Hooked a thermal on the second motor run.
Motor is over propped, but required altitude is reached with short motor runs so it doesn't get too toasty and has plenty of time to cool between runs.

First flight was successful. (Fast and stable and rolls like a drill bit.)
Damaged the nose (15mins to fix) on the second launch. ( Needs to be launched like a funjet! )
I might shorten the nose a bit while I'm repairing the damage.

Plan is to build something strong, but easy to maintain/repair if damaged, that will support multiple wing/fuselage/empennage combinations

Two bolts to remove tailplane.
Two bolts to remove gear.
Wing mount will be setup for two bolt attachment/removal.

I'm thinking about a clip arrangement so a profile fuse can be installed/removed in one or two pieces. ( RC car canopy style?)

1 allen key and 1 spanner should disassemble the majority of the airframe.
Majority of bolts will be 4mm hex heads with nylock nuts.

Fuse is 19mm X 19mm , 1.2mm aluminium box.
Fuse length : 1000mm
Horizontal stab width : 520mm
Vertical stab height : 200mm
Engine mounts 12mm X 12MM , 1.5mm aluminium channel with hardwood inserts.
OS 55 AX with a 13X4 APC prop.

Wing/wing mounts next...

I smoked the Turnigy Typhoon 450H 2218H outrunner on my #2 boat so I replaced it with a Turningy 2836 3700kv Heli outrunner. Running on 3S it's a screamer and makes the hornet fly. ( Literally on a couple of occasions!! )

It's over propped and over fed so it's getting pretty toasty. ( I've only been doing one or two full throttle passes then bringing it in and running it unloaded to cool down.)

I thought I'd try a "direct" cooling approach. I wanted to keep the cooling water from spinning off back into the hull, so I put the outboard cover back on. ( It's also holding the 'spray' hose in place.) I've 'wiffled' the back, sides, top and bottom of the cover to let cool air in and hot air and water out.

I've got alloy legs coming for both my Hornets, so it's only a temporary solution until they arrive.

I let the magic smoke out of the stock motor on boat #1 so it was replaced with a Turnigy 2836 2350kv outrunner.
The stock motor on boat #2 never saw current and has been swapped out for a Turnigy Typhoon 450H 2218H outrunner.

I'm just playing with motors I had in my spares box, and they're more than likely operating outside their intended current ratings. It's all fun and games until the magic smoke comes out. ( Then it's still fun and games, but components need to be replaced.)

I'm intending on replacing both outboard legs with more 'substantial' items.
Then it's on to upgrading motors and ESCs...
