Another source of temperature spikes I have found is with the absolute junk VDO gauges that tend to develop erratic needle swings as they age. I spent one summer changing out well over 1000 dollars w ...

A very simple answer Perry, DON'T

The 750 firewall is substantially different than the 701. Additionally, the 701 has a max recommended firewall weight of 200 lbs and the O-200 is around 240lbs. ...

Perry, I have diagonal stiffeners in my 701 and they help but I still get some rattle in certain fligh conditions. It is telling that the diagonals are stock on the 750 so if I were building a 701 ag ...

Yes, I am able to get the bolts out but the bottom one is a bit nasty to get.

I don't have any pics right now but if you do put an inspection panel in, be careful not to go too far forward as t ...

I put an inspection panel adjacent to where the strut enters the wing so that I can inspect those bolts at every annual.

Frank, I would not want to comment on the structural changes you are proposing for your plane beyond saying proceed with extreme caution because you are stepping way outside the original design envelo ...

Bobby, we are dealing with a similar issue up hear in the recently "Great White North" of Northwestern Ontario. As a solution on my buddy's STOL 750/3300 we took a small 6"x10" ce ...

I found the factory rigging to not be quite enough of a droop on the flapperons. My plane seemed to be plowing through the air slightly in cruise with the factory settings and even after I installed ...

All applicable kudos to Roger if he does decide to produce a gauge set for syncing 912/914 carbs but it would be a redundant product. Lockwood sells a very nice analog gauge set with applicable hoses ...

Kyle, I'm not sure if I'm the Doug you are referring to or not but I had a similar issue with my engine when I first started running it on my plane and the issue was the chokes were not closed complet ...

I was figuratively biting my tongue, hoping this topic would go away without killing anyone but seeing so many responses in the Daily Digest I decided to add my two cents. Forgive me if I come across ...

The only way that I have heard of the bubble doors failing in flight is if the latch pops and one opens up into the slipstream. That is why I suggested supplementary latches as a potential solution ( ...

If you are worried about the 701 doors coming off in flight I would recommend contacting Zenith and getting the latch kit for the 750. The 750 door is a bit larger and has three latch points as oppos ...

For those who are having trouble with the Matco tubeless tires leaking air at the split rim, I have found that if you coat the o-ring at the split in the rim with spray lithium grease the leaks go awa ...

Clearance issues on the top; there would end up being a bulge in the top skin to clear the sending units.

I did my senders on the sides of the tanks on my 701 and have had no issues with leaks. We ...

Perry, the fiberglass tips on the 701 are at best a pain in the backside.

First trick is to realize the top rear point does not line up with the spar tip but ends up 10-15 mm behind the spar (i ...

You'll need inserts too.

Perry, I picked up an economical rivet squeezer from one of the aviation tool supply houses(Avery I think) for a fairly reasonable price. It may work to squeeze the soft trailing edge rivets with mod ...

I don't know what to tell you Perry other than the flatter and truer the work surface, the better the final product will be. I would to my best to eliminate the twist as much as possible. Now, are w ...

That is what I have on mine and thought everyone also did since B-K was giving them away for free at one time. Three hours at full brightness is typical battery life on my good ole AV8OR.
