Laservampire Posted June 17, 2013 Posted June 17, 2013 Just got one of these from my girlfriend for an anniversary present (best. girlfriend. ever.) I hadn't looked at the set before but after reading the review I can't wait to build it! Quote

I hadn't looked at the set before but after reading the review I can't wait to build it! My girlfriend got me one for Christmas. I bought a second and third copy after building the first. Great set!! Enjoy! Quote
technicgear Posted June 18, 2013 Posted June 18, 2013 Nice review. I am considering this model as my next acquisition... or perhaps I wait a few months and get the new mobile crane. Not sure about it... Quote
SheepEater Posted October 26, 2013 Posted October 26, 2013 (edited) Hi! I think the 9396 is great set, built both models, and yeah, pleased with it... but I remembered just now that the B Model is not the first lego helicopter with Intermeshing rotors! meet the B Model of the otherwise crappy 8444 Edited October 26, 2013 by SheepEater Quote
Aurock Posted January 1, 2014 Posted January 1, 2014 My son and I finished building this one last night. We're having some difficulty with driving the main rotor. The gear on the ratchet piece seems to be getting bound up, pushing it to a bit of an angle and then it starts skipping. The rachet works perfectly when turning the drive the other direction, lifting the gear up out of the way. Has anyone else had this binding? I can't see what we might have done wrong... Quote
cwdyang Posted January 7, 2014 Posted January 7, 2014 (edited) Here's my modified version, yet to be motorised. Edited January 8, 2014 by cwdyang Quote

The ratchet is intended to do this. It shall drive the rotor only in one direction. In the opposite direction it will start "skipping", it basically acts as a simple clutch. The purpose is to protect the gearing when using a motor. The motor (e.g. 5292) can spin the blades quite fast, giving them a high momentum and as Newton's Laws of Motion postulate, an object wants to stay in its state, the blades will continue to rotate even if the motor is switched of. Having a static connection to the motor would hurt the gears and axles very much. Gerald Edited January 7, 2014 by freakwave Quote
