Yes! finally

I have finally got my Frenzy rebuild after last crash. As you can see it is a very long time ago the last crash, long story short i had to wait for parts and i did have some motivation issues, but now i am back in the game, just need to make some governor setup and some weather over -10 degrees.

The reason for the crash, i found the my old tail blades was at 8 grams and the tail blade holder was not made for 8 grams tail blades, apparently. Not the best design my Frenzy TT, but if you don’t use 8 grams tailblades you will be just fine.

And some nice new pictures

Final review of the TZ-V2 Frenzy 90

Now i finally got the review of the new Frenzy don, please have a look for an in-depth review of this great model. http://rcheli.dk/frenzy-90/

As you properly can remember from some of my previous post, i have had some problems with my engine running warm, but you can solved that problem, just by changing all the fuel tubs on the Frenzy, specially the tubs in the thanks was very thin and seemed to be a big problem for my engine. But the model is flying great now.

My starter engine finally died on my and i have to get a new one, i have concidering getting the Align but word is that the Align super starter (ASS) is not perfect for a 90 size engine and that is why i am getting a Dynatron 120 starter

First flight with JS Frenzy 90 TZ-V2

I was at the field today and finally the flight went as planed, i had some engine tuning issues last time, but with a reset of the needles that problem was slowed, i set the needles at 2 turns out, both needles.

And the the flight was on, my Idl 1 is set to 1550 Rpm and my Idl 2 i set to 1750 Rpm, i was manly flying in Idl 1 today, it is amazing what stuns you can pull with 1550 Rpm’s on the head, tic-toc i no problem. The model was flying perfect, i still need to fine tune my gyro, i have slow tail wage when i do fast pitch input, the Spartan Gyro is working great and i esspecialy like the fact that the piro-rate is constant and the tail is rock-solid.

This is a mix of two small videos i have made, with the camera laying on a table, there was no others then me at the field today :( sorry.

Scroll down to see some more pictures of the new canopy, the colors are great i can easily see the model in the air.

Okay first flight

Made it to the flying field today, great. It was cold and windy but the Frenzy was airborne and got 3 flight don. After the first full tank i re-tighten the tail belt it was a little lose, perfectly normal after first flight with a new helicopter.
I did run into another problem with the heli, it was not related to the Frenzy but the engine.
When i was flying IDL2 and did some fast flying the engine started to get very hot and started to lean out, but it is properly because i had set my governor a little to high in IDL2.

I have been concidering for some time if i should get the Align Super Starter, as you can see but i have not been 100% sure that it was a good starter for a 91 engine in the cold winters here in Denmark.

I then decided to fix my old starter, the new Frenzy has a one-bearing in the starter shaft that was great new, because my old starter wand one-way was broke. I mounted a new starter wand and two lipos on the side resulting in great power for the starter engine.
In combination with my new glow plug starter i can walk to the flight line and start my engine and not in the pilot area with my starter box. See pictures with my new starter and my glow plug starter with a meter on.

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.
