Dear all,

I have an option on a T-hangar which needs the plane to be moved uphill, tail first, into a narrow space (8 inch clearance each side of the HS). Doing this alone by hand with a Bogi-Bar ...

Hi all, I am just in the last stages of ground testing before first flight. I have a new IO-540 from Vans and have run it somewhere between 1 and 2 hours for run-ups and taxi tests.
After each engine ...

Like a number of earlier posters I'm not having immediate success finding opportunities for transition training on the RV-10.
This is not an insurance requirement but a strong personal wish, and tho ...

Has anyone else out there noted that the single washer specified for each of the NAS wing attach bolts (page 44-11 figure 1) is not sufficient to prevent the nut binding up on the bolt thread runout b ...

Are you increasing engine rpm above idle during the checks? Some alternators/ pulley size combinations will not get above battery voltage until the engine speed is higher.

Good luck and happy holid ...

Hi Les, Kelly, it has been suggested that using foam under the front floor pans can help reduce external noise caused by exhaust resonating on the underside of the fuselage. I bet no-one has done a b ...

Carlos,

I glued the door halves together the first time with Cab-o-Sil.

I got nervous about the cracking noises when I tried to flex the doors, so I peeled them apart again by hand (very easy) a ...

Dan,

The good fuel flow readings from your test with the electric pump are a nice health check for the boost pump but do not necessarily prove that system upstream of the mechanical pump is good. ...

Hi all,

I am trying to hook up audio outputs from a Garrecht TRX-1500 (3Vpp, 8 Ohm) and Dynon Skyview (10V, 50 Ohm, output volume controllable by software setting) into a PMA5000EX (510 Ohm, max 3V ...

Hi all,

Does anyone have experience using the Aircraft Spruce teflon lined A-920 cables with CableSafe2 or similar fittings at each end (quadrant installation) instead of the Van's or ACS A-1550 throttle cabl ...

Carl, Jesse, thanks a lot for challenging me to go look again. Now I managed to find the hardware and gasket. Definitely time for some 5S in the workshop….

Cheers,

Gordon

I have the Van's Lycoming IO-540 and am ready to attach the fuel servo to the engine, but cannot find any instructions or hardware. Only the nuts and plain washers holding the plastic "preservat ...

Sean, not quite. The spacer and durometers should be clamped as a rigid stack to the engine mount by the bolt if properly torqued. When the engine shakes the durometers deform in shear, allowing the d ...

Hi Sean, If the mounts are old and sagged, or the assembly is off center, additional movement from shutdown vibration can cause the bolt sleeve to knock against the inside bore of the mounts. That sho ...

Les,

The trailing edge of the upper skin was pretty wavy on my QB wings. In reflex position I measured everything between gaps of 1/8" to interference of almost 1/8" which I considered a ...

I used some of the stringer profile left over from the tail and wing kits. The J can be arranged so as not to interfere with the cutouts, or cut off with a bandsaw.

Michael,

3 times in same flight conditions seems a little suspect to pinpoint it as a sensor / electrical issue, although I would certainly follow advice and add the ground to eliminate that possib ...

Excellent tips, thanks to all.

I was just at this point in the build and have spent the evening fitting up the seat rails and looking at whether to put the plunger inboard or outboard. It struck ...

Hi Shannon,

I'm sure by now you have all the tips and tricks required. To give you more trouble deciding, here's how I did it.

Lay up a fibreglass sheet using 2 or 3 layers of thin (circa 200 ...
