H9 30cc Spitfire & FG36 Saito


       Remove this ad - become a site supporter!
I have a FG36 that needed a home so I installed it in the new H9 Spitfire. Due to the length of the FG36 on its factory mount, I had to move the engine cowl forward 2.54cm (1 inch) which left the top hatch 6mm gap visable. To hide the 6mm gap, I made a hatch shroud to hide the gap. The shroud does not interfer with the hatch during removal or installation

Since the FG36 is installed 2.54cm (1 inch) forward of the recommended location for the other recommended engines, it should allow for less dead weight to be added to the nose to achieve the recommended C of G

The FG36 does protrude further below the engine cowl then the recommended FG30, but that is OK and acceptable to me. You will not notice how far the FG20 protudes below the engine cowl while in flight I am waiting for the E-flite retracts to arrive then I'll be able to see how much dead weight I need to add to achieve the recommended C of G location

Re: H9 30cc Spitfire & FG36 Saito

Just bought a set of E-flite retracts for my Dave Platt 1/5th Spit, you'll love the machining. Only issue with installing into the Platt wing is that the gear sit parallel to eachother, rather than angling outwards, so stance is narrower than it should be. We have a TF Spit in our club, same issues. If only the designers of kits and gear would look at a pic of a real Spit!

Re: H9 30cc Spitfire & FG36 Saito

Finally finished with the assembly of my H9 30cc Spitfire with a FG36cc Saito installed. To achieve the recommended 4 3/4" C of G, I had to add a little more dead weight to the nose than what I expected. I had calculated that it would take 14ozs but it actually took 18ozs (510.2gms) From what I remember reading, others had to add 32ozs+ to achieve the recommended C of G. I am very satisfied with the assembly and cannot wait for spring to arrive to do the maiden

Re: H9 30cc Spitfire & FG36 Saito

(Changed the C of G from 4 3/4" to 5", moved the batteries etc. It took 19oz to achieve the 5" C of G; AUW is now 19lbs 3 oz. This weight is nothing compared to a fellow flyer in the club who has the H9 Spitfire that is electric and it weights 22.5lbs. Hopefully I can get the maiden flight done this coming weekend).

Roger

I rechecked the CoG today using my new VicRC-CG'er Stand instead of the Great Planes CoG machine. The GP machine indicted I had to add 19oz of lead to achieve the 5" CoG, but the new VicRC-CG'er indicated I needed only 15oz to achieve the 5" CoG. That is a big difference 4oz of lead removed from the nose. I did the CoG test 3 times to confirm how accurate my findings were and I trust the VicRC-CG'er over the GP CoG machine. I am glad to say that the AUW of my H9 Spitfire is now only 18lbs 15oz, Yahoo!!

Re: H9 30cc Spitfire & FG36 Saito

Good luck on your maiden! On my 3Spitfires, Dynaflite, Platt, Yellow, I had to add nose weight after the maidens as they were really sensitive and hairey in pitch being a hair tail heavy. I also use the minimum elev throw for landing as too much up in the flare can really get a Spit porposing. Cheers. Ken k.

Re: H9 30cc Spitfire & FG36 Saito

This maybe of interest for those who use a seperate battery for the E-flite retracts. I left the seperate retract battery connected to the electronic control board while the Spit was stored on the rack. When I checked over the plane before loading it on the truck to take to the flying field, I noticed that the retract Life battery looked puffy. I removed it from the aircraft to check the charge and found that each cell was below 2 volts. The 2200mah Life battery is now usless/ruined, it cannot be recharged. Apparently the electronic control board will draw power from the battery when left connected unless you have an on off switch placed between the battery and control board

Re: H9 30cc Spitfire & FG36 Saito

I finally achieved the maiden flight today, including several follow on flights. The Spitfire only required 1 click of nose up elevator with no aileron trim needed. When flaps were deployed there was no pitch up or pitch down at all. The FG-36cc Saito has plenty of power and is a good match for the airframe. I removed another 1.5ozs of lead from the nose, my CG is now 5 & 1/16" (129mm) from the leading edge of the wing. She flys perfectly at this CG, and that's where I will leave it. The total amount of dead weight I now have at the nose is 13.5ozs, the AUW of the Spitfire before fuel is added is now 18lbs 13.5 ozs.

Doing scale take offs is easy with a little right rudder applied as power is increased, it had no tendancy to want to nose over on take off or landing. On landing it rolled straight as long as one keeps on the rudder until the tail wheel settles on the ground. I will fine tune the FG-36 as I get more flights in, it seems to be slightly rich as indicated during the follow on flights today. I am one happy H9 30cc Spitfire owner.

Roger

Re: H9 30cc Spitfire & FG36 Saito

Congrats on the successful maiden and subsequent flights Roger. I have the FG36 for my H9 Spit as well so this information is very interesting to me. Thanks for sharing.
