Both my kits came with Lanxiang labeled 4S batterys (saw previous posts regarding usage of 4S packs). In one plane the rear retract servo is already broken--- the front retract servo won't retract the the gear all the way--will have to replace those. I noticed these are glued in place---whats the best way to remove them without killing the surrounding foam?
I installed and removed the gear on an ARF. I didn't glue mine in. You'll have to remove the glue best you can with maybe a knife and needle nose pliers? After that they are probably screwed in. These pics should give you an idea. It will be easier unscrewing these than unscrewing the beef with the suppliers. On the retraction problem, it might be the wire link adjustments rather than the servo, its a trial to get it all just so. Great good luck with the plane, it's fantastic and well worth the effort when you see it up there.

Registered User appears the gear itself is fine--just need to R&R the servos. The factory glued those in and I will need to find a non-destructive way to remove them.

Try pushing an Xacto knife between the foam and servo case all the way around the visible perimeter to crack the glue away from the servo case. Then it's like a dentist, grab it with pliers, rock it around and pull.

I bought one of these but now I'm afraid my feeble old brain will cause me to crash it.

Should I sell it and buy something easier to modify and fly??
