The Beastie is Best Boys……

[Lad]

It was the maiden of my new Trex-700n a week ago with the BeastX on board; my first venture into FBL and not sure what to expect having read all the horror stories of ‘tip-overs’ on take off and ‘elevator bounce’ etc.

Well the first flight was interesting; pretty much stock setting on the BeastX resulted in an autonomous aileron roll over to left on the far side of the field ……that was exciting to say the least! After a short investigation it turns out I had a vibration at a particular head speed that seemed to agitate the BeastX.

Well today was a ‘working from home’ day, the sun was shining and as I started really early 1st thing this morning (honest), I decided to sneak off to the field for an hour to do some tweaking.

Roll forward a couple of flights….. BeastX now strapped down very very tightly, the response set to ‘extreme’ the all the tail adjustment made….

Bloody-hell this thing rocks! I simply cannot believe how well this fly’s ‘locked-in’ and ‘hyper-power’ are understatements (and I have a FB Trex-700n for comparison). It’s a bit like driving a Ferrari having owned a Ford all your life…………

Anyway, the bits to convert the Trex-600n should arrive tomorrow ~ happy days…….

Take a read of some of my early posts on the BeastX.

Almost word for word what you have written.

The main issue was the stock pad under the unit, ditch that and hold it down with some Maplins double sided 1mm tape secured with a velcro strap.

Unit set to "Extreme" and that thing whistled..

What did you find as the cause of the vibration Lad. My 700 done the same found the clutch had broke.?? So I dont use the standard pad.?? And strap it down.??

No obvious source of vibration, nothing broken or massively unbalanced ~ it just appears that at a certain head-speed a resonance makes it’s way through to the BeastX. If I turn the governor off and fly on curves I can fly through the resonance point.

Strapping down the BeastX has completely masked its sensitivity to the resonance point and it fly great.

Final thing worth saying is the engine (YS91) is new and currently running very rich ~ I suspect over time as I lean it out the vibs will reduce significantly
