That's right. Well, almost. With just the Laminova I get a delta-T of 10C. So, you can get your coolant up to 110C and the oil will stabilize at 120C. Note that this is rock steady, if the oil would
A cowl flap has the same effect. But a cowl flap has the additional advantage that you block off the unnecessary air flow through the radiator. Dragging air through a radiator comes with an aerodynam
Hi everyone, I got numerous requests for pictures, so I assume this is of "general interest". I still plan to write an article about this, but so far I didn't find the time. So, for all of you who ar
I have the largest diameter available (I don't remember how much that is). In fact, I had to extent the nose wheel shaft to keep enough clearance margin on a rough strip with a flat tire. The prop pe
This custom made radiator is made by a Czech company, www.aluminiumracing.com (see their pictures of Rotax radiators). This is basically the "standard" Rotax radiator, as recommended by Rotax and use
I think it is, but of course it is hard to measure and judge. We also have an efficient prop and Fred Klein's wing root fairings. On the other hand the aircraft is a tri-gear, hi-top, and quite heavy
Of course you also need the Laminova heat exchanger. I hope you didn't suffer too much other damage? What is a "rolling" farm field? What was the reason of the forced landing? Guess it is. If you rea
As far as I know it can be somewhat tricky to connect two tacho's at the same time. It is a weird interface, nor digital nor analogue. You can't trust either of them. If you really want to know, you'
I have them too, I installed them with the knob pointing towards the tail. They are working perfectly, the airstream is adjustable to all positions. I have also installed an overhead vent, which is g
Hi Remi, I had a hose connected to the outlet of the D-panel, all the way to the sternpost. No air from the rear fuselage could get into the hose. The interesting thing is that the sternpost (actuall
Apart from that they are not pushed fully home, as some others have mentioned, I see a few more worrying things. First, these wires should go to your ignition-switch and nowhere else. But within a ve
To avoid this problem I welded two vertical bars to my build craddle with adjustable ends, so I could attach an artificial floor straight edge to it, and adjust everything independantly from the floo
of intake There are a few reasons to keep the engine temperature higher: 1) Wear of the engine. Different parts of the engine expand at different rates when the engine gets warmer. Ideally, you have
This is often the case if you don't run the engine. The turbo is at a low position, there is a valve in the oil return line but even a tiny leak in that valve will allow the oil slowly to collect in
Humbug. Go for the antenna as proposed in the build manual. That is a half wave dipole, correctly polarized, and there is just nothing that can beat a vertical half wave antenna in an aircraft. No an
I recently wrote a private message to someone else about this subject. You may be interested in it: I have not earthed it at all, I even didn't use shielded cable. I think the diagram only shows it t
We are not talking here about the HT-leads to the spark plugs, but about the ignition kill wire. I'm sure you must have been impressed ;-), but the Rotax ignition kill circuit is far from comparable

Reason of this is that if it is exactly circular, it resonates at exactly one frequency, i.e. it is very narrow banded. The transmitting and receiving of the transponders is on different frequencies,
