Mine was broken for both the 1st and 2nd piece of the belt. QC issue, hope HK can improve. But the hard fact was that my beloved HK-250GT was destroyed because of this problem, dropped from the sky like a expensive stone dropped from the sky :(
But anyway, always inspect all the parts (inclusive of Belt) everything you want to fly. Look out for strange sound for any wear-tear problem. Just like a real pilot :)
* JoeHeli: Yes, the replacement still broke. I'm now rebuilding my 250-GT with placement parts but perhaps this time I will do a thorough check before and after flight. Anyway the belt is still cheap, but a few more for backup. Must have some "Tender, Loving, Care". Cheers!
The tail belt that comes with the HK-250GT is total garbage and I don't imagine the replacements fair much better.Unless you like playing Russian roulette with your investment,replace the stock belt with one that is better quality.If you do a Google search for "Super tail belt for T-REX 250",you will find what you are looking for.It is a kevlar reinforced belt that really holds up well and will give 10 fold better performance and service than the stock belts currently being supplied.I hope this helps steer someone in the right direction to success as opposed to frustration and disappointment.Cheers!
mine, which came with the helicopter is working fine... i crashed my heli 3 times .. lost 2 feathering shaft and the stablizing bar but the timing belt z fine.... gonna order this as spare part... lets see .....
