Magic Extra -- Where To Put RX & Battery?
 

She's done. The OS SX .50 fit the stock engine mount like an isotomer glove; hope I don't need to adjust for thrust, ect.

I installed all the servos per instructions. Like a few of you I found the airlon push-rods way too short -- fabricated new ones from spare stock piles.

Ques #1:
The landing gear appears to be very flimsy, even for this light weight airplane -- anyone having problems with it bending on other than significant hard landings?

Ques #2:
Where are you putting the RX and battery? I haven't checked CG yet but can't for the life of me think of putting the RX other than just in front of the wing hold downs and the RX battery pack in front of that. I'm thinking of using a Hitec Supreme SS 7-channel RX. With the standard Hitec rubber foam blanket it is a very tight fit just in front of the wing bolts. The battery seems to fit OK in front of that. It looks like the only place for the switch is right next to the RX -- might have to add extension to the battery.

Ques #3:
I've seen a lot of posts for the TT 46 and Saito 72 for this plane. Anyone out there tried the OS SX .50? What prop is best. I have both APC 12x4 and APC 12.25x3.75. I currently have the standard muffler installed on it but also have a MAC's single-piece exhaust and a Tower Hobbies exhaust available as alternatives. I also have a spare OS FX .46 if that is a more appropriate engine for this plane????

NOTE:
Model Tech did a nice job with the detail and covering material on this airplane -- I don't plan on changing anything, EXCEPT, the wheel pants have to go. They look real cheap and really don't fit the look of the airplane. Along with the wheel pants I think I'll up the size of the wheels a little and replace the screw axles with regular axles.

When I got my Magic done it was very tail heavy. I wound up putting the battery up front right behind the firewall. had to do a little creative carving on the fuel tank hatch, but it fit in very good. the rx is located in the back just above the throttle servo. I put a Magum 45 in it and had to move it right out to the front on motor mounts to get the plane to balance, after that didnt have to add any weight. I agree with you the wheel pants are kinda cheesy looking. I put a black and white stripe on them and a good coat of clear to shine them up that seemed to help with the look.

Where did your CG end up at and how did it fly at your CG.
My friend has one and it balances at 4 1/2" back of the leading edge with 3 ozs. in the nose. That is a good inch futher than recommended in the plans and he is afraid to fly it. Your help would be appreciated

:) Greetings, Neirnyck!
My magic extra balances @ 4-3/4" and I've had it back as far as 6" just to see if it would tumble. It won't. (not for me anyhow :)

The only difference I saw with this tail heavy condition was that it tended to float past the runway when attempting to land at a normal speed.

This plane has so much tail you have to force it into a spin. Although I don't reccomend that anybody fly with the 6" c.g. , 4"-5" has served me well. Can fly out of a flat spin in any attitude. But no waterfalls!! :mad:

With Saito 72, I ended up inserting the slim 5-cell 720 mA NiMH pack right under the stab, which achieved a CG 4.75" behind LE. I had to cut a slot right behind the former under stab LE. It was a snug fit with some foam. I then glued the cut slot back and covered it back up.

I thought the covering material is junk. Just tried to heat gun it; actually, don't do it. You will end up with worse wrinkle.

Mine balanced at 3 1/2 to 3 3/4 back from leading edge. This was with the engine pushed out as far to the front as i could get it. I also put the battery pack on top of the fuel tank just behind the firewall. After this no weight was needed to balance it where the spec's said it should be. The plane flew very good but did not hover very well at this balance point, so i am going to try moveing the balance to add a little tail weight. hope this helps.

Depends on what you want to do with it.

I flew mine on the rearmost blue trim stripe on the wing for 3d stuff a little in front of that for screwing around. Admittedly i spent more time with the 3d balance point.

I put my battery above my throttle servo in a tray i built and i put my reciever just in front of the wing hold down bolts

Had a 46fx mounted normally in the cowl, not moved forward or anything else.

Hope this helps

i'am doing the same set-up with the 50. started with the recommended c.g. and it puts my nimh 1100 pack right on the former in the wing saddle thinking about useing some servo ext. to move the rec. in front of the former and put the battery where the recv. is suppose to go.
