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.

Тонкий и легкий медленный накопитель. Никаких непростых инструкций, так что вы должны взглянуть на картину перед тем, как собрать ее. Втулки должны быть хорошо выровнены, в противном случае вал имеет тенденцию зажиматься и работать с высоким трением. Мой комплект рисует 80mA на 4,0V (на 1 с липо) и показать некоторые вибрации - будет сбалансировать опору и посмотреть, то, если он тянет достаточно для моего крытый флаер...

Fine and lightweight slowflyer drive kit. No assy instructions supplied, so you should look at the picture well before you assemble it. Bushings must be aligned well, otherwise the shaft tends to clamp and run with high friction. My kit draws 80mA at 4.0V (at 1s lipo) and show some vibration - will balance the prop and see then if it pulls enough for my indoor flyer...

хороший маленький двигатель вы, однако, должны регулировать дроссельной отделки, чтобы иметь пусковой импульс в противном случае двигатель не работает , я поставил его на мини-Beechcraft от banggood

beau petit moteur vous devez cependant ajuster le trim des gaz pour avoir une impulsion de départ sinon le moteur ne tourne pas , je l ai mis sur un beechcraft mini de chez banggood

Он генерирует хорошую тягу с низким током. Но реквизит был полностью нарушен и породил сильные вибрации. Ты действительно должен сбалансировать это. Я планировал использовать его на моем 35-метровом планере, но он слишком большой и тяжелый. Мотор гонщика 8520 с 65-мм опорой KingKong является лучшим выбором - даже если ток намного выше для меньшей тяги.

It generates good thrust with low current. But the prop was totally out of balance and generated heavy vibrations. You really have to balance it. I planned to use it on my 35cm glider, but it is too big and heavy. The racerstar 8520 motor with the KingKong 65mm prop is the better choice - even if the current is much higher for a lower thrust.

nice product but motor shaft is very tigh t and motor casing is very tight too you have to make that bigger to fit
