Just crashed

I was out flying this weekend, after a long period with no flying. I finally got the time to spend a day at the field with some easy and nervous flying but it was a good day at the field, UNTIL.

It was the last flight this always happens on the last flight :) but this was the flight where I just had to use the rest of the gallon and on that flight, one of the tail blades was ripped off. And what happens when one of the tail blades and the grips is pulled off in flight ?

The tail will start swinging and at one point the tail will hit the main blades and what a crash, in 10 meters height the Frenzy 90 TT just self-destructed completely and fall to the ground in pieces. What a shame that I didn’t get that on video!

But here you can see some pictures, I didn’t feel like repairing the heli yet but I guess it is going to be expensive.

Final review of the Frenzy 90 TT

No Gravatar

Now i got the time and the flights to complete the review of the Frenzy 90 TT, the new and improved Frenzy.

To summarize the conclusion :
A good helicopter for the price, i don’t really understand the higher price on the TT version, but it is still a good priced model.

Yes that is it, it has some small issues, some of them you can fix with a hex and some you have to work a little harder to fix, but for the average pilot this helicopter is a great beginner and advanced helicopter. And please remember that you have to do small fixes with a high priced helicopter on the marked to.

But what i really like on the Frenzy is you can get easy access to the engine and clutch AND I LIKE THE PRICE.

This is a model most of you pilots would be very happy with, i am sure.

Just smack it around.

First Flight JS Frenzy 90 Torque Tube

No Gravatar

I was finally at the field today, there was snow but I can handle that and I was cold, that I could not handle, I was only there for 45 min.

I was able to get my new engine OS 91HZ-R started and my JS Frenzy 90 Torque Tube seems to be flying very well, I did do a short take off and there were no need for adjustment at all, very nice.

One of the reason why my stay only was 45 minutes. Was because my starter would not turn the engine! Yes my Dynatron starter had some problems starting the engine second time when I was cold, the Danish winter sucks. But there is a simple solution to that, run the starter on 24 volts, I just changed my setup and it works perfect, I am very happy with my Dynatron starter and the fact that it can run on 24 volts, a lot of power in that starter.

I will write a review when i have had some more flight time :)


JS Frenzy 90 TZ-V2, first test flight

You know the guy at your flying field there always seems to have problems and luck is not in his dictionary. I AM THAT GUY, with no luck :)

But i have learned to live with it :)

On the positive update, i got the Frenzy airborne and yes it flies nicely, here you can see below i made a small takeoff in my garden just to check the engine. The video is to boring this is just a screenshot of the video

That was a good start some days after i was heading to the flying field, well this day i would like to forget about this day, i flooded the engine resulting in the clutch coming loose, resulting in binding the clutch and no flight that day, as you can see from the pictures below, first day at the field bummer. But the Frenzy was easy to disassemble compared to the Freya.

Some days after i headed to the field again, a very windy day but hay no problem it a helicopter right. You can’t setup a gyro in hard wind but i could still get it up in the air, and i did it went well, i did some engine tuning and some gyro tuning, had some small tail wag but with some adjustment i was gone. While i am on the subject gyro setup let me show you a good link this is a QA from Spartan, very good information http://www.spartan-rc.com/support.php

But then the problem started, suddenly in a low upright flight the helicopter just started spinning very fast it is my luck that i am practicing piro maneuvers with the throttle hold i manage to land the helicopter without a scratch.

With some post flight inspection i discovered that the tail was stating to some off or the axis on the tail was. A lesson to all of you when you get a preassembled model check every screw on the model, i apparently missed two at the tail. As you can see from the pictures the two screws holding the tail axis was not placed correctly resulting in the tail sliding to one side and the helicopter doing aggressive piros.

JS Frenzy 90 TZ-V2, finished

The final day of building the Frenzy 90 and i must say that i am impressed, it seem like it is good quality and my overall impression of the build is good, i had to do some minor adjustments but nothing a Dremel can’t handle. 5 night to do a complete build and setup.

I got +-11 degree pitch.

I will do a complete review when i have had the change to fly it.

Here are some of the modifications i had to make.

I rounded the corners at the base of my SAB blades, the corners was prevent the blades to be folded back for transportation. And i added some shims tog get a better fit of the blades, see pictures. And i have tried to fit the antenna.

For the rest of the pictures go here.

Check out the nice antenna solution i have made, i hope it lasts.
