It come with a padded bag and weight about 10 Lbs. I put the fan in at the bottom cowling and the hot air exit at the top cowling (at the oil check door or front cowling) and within 10 minutes my engine is warm. 2 things; it is a open flame near fuel system and you have to protect it somehow when it's windy because the wind will put the flame out.

His pre heat was to stick a hose over the exhaust of the tractor and stuff the other end in the air intake. This was in the winter and it sometimes gets quite chilly up here in the frozen north. Seemed to work and this was a "no electrics cub" as in hand swing that prop. That was fine for the engine, the driver had to dress for the occasion since there was no heat in the cabin and a J3 cabin can get lots of fresh air wafting though. Funny part about this particular a/c was that when it started you didn't dare touch the throttle until it had warmed up a bit. If you did it would quit and you would have a great deal of difficulty getting it started again. I read somewhere that the reason was that the moisture in the mixture would freeze and foul the plugs. No idea if this is fact or not alex t ________________________________ Message 3 _____________________________________ Time: 06:38:55 AM PST US From: "Jim Pellien" Subject: RE: Zenith-List: Pre-Heating a 601 --> Zenith-List message posted by: "Jim Pellien" Larry, Thanks for the thoughts about an electic pre-heater.

It would need a set of wheels 2-foot ground extensions for stability and a weather proof cord all to keep wetness out but it could be done. Nice thing about this type of heater is that if it gets kicked over it shuts off too. If the winds get nasty, you could even stake it down. Then you'd have to plug up your cowl but for one screened opening on the bottom to keep the field mice out of it. Don't give up on it. I think you could do it, if you have a plug-in somewhere close by. Larry Jim Pellien wrote: >--> Zenith-List message posted by: "Jim Pellien" > >Larry, > >My aircraft is not hangered.

Put a blanket, or something, over the cowling to cover up the air inlets and the system works very well.

I'm close enough to finishing that I'd like to start getting some time in a 601. I'm a Private Pilot with Instrument rating and 500+ hours mostly in a 172M. I'm "local" to Sky Bryce or other area airports. I suspect others may be interested too.

This first aircraft (side number N601VA) was delivered to me on Friday 7 October. I flew the airplane back to Virginia with my Mid-Atlantic Sports Planes Chief Pilot, Nathan Mayers. This beautiful airplane will be used in our 1-week Sport Pilot Immersive Flight School at the Bryce Mountain Resort in Virginia. Statistics and Performance with a Rotax 912S 100 hp engine: Empty Weight: 728 lbs (from actual weight and balance for N601VA) Gross Takeoff Weight: 1320 lbs Actual Useful Load: 592 lbs Fuel Capacity: 30 gallons (29 useable) 180 lbs Useful Load with Full Fuel: 412 lbs Useful Load with 15 gallons of fuel: 502 lbs On the flight from Lakeland, FL to Virginia we were able to reach 130 mph Max Continuous Cruise Speed (true airspeed) at 5500 RPM. We also took this beautiful performing bird up to 13,500 feet. We averaged 4.9 gallons per hour for the entire trip. We got 125 mph True Airspeed at 5200 RPM. My estimation of maximum range with 30 minute reserves, given the performance on this trip, would be 662 miles over a 5.3 hour trip (5 gallons per hour at 125 mph, 29 gallons useable, 30 minute reserve). The bird had plenty of baggage space with two wing lockers and a cavernouse storage area behind the seats. I am more than pleased with "N601VA".....it will be a great workhorse for our flight school and for rentals. Our first Sport Pilot School student is coming tomorrow for a week.

I went and got my manual out of the box of the brand new 912S that I just had shipped to me 3 weeks ago and the diagram actually shows the hose going from the water pump to the top of the radiator (as I had it installed on my 912UL). I have also seen the hoses ran the other way with no adverse affects. I was in error on one assumption however, instead of the coolant going from the water pump to the radiator, it actually goes the other direction and is pumped directly into the heads on the engine. BTW, my local A&P deals primarily with certificated engines such as Continental & Lycoming, so if you have knowledge concerning Rotax engines and their cooling systems that is not included in the manuals, I am sure that I am not the only one that would be interested in hearing it.

I have the new piece but I'm not sure if it only takes bolts through the bottom plate of the gear leg or if it also has some through the sides into the original fork or not. Seems like it has to have more than just those on top to be effective, but I notice the HD drawings don't show any. Anyone have an idea?

However, I would suspect that if the coolant has gotten that low you will already be seeing indications of overheating on your cylinder head or oil temp gages. That said, I believe I may be routing my lines the other way after all. Will just have to ask a few more questions to the guys that work with these systems daily. Happy Holidays to alla y'all.

You need a little longer bolt that the AN4-7A called for on the original drawing 6-G-1. Also there are two bolts on the sides of the fork (total of 4) about 10mm up from the bottom of the reenforcement. All these bolts should be included in the package with the fork reenforcement. I don't have the installation instructions with me but hope this helps.

Be sure to firmly bolt the doubler and original fork together at the top before drilling the holes for those bolts.
