Hi heli people.

Ok, I'm looking for a new project and would like to get my hands on a Hirobo EC120B. It looks like they are very hard to find as Hirobo is a dying breed in the scale. world I found one for sale in Singapore, but they have doubled in price from $3300 Singapore dollars to now $7742. Are they a collectors item now? $7742 is a little crazy for a 60-90 size heli. If Hirobo are not making scale fuselage then they may not need the EC120B mold/plug anymore.

Any info would be great thanks.

Cheers

Well, after many years of toying around with having a MD500e with a 5 bladed head, the up's and downs of freight damage of my MD500 from Hong Kong( thanks to James Kong from jet tech for sorting that out great service) Shit blades from spinblades etc, the fleet is now complete with the new addition. NO more toys for me, I just want to fly now.
300KV from EgoDrift
680mm Witte blades
Funkey 700 size with Roban struts modified to get the correct MD500e stance.

Spinblades review.

Well, Where do I start?
I don't like doing this, but I don't want others to go down the same road I did, but if you do, this could happen to you.

On the 20th September 2022, I purchased a 5 blade set of Spin blades for my 60-90 Size MD500E from Germany. After looking around for a very long time at different options, and what is available on today's market, the main thing I was looking for was a scale look.

The Spinblades did it for me because they are 40mm wide blade, long and skinny like a true MD500E. I got them to cut them down to 680mm for an extra 50Euro's, I asked if they could also paint them. They advise, yes not problem for another 50 Euro. As this saves me doing it. As we all know that a 5 blades set is busy in regards to CG, Weight, and then you need to track them etc.

I was told approximately 4 weeks to have them completed and I paid DHL world express to get them fast as it was coming up to Christmas. After 6-7 week I sent Spinblades a message on What'sApp and they said yes, all going well, the blades are in the proceed of being painted and will send them out soon. I replied, Thanks sounds good. Then 3 month later I got my blades and from the photo's below you can see the lack of quality and workmanship of the Spinblades.

In summary the blades are S**t and as you can see and Spinblades won't give me my money back because they are custom built blades, ( all their blades are custom built ) They said, send them back to us at your cost and we will look at them and IF they need to be fixed we will do it, and then we will send them back to you, and you will need to pay shipping again.

I am very disappointed with the quality of these blades and they lack of service.

WT :blowup:

Sorry what?
To be honest, I dont want to send them back because what the hell am I going to get the second time around, if this is what I get as a first time customer. NOT A GOOD LOOK. The blades with shipping cost me $445USD. SO VERY DISSAPOINTING SERVICE SPINBLADES.

OK heli guys, so the next step for my MD500E 700 size is putting on a set of 5 blades and head. So I've got the Roban head and now looking at the blades.
The only 2 brands that I'm looking at are the Spin Blades that are Asymmetrical and a good price. The other is the Witte blades that are full symmetrical and more expensive. So we all know the difference between the two blades and both have pro's and con's.

The problem that I have is the gearing on my T-rex700N of 8.2:1. In Scale heli's it's all about LOW headspeed, say around 1300-1400rpm give or take. I was flying the X45H in Gov mode at 1900rpm ( with flybar ) and found the headspeed was always going up and down so I changed it to throttle curve and haven't had that problem anymore.

So the heli will be around 8-9Kg with the 5 blades on and full of fuel. So my question is, has anyone used 5 blades on an X45H yet? if so what blades? Will the motor overheat if I lower my throttle curve to get a lower headspeed? The black blades are Witte at 680mm long and 160g each blade the others are the Spin blades at 700mm at 125g each blade. Thanks for any help, Happy flying.
