The Build


Inside the one of the 3 boxes. Well thoughtout and packed to ensure no damage during transit.

The contents of the above box. Each item is bagged up and foam wraped in places.


The fuselage unwrapped. The finish is top class and the canopy/hatch is well formed and lightweight.

Fuel tank per installed & plumbed. You can also see the lightweight yet robust construction.

The motorbox & firewall is very strong and pre-drilled to accept a DA100 or DA120

MTW TD75 Cans installed, the mountings were already in place, making this installation painless.

DA120 mounted with Cans in place.

You can see the block standoff’s as supplied in the kit. All side thrust is already built in to the required amount


H9 wheel axle. We have found these to be strong & hardwearing over many landings, even on rougher runways


Powerbox SparkSwitch was used on the iginition. This unit is small & neat. It is powered via a standard 2s Lipo, the signal is controlled via a spare channel on the RX. There is a bright LED which is fitted to the Outside of the model. Powering on/off with this unit has two options, the simple on/off via switch on your TX or the preferred method known as Safe Mode. This requires you to Arm/Disarm the system by moving a switch on the TX to one position and then back, that arms the igntion and the LED shows, the same process is required to Disarm the ignition, a two flick method. You won’t accidently switch your ignition of in flight.

Upclose

The complete igntion system, very simply. I’d highly recommend it and will be using this system from now on.

We added a intake baffle to our cowl. This will keep the DA as cool as it can be in flight, especially during hard freestyle flights.

Baffles from inside. Light ply & a light bandage

Inside the fuselage, you can see plenty of space

ts

Our RX is the new Spektrum/Powerbox AR12200 Cockpit. It features onboard battery usage info (Mah used, Amp draw & voltage), as well as RX performance for each of the four sats. You can also servo match to servos on 4 separate channels and if required there is a Door Sequencer for your scale projects.

RX Batteries up front, two Spektrum 2s2p 4000mah Lipos.

Powerbox MPX servo wire connections. This is more reliable than the standard JR style plug, over time these can become weak & fail

Elevator & Rudder servos, spektrum A6030 & H9 servo arms.

Flying Shots

 

 

 








These pics were all shot on the 1st & 2nd flights, so you can see I was very comfortable straight away. This is best 35% aeroplane I’ve ever flown, it feels as agressive as my old favourite the 33& Sukhoi and equal precision as my 40% IMAC machines. The DA120 gives true unlimted vertical and the spektrum A6030’s are perfect for this model.

I hope to get a video very soon.

Thanks to Mike McConville & Horizon Hobby UK for this superb plane.
