Made up a mount for the throttle servo, I prefer short direct linkage rather than long snake to middle of plane for throttle. Bit of ply and some hardwood bearers, epoxy in place.

Used Dubro 2-56 Ball Links for 4-40 rod to give solid slop free throttle linkage.

If you want a reliable repeatable consistant idle and throttle response, use a good accurate servo for the throttle, not some old sloppy gear train spare.

Using Futaba Digital here.

Also had a customer that has one of these tell me to get everything up front, as lead will need to be added to get CG right so mounting this up front will help a bit with the cause too!

Used the supplied battery tray (if you go electric) as a removable fuel tank tray etc. Cut the centre away to make room for the tank. Worked out a treat!

Replaced the stock tank (huge! for glow I guess) with a dubro 16oz, moved rearwood to sit on CG instead of right up front.

Dubro Fuel Bung, Dube 1/8 Fuel Barbs, Tygon Fuel tube and walbro filter clunk inside tank.

Replaced tank cap with Alloy Billet PSP tank cap.

Set up with 3 lines - Carb, Fill (bent to point toward front of tank, and vent to top of tank) all secured with stainess steel tie wire. Makes a good leak free setup.

But of a job to get it all in the tank through the neck, but can be done (rotate the pipe around by the brass tube after inserting into tank to get the right angle for vent line etc)

Final install of engine, Blue loctite on all bolts, with washers and spring washers.

Length of 2-56 Rod with threaded end, to nylon clevis, bent to shape for manual choke, accessible through front of cowl (inlet)

Ended up trimming about 20mm off the end of the muffler outlets so the cowl is easier to fit (newer DLE-35RA muffler are already shortened, and come with teflon extensions) with fit telfon or silicon extensions onto muffler after cowl is installed.

Stock muffler otherwise fits in nice and neat tucked behind head.

While I was at it, fitted the plug,a nd set the plug gap using standard #11 xtacto hobby blade - happens to be just the right plug gap setting

Mounted fuel dot up high, inbetween front cabanes. Looks scalish, and above fuel tank so fuel doesnt drain out as soon as you unplug the dot

Busy weekend - got the ok from the boss to spend the day in the shed kid free to get it finished off

Mounted ignition under engine box, behind muffler. Dont think heat will be a problem, but just in case bent up a heat shield out of some thin aluminium and screwed to bottom of engine box, couple bends at the edge.

Wrapped the plug lead with the wrap (supplied with the DL/RCEL ingition) to protect the lead from chaffing/rubbing. Looped and cabled tied plug lead in neat behind the shield.

45 Angle on the plug from the head keeps everything tucked away nice.

Ran the servo leads for the ailerons, up the cabanes. Sheathed in red expanding type nylon braid to protect and make look the part. Tidied up the loose ends with some heat shrink.

500mm Twisted extensions where just long enough to reach the RX where I decided to mount it.

Didnt have red cables ties, so used white ones and coloured them in with a red "sharpie" marker to blend them in a bit

Mounted RX using thick stick on velcro and neaten up servo leads under tray.

Cut a few short lengths of tube from RC Car Antenna tube to support the antenna's at 90 deg to each other. But of scotch tape over the tips to stop them vibrating around and possibly failing.

Installed Tech Aero ingition batt elimator and kill switch (top left)

Will be running dual batts, with batt share for power. This will supply servos/rx and ignition power all from the same source. Mounted LED for IBEC ont he same side in one of the already laser cut holes they provide from graupner power switch option. Nice fit in black pin stripe keeps it neat.

No pic of that though yet.

Got the dremel out and fitted the cowl. Lots of test fit and mark and grind and test fit and mark and grind. Part of the scoop on the bottom of the cowl has to go for the head to stick through.

Otherwise fits quite well. Lots of air out from the very large "cheeks" on each side, so I dont think air out will need to be cut out of bottom of cowl that would normally be required.

For a change I decided was time to get the wings sorted, Mounted up the 16kg ScannerRC servos (9900HV titanium gear jobs we get made for us by ScannerRC in Taiwan with imported Japanese coreless motors)

1" MPI futaba allow arms.

500mm HD twisted servo xtns, and heatshrink over the connections so they can come loose inside the wing.

Replaced stock screws with cap head self tappers for servo mounting and hatches

Glued (used 15 min epoxy)in the cabane fixings, and epoxy aileron control horn. This differs from the supplied instructions that show different attachements that are threaded into the wing - They have changed this for the current crop out of the factory but not updated the manual yet. The servo horn also has two slots but only one epoxy horn supplied - so picked the slot that lined up best with the servo arm and push rod. Double setup would be nice, but dont think really neccessary on this model.


Dubro 4-40 ball links with the supplied Clevis's and push rod.

Mounted main power switch (only switch on the model as using IBEC)

Brico failsafe pin flag switch, soldered on deans style connectors and the Deans-Dual JR adaptor into RX, one JR lead into batt port on RX and other into spare channel for more overall current available to RX/Servos.

Nice bright green LED you cant miss when ON!

Glued the pilot in place, and windscreen using plumbers roof/gutter Silicon, and couldnt help but throw the wings on to make it look like a plane while as was at it

Found out wing tube was very very very very tight - polished/sanded the tube with water and 180 grit wetndry paper, followed by 600. About 45 mins later the tube will now fit..just (with the help of some silicon spray)

Mounted the cabanes, little bit fiddly, rear one needs the ball link wound all the way in so had to trim about 4mm off the threaded rod, front one worked out OK. I wicked some thin CA into the wood ends/rod to lock everything in one sorted.

I replaced the supplied plain nuts, with 3mm locknuts (nylocs)

Bottom attachment above landing gear needed bending up at about a 45 deg angle.

Fitted cowl spinner etc, to do quick CG check. Way tail heavy! Batteries need to go as far forward as possible. I have upped to battery size from 1400 to 2300 A123 packsnto help with some forward weight. Better more battery than lead.

Cowl cheeks leave lots of room to mount them (lucky) so strapped one to each side, using stick on heavy duty velcro and big cable ties. One bonus is will be able to access charge leads through the outlets of the cowl cheeks, so less holes to cut in plane for charge points.

The two packs are connected to 42% HD 2 Pac battery share, then back to switch. Enough power here for a 40% model!, But still going to need lead to balance.

MiracleRC alloy spinner and Falcon carbon Fibre 19x8 Prop is what Im going to start with. These will pull just under 8000rpm with the 35RA and should give good balance of speed/thrust. Factory vid shows 18x10 with OS engine.

Spinner looks bling compared to crappy stock platstic one that comes in kit.
