Ok here are my $0.02

Ordered my Yak 52 (54) 3D & was pleasently surprised at the quality when I opened the box.

Assembled it & it flew great with a Saito82.

On the 10-12th flight, the landing gear block came off. On inspecting noticed that there was not enough glue & that why the block came off.

Contacted NitoPlanes & sent pics. On speaking tp the rep after 3-4 days, finally convinced him that it was a manufacturing defect & he agreed to send out a replacement fuselage & tail group (as its glued into the fuse).

Got the replacement part in a week & assembled it.

On the maiden flight noticed some flutter in the elevator. Landed immediately & on inspection noticed that the stab wood had cracked on both sides of the elevator just where it attached the fuselage. I had used 30min epoxy & made sure NOT to cut into the wood while removing the covering etc

This issue definatly needs to be resolved if Nitro wants to remain in the market/business of selling model planes...
