    Okie, im attempting to retune this thing and after warming it up heres whats happening. From a stop, giving throttle its pretty sluggish from idle to about mid rpm and once it hits mid rpm it runs fine and takes off. this is both easing the throttle and jamming on the throttle. Also when spooling down once it hits mid rpm it stalls. Im thinking lean the low speed needle but i want to double check before i start leaning it out. I started with the HSN rich... it wasnt passing mid rpm at first so i started leaning the HSN untill it started taking off at mid rpm range, still sluggish at low rpm though. Lookin for some feedback

    Thanks

    PS: I checked the needle turns and the HSN was out about 3 1/2 turns and the LSN was out around 3 turns with the muffler side screw in as far as it can go.


    ADD:

    I think im about finished for the day. I've had 2 glow plugs go sour on me in the past hour or so. I took a look at them and the coil was a bit out of shape but as i understand it that is an indicator of a very lean setting, but I have my LSN out a good deal and same with the HSN. I planned on working from a rich to lean setting after the motor warmed... I was getting a bit of blue smoke at idle and a good deal of it when i tried throttling which also told me i was set rich, but why would the coil in the plug be bent out some? If anything is open today i'll go get another plug, but untill then im benched for the day.

    Hey Buggygovroom-

    Yes the LSN is definitely rich. That is why it's in the first portion of the acceleration. Also 3 turns should be WAY too much. I believe mine is more at about 2 or maybe 1 3/4. The pinching the fuel line test works pretty well for figuring out your lowspeed adj, but be sure you are doing it close to where the fuel enters the carb. If you do it too far away it's just burning the fuel in the line. But I've found when you are doing it close it should take about 3 sec to die. That will get you close to where you need to be and then you can fine tune it later if you need to.

    They Testy-

    I can't say enough how good of a car this is. I am pretty new to the hobby but I do a LOT of research on things before I step in or recommend. I started with a smartech which has been fun and helped me get into the hobby cheap and see if I would enjoy it, I have an OFNA 9.5, and the Himoto Torpeda Pro (.27 engine). I can honestly say the Himoto has been the best of them. The OFNA I've had a lot of trouble with but didn't buy new, but I do have it going now and it drives no better than the Himoto. The Himoto has just as solid looking parts. The shock towers are thinner on the Himoto BUT they are the SAME size as on the Kyosho 7.5. I've flipped end over end (having it hit once bounce up 2-3ft, and continue to flip several more times) I've had it cartwheel 6-7 times in a row on a single spill etc and so on, and have NOT broke ONE piece. I know I'm due. Because I hear people with their $700 Hyper 7 and Jammin's breaking things eventually too. But so far I have not been nice to this thing at all and it has not let me down.

    A thing to remember (for everyone thinking of buying one) about the people who buy other cars and bash these because they don't' know about them. Imagine you just spent all this time thinking about buying a car. You went with one that was $500-700 because you weren't sure if another one was going to be good. So know you have your wonderful new car and someone asks about a $250 car and if it's good. Of course you are going to say !QUOT!no, it sucks!QUOT! and bash it because you have to rationalize your purchase to yourself, or you would feel like you wasted $250+.

    Finally on the flip side, are their better cars? Yes. For the money? I really believe no. For a little more money? Probably not. If you want to spend $700-$1000 then of course you will get a better car. As things lie in the subtleties, but when you're a newbie you don't even know yet what you are going to need.

    Great beginner car for sure and be sure to check out Laughing Potato's post about winnin 6th place in competition with his. This isn't just a bashing car if you know what you are doing. This was his first go in comp with a buggy I believe. Used it STOCK vs everyone's $1000 cars.

    Last 2 issues you asked about - Parts you can get fairly easily from several on-line vendors at this point and they are competitively priced (Most of the time my Hobby shop doesn't have the part I NEED and has to !QUOT!order!QUOT! it in for a week. I can !QUOT!order!QUOT! it myself without traveling to the shop).

    Lastly - I don't know yet about the Kyosho parts and others mixing because I haven't broken anything. When I do I'm going to see how the Kyosho stuff fits. I can say this - I was at the LHS and saw the 7.5 side by side and these things looked almost exactly alike. The front arms are different, but other stuff looked like it would be exact fit but I DON'T know yet. OFNA Wheels and tire nuts fit

    Good luck man - hope to see you in here adding info on what you can do with these things. It's growin all the time.

    Hey Guys

    Does anyone know if we will be able to get parts to rebuild the engine? I plan on running this thing hard and just rebuilding when I need to.

    BTW for those wanting to change the throttle servo out (if you decide to) I ran into problems becuase the clearance of the HiTec645MG Servo arm to the Servo body was smaller than the clearance of the STOCK servo. So what I did was sand down the plastic piece about 1/16th of an inch on both sides of the lower break shaft, so it would fit in there with clearance. I'm sure the other thing you could do is buy a part from an ofna or other car that has the front and back breaks connect to a seperate joint and then attach to the servo.

    Anyway - just wanted to post the workaround for it.

    Hey BGV.

    I'm sure it's too rich. Turn the HSN out about 3 and ther LS out about 2 as a starting point.

    If you have a temp gun this helps too but use your ears too.

    If you had the HS lean at one point and the LS rich this could have given you your false reading on the Glowplug I think.

    OH - Hey Testy

    I forgot to add don't judge them on the 1/10th trucks. Those seem to be problematic. But going through you won't find any reporst of problems (that I have ever found) iwth the 1/8th buggies.

    Also - remember a lot of times people buying these entry level cars are inexperienced so what seems like more trouble tuning, or basic things are actually just do to them being new giving it the since that they are hard to tune etc.

    HI Trpastor
    I've been researching for about a week and what you said is exactly what I wished to hear..Its one thing for a salesman to recommend a car but it is another thing to hear it from an actual user. Thanks, I really, really appreciate it. Well I guess its off to the virtual shop for me to buy my new toy...YEAH!!!!

    My buddy has his smashed up kyosho mp 7.5 here, i tried a few things and most of the stuff seems to fit. the wheels and nuts, the bumper. the steering turnbuckles. front and rear suspension arms, wing, body, shocks all switched out. My new car is a redcat with kyosho plastic, hah! I wish i coulda taken the motor.. it was a rossi gold .21 long stroke. oh well. I got some wheels and tires comin too. and picked up an extra set of rims with street tires for the lazy days i dont feel like leaving the side streets im going to pick up some new glow plugs and gas tomorrow... gonna see if this tuning issue will work out.

    Later

    Hey BGV-

    That's cool. I'd love to see a pic if you can upload one or two. So does it sit differently now? How do the shocks and everything conduct on the new arms?

    I ask becasue the redcat/himoto's seem to bend down toward the tires at the end and the Kyosho's didn't. See photo

    Also - I'm assuming the "steering Knuckels" didn't fit as (from what I saw on the Kyosho) the upper and lower arm came in directly on top of each other, where as the himoto's are slightly off set (see image).

    Thanks for the input!! Send us a pic of this hybrid

    So do you think you could effectively "mix" pieces in the upper arms or would it have to be all or none??
