test flew my pst 54 yesterday. 4 solid flights. p 70 for power. no pst nose weight required with this set up. i used 2 2400 4.8 nicads, jetcat 4000mah duralite and a 6v 1100 for the smoke pump, all in the nose. i, also, made a wheel well for the nose strut. it is hidden away from all the coming and goings inside the fuse. i painted the inside white after test fitting the install. she uses the main pst tank with an extra 24oz added. she has a 32 oz for smoke. i didnt use the alluminum heat shield. instead, i added a balsa bulkhead and used flite metal for a heat shield. it lands every bit as easy as my kit r54. i think the stabs with an airfoil makes her groove better then the kit version. the p70 offers almost unlimited vertical and long flights while keeping the model fairly lite. barry

Good move about the nose wheel-well Barry. I thought about doing that myself for fear of kicking up junk via the spinning nose wheel and getting it ingested into the engine.

I haven't started the assembly yet and I'm still on the fence on whether to use a P-70 or P-80, but I will have smoke and a speed brake.

i have no speed brake. maybe the larger turbines with residual thrust may need one, but not 20 lbs or less. the flaps are huge and can droop down almost to 90 degrees. i am coming in at about 3 clicks up from idle and it is at a crawl. by far, the slowest landing jet around. barry

Hi,
the two tanks up front are your own or the supplied tanks ? I am going to run a S/Sport and no smoke at present so I am looking for the lightest installation. I believe my kit (not yet arrived but soon ) will have a 3.5 lt tank and whilst I can partially fill this another tank sytemem might be worthwhile considering.
Thanks

David

skywarrior, mine is an early kit. i think the new kits have a larger main tank. but i added a 24 oz and a 36 oz. one for smoke and one for extra fuel. barry

Actually not. Take off with out flaps and this wasn't my best landing neither. I extended a little bit to get out of the grass.

Nice Alex. What do you have for a smoke pump and did you use 1 or 2 nozzles?

Barry, I know you have a Sullivan smoke pump in it from past pic/posts, but it's not clear if ya got a second nozzle at the burner.
I'm undecided on either a Tam unit or Sullivan smoker. I've heard good stuff about both rigs.

The 'aluminum' leading edge is nice... is it foil tape ?

i had a sullivan laying around, but no nozzles. i made some brass ones. i didnt place them directly into the blast. instead, i got them close and aimed them at the blast. no worky. i have tam nozzles on the way. i use tam in all of my models for smoke and they are excellent. i may, if not pleased with the sullivan, change out the pump. barry

Mike I'm also using a sulivan skywriter smoke pump with two 1/8 brass tubing for injectors. Instead of using a tip of a xacto blade to make the sprayers I insert a small shim of alum from soda or beer can as a gage. Both tips are in the hottest spot of turbine blast. The pump was powered with a 6volts nimh batt. but I upgrade it to 11.1v. lipo and now got better smoke.

Regrads,
Alex

hello jay, i used rc car paint. the color is sprint white. i think it is a testors or pactra product. it is nitro fuel proof, so it is ok for the job. it sprays and covers fast. it is thin and light. i went with white, because the reaction i have is gel coated in white and i felt darker colors would darken the exterior. i will have this jet flying at pensacola. stop by and say hello if anyone is at the event. barry

Hey Barry, how are you doing? R U going to TG next year? I hope to see you there.

We are having a blast with the Reactions. Mine has a 1600R and it has a few fun mods. I am working on getting good smoke using diesel and ATF but so far not happy with the results. I am used to dri smoke but it is not available at the moment.

We clocked one at about 280 kph w/1300R, but the 1600R gives it really out of sight rolls. Kraivuth thinks I am crazy[8D] with my 1600R one.. This jet lends itself to a lot of mods and options since it carries its weight very well. Mine must be an easy 6 lbs heavier due to all the stuff in it and it flys trim free and just as well as the 800R equiped ones, I do not know how? (must be the airfoil)...

what sort of mods do you have on your reaction Ehab? I was hoping there were some hard points for ordinance, I think it will carry it just fine. hoping for maiden this weekend with p-120 for power.

Hi ,
does the$150 discount apply to kits only without retract sets?

I have just received mine and overall its very good. I did find that the flaps were not glued to the outer skin at all on one side and the other was very sparse. I have one major query though I am not using the PST gear units, I had two reversed Robart 630 which fitted the mains quite well (with a little mod to the woodwork also see this thread), however when I came to the nose wheel retract I am using an Airpower unit which is 46 mm across the fixing holes plus surrounding metal. ( I believe this is the same as your 40 lb retract unit or indeed very similar. The problem is the nose wheel mounting rails are cut away to only accommodate your smaller 20lb unit which is only 26 mm across the fixing holes. Surely this must be marginal with a model weighing in at 24lbs plus? However I cannot see the logic in restricting the mounting of retract units to just one manufacturer. I am sure the PST units are very good but a lot of us out here have a drawer full of other stuff we may want to fit and not purchase from new.
I have not seen any reference to this on this thread so does that mean this is a new version or is everyone using PST gear units?

If the rails had been made parallel any unit would fit so I cannot see the reason other than to restrict the fitting of retract gear ( nose wheel) to your own manufacture.
This is not made clear in any articles or ads I have seen so far and is kind of off putting when you have such a great airplane if this is the case!
I have now removed the old rails and fitted two new ones which work fine but I could have done without the excercise.

PS I have enclosed a shot of the Airpower unit showing the shortfall in the rails + a shot of the nose of my model showing a cutout panel in base with 3 x 2 cell Lipos .. one BVM trap and yet to fit one Wren pump for the Super Sport. I have left enough room to put whatever lead is necessary in the nose from the supplied block. It will be interesting to see how much is needed. I hope none. The Lipos and trap weigh 400 gram

Regards

David

David, in mine I used an old set of robart 630 with Kangaroo struts. I reversed the mains retracts and for the nose just drill a new hole between the two all ready made in order to screw it to the rails. No mod necessary for me. Well unfortunatly the nose strut died today casue of another of my famous hard landigs So I will go ahead and order a new set of the prolinks struts from Todd. After my experience with the trailing link struts in my old boomerang I think no other leg can resit my punisment. Hope to have it ready for next weekend cause this one is over for me. Today was a perfect day until I get to the filed. As soon I finished fuelling her up it started to rain. When rain ended few thunders keep me grounded. Finally a good spot of sun shine hit the run way and up she went. At take off, wind dropped and when time to land arrived wind change direction giving me a south cross wing with some gust about 20 miles. Forget to tell for being laisy and for not removing the wing to inspect flaps connection I decide to go with out flaps. But the climate conditions made my plane fly faster than other days and the speed brake din't help me much with the wind conditions. Another Lesson learned. Plane still in one piece though.
