Wile E, could you look at the link in my post above and let me know if the prop on that 1/48 scale model matches what you saw in that book. thanks. For some reason I can't copy that pic.

SpeedPro, how do you like your MPI onboard glow? I am thinking about getting one. I have an OS 120
that runs great but wont idle for anything since it is inverted. I have it on a GP Ryan sta.
It wants to deadstick on landing approach. I tried a Nelson oboard glow but in my opinion they are not
very good. Does the mpi have the ability to only come on at idle?

Thanks, airplaneman

Airplaneman,
I use the RAM 50 with my OS120 that I have in my GeeBee, and I've also used it on a OS91 on my AutoGyro and I have it installed on my P-6e. I've had no issues with the RAM and my OS 120 is inverted. You can adjust the cutoff/on point to your liking. My GeeBee will idle very nicely with this and It sure makes it easy to start. I have it set to come on about 1/4 throttle.

The RAM has issues with some low signal futaba RX, but mine works fine with the 127DF receivers which is what I'm using in most of my planes.

so far so good.this is my first on board glow system the mpi unit i bought came with a 1900mah cell and charger which they have you doing all the wiring you have to cut the end off the charger and install new end which they supplied. yes its easy to program just hold down the button on the unit turn on the receiver led starts flashing release button move the throttle stick to your glow on/off position....about 1/4 stick repress the units button again and hold button down then move to full throttle and release button done. the unit then lights the glow plug below the stick position you programed.you can also flip the ch 5 switch and override the unit and turn on the glow all the time. during engine break in i had the glow running all the time and lasted about 1 hour on thier batt. i took thier battery off and build me a 6600 mah hour battery using two gp sub c cell 3300 mah batts wired in parallel I also use my on charger( astro 110) to charge the cells ( in the cockpit ) since thier supplied 250mah charger would take forever to charge my home made pack. the mpi also kills power to the glow plug anytime the transmitter or receiver is turn off but i still have the kill switch mounted tucked under the cowling at the bottom which they also supply.

Correct me if I'm wrong but connecting two 3300 mAh batteries in parallel results in a two-cell 3300 mAh pack, not a 6600 mAh pack. A minor detail to be sure... that is, until you try to quick charge at 2C. Keep a fire extinguisher handy [8D]

Three more flights on the Hawk today and it just keeps getting better. Conditions were VERY windy with gusts in the 25 mph range and blowing across the runway at 90 degrees. The airplane handles wind with ease and is rock solid even in gusty conditions. Landings were great fun with the plane flying almost sideways all the way to touchdown. Just a shot of rudder as the wheels touched was all it took. Great Plane indeed

Man I'm jealous! STILL waiting on my metric bolts to arrive from Microfasteners so I can mount that RCV! BTW....has anyone flown this with the RCV yet?

Mine's all done, including the flying wires, just sitting there waiting on the engine to be finally mounted and to be balanced. I've started looking at the cowl to decide how I'm going to increase airflow over the RCV. I'll post pics when I'm done.....If I ever get the bolts!

Oh...chick out my new avatar!

connecting up two 3300 nmhd in series result in a 2.4 volt 3300mah batt. connecting the two 3300 cells in parrallel (positive to positive neg to neg) results in 1.2 volt 6600mah.

If you are talking about the below pic; it is of the real Hawk in the AF Museaum. Otherwise, I'm not sure which pic you mean.

SPLAIS,

The illustration in the book was a cross-sectional drawing and just labelled the prop as a Hamilton Standard. There was no drawing of a logo on the blades.

Steve S., what did you use for flying wires? If commercially available, where did you buy them? Thanks.

Build (continued)

Pic 68:
I ordered a 90 degree exhaust elbow for my OS 1.20 4-stroke so the muffler will exit out the large hole in the back of the cowl.
Until Spring, she's hanging from the ceiling along with her other friends.
After doing a P-38 and P-61 with retracts, functional doors, flaps, dual motors, etc,
it's nice to get a plane done in only several days instead of weeks!

Frank,
I used the elastic beading cord just as the directions state, however, I made hooks to attach mine to the fuselage. I took black Number 1 hooks from the fabric store and put the hook end in the fuselage. Just cut a small slot with a knife, put some Med CA on the hook and stuck it in. It's so small and black that you don't even see it. I then modified the hook end slightly (it has two loops, I removed one) and attached the cord. Now I can replace the cords without any fuss.

Thanks, Steve, the hook idea appeals to me. It sounds like a very neat way to handle the cord.

Got the engine spacers and bolts from McMasters today. Here's a test fit of the cowling with the engine mounted. Looks just like the test drawing. I cut out the bottom panel in the cowl so I could better fit the cylinder head and in case I need a quieter muffler, I can mount things without cutting needless exaust holes in the cowl.

Wile E,
You are going to make that panel replaceable, right? It wouldn't look very good left open like that all the time.

I was looking at the squadron photo(post#342 on page 14) and didnt notice until I looked again. Did Anyone notice how close they are to each other? That is impressive! Even th best aerobatic pilots in the world are lucky to get that close. I wonder if their wings ever touched?

FINALLY....got my longer metric bolts tonight so the RCV is on the front! Now all I need is the Keleo exhaust! Don't know how much the exhaust is gonna weigh, but with the RCV stuck way out front and everything else inside I'm still tail heavy. I've got the APC 3 blade props on order (15.75x13) that may help some.

Anyone notice the top wing stripes?
It looks like that only the one in the center front has 3 stripes, while the middle 3 have 1 stripe and that MAYBE the center plane in the last row MAY have had two stripes.

Could this be where GP got the '2 stripe' marking for the top wing?

Those guys were among the cream of the crop at that time. Probably some of the best pilots in the world -- at that time.
