hi steven and tara
i just got back from vancouver so i will try to send some pictures by monday
i was looking at how long it took to make my main gear spring ,once i had made the dies it took 8 hours to prep and bend the flat bar . our shop rate is $80.00 hr so you would be looking at $640.00 plus tax and material .
I think the flat bar was around $100.00
its already mounted under the plane but i will get some pictures of it for you
the flat bar gets sanded to remove any scratches ,then the corners get routered from just under the cab all the way down to the end by the wheels ,then i gets sanded again ,then bent then finaly palm sanded
Do you know if the 750 main gear is made heavier as i mentioned in my last e mail 3.5 intead of 3.25 somthing to check out .
by for now

Hi steven and tara
yes thats all i did i made the floor pan wider the channel for the landing gear, the cross member behind your head and the controll arms that the alerons are attaches to all need to be longer when you make the two horizontal control arms becareful to make them the same ratio as original or you will have a twitchy or not so twitch control yoke . other than that the side skins of the rear fusalage are longer the bottom and top skins i made 5 inches wider and kept the slight curve on the longerons in both upand down direction . i also made my fire wall and dash 2 inches wider just to smooth the transition from the rear post to the cowling ,i didnt want it to be joggy ,it turned out great .
just made some dies to bend the landing gear ,and have installed it under the plane ,thats another thing you will have to deal with it will also need to be wider
what i did was i made the angle 65 deg instead of 60 ged bends because the longer the main gear is the softer the spring will be ,so i stood up the angle a little
if you are making it 8 inches wider you may want to make the landing gear 3.5 inches wide instead of 3.25 inches because the extra lenth will soften that landing gear spring a little more than what i got
If you go with a wider main gear flat bar you will have to make the channel wider and also make new wing strut pickups
and the cabin side skins will have to be .25 inches longer
every time you change somthing you have to follow it through the plans to see what it will affect, but its not hard you just need to take you time and figure it out
anywhay i could talk for hours if you are taking on this prodject you probably already know all this stuff, its good to talk to some one who is doing something similar
I will send some pictures asap thanks and keep in touch

The motor mount is the basic701 912 mount, modified to meet the rx 1 engine @ 3 degrees off center at the prop and at the height you desire. What is your plan for the psru?

The engine is running fine but I have not tested it with the prop on .This will be done in the spring. no place to work in the winter

Steve, I know the work I put into placing the Suzuki on the firewall and I can see you have a project ahead of you. I work for Arctic Cat snowmobile company so a $25,000 dollar rotax motor would not go over good here. My motor was $1,000 and the redrive was $4,500 which came from Raven redrive and they work great. My motor is a turbo 660 from a sled and I turned it down to 112 hp at 6300 rpm's for takeoff and about 5500-5700 at cruise with 95 lbs of torque. The only two problems I had was engine oil cooling and intercooler being too small. I have at this time 67 hours on the motor. Later Al Shimpa
