I just acquired a friend's AL37. Have thought an Iberia Airlines livery would be unique and I have flown my share on Iberia. My question pertains to upgrading the current older out runners that originally came with it, to the newer and more powerful inrunners. I currently have the original 60 amp ESCs with the 5A BEC. The current ESC on the MotionRC website for the AL37 is a 60 amp with an 8A BEC.


Would anyone advise as to whether it is necessary or recommended to switch to the newer ESCs along with the new inrunners or OK to fly with existing ESC.. In which case, would be cool to use an ESC that would do thrust reversing.

Any input will be much appreciated.
thanks

It's fine as is. IMO

I appreciate your input. Could you plz clarify if you are referring to the stock out runner and existing ESC? ....or Ok to use existing ESCs with the new inrunner.

thanks

My current al37 has innrunners,, looked last night,, it has 60 amp esc bought it new last year... if thats any help

I installed reversing esc's from Motion RC in my AL37...SWEET addition!!!

I did experience a hard lesson over again with this jet, 15mph crosswind on the ground, 20+ at 100+ft, landing approach to base, gear down, 1st stage flap, medium rate on aileron and elevator, reducing power for base, wind lifted wing and rolled jet over...won't do that again, keep speed up in heavy crosswind approach!!! It's a large surface area jet and I should have known better!!

Mines stock. Only thing I did was bypass the blue box for the elevator. I wanted more throw.

Simple fix for lowering main gears to put wings on,
I unplugged the gear plug off port 4 on board in wing and put a rc Y connector on port 4(male side) then plugged up the gear and let the other end dangle out of hole.

My maiden went well. ,just need some adjustments etc. Should not really have maidened it with the 12 plus winds but it was a nice sunny day. Def need to put a 5200-6500mah in. I did first flight with a 4500mah 50C
Overall loving this bird

Hi SR,
I used what I had handy. 2 inches in length, and small enough diameter so you can drill holes in the fuselage walls and leave foam all around the rod.

2 rods embedded length wise on either side of top dead center and going across the fuselage joint is all it takes. Go about 1 inch “into” each fuselage “half”.

If you want to avoid top wing skin cracks that will happen after a lot of flying, remove the motor nacelles from the wing so you can get to the wiring channels in the wing. Flip the wing over so the top wing skin is on the work surface. Cut as long a piece of about 1/4 inch square carbon rod that you can fit into the length of the wiring channel and epoxy the rod against the inside of the top wing skin. Use 5 min epoxy because you will need to press the rod against the top wing skin while it cures.

If you elect not doing this, after a lot of flights, she will look like this…..

Hi GliderGuy

the carbon rod you recommend to put in the cable channel, did you put it parallel to the wing spar tube, or at an angle in the channel? See attached photos of how i see the tube fitting in the channel.

Cheer,

Can anyone advise how to place your 6000 battery and are you satisfied with the CG?

I did no cutting or drilling…,simply followed the wiring channel. It is thusly angled.

You’ve got the right idea. Make sure to put top skin against the work surface and press down on both ends of the rod while the epoxy sets.

This makes a HUGE difference in reducing top skin stress cracking over time.

Agree with F4U. Balanced mine on the factory CG marks. Then with centered stick…manually adjust elevator linkage to 5 mm up elevator. Using Admiral 6000.

Add a gyro!!!!
