I have 2 Intrepids. I have yet to find a nicer flying heli. The only gripes that could be found is they might not have enough cyclic response for some people, and the spares are quite expensive - although that's mainly 'cos the parts are all nicely machined metal and well designed.

Has anyone seen the new Diamond range of helis that are due out soon. I believe the 90 version is due to be launched at Charmouth in October. It seems to be a design which uses the best ideas from all helis to date. This includes a very similar head to the aurora, and gorgeous tail gearbox, complete with double pivot tail pitch slider. Apparently it is planned that there will be 60, 90, gas, electric and turbine versions, and the turbine version has a properly thought out place for all the anciliaries, and no silly saddle tanks!

I found this the other day, as it's being designed and manufactured by the guys that do the Bergen spares in the UK;

www.bergenhelicopters.com

Apparently, the intention is to create a heli that needs no upgrades, incorporates the best of the modern model heli features, and the aim is to retail at around £1000. Is there any heli this side of the £1700 Eagle EX, or £1300 Sulphide 90 that has this level of quality and features (it looks better than the Eagle, as far as I can see)?

This is one model that I'm going to be keeping an eye on! What do you guys think?

 Hehe. No, unfortunately I'm not anything to do with it. I rang up a few weeks ago, for the first time, to order some parts for my Intrepid. I ended up talking to the guy for a while about it, as I'd seen the pictures on the website. I hadn't noticed any discussion on here about it, so I thought I'd start off the topic.

This being my first post is due to the fact that I'm just getting back into RC helis after a long gap, and I've just discovered this website - Runryder didn't exist when I last was flying regularly!

That looks like one nice machine! I want to see more. I will have to keep an eye on the progress. I am in the market for a 60.

Diamond 90? thats a similar name to the diamont 90. Looks alright but that is an upgraded predator.

Think it's a little unfair to call it a Predator upgrade. Granted it uses a Predator main gear (for now) and a Bergen fan shroud (for now) but other than that it is a clean sheet design. 4CCPM control, 4-5mm compound flybar system, hibrid sintered bearing technology and no plastic. We have looked at the common weaknesses of other helis and tried to design them out whilst looking different.

I did not intend to put your heli down all i meant was that it does have the layout like the predator but with all the whistles and bells

The collective arm and bell cranks are cast(not CNC'd) out of what seems to be puter, I used to bend them in flight and forget about crashes, they tweaked all up. Ok flying helis, but don't crash em' cause it'll never fly the same as before.

No castings on the heli. All parts are machined from billet alloy 6082 T6 for maximum strength. Photos of finished frames should be posted next week once assembled and checked. The elevator yoke system is coming of the cnc miller tomorrow. Did consider investment cast aluminium originally but dropped it on performance considerations.

Nice looking heli, but I prefer the new high-cg design philosophy of the Aurora and N9. Also, I suspect that those CNC machined parts would be very expensive to replace when twisted.

The heli has been designed so that the c of g is around the centre line of the tail boom, this way we should have a benign roll characteristic.

We would hope parts prices will be as competitive as the competition. However is must be said that all the helicopter is produced in England and not some prison camp in the far east. Engineers in the UK expect to get paid a fair price and go home in the evening.
I have just returned from 2 weeks in China at a manufacturing plant (commissioning work not sourcing parts) and the workers had to do 14 hour days, sleep on site and got 1 day off per month. Not ethical in my book.
Also we have deliberately designed weak points into the model so that when it gets pranged, a relatively cheap minor component will give way to try to save the more expensive parts.

4CCPM control


I'm assuming that this refers to having 4 servos used for CCPM. I was under the impression that a 4 CCPM set-up, though in theory sounds better than 3, is actually less desirable due to the fact the opposing servos can bind and fight one another in many instances.

What are your ideas on this? James Wang is a pretty well respected authority on Heli control systems both full scale and models. He warns against using a 4 servo CCPM set-up.

Yes you are right, 4 servos for cyclic and collective control. It has been a tough nut to crack, but we prototyped this system on a Century Predator turbine conversion (see turbine gallery for Multicom). We have managed to acheive ±12° with no interaction on any servo. I realise that many people will not like this system, and would prefer other control types and with this in mind, a 3CCPM version will be available at 120°. We would not offer the system if we were not confident in it working, especially when using digital servos, because interaction with these leads to damage and flat batteries very quickly.
Our goal is to offer a top quality, reliable product, but we know we will never be all things to all men. As they say in Poland, 3 men in a bar discussing politics would come up with 4 new political parties!!

Unfortunately it doesn't work quite as simply as that..all that you can do/have done? is raise the centre of gravity closer to the rotors in a similiar fashion to the 'Synergy'

A helicopter rolls around the rotors not the boom. Therefore the height between the rotors and the horozontal CofG is what is important
