This review is from: Double Horse DH9116 Infrared Gyro 1st Single Blade 15" Large RC Helicopter 4 CHANNEL Great chopper. Very fast, once you trim it up properly this has excellent control. I have 3 spare batteries but usually give it a couple minutes to cool off, but runs like a champ, till you crash it. Spare parts reasonable, easy to change out and repair. I had 4 of these over about 3 years, what is broke off one, trade to another. Help other customers find the most helpful reviews  Was this review helpful to you? , September 21, 2016

    It's not tough enough.

    Training gear is for people just learning to fly RC helicopters. It's expected for beginner's to land hard, especially when you get nervous and slam the throttle/pitch down when losing control. The plastic hub will break with a mild landing. I didn't crash nor did I have a hard landing. The heli came down at a slight angle and two of the balls made contact with the ground first and the hub broke. I made my own training gear using a piece of 2" x 2" x 5/8" piece of hardwood for the hub and 5/16" dowels for the rods. I reused the balls that came in this kit. I quickly ran a 5/16 drill through the balls and they fitted securely on the ends of the dowels. It works great and I've since had some extremely hard landings, but the wooden training gear doesn't break. I paid just over $3.00 for this gear, so in my opinion, the balls are worth it. It beats having to buy plastic balls and drilling/mounting them to the ends of the dowels. That's why I give it 3 stars... 3/5 Mark M - See all my reviews Verified Purchase(What's this?)

    Works ok, but could use a tweak.

    3/5 Vicki Spicer - See all my reviews Verified Purchase(What's this?) This review is from: US Ship Rc Helicopter Training Gear for Trex 450 and Clone, Blade 400, 450 Helis I purchased this for my wife who has flown her F45 only once and broke the landing gear. I like the fact that it cushions the landing and also helps to stabilize the heli so that she can learn to control it better as well as helps with landing practice. There are three recommendations that I would ask the manufacturer to implement: 1) some instructions would be nice as it took me a few tries to attach this to the heli, 2) longer zip-ties as the ones that came with it are about the smallest you can get, and 3) the center hub is made of really thin plastic. These need to be made of something that can withstand the intended use. Both the plastic center hubs have broken on the same day and the product is now useless until I can fab something up to replace it. Other than that the procut seems to be ok. I would give 5 stars if the manufacturer follows these recommendations, but until then only 3. Help other customers find the most helpful reviews  Was this review helpful to you? , February 1, 2014

    worth the price

    4/5 Andrew - See all my reviews Verified Purchase(What's this?) This review is from: US Ship Rc Helicopter Training Gear for Trex 450 and Clone, Blade 400, 450 Helis A necessity for any first-timer. Other reviews say the center piece breaks, but for $7 the balls and bars are worth it. Make your own center piece out of wood or something. Haven't broken mine yet. the kit comes with 2 center pieces.I have to say, these training wheels are very necessary. I never knew how difficult it is to fly a 450 size copter (first-timer here). It's like trying to fly a large blender without any protection. I cut my hand with the main rotor the first day, and I'm a careful person. Any kind of assistance is very much needed if you don't know what you are doing. It is very fun though!

    Crazy Fun!! Need alot of open space.

    5/5 The Walsh's (California) - See all my reviews Verified Purchase(What's this?) This was my first helicopter and I read the reviews and ordered a smaller one to practice with.Everything is fairly straight forward; it has to be as there are no usable instructions for assembly.It comes almost fully assembled and only requires attaching the tail rotor boom to the main body (10 small screws)The only minor hitch I had was getting the plastic front bubble off so I could attach the two connectors.It had small rubber friction holders on the side that just pulled out, but this wasn't obvious (to me anyway).Once assembled it flew slightly backwards (someone suggested adding weight to the nose) and took a while to adjust the trims and get a hang of the controls.I would recommend attaching a thick string (if you're a newbie) so it doesn't get away from you until you are reasonably competent.Also above grass if possible.

    DONT BUY THIS

    1/5 Kevin Sardinha - See all my reviews Verified Purchase(What's this?) After you receive it you will go through the manual and do everything step by step and when you test it out in doors (large warehouse pace) it will not lift and if it does lift 3 inches the blades will either hit each other and damage or hit the floor and damage. You will issue an RMA and seller will say it is not in factory condition (OF COURSE AFTER ALL THIS) and it will be lost for ever with no refund or broken product (because you wont receive it back) Help other customers find the most helpful reviews  Was this review helpful to you? , March 19, 2013
