 40 on it and had to add 1.5 oz of lead to the tail. I mounted the battery at the back of the wing and the receiver just in front of it to help. Anyway the concern is I would like to put an OS50 on it, but then I'll need even more lead to balance. I have though considered mounting the battery on the side of the fuse aft of the wing to eliminate the need for the lead.

How did everyone else's CG work out? Much lead needed to balance it.

Thanks all.

I mounted the motor back as far as it would go. It came out OK. I have a square battery and wiretied it to the block that the servo attaches too and rx right behind it. Didn't have to add any weight.

I also mounted the engine as far back on the mount as I could. What servo mounting block are you talking about? Do you mean the rails in the wings that servos mount to?

I actually got a 720 mah NiMH battery, it uses AAA cells, so I could move it back further in the wing and that did help a bit. The battery is mounted all the way at the trailing edge of the wing right now. The rx is just front of the battery. I may have to move the battery out of the radio compartment in the wing and tie it to the side of the fuse I guess. I really don't like adding weight to a plane to get it to balance. In fact other than gliders I have never had to, even after 15 years of flying R/C planes.

My real concern is that I don't think a 40 size engine will have enough power for me. A larger engine will just require even more weight.

Hmm, I wonder if the problem is with the way I balanced it. Rather than drilling a hole below the wing in the fuse I just measured the distance from the leading edge back and used my CG Machine.
