I took a chance on this, because I didn't think there was enough information in the description. I ordered the C version, with the 8x20mm motor, but unfortunately what arrived today was the A version, with 7x16mm motor, so the figures below are for the A version. I haven't powered it up yet, but I think it will be very suitable for an indoor slow flyer of the Vapor, Ember, Cub etc. style. With the 8x20mm motor probably something a bit bigger and/or faster. The prop has a diameter of 138mm, but no pitch marked. By comparing it with other props of known pitch I am guessing it is a 138x63 mm or 5425 inches. It came badly out of balance, but by taking tiny shavings off the heavy blade with a modelling knife, I eventually got it to balance perfectly. It is very light at 1.24g, and I don't think it would withstand a hard impact, but ideal for a slow flyer. The description says it has a .8mm hole, but when I measured the prop shaft, it is 1mm diameter. I tried pushing it into the prop and it is a very tight fit, but does go in. The gearbox is the usual two brass bush type, with plastic 9 tooth pinion and gear. I didn't count the teeth on the gear, but I'm guessing there are 54 giving a 6:1 ratio. The prop shaft is 27mm long with one end knurled for a length of about 8mm. I think the knurled end goes into the plastic nut provided, with the smooth end going into the prop, so you can remove and replace a prop without much trouble. Weight of the gearbox is 1.29g and of the motor 2.61g. Motor shaft is 1mm diameter. There is a square hole in the gearbox that I think is intended for mounting on the end of a square section carbon fibre rod, such as you might use for the fuselage of a very light slow flyer of the Vapor type. It looks as though it is a 2x2mm hole. It would probably be possible to mount the motor/gearbox other ways, e.g. with tiny cable ties or with glue. The proof will be in how it runs, but at this stage I think it's a very light and economical power plant for an indoor flyer, with flexibility in the choice of motor according to your intended use.
Great micro motor for ultra light aircraft under 4 ounces. It ships unassembled but assembly is easy. The propeller balance should be checked and corrected before use. The gear is a little noisy at low rpm but it smooths out at flying speed. I used one in a Guillow's Lancer airplane I converted from rubber power to electric motor and 3 channel RC. This motor and propeller provide more than enough thrust for this under 50 gram airplane.
Nice Motor....... Enough Thrust power to my DIY plane.....
pequeno motor bonito você no entanto tem que ajustar o corte do acelerador para ter um impulso de arranque, caso contrário o motor não funciona, eu o coloquei em uma mini beechcraft de banggood
Entrega rápida, condições perfeitas, mal posso esperar para começar a construir
Kit de unidade de folheto lento fino e leve. Não foram fornecidas instruções de assistência, por isso deve olhar bem para a imagem antes de montá-la. As buchas devem estar bem alinhadas, caso contrário o eixo tende a prender e a correr com alta fricção. O meu kit tira 80mA a 4.0V (na lipoaspiração de 1 s) e mostra alguma vibração - equilibrará a hélice e verá se puxa o suficiente para o meu panfleto interior...
this item is very good has super power i use for mini cessna airplain fly very good https://www.youtube.com/watch?v=sOhNC9UEu_U&feature=youtu.be
Ele gera um bom impulso com baixa corrente. Mas o adereço estava totalmente desequilibrado e gerou vibrações pesadas. Você realmente tem que equilibrá-lo. Planeei usá-lo no meu planador de 35cm, mas é muito grande e pesado. O motor de corrida 8520 com a hélice KingKong de 65 mm é a melhor escolha - mesmo que a corrente seja muito maior para um impulso menor.
nice product but motor shaft is very tigh t and motor casing is very tight too you have to make that bigger to fit
Works perfectly fine for small indoor models.
