Thanks,

Status: offline 		Ernie,
The Reactor kit came with a plug for this very purpose. Just let the fill line hang down out of the cowl a bit and use the plug. If you dont have the plug that came with the kit you can us a small bolt or a piece of brass tubing with one end soldered shut. If you want to get fancy a fuel dot is fine too.

Status: offline 		Guys I was able to get 4 flights in on my Reactor sunday. This is great flying little plane. It does a great slow knife edge and mine does'nt require any elevator or aileron to keep it straight. On high rates the roll rate is pretty fast. It is stable in a hover. So far I am pleased. The landing gear modification that I mentioned in a previous post worked perfect. Now the plane doesn't want to tip on its nose so easy. I'm even every very pleased with the little Magnum 70. This motor surprised me. So far it has run great and reliable and has enough power for 3d flight. Hobby Lobby has these engines on sale for 129 dollars now. Anyone wanting a four stroke on their Reactor and save a bunch of money over a Saito, OS or YS should consider this motor even though it is a little heavier that some. I still managed to get the plane to balance without adding any weight by putting the battery in the tail.

Status: offline 		Wow, great report. It seems like the Magnum 70 should be a bit lighter than a Saito 82...? Even more tail weight for the Saito 82 guys?

I think it's Hobby People that sells the Magnums.

Thanks,

Ernie

Status: online 		I got a chance to fly mine this sunday and its great. I reversed the landing gear to prevent a nose over and added take off flaps that works great. I did manage to strip an aileron servo during one of the flights. I did not notice it until the next time I fueled the plane. Got some metal gears on order for the HS 225.

Status: offline 		The Magnum 70 weighs in right at 21oz. and the Saito 82 weighs in at 17.6oz. (Both weights with mufflers.).

For an all out lightweight 3D'ing 4 stroker, the 82 is king but, the Magnum is no slouch in the power department, turning an APC 14-4W at 10K RPM's on 15% Cool Power. It's just a little heavier and a whole lot cheaper.... It's a good value and all 3 of my 70's run great but,,,, so do my Saito's...

Status: offline 		Sorry for the mistake guys it is Hobby People that has the magnum 70 for $129. Ernie the Saito 82 while having more displacement is
lighter than the Magnum 70. I have both engines. Saito is the power to weight ratio king. The Saito 82 will require less effort to get the plane to balance and have ballistic power on this plane. Howerver the Magnmum is half the price of the Saito. I already had the Magnum 70 so that is what I used and it flys the plane great. The Saito would be even better if you want to spend the extra money.

Status: offline 		OK, all you guys who are flying yours rigth now SUCK I am expecting 8+ inches of snow in the next 24 hours...

I had to go with an 8 ounce replacement tank. Any idea how much that two ounces will shorten my runs?

Also, post some pics with the landing gear reversed. I want to see how it looks before I consider doing it.

Status: offline 		Guys since everyone is seeming to have a problem with the landing gear being to far rearward I decided to post some pics of the mods I made to mine. As you can see it does't look very different. It is just rotated forward enough to keep the plane from nosing over. It requires drilling new outside holes in the gear and some slight grinding of the slot in the fusealage for the needed clearance to rotate the gear forward. You then want to bent out the toe in of the gear. All of this is very simple and easy. Some have mentioned turning the gear facing the other way. I have tried this and I didn't think it looked too great. Also the plane didnt want to come off the ground in this configuration. Stealdesk did mentioned he used flaps to get the plane airborn which is a good idea but I would rather go with my mod. Hope this helps

Just so you know, when flying off of a paved runway, I don't have any tipping problems with the stock landing gear in the stock location with the stock wheels and pants.

Status: offline 		cmala3,

A paved runway sure is nice. I used to get to fly at our local airport which is only 5 minutes from my home until the airport commission ran us off. Now I have to drive for 45 minutes to another field which is a turf farm and man you have unlimited room. Also the grass is a little more forgiving on those not so perfect landings. Grass is much less abrasive than pavement. If I had my choice though I like the paved runway. Glad to here that your plane didn't require any modification. Happy flying.

By the way, we got 7 inches of snow and more on the way... BRRRRRRRRRR....

Status: offline 		I'm on grass and am prepared to ditch the pants if necessary. In fact, I EXPECT to ditch them soon after the first few flights. I've never had a pair last on our field. However, that's an ounce or so that can be shaved, so I guess it won't bother me too much.

Status: offline 		Speaking of ounces, Bluehawk, is that a simple plastic spinner you are using? Do the nice Tru Turn type add a lot of extra nose weight? What are my options do ya think with my Saito 82? So far I've just use polished alum spinner nuts with my 82 on sport planes.

Thanks,

Ernie
